Chinese entertainment for engineering students

Out of practical considerations, Wang Xu took the cost into consideration when designing this kind of microphone. It wasn't that he didn't want to use expensive ones, but that some things weren't available yet, so he had to make do with them.

This leads to the fact that the cost of the entire circuit is not high, and may not be as expensive as the film capacitor in total.

In other words, the film capacitor for which Wang Xu does not yet know the specific price will be the main cost. But this is normal, after all, the main feature of condenser microphones is this capacitor.

Unfortunately, Wang Xu didn't know the price of purchasing that capacitor alone. Without the Internet, it was really inconvenient to collect all kinds of information.

But Wang Xu feels that the price of the final product should be within an acceptable range.

This makes Wang Xu's invention valuable because it has practical value for mass production.

Strictly speaking, this is the first product that Wang Xu has tinkered with that can be mass-produced.

However, the market for microphones is already very small. After all, the entertainment form of karaoke has not yet become popular.

As for this kind of professional-grade microphone, the market is probably even more limited. Maybe not a few of them will be sold across the country. Maybe they can be exported, but this is a matter of commercial operation, and Wang Xu has no experience in this area.

Yesterday, when Wang Xu took the two microphones to his mentor and told him that he had invented two new types of microphones, his mentor Luo Congwen felt messy in the wind.

Where is this? How can this student be so troublesome? I just sent him the paper a few days ago, and this is a new invention.

He is engaged in algorithm research, so he doesn't know anything about microphones. All he knows about microphones is probably the microphones used to speak at conferences.

Okay, let's continue taking Wang Xu to report, so Professor Yan Xueping, the deputy dean in charge of student affairs, was alarmed again.

At this time, there is no intellectual property management office in Shuimu. It was a department established in 2015. Even the State Intellectual Property Office is still called the National Patent Office.

Fortunately, as a big boss in the automation department, he was no stranger to applying for patents, but he was quite shocked when an undergraduate came to apply for a patent.

You know, in this era, most Chinese people don’t even know what patents are. After all, just last year, more than 10,000 patents were applied for across the country.

Readers may not be very sensitive to this number, but it will become clear if you compare it with the data from previous lives.

In 2022, the number of patent applications nationwide will be 1.2 million, nearly 100 times that in 1990.

And even in 2022, when popular science can be delivered to rural areas through various self-media, for most ordinary people, applying for a patent is still a legendary thing.

Even in the circle of ordinary people's friends, no one can be found who has even a patent signature.

With this comparison, you can see how rare it was to apply for a patent in that era.

Professor Yan personally called a patent lawyer who had been working with the department for a long time and asked him to come over for an interview about applying for a patent.

In the future, there will be many professional patent application agencies on the market. They can help you convert your results into protectable patent documents from beginning to end. This is not a legal matter, so there is no need for professional lawyers to handle it.

Shuimu even has its own intellectual property office to help unfamiliar people with patent applications and achievement transformation operations.

But in this prehistoric era, patents can block a large number of people just by writing documents. Too many people have invented things but have lost the patent rights due to lack of knowledge or skills.

Therefore, Wang Xu also discussed his views with Professor Yan and made suggestions to Professor Yan on some future functions of the Intellectual Property Management Office.

However, Professor Yan did not answer this question. This was not something that he, the deputy head of the department, could completely decide. But Wang Xu could tell that he was probably interested.

After that, Professor Yan brought the topic back to the invention itself and asked Wang Xu to ask questions to learn more about the use, principle and even the advantages of this new invention.

As a patent applied by a student, the student’s affiliation must be Shuimu University. Although this kind of purely private invention patent has no practical significance for the school, it can still be displayed in the teaching results.

After all, it is quite rare in this era for students to apply for patents, especially for a sophomore undergraduate.

If the school asked about the causes and consequences of this student's invention, it would be ridiculous for him, as the deputy head of the department, to know nothing.

However, when Professor Yan heard that Wang Xu said that the performance of this microphone was top-notch in the industry, Professor Yan became a little unable to sit still. He felt that this matter might be more important than he initially expected.

Whether it's papers or patents, although they are rare at Shuimu University, they are not unique. But in this era, in China, where everything is being pursued fiercely, there are really no products that can reach the top of the industry, except for some traditional handicrafts.

If there is really a top result in the industry, it will be a resounding achievement for Wang Xu personally, the Automation Department, and even Shuimu University itself.

Of course, Professor Yan still couldn't be completely sure. He didn't understand the audio equipment industry. But as a music enthusiast, he also knows a little bit about it. The Kenwood audio set at his home was brought back from RB when he returned to China, and he did a lot of fiddling with it.

This kind of music product is related to technology, but it is not completely related. There are many things that modern science has not yet understood.

Especially when mixed with human feelings, it becomes even more irrational.

Anyone can tell whether it sounds good or bad, but what sounds good cannot be defined physically at all.

This is troublesome. Basic parameters such as the finished product can be tested, such as frequency domain width and sensitivity. These can all be detected.

Although it requires the help of some professional equipment that Shuimu does not have, it can always be borrowed, for example, from the Institute of Acoustics of the Chinese Academy of Sciences.

But when it comes to the specific use experience, it is too difficult to deal with, because Wang Xu said that this thing is top-notch, which may just be Wang Xu's feelings. What other people think, and what professionals think, is a mystery now.

Without really testing it everywhere, I really can’t give a definite conclusion.

However, Professor Yan was inclined to believe in the beautiful male classmate in front of him. In the previous exchange, he could tell that this student was a professional in the fields of acoustics and electricity.

And although the papers and inventions at one moment may seem out of place, they have indeed produced results.

Professor Yan can understand the obviously handmade circuits used in the microphone in front of him, as well as the circuit that adjusts the sensitivity. It should be said that it is very delicate, which proves that this student is good.

Therefore, Professor Yan decided to believe him for once. He plans to apply for professional testing from the Institute of Acoustics of the Chinese Academy of Sciences for Wang Xu’s invention.

This will definitely require a favor, but that's not a problem. We are all neighbors, and it’s as if no one has asked anyone for help.
