Hello Everybody, welcome to watch this program
In the rise of the digital age, Sound technology is changing things like never before, reshape our life. The digital mems sound chip, is one of the key drivers for change it combines electromechanical and computing technologies, sound generation and processing push to a new level. Not only in extremely small sizes, achieves superior sound quality, it can be widely used in various devices.
Todays guest in the studio, provides a richer, more immersive sound experience. She has important results to share. Lets first learnt about it via a short video:
Video
Du Haijiang, Chairman of Earth Mountain Technology, company focusing on chip design, tech, enterprises in R & D and manufacturing. Through innovative technology platforms, gradually subvert traditional loud speakers produce sound, its digital mems sound chip, using memes plus digital audio algorithm technology, pixelate sound waves through semiconductor processes, achieve digitalisation at the sound end compared to traditional moving paper cone technology, breaking through the traditional sound production principal. Takes audio quality to a whole new level. Earth mountain has been working with Audio Pixels since 2018 and continuously improve its R&D and innovation capabilities comma signal processing in mems structure manufacturing process, audio algorithms and packaging. Etc All have innovative breakthroughs
back to the interview
Commentator
Coming to the studio today is Earth Mountain’s Chairman Du Haijiang, Miss Du introduce it to us first – is what you do – mems design, R & D and Manufacturing – What kind of system is it
DH
This is a mems microelectromechanical system, in fact the system is actually proposed in the US in 1967. Its through the semiconductor process then implement some micro electro mechanical systems
C
what is it used for
DH it is widely used in many sensor fields, for example a pressure sensor, infrared sensor, used in blood pressure sensor. There is also a lot of traffic used in industry, and the radio frequency they do. This process is actually used in various fields. Our mems speaker is the speaker. It happens that mems technology is also usedto realise it.
C
I still cant imagine it. its about the scenarios its used in.
DH
For example artificial intelligence sensing systems. In fact many of them need to be miniaturized. IN fact they are all made using MEMS technology. This technology is used for processing. But it is used in many fields. For example the medical field. There is also the mechanical field. Also fields like sensors. They use a lot of this kind of technology
C
Whats the difficulty with this technology
Dh
Our chip, in fact the most important problem to solve is, its digitalization, usually a speaker, to achieve full spectrum, it takes a lot of combinations to achieve, because it is simulated non linear, but our technology, processed through processes such as mems, we can achieve digitalization, digital concept, that is it is linear and easy to control
C
I understand. I probably have made it clear. Probably understand. Then I will know after I understand. This is it. Actually this last one is very difficult, very difficult. This technology. Did you learn from others or make your own breakthrough
DH
So this matter is actually, there is also a lot of help from people in the industry> for example DR Zhang Rujing. So in this project gave us a lot of strong support. Its like saying its on someone's shoulders. We made a sublimation. Only when we can stand on peoples shoulders can we stand higher
C
So if we have this after this technology you just mentioned. What are the next development prospects
Dh
We hope that this new technology, after breaking through the process, after mass production is possible, then on this basis we, the original design of this chip, in fact we have it, in fact what we can achieve is, after I digitize, there are so many innovations. For example if I talk to you, I don’t want them to hear (and she is pointing in another direction). There has never been a technical implementation before. There is no way we can integrate traditional speakers. Because the instantaneous response sign of traditional speakers. There is none as it is non linear and difficult to control. But after digitalization it will be easy to control. I let is sound all towards a spectrum. Make this spectrum very strong, so I just want you to hear (pointing at the commentator). Try not to hear by others. Many, many innovations have come out
C
to some extent, it is also like our electric car. What we are facing now is also the same. Just the past. For example, take this fuel vehicle. All have been taken over by these giants. The research is over. There is no space for you. And now there is an electric car. This is flat land. Everyone goes in at the same time
Dh
Because traditional engine technology. Not in your fragrance. But using an engine of an electric car. No need for this technology anymore
C
Right
DH
There is no need to restrict me with your patents
C
What can we do now
DH
We are probably at the stage of production. A breakthrough is coming soon. We can do it in mass production. Because what are the characteristics of semi conductors? That is to say if you look at the semiconductor industry, only the eldest and the second child. There are very few thirds, did you find it. Because of the large scale of semi conductors, as long as you produce it in batches, then after measuring it, others cant compete with you at that cost, you did it first, therefore your cost is solved in large quantities, you can produce it in large quantities after being introduced into the market, the market is big enough, others cant compete
C
I still have this problem, that is if you open up the front, it’s the back, how should it be followed up to others form, just like we are with , smart car or electric car. This advantage formed
DH
In fact we want to do it for the TOB (enterprise). For example like a car, electric car vehicles now, its main features are entertainment, for example in am in a car, I can enjoy all kinds of things I like, whether it is music, tv series or music, or the affect of a live concert but for now, it is the current tech that makes it difficult to realise but with our technology it is very easy to realise. Lets make panoramic sound come to the whole sound field of the parking lot because of digitalisation, including AI algorithms to arrange, very fast, very easy.
So in the future our technology will come out, if it is with our domestic car, if you want to match, then I think our car is competitive. Another step has been added
C
What else can this be applied to
DH
The field of all loud speakers, like our current mobile phones, in fact you are very few will listen to the mobile phone in an external setting, because it is bad and there is no low frequency, including home audio don’t need such a heavy loudspeaker anymore, you can put it into the material like a hearing aid. The same is true, we can make this smaller
What are the benefits of hearing aids. Lets just say it’s a simulation now, its difficult for you to adjust, if you want to use them it enlarges all sounds currently, because the current simulation cant be controlled. So I often scare the elderly. I was shocked when I put on the hearing aid. It cant be adjusted so accurately.
C
You have been at this for a while but this could be like internet+?
In fact you guys, it can become a plus sign in the future. There is just a lot of room for imagination
DH
Its equivalent to a revolution in sound. Standards will also change, like our current Dolby. In fact dolby is an integrator. It combines 3 properties of sound. Maximising current performance, for example 7 channel or 5 channel, what stereo sound is doing? But now we have reached this stage of sound it is difficult to achieve. After our chip comes out, new standards will be released. We will set a lot of sound standards
C
The we have to hurry up
DH
I have to hurry up but it is just not easy. Fortunately we have a team like Dr Zhang, helping us like a charity
Then it goes to a video of a mems manufacturing machine and says – Digital mems manufacturing (at 8minute mark)
Open a new ear of acoustic sound. It represents the tradition sound industry, a huge breakthrough in microphones, will be used for audio and acoustic applications
C
This is the main purpose for coming on this show
DH
She agrees with the commentator. Let everyone know about this tech. everyone wants this tech, then everyone can contribute, then make it a success. In fact this tech, will it remain in this country in the end. Actually I don’t really care. I think it would be really good if I could stay in our country
C
Come on, I also hope more of us are able to realise such an opportunity exists, ok , good
DH
Thank you very much
