Li Zhongxin has always had the idea that things should not be too advanced when making things. They should be in line with the development speed of today's society and should not directly make large leaps.

The development of the world! There are rules to follow. We must not develop in a hurry and go against the rules.

And something like MP3 was developed at this time! It is not a technological transcendence, but a so-called advancement.

Otherwise, Li Zhongxin would not have been committed to the development of the real economy and not put a lot of energy into high-tech products.

It's time now! Li Zhongxin feels that these scientific research bases are already relatively mature. If they want to make the scientific research base bigger and stronger, they cannot rely solely on Zhongxin Company for investment. They must also produce some corresponding results. Through these

The results have given Zhongxin Company some gains and allowed the experts and scholars in Zhongxin Research Base to see a broader future.

With the birth of many outstanding scientists, good results, and generous salaries and shares, to a certain extent, Zhongxin Scientific Research Base will have more scientific researchers join it, making Zhongxin Scientific Research Base

It will have a place in the future social development.

Among them, Li Zhongxin thinks that the most profitable thing is a small and exquisite thing like MP3. No one has recognized this thing yet, and no one is aware of it. So, at this time, he should let Zhongxin Research Base

Conduct research on these things and produce scientific research results as quickly as possible.

After the scientific research results are obtained, Zhongxin Company can become a manufacturer in this field, allowing MP3 to occupy the market as quickly as possible and become the first representative of Zhongxin Company in science and technology.

What kind of situation would it be best to have? That is, when people want to buy MP3s, the first thing that comes to mind is the brand of Zhongxin Company. So, if Zhongxin Company’s zx mobile phone is launched in the future, people will be interested in this

More trust.

Li Zhongxin still remembers a little story about MP3, that is, the birth of the world's first MP3 player.

In fact! No matter what new things happen, there are always surprises.

Li Zhongxin remembers that MP3 was the first thing to be developed in South Korea. At that time, it should be Moon, a department manager of Samsung in South Korea. This is the Korean spelling of the Korean surname. He was on the plane back to Seoul from a business trip in the United States.

On his laptop, he saw a report sent to him by a colleague.

This is a briefing composed of images, text and MP3 music. When Moon finished reading and took off his headphones, he found that the passenger next to him was listening to MD. Moon was immediately inspired.

He felt that if the MP3 music files on the computer could be directly taken out and played on an independent player, wouldn't that be the best music player?

After returning to South Korea, he proposed the idea to the president at the time. Unfortunately, Samsung was undergoing organizational reorganization at the time and had no time to consider Moon's development proposal. Half a year later, the Asian financial crisis caused a huge impact on Samsung.

Mr. Moon was also forced to retire early.

After leaving Samsung Corporation, Mr. Moon joined Saehan, a subsidiary of Samsung, as president, and turned his ideas into reality at Saehan, launching the world's first MP3 player - MPMan F10 in 1998.

.

In other words, MP3 was first launched in 1998. At this time, if the scientific researchers of Zhongxin Company work hard enough, it will take only one or two years at most to mature such a technology.

.

If such a technological maturity can be achieved, then the Zhongxin Research Base will be able to develop or research other things faster in the future.

And what’s more! In Li Zhongxin’s mind, an MP3 player is actually a small computer with specific functions.

In the small body of the MP3 player, there are MP3 player memory - memory card, MP3 player display - LCD display, MP3 player central processing unit MCU - microcontroller or MP3 player decoding DSP -

-Digital signal processors, etc., what about these things! According to a certain proportion or term, it is a micro computer.

It's just that this kind of miniature computer eliminates some parts of the computer and makes a series of simplifications.

The microprocessor is the brain of the player, used to accept the playback control selected by the user, display the currently playing song information on the LCD screen, and then issue instructions to the data signal processing chip to accurately process the audio signal.

The digital signal processor first uses a decompression algorithm to decompress the MP3 file, then uses a digital-to-analog converter to convert the digital information into waveform information, and then the amplifier amplifies the signal and sends it to the audio port. Finally, we can use the headphones connected to the audio port

I heard beautiful music.

At the same time, we can use its built-in data cable (USB) to connect to the computer and import our favorite audio files into MP3 through the network. Not only can we listen to music, but we can also perform necessary English listening training.

What about these things! Li Zhongxin has done some research on this kind of thing, because in later generations, Li Zhongxin was considered an MP3 enthusiast. After MP3 appeared, he liked it very much, and he even did some research on such a thing. At that time,

What Li Zhongxin was thinking was that this thing was so miraculous that he simply didn't understand how such a small thing could have such powerful functions.

Li Zhongxin clearly knows that the most important thing about MP3 is the storage and decoding chip. Manufacturers usually do not disclose the information of storage chips. Of course, the quality of chips from major manufacturers such as Samsung, Intel, and Toshiba is better.

The decoding chip not only determines the speed of audio processing, but also determines the special sound effects functions of MP3, including multiple EQ and 3D sound effects.

Of course, the decoding chip is also one of the most important parts that affects sound quality. The algorithm of the APU (Audio Processing Unit) will play a decisive role in the restoration of the waveform. Although the MP3 format is also lossy compression, it uses a high sampling rate

After that, the sound quality of MP3 will be greatly improved.

However, MP3 audio files with high sampling rates require decoding chips to support high data streams, and the decoding chips used in cheap products are obviously not capable at this time.

The products currently produced by Zhongxin Company are comparable to the current magnetic card chips, or some simple chips. It also has supply and sales business with many Chinese companies, but when it comes to making MP3 chips, it still feels a little weak.

Out of reach.

Li Zhongxin’s idea on this matter is very simple. First, we should get these things from Japan, and then let the people in Zhongxin Scientific Research Base who are responsible for this aspect to conduct research to see if Zhongxin Scientific Research Base and Zhongxin Wafer Factory can come up with something suitable.
