　　Equipment renewal and trade-in of consumer goods can increase advanced production capacity, improve production efficiency, promote energy saving and carbon reduction, eliminate potential safety hazards, and play an important role in promoting high-end, intelligent and green development of the industry, which is beneficial to both enterprises and people’s livelihood, and is beneficial to both the present and the long-term, stable growth and transformation.

　　On April 28th, the municipal government officially issued the Action Plan for Beijing to Actively Promote Equipment Renewal and Trade-in of Consumer Goods (hereinafter referred to as the Action Plan), which made overall arrangements for Beijing to carry out equipment renewal and trade-in of consumer goods.

　　The Municipal Development and Reform Commission, together with the Municipal Bureau of Commerce, the Municipal Urban Management Committee, the Municipal Bureau of Economic and Information Technology, the Municipal Market Supervision Bureau and the Municipal Housing and Urban-Rural Development Committee, held a policy interpretation meeting to comprehensively introduce the main contents of the Action Plan and answer questions from reporters.

　　What are the considerations in the formulation of the Action Plan? What are the main contents?

　　There is a large amount of space for renewal and replacement.

　　Machinery and equipment are the backbone of Beijing’s infrastructure, public services and industrial system, and durable consumer goods are directly related to the quality of life of citizens. After more than 40 years of development since the reform and opening up, Beijing has accumulated a wealth of machinery and equipment, which entered the peak period of upgrading existing assets earlier than the whole country.

　　At the same time, as a super-large city, Beijing has a large number of durable consumer goods. It is estimated that by 2023, there will be more than 50 million household appliances such as televisions, air conditioners, refrigerators, washing machines and computers. There are about 7.6 million motor vehicles in the city, more than 1,200 subway trains, 8 lines that have been in operation for more than 15 years, and a large number of equipment in various urban public facilities and enterprise production facilities, which contains great demand for upgrading.

　　Driven by scientific and technological innovation, the demand for transformation and development and consumption upgrading will be further enhanced. Actively promoting the renewal of equipment and trade-in of consumer goods in Beijing is an important measure to thoroughly implement the relevant decision-making arrangements of the CPC Central Committee and the State Council, adapt to the development requirements of the capital in the new era, and meet the growing needs of citizens for a better life.

　　Focus on "Five Points" to Reflect Safety, Green, Intelligence and Quality

　　The Action Plan highlights the basic principles of standard traction, classification promotion, precision and science, and universal access, fully embodies the basic orientation of safety, green, intelligence and quality, and mainly focuses on the following five points:

　　1. Give priority to further improving the level of public services.

　　In view of the operation of urban infrastructure, public safety and public service guarantee, as well as the weak links in the field of people’s livelihood, we will speed up the pace of upgrading facilities and equipment in related fields and improve the level of public services.

　　2. Highlight pollution reduction and carbon reduction to promote green development

　　Combined with the characteristics of pollutants and carbon emissions in Beijing, we will focus on key areas, speed up the upgrading of equipment and the upgrading of factories and stations, help to continuously improve the quality of the ecological environment and promote the green development of the industry.

　　3. Pay attention to the improvement of citizens’ quality of life

　　Promote residents’ willingness to renew durable consumer goods with old ones. Support the renewal of education and medical facilities and equipment.

　　4. Insist on upgrading equipment and products by upgrading standards.

　　Encourage innovation in products and services, business models and financial support.

　　5. Improve the recycling network of waste products and equipment.

　　Support the circulation of second-hand goods, promote the high-level recycling of resources, and improve the whole chain of trade-in for new ones.

　　Policy in different fields

　　Safeguard measures involving five major areas and three aspects

　　The Action Plan includes six aspects and 23 specific measures in terms of content, and five major areas in terms of subdivision, and puts forward three safeguard measures:

　　1. Infrastructure field

　　We will implement equipment renovation in the fields of rail transit, water, electricity and heat in batches, accelerate the promotion of all kinds of equipment and software with high safety and intelligence, and further improve the safety and intelligence of infrastructure and the level of green and low carbon.

　　For example, the Municipal Heating Group plans to implement the third-phase renovation project of the old heating pipe network and facilities in Anhuili Community, Chaoyang District. It plans to renovate the primary heating pipeline of about 380 meters, the secondary heating pipeline of about 19,000 meters, the indoor public pipeline of 35,000 meters, and 12 heating stations, and simultaneously install intelligent equipment such as Internet of Things collection terminals and room temperature collectors. It is estimated that after the implementation, the water leakage will be reduced by 17,000 tons per heating season, the energy will be saved by about 2,400 tons of standard coal, and the carbon emissions will be reduced by about 4,200 tons

　　2. Public safety and public services

　　In accordance with the relevant standards of "multi-pole integration and multi-sense integration", the integration and upgrading of roadside poles, sensing equipment, signal lights and street lamps will be promoted as a whole. Promote the renewal of old residential elevators and the installation of elevators in existing houses. Promote universities and vocational colleges to update and replace advanced teaching and scientific research equipment, and promote the iterative upgrading of equipment and information facilities in medical and health institutions and the upgrading of wards.

　　3. The field of industrial development

　　Support manufacturing enterprises to implement digital green transformation, and encourage green and low-carbon transformation and transformation of data centers into green and low-carbon intelligent computing centers. Promote the upgrading of ropeways, cable cars and large amusement equipment. Orderly implement the renewal of power generation, transmission and distribution equipment such as old wind power and photovoltaic power generation, promote the renewal of old agricultural machinery, and help reduce pollution and carbon.

　　For example, the Municipal Development and Reform Commission has just issued the "Implementation Plan on Further Strengthening Loan Interest Subsidies for Equipment Purchase and Renovation in Key Areas", which provides preferential interest rates and loan interest subsidies for equipment purchase and renovation projects in 42 sub-sectors in 9 major areas, including strategic emerging industries, cultural tourism and municipal infrastructure. Take Shijingshan Amusement Park equipment updating project as an example. The project plans to update and upgrade large-scale amusement equipment such as roller coasters that have reached the service life. After it is put into use, the safety level and tourist experience can be significantly improved. It is expected that the project will receive discount subsidies from the municipal government for fixed assets investment, which can alleviate the investment pressure of enterprises to a certain extent.

　　4. Trade-in of consumer goods

　　Carry out the trade-in of green smart home appliances. Support platform enterprises to innovate automobile trade-in business model and improve service experience. Encourage residents to renovate their old houses, kitchen and bathroom, local renovation of doors and windows, etc.

　　5. The field of recycling

　　Improve the recycling network of waste products and equipment, promote the circulation and trading of second-hand goods, promote the recycling and resource utilization of waste materials, and support the construction of a number of green sorting centers for renewable resources.

　　For example, Huairou District is promoting the construction of a green sorting center for renewable resources, with an annual capacity of 200,000 tons for recycling and sorting waste glass, waste plastics, waste household appliances, waste textiles, waste foam and waste metal. The Beijing Municipal Development and Reform Commission is working with the Municipal Urban Management Committee and other relevant departments to study the support policies for such projects in combination with the Action Plan.

　　safeguard measure

　　This paper puts forward three safeguard measures: strengthening standard traction, strengthening innovation support, perfecting and implementing tax and financial policies.

　　news briefing

　　Xinhua News Agency: What specific support policies does Beijing have for equipment renewal?

　　What comes next is what remains: the equipment renewal work adheres to the principle of voluntary participation of enterprises, mainly giving full play to the main role of enterprises, and at the same time giving full play to the role of the government, implementing various central support policies, making overall use of government funds at all levels, increasing fiscal, taxation, finance, investment and other policy support, strengthening the organic connection of various support policies, and jointly providing more accurate and powerful financial support for enterprise equipment renewal. In the process of drafting the Action Plan, we also carried out research on relevant support policies, and at present, we have issued some support policies for equipment renewal. For example, the "Implementation Plan on Further Strengthening Loan Discount for Equipment Purchase and Renovation in Key Areas" issued by our Committee is well connected with the "Action Plan", and the municipal government’s fixed assets investment is arranged to give a discount of 2.5 percentage points to qualified equipment renovation and renovation projects in key areas for a period of two years. The equipment renovation project in Shijingshan Amusement Park mentioned just now enjoys this policy. For another example, on April 27, Zhongguancun Forum released "Several Measures on Accelerating the Development of General Artificial Intelligence Industry", proposing a green and low-carbon intelligent computing center with an intelligent computing power scale of more than 1,000 p, and the municipal government’s fixed assets investment will be supported by up to 50 million yuan.

　　What is released today is a general plan for equipment renewal. In the next step, relevant professional departments will study and formulate special support policies according to different characteristics in various fields.

　　Equipment renewal and trade-in of consumer goods is a long-term work, involving many industrial fields. As an overall plan, the relevant departments will speed up the introduction of special implementation plans in various fields, and all districts will also improve relevant working mechanisms and actively promote implementation. In the next step, the Beijing Municipal Development and Reform Commission will establish a special working mechanism with relevant departments, carry out the evaluation of implementation effect in a timely manner, continuously optimize and improve relevant policies and measures, and solidly promote the implementation of the Action Plan.

　　During this time, "live broadcast" is widely sought after among young people. Click on the live broadcast software and look at the men and women at the top of the rankings, only to find that they all look somewhat similar. No wonder netizens invented a new word to describe such deja vu — — "Net red face".

　　It’s not just live. Some people say that the beautiful territory is shrinking. For example, all kinds of retouching software make flawless skin a standard, but also face-lifting and long legs; For another example, thinness has become the only standard of figure, and some websites have even appeared "vomiting groups", and grotesque slimming methods have emerged one after another. Not only the appearance and face value, but also the pursuit of "small freshness" in taking pictures, and all kinds of routines are similar; Clothing is fashion-oriented, and cropped trousers are popular, so I wish everyone could swim without pulling their trousers. All these things always make people feel that they are missing a little bit of jagged polymorphism and a little less colorful.

　　It should be noted that beauty, to a great extent, is a social habit and cultural psychology. Under the commercial tide, the beauty of standardization is suitable for "mass production" and can bring greater input-output ratio. "The king of Chu has a thin waist, and many people starve to death in the palace." If the king of Chu is well dressed in purple, it will be difficult to see other colors in the palace. Similarly, advertisements, fashions and stars have shaped the contemporary understanding of beauty and also narrowed it down. As a result, "being fat and thin" is no longer synonymous with beauty, but has become the opposition between beauty and ugliness.

　　What you like is freedom for an individual. However, within the social scope, the simplification of beauty is prone to some problems. Lack of awareness of the beauty of diversity, aesthetics has become an "exclusive" activity, and it is inevitable that there will be "face value discrimination." Accompanied by it, it is "face value anxiety", which eventually leads people to go further and further on the road of misunderstanding beauty and go south in the process of obtaining beauty. What’s more, in our era, "face value" is really "value", which is linked to interests and can be realized.

　　Some time ago, a Chinese girl was elected as Miss Michigan in the United States, because she was neither awl-faced nor "delicate" and did not meet the "standard beauty" in the eyes of orientals, which attracted many netizens from China to vomit. But in fact, the healthy complexion, cheerful smile, confident manner and even risorius and big face all make this girl attractive. What’s more, social participation, manners and hobbies are her plus points. In fact, there is no distinction between beauty and beauty, and there is no solidification model. More healthy faces, diversified aesthetics and individual expression should remain in our aesthetic culture.

　　There is never a lack of diversified beauty in the world, but there is always a lack of eyes to find beauty and hearts to accept beauty. We can’t help but say what a wonderful world we will miss when our interests are defined by advertisements, blockbusters, stars and online celebrity. You may miss the healthy and charming ancient Greece, or the elegant and prosperous Tang Dynasty. More importantly, you may miss those people around you who are smart and capable, gentle and generous, knowledgeable and tasteful, or have temperament and vitality. Learning to appreciate the beauty of diversity will broaden your horizons and make your life more colorful.

　　For the shaping of life, it is also advisable to hold a diversified attitude. To some extent, we are easily influenced by the opinions provided by the media and advertisements. We define happiness as luxury houses and luxury cars, and regard the pursuit of wealth and power as the only definition of success. This, like a single aesthetic, fetters our colorful life and even gives birth to anxiety about success and happiness. Accustomed to walk along the track prescribed by others, the dense Yuan Ye outside the track, the blue sky overhead, and even countless wonderful possibilities can only pass you by.

　　Both the understanding of beauty and the understanding of life should be "from the heart". Looking at the sky through the narrow wellhead, there is only a corner of the world, but if we look at everything with an open and inclusive heart, the world will return the favor and return the gorgeous rainbow.

Baidu antigen-antibody structure prediction model is far more effective than AlphaFold3.

According to Baidu AI, in the research and development of antibody drugs and polypeptide drugs, the prediction of antigen-antibody and polypeptide protein complex structure plays a vital guiding role, and its accuracy is very important for subsequent research. However, from the current calculation methods, whether it is the energy function tool based on physical method or the method based on deep neural network, including the recently updated AlphaFold 3 of DeepMind, there is still much room for improvement in the structural prediction accuracy of antigen-antibody and protein-polypeptide complexes.

　　　　　　 CCTV News:The reporter learned from the press conference held by the National Health and Wellness Committee yesterday that more than 3,000 hospitals in China have piloted the construction of health promotion hospitals, and the focus of their work has shifted from "treating diseases as the center" to "taking health as the center".

　　　　　　 The first batch of health promotion demonstration hospitals, Hebei Handan Central Hospital, took the lead in setting up a smoking cessation clinic, set up 55 health knowledge propaganda groups, and went deep into enterprises, institutions and fields to preach health knowledge for nearly 300 times. In the physical fitness monitoring center, health managers guide people to lose weight scientifically.

　　　　　　 Zhang Xueqiang, Dean of Handan Central Hospital:Since June this year, our hospital has taken the lead in launching a scientific research project on weight management and a non-drug intervention weight management plan, and a professional dietitian has formulated a diet plan.

　　　　　　 In order to realize early detection and treatment of diseases, Sheyang County, Jiangsu Province organized 20 medical institutions and arranged 150 million yuan of special funds to carry out health checkups for 386,000 residents aged 19 to 64, and screened 17,000 patients with various diseases such as hypertension and heart disease.

　　　　　　 Wang Bing, Dean of Panwan Central Health Center in Sheyang County:The physical condition of this group of people is still relatively good. He has discovered this piece of disease early, and this awareness is not too strong. Through physical examination, we found that the incidence of chronic diseases such as hypertension and diabetes reached more than 35%.

　　　　　　 The National Health and Wellness Commission said that it will expand the pilot construction of health promotion hospitals, promote early diagnosis and treatment of chronic diseases, and strengthen the prevention and treatment of common diseases such as myopia and obesity among students. Promote the screening of chronic diseases such as cancer, stroke and coronary heart disease. Community health service institutions gradually provide services such as blood sugar and blood lipid testing and oral preventive health care. Basically achieve full coverage of management of patients with hypertension and diabetes. By 2020, we will strive to reduce the premature mortality rate of people aged 30-70 due to chronic diseases by 10% compared with 2015.

　　　　HiFi has always been a hot topic, and many mobile phones released recently are also focusing on HiFi sound quality: those using ES9318 DAC+ two-in-one audio chip, those using AKM HiFi chip and equipped with HUAWEI histen sound effects, and those supporting Bluetooth aptX & aptX HD HD music transmission, etc., all prove that mobile phone audio has always existed in an important position in the industry. So what is HiFi? What are the technical indicators of HiFi? What are the types of common mobile phone HiFi chips and what are their performances? You will know after reading this article.

Mobile phone HiFi, hi, no, hi. After reading these, you can be considered into the pit.

　　　　The full name of HiFi is High Fidelity, which literally translates as "high fidelity". To put it bluntly, it is a playback sound that is highly similar to the original sound. Spreading digital music on the network often needs to be suppressed, and there will be lossy and lossless compression. What we often see is that MP3 is a kind of lossy compression, which will affect the sound quality. Playing music is to convert digital signals into analog signals, and then amplify the analog signals and transmit them to headphones or speakers. HiFi is to make the final music close to the sound that the producer wants you to hear after production, that is, the sound quality is good.

　　　　Of course, sound quality and sense of hearing are not the same concept. The reason why audio is a metaphysics is that the sense of hearing varies from person to person, so there are "golden ears" and "fungus", and headphones or stereos of audio terminals will have different output performances because of various differences. At the same time, things like dolby pro logic and SRS sound effects all create distortion to improve the sense of hearing. The mobile phone HiFi we are talking about here is more about what kind of audio output the mobile phone as the output front end can have.

What are the common technical indicators of HiFi?

　　　　For audio veterans, mobile phones as the front end are often dismissive, because there is an irreparable hardware gap between mobile phone HiFi and professional audio, which the author will mention later. But for ordinary consumers, a carefully designed mobile phone with audio system is enough as a toy for getting started with audio.

　　　　I believe that there are not a few users who listen to songs on their mobile phones, but not many people know about HiFi. Moreover, when they go to see professional audio evaluation, there are many technical indicators that they can’t understand, but those who know audio are unwilling to explain more. The common technical indicators of sound system are: frequency response, signal-to-noise ratio, dynamic range, distortion, transient, stereo separation, stereo balance, audio sampling and so on. Here the author explains it separately.

　　　　frequency response: The frequency range of audio equipment during playback and the relationship between signal amplitude and frequency (amplitude-frequency characteristics). The unit of amplitude is dB, and the unit of frequency is Hz. The frequency response of the sound system should reach at least 32-18000Hz, and the signal amplitude change should be less than 2dB within this frequency range.

　　　　SNR: Logarithm of the ratio of useful signal to noise at the same reference point. At the input point of the speaker, the signal-to-noise ratio is 70dB, and the noise of one meter away from the speaker is almost inaudible, and the HiFi system generally reaches above 110dB.

　　　　dynamic range: Logarithm of the ratio of the maximum undistorted output power of audio equipment to the static system noise output power. HiFi system generally reaches more than 100dB.

　　　　degree of distortion: The degree of distortion of sound source signal when audio equipment plays back. The distortion of audio power amplifier can be divided into two categories: electrical distortion and acoustic distortion. The electrical distortion is caused by the circuit, and the acoustic distortion is caused by the speaker of the sound reproduction device. The types of electrical distortion are harmonic distortion, intermodulation distortion and transient distortion. Acoustic distortion is mainly AC interface distortion. The harmonic distortion of HiFi system is generally less than 1%.

　　　　stereo isolation: the separation degree of the left and right channels. Reflect the crosstalk degree of the left and right channels.

　　　　Stereo balance: The difference between the signal gains of the left and right channels.

　　　　transient stateRefers to those short and explosive sounds in music (especially percussion), which are usually difficult to reproduce accurately. Represents a physical quantity or phenomenon that changes between two adjacent stable States, and its change time is less than the time scale of concern.

　　　　Audio samplingDigital audio system reproduces the original sound by converting the sound wave into a series of binary data. The equipment used to realize this step is analog/digital (A/D), which samples the sound wave at the rate of tens of thousands of times per second, and each sampling records the state of the original analog sound wave at a certain moment, which is called a sample. A string of samples can be connected to describe a sound wave, and the number of samples per second is called sampling frequency or yield, and the unit is HZ (hertz). The higher the sampling frequency, the higher the acoustic frequency can be described.

Some audio chip parameters (picture quoted from love machine)

　　　　Signal-to-noise ratio, stereo separation and stereo balance can be distinguished by human ears, and other indicators need to be compared by multi-system comparison. Knowing this, it is not so difficult to understand when we look at the technical parameters of those mobile phone audio chips.

What are the common evaluation elements of HiFi we are talking about?

　　　　When watching audio evaluation, it is often confusing for beginners, because they don’t know what those evaluation elements mean. Although it is only a piece of music, there are many doorways. So here, the author selects three common evaluation factors to explain: sound resolution, frequency band and sound stage.

Sound resolving power

　　　　Analytic power intuitively means the clarity of sound and the expressive ability of detailed information. For example, this is like the resolution of a display screen. The higher the resolution, the clearer the picture, and the same is true for audio equipment. However, there is no clear quantitative index to measure it, so we can only rely on the human ear for subjective evaluation.

The higher the resolution, the more details we can "see" (picture from bilibili)

　　　　The analytical power of equipment has a comprehensive influence on human ears, including the cleanliness of the sound floor, the performance of overtones, the saturation of timbre, the clarity of sound image form, the texture of sound, etc. Simply put, it is "the ability to analyze musical details without losing information". HiFi is mostly exposed to the analytical power of earphone units. The resolving power of earphone unit is mainly related to the material, thickness and coil technology of diaphragm, which requires high technology and is a large part of the investment in R&D by manufacturers, thus directly determining the R&D and production cost of the unit.

　　　　In addition to the clarity of sound and the amount of detailed information, the benefits brought by high resolution are obvious separation of human voices and musical instruments. The so-called degree of separation is the layering of music. The better the layering, the easier it is for us to distinguish between human voices and background music, and the voices with low degree of separation will be mixed with instrumental sounds.

　　　　Of course, the degree of separation can be adjusted to a certain extent, such as reducing low frequencies and highlighting middle and high frequencies, so that the details will be clear, but the problem is that the amount of information in low frequencies is reduced, and then the music will appear thin.

　　　　But too high resolution will also bring problems, that is, distortion. Generally, earphones with higher price will have higher resolution, but the resolution will be seriously distorted simply by improving the sensitivity of the unit diaphragm to current, so the resolution of low-resistance earphones will not be set too high, because the front-end (power amplifier circuit) has limited control power, and strong resolution will bring greater dynamic distortion, which is why high-end earphones are mostly high impedance.

Sennheiser HD650 with 300 ohm impedance

　　　　However, the portable mobile phone HiFi has the problem of insufficient thrust. The larger the impedance, the smaller the sensitivity, and the harder it is to push the earphone. Therefore, it is not a wise choice to buy high-impedance high-end headphones only by looking at the price. The most serious consequence of insufficient thrust is that the music is poor in dynamics, and all the detailed sounds heard at the same time will be displayed in one plane, with no ups and downs in sound, no contrast in vocal instruments, lack of emotion, and the image is just like boiled water, which is seriously distorted. In a high resolution system, besides the unit quality, the control ability of the front-end system is particularly important.

frequency band

　　　　The so-called capacity distribution of high, medium and low frequency bands refers to the quantity of each frequency band within the frequency range that the equipment can emit. Some equipment has more high-frequency bands, some have a strong sense of low frequency, and some middle-frequency bands are particularly full of voices, but the amount of high and low segments is not so much.

　　　　The requirements of high frequency for each kind of listening and everyone’s listening habits are different. For music, it is not sharp to go up to the frequency band reached by music itself, that is to say, it can be said to be excellent if it is not stuffy and lubricated; It is very difficult to connect the intermediate frequency with the high frequency and low frequency. Almost all earphones can’t perfectly interpret the thick bass and thin soprano, and at the same time perfectly interpret the characteristics of each musical instrument. Low frequency is the most difficult frequency band to do, and it is not easy to do well in dive, elasticity and overtone during playback, so high-end headphones and earplugs are all working hard in this respect.

　　　　There is no absolute difference between the quantity sense of each frequency band and the quality sense. What is important is to achieve a balance after the overall collocation. The control of each frequency band tests the ability of audio equipment, such as whether the low frequency is loose or tight, whether the high frequency is lubricated or sharp, and so on.

Sound stage

　　　　Sound stage is the range in which the sound emitted by two speakers can be condensed and formed. Usually, if the two speakers are properly positioned (including the distance from the back wall and side wall, the height of the speakers and the angle of tilting inward, etc.), a concrete sound stage will emerge. You can even "see" the positions and distances of various vocal instruments and voices behind the speakers. To put it bluntly, it is an immersive listening experience.

Sound stage’s feelings have a lot to do with the sound layout (picture quoted from Baidu Encyclopedia)

　　　　Theoretically speaking, the reason why human ears can feel the sound field is because of the loudness difference and time difference between the left and right ears. The louder the sound channel is, the closer it is to the human ear. The loudness difference between the left and right ears enables the human ear to identify the sound source. At the same time, the delay of sound (residual sound) further enhances the three-dimensional sense of sound.

　　　　But it is not easy to form a good sound stage. Because the human ear is sensitive to different frequencies, not all frequencies can distinguish the distance and orientation, and about 7kHz is the most sensitive, while the extremely high frequency and extremely low frequency sounds have no directivity or very weak directivity. Relatively speaking, low-frequency directivity is worse, and low-frequency delay is a key quality for field experience.

　　　　In addition to the field sense of sound range (width and depth), the image cohesion is also a major index to evaluate sound stage. The shape, three-dimensional degree and sense of distance of the sound are the concrete manifestations of the cohesive force. The image is to see the performance site through the sense of hearing. Different musical instruments or vocals have different positions, sizes and characteristics. What is included in the fundus is a collection of all musical instruments and vocals, but they exist alone. You can see the individual characteristics of each of them or musical instruments.

Sound stage’s excellent knot is like being at a concert (picture quoted from Southern Metropolis Daily)

　　　　The requirement of image-forming power on audio system is relatively high, which is not only related to the hardware quality and sound quality adjustment of the front end, but also the image-forming power displayed by different headphones is very different. High-performance equipment combined with optimized adjustment can show excellent presence, but for HiFi, which is only an additional function, it is a very severe test, whether from hardware support or adjustment.

　　　　Of course, in addition to these three common evaluation indicators, there are many directions for evaluating audio, such as the proportion of musical instruments and the overall balance, but after understanding the above three evaluation factors, we can understand most of the audio evaluation.

What are the code names of HiFi? What are the reasons that restrict mobile phone HiFi?

HiFi system of Xiaomi Note

　　　　When we look at manufacturers’ promotion of HiFi selling points, there are always words such as DAC, ADC and operational amplifier. But for audio white, it is often confused. Here’s a brief introduction to common terms and expressions: ADC, SRC, DAC, and operational amplifier.

　　　　ADC stands for analog-to-digital signal coding chip.This device is rare in the promotion of mobile phone HiFi, and it is mainly used for audio input.

　　　　The sampling rate of CD is 16bit, 44.1K, and there are other sampling rates such as 48k, 96K and 192K. However, in the later processing, only one type can be processed, so a conversion is needed, and this conversion process is called SRC.This process can easily deteriorate the sound quality. Need special attention, this is a key point for smart phones to do HIFI. Such transcoding chips (such as CS8422) are expensive. At this time, an independent dual-clock crystal oscillator appears, which perfectly solves this problem: one corresponds to 44.1K, the other corresponds to 48K and its integer multiples, and what crystal oscillator is used for music in any format, which solves the SRC problem at low cost.

ES9018K2M　DAC

　　　　DAC is a relatively common component, representing a digital-to-analog signal decoding chip, and is a device for converting digital format audio files stored in mobile phones into analog signals.This is the independent audio chip that most mobile phone manufacturers promote, such as ES9018 K2M of Meizu PRO6 Plus. The quality of DAC often represents some quality parameters of the front end, such as dynamic range, signal-to-noise ratio, distortion and so on.

"539Y5P" is the AD45257 operational amplifier chip.

　　　　DAC completes analog signal conversion, but the output analog signal is very weak, and then the operational amplifier starts to operate.The full name of operational amplifier is operational amplifier. In the field of multimedia speakers, the operational amplifier chip is mainly responsible for the adjustment of volume, tone and peripheral effects., for example, integrated operational amplifiers are used in the front stage of audio and headphone amplifiers (amplifiers). For example, the common OPA1612 and OPA2604 are operational amplifier chips, and multiple operational amplifier chips can be integrated in one amp.

　　　　At present, most of the audio chips used in HiFi mobile phones on the market come from AKM and ESS. Here are some typical examples:

AK4490EN chip

　　　　AK4490EN is an ideal audio chip for mobile devices, which supports 32-bit/768 kHz source code output and high-specification 11.2MHz DSD files. Represents action.

ES9018K2M chip

　　　　The ES9018K2M chip has a dynamic range of 127dB, which can fully display the details of music. The ultra-low distortion of -120dB THD+N can better restore the essence of music.

　　　　Equipped with ES9038Q2M and three OPA1622 operational amplifiers, it has a dynamic range of 129dB and a distortion of -120dB, and supports DSD hardware decoding.

ACS43L36 decoding and ear amplifier integrated chip

　　　　Of course, in addition to these two chips, CirrusLogic decoding and amp integrated chip CS43L36 has also appeared on Meizu’s PRO 6, and basically all the audio parts involved in PRO 6 are controlled by it.

　　　　Although HiFi mobile phone is equipped with professional audio chip, it has a certain gap with high-quality walkman in terms of resolution, dynamic response and thrust. The reason is that the power supply scale, decoding chip specifications and the number of operational amplifiers are not as good as the latter. For example, the ES9018K2M mentioned just now is actually a scaled-down version of ES9018, which is a low-power version specially customized for mobile devices. The former is dual-channel and the latter is 8-channel. Whether it is dynamic range or signal-to-noise ratio, ES9018 is far better than ES9018K2M. The main reason why enthusiasts don’t want to use mobile phones to listen to high-quality headphones is because of the thrust of mobile phones on headphones, and they can’t give full play to good headphones.

In which direction will HiFi develop?

　　　　At present, limited by the circuit structure and power supply of mobile phones, there is still a long way to go to equalize the sound quality of professional equipment. Of course, we do not rule out the possibility of improving the battery technology of mobile phones, further optimizing the circuit design, and further controlling the heat and power consumption by high-quality audio chips, but it will be difficult to achieve it for a while.

It is also beneficial to integrate the decoding operational amplifier into the earphone.

　　　　In addition, mobile phones are gradually developing towards thinness, and the contradiction between battery capacity and chip power consumption is increasingly prominent, and there are signs of canceling the 3.5mm headphone jack in a large area. The most typical is the series of mobile phones. The 3.5mm earphone interface is cancelled, and the Lightning data interface can only output digital signals, and the decoding and operational amplifier will be integrated into the earphone. Although the high-end audio circuit can be used without signal interference compared with mobile phones to further reduce the noise floor, the power consumption of headphones is serious, and the high-integration decoding and operational amplifier will damage the sound quality output to some extent, and unreasonable circuit design will also produce certain noise floor.

Active noise reduction principle

　　　　Fortunately, there are still many remedies for mobile phone HiFi. For example, better audio technology is adopted at the earphone end. For example, 1MORE’s Tiinlab A2 exclusive active noise reduction chip can adjust the frequency band for noise reduction with broadband EQ as a supplement, and at the same time, it has a very good adaptability, such as Lightning and USB Type C digital interface. Thanks to the self-planned Tiinlab A2 exclusive active noise reduction chip, 1MORE full-time noise reduction technology achieves a perfect balance between noise reduction effect and sound quality. Tiinlab A2 is in the range of 50-2000Hz, which has covered most business and life frequency bands, which is wider than the frequency band where most noise-reducing headphones are only concentrated within 1000Hz, but at the same time, the noise reduction depth is controlled, and the inhalation feeling will not be too strong.

　Intelligent sonar earphone

　　　　Another interesting thing is HTC’s HTC USonic smart sonar headset. This earphone uses sonar to sense the cochlear structure, feeds back the signal to the mobile phone, makes custom adjustment according to the specific shape of each ear, and then outputs lossless timbre through USB-C interface, providing a good audio experience.

MDR-XB950BT Bluetooth Headset

　　　　At the beginning of this article, we mentioned that one plus five supports aptX & aptX HD HD music transmission. Undoubtedly, wireless Bluetooth will also be one of the solutions for future mobile phone HiFi. At present, the main quality standards of Bluetooth audio coding are SBC, AAC, aptX and LDAC from low to high. SBC has the best compatibility and the worst sound quality. AAC is relatively better. If the mobile phone plays AAC audio files, then using AAC Bluetooth coding transmission can save a coding conversion step, and the sound quality is more fidelity, but the gap is not small. AptX is a higher Bluetooth audio coding, and aptX-HD can achieve near lossless sound quality. LDAC is a Bluetooth audio coding promoted by Sony, which can achieve -Res lossless audio transmission and has the best sound quality. However, apart from Sony’s own equipment, there are not many supporting this coding at present, but it is the future development direction.

Write it at the end

　　　　After reading the above contents, I believe everyone has a certain understanding of audio and mobile phone HiFi. Although these are only nine Niu Yi hairs in the audio industry, after understanding these, we can roughly understand what level of mobile phone HiFi is promoted by mobile phone manufacturers, and we can also have some basic knowledge support when choosing headphones. Of course, it should be kept in mind that even when purchasing headphones for HiFi mobile phones, you can’t just look at the price. After all, the thrust of mobile phones is limited, and different headphones have different styles. The right combination of front and rear ends is the best choice.
