Chapter 62 Microphone (please read, recommend)

The sun is rising and the morning light is shining.

Wang Xu got up and started boxing, leaving Tang Yun's matter to be solved by herself, and Wang Xu became famous. However, Wang Fei was still jealous all night, saying that she was still there, so Wang Xu bought a maid.

In fact, Wang Fei was too tired the day before yesterday and couldn't do this every day. Wang Xu still hugged the girl and had a good sleep.

But this directly led to Wang Xu being very angry today. He got up before dawn and went to boxing.

As for the maid, I hope Guo Liang doesn't misunderstand.

Wang Xu had to go to the laboratory today, and for the next few days. This suddenly made him feel like he was about to go to work, a feeling of being a social animal, which he had not experienced in many years.

——

It only took Wang Jinghua two days to take up the post, and then took over the decoration project of the courtyard.

Wang Xu asked the accountant to do the accounting, distributed a bonus to Wang Chao's clothing, gave Tang Yun 20,000 yuan, and asked her to redeem herself, thus settling the matter.

I took 180,000 yuan and invested it in Wang Chao Art Studio.

In fact, the money was mainly earned in the first week, and only tens of thousands in the next two weeks. However, it is obvious that Wang Chao Clothing is no longer worried about survival issues.

The waiters that the labor center helped find, as well as the accountants and cashiers have all taken up their posts, and they are full-time. The waiters have gone to Wang Chao Clothing and are under the management of Tang Yun.

The accountant and cashier are all under Wang Jinghua, and they are also responsible for the cash flow of Wang Chao Clothing. There is not much work at present. In the future, Wang Chao Studio will be changed to the parent company of Wang Chao Clothing and hold all the shares.

Wang Chao Studio was opened by Wang Xu and Wang Fei 73%, and Wang Fei's 30% shareholding was held by Wang Xu on behalf of Wang Xu. Wang Xu had to persuade Wang Fei to agree to 30% of the shares.

This girl has no interest in business at all, and doesn't even bother to ask for any shares. She just wants to guarantee her clothes every month.

Tang Yun took 10% of Wang Chao Clothing's shares as an incentive. This had been agreed upon a long time ago, and Wang Xu did not intend to make any changes.

Due to the addition of Wang Chao Clothing, a subsidiary with a large cash flow, Wang Jinghua's dry shares were reduced to 5% of the studio, which is also a 10-year option. Her current position is the general manager of the art studio.

It was not popular to be called CXO at this time. Manager was the standard title at this time. Wang Xu did not stand out and just followed the trend to save trouble.

In the blink of an eye, a few days later, Wang Xu returned to the small courtyard with the adjusted recording equipment. Unfortunately, the small building was not decorated yet, so he had to put it in the warehouse first.

Recording studios require special soundproof walls and sound-absorbing walls. Even if they are installed in an ordinary room, they will be tortured by the echo.

The rented laboratory was of great help to Wang Xu. In addition to debugging recording equipment, Wang Xu also successfully made several sets of microphones.

The base is from RB Audio-Technica, a product made a few years ago that was quite expensive, but these ones got damaged due to moisture and no one knew how to repair them, so Wang Xu took them back with scrap prices.

Wang Xu does not have the kind of film capacitors provided by the system, but the circuit ideas given can still be used as a reference. The quality of the existing films is very good, and they are also high-end products in the world, but there are some problems with Audio-Technica's circuit design.

This is a system engineering problem, and everyone knows the solution. However, the final products produced by different companies will still be different, and every product of each company has various problems, big or small.

.

For users, different microphones may produce different sound characteristics. If used properly, a less expensive microphone may be more effective.

As a result, certain product defects eventually became the characteristics of certain brands, forming distinctions such as a certain tone being cooler and a certain tone being warmer.

This is very metaphysical, or at least very emotional. This is why the manufacturing of musical instruments and audio equipment does not always keep pace with the development of electronic technology, and is always half a beat, or even a few beats slow.

But generally speaking, the pursuit of high sensitivity and high fidelity is still the ultimate requirement for microphones.

A so-called good product is often one in which the capabilities of the components can be fully utilized and at the same time the components have the least negative impact on each other. For this kind of system tuning, Wang Xu’s good ears are the biggest plug-in.

He was able to keenly discern the subtle differences in sound waves reflected in the headphones when using different microphones. At this time, his ears were better than an oscilloscope.

Of course, since it is a system project, the capabilities of headphones and speakers as output devices limit the upper limit of Wang Xu's judgment.

So Wang Xu could only adjust the microphone, then go back to adjust the headphones, adjust the speakers, and then go back to adjust the microphone. In short, it was a lot of trouble.

Fortunately, the final result was unexpectedly good. Wang Xu successfully made a simplified version of the system microphone.

The effect of the finished product is very good. In Wang Xu's ears, it is at least much better than the Audio-Technica top.

Although he has never bought one, Wang Xuke has tried various input and output devices from equipment dealers, and he can speak clearly about the microphones, headphones and speakers available on the market.

The frequency response of this microphone that Wang Xu tinkered with is very wide, perfectly covering the complete limit of human hearing, achieving full coverage from 20hz to 20Khz.

However, in the ultra-low frequency and ultra-high frequency parts, there are obvious signs of attenuation. This should be a problem with the capacitor film. After all, Wang Xu used the original Audio-Technica's own film capacitors.

As for the lower and higher parts, Wang Xu didn't test them at all, because even he couldn't hear those sounds, which were in the category of infrasound and ultrasonic waves.

Moreover, the sensitivity of this microphone is quite high, especially for capturing weak breaths, showing amazing sensitivity. This sensitivity is the best in the industry.

But then again, Wang Xu made this kind of microphone too sensitive, and the requirements for singers were simply ridiculously high.

For a singer like Wang Xu who has very high breath control ability, such a microphone is simply an artifact. As for Wang Fei, there should be no problem.

Her breath control is now very stable. Although she lacks the ever-changing enchantment of later generations, her basic skills and foundation are already stronger than those of later generations. As for her unpredictable and ethereal voice and sexy and charming breath changes in the future, she will still be able to control her breath.

It takes years of accumulation to mature slowly.

But for ordinary people with karaoke skills, or even ordinary singers whose singing skills are not up to standard, using this kind of microphone may expose the shortcomings.

Any slight breath instability, or the sound of exhalation and inhalation, will be recorded clearly, instead of being blurred like an ordinary microphone.

Of course, such a sound can also be adjusted through the skills of a tuner, but this will increase the difficulty invisibly, and will also lead to a surge in costs.

To this end, Wang Xu has specially designed a set of special circuits that can fine-tune the sensitivity and create an adjustable microphone to provide a better choice for singers with average singing skills.
