Huayu for engineering students

Chapter 63 No.60 Three: Patents (seeking further reading, recommendation, monthly pass)

Out of practical considerations, Wang Xu considered the cost when designing this kind of microphone. It's not that he doesn't want to use expensive ones, but that some things don't exist yet, so he can only make simple ones.

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

In other words, the film capacitor whose specific price Wang Xu does not know will be the body of the cost.But this is also normal, after all, the main feature of the condenser microphone is this capacitor.

It's a pity that Wang Xu doesn't know the price of buying the capacitor alone. Without the Internet, it is really inconvenient to collect various information.

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

And this makes Wang Xu's invention more valuable, because it has practical value for mass production.

Strictly speaking, this is the first mass-produced product produced by Wang Xu.

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

As for this kind of professional-grade microphone, the market may be even more limited.It might not be possible to sell a few in the whole country, maybe it can be exported, but this is a matter of commercial operation, and Wang Xu has no experience in this field.

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

What is going on here? How can this student be so troublesome? He only sent the paper to him a few days ago. This is another new invention.

He is engaged in algorithm research, so he doesn't know what the hell microphone is. All he knows about microphones may be the microphones used for speeches at conferences.

Come on, continue to report with Wang Xu, so Professor Yan Xueping, the deputy dean in charge of student affairs, was alarmed again.

At the moment, there is no intellectual property management office in Shuimu, which was established in 2015. Even the State Intellectual Property Office is still called the State Patent Office.

Fortunately, as a senior in the Department of Automation, he is no stranger to applying for patents, but he was quite shocked when an undergraduate came to apply for a patent.

You know, in this day and age, most Chinese people don't even know what a patent is. After all, the country only applied for more than 1 patents last year.

This figure may not be very sensitive to readers, but it will be clear if compared with the data of previous lives.

In 2022, the number of 120 million patent applications nationwide is nearly 1990 times that of 100.

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

Even in the circle of friends of ordinary people, there is no one who has even a patent signature.

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

Professor Yan personally called a patent lawyer who had been cooperating with the department for a long time and asked him to come over to discuss patent application matters.

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

Even Mizuki has its own intellectual property office to help those who are not familiar with the operation of patent application and achievement transformation.

But in this prehistoric era, patent writing alone can kill a large number of people. Too many people invented things but were limited by lack of knowledge or skills and missed patent rights.

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

However, Professor Yan didn't answer the question. This is not something that a deputy department head like him can fully decide.But Wang Xu could tell that he should be caring.

Afterwards, Professor Yan brought the topic back to the invention itself, asked Wang Xu to ask questions, and learned about the use, principle and even the advantages of this new invention in detail.

As a student applying for a patent, the student's affiliation must be Mizuki University.Although this patent of purely private invention has no practical significance for the school, it can still be displayed in the teaching results.

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

In case the school asked about the cause and effect of this student invention, it would be ridiculous if he, as the deputy head of the department, knew nothing about it.

However, when Professor Yan heard that Wang Xu said that the performance of this microphone was top in the industry, Professor Yan couldn't sit still. He felt that the importance of this matter might be higher than his initial expectation.

Whether it is a paper or a patent, although it is rare at Mizuki University, it is not unique.But in this year and month, in China, where everything is being pursued, there are really no products that can reach the top of the industry, except for some traditional handicrafts.

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

Of course, Professor Yan is still not completely sure, he does not understand the audio equipment industry.But as a music enthusiast, he also knows a little bit about it. The Kenwood stereo in his home was brought back from RB when he returned to China, and he didn't make much trouble.

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

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

Whether it sounds good or bad, anyone can say a thing or two, but what is good sounds cannot be defined physically.

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

Although it is necessary to borrow some professional equipment that Mizuki does not have, it can be borrowed anyway, for example, the Institute of Acoustics of the Chinese Academy of Sciences.

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

It is really impossible to give a definite conclusion without actually making it and evaluating it everywhere.

However, Professor Yan tends to believe in this beautiful male student in front of him. In the communication just now, he can hear that this student is professional in the fields of acoustics and electricity.

And although it seems to be jumping off the paper for a while, and the invention for a while, it has indeed produced real results.

Professor Yan can understand the obvious hand-made circuit used in the microphone in front of him, as well as the circuit for adjusting the sensitivity. It should be said to be very delicate, which proves that this student is good.

Therefore, Professor Yan decided to trust him once.He planned to apply for a professional test from the Institute of Acoustics of the Chinese Academy of Sciences for Wang Xu's invention.

It's definitely a favor, but that's not the problem.They are all neighbors in the neighborhood, as if no one has begged anyone.
