Chapter 725： Shaken researchers

"The battery life of smart glasses is also an issue."

"If a traditional lithium-ion battery is used to supply MR smart glasses, the battery life will even be shorter than that of Microsoft's HoloLens..." Zhu Chen looked embarrassed.

Microsoft's HoloLens is a headset, and the available space is still quite large, but even so, the battery life is only about three hours.

The electronic components of smart glasses are all concentrated on the two temples, and the available space is far inferior to that of the head-mounted display. Otherwise, why did Microsoft choose the head-mounted display instead of glasses in the development of MR technology, it is naturally taken into account.

The smaller the space, the higher the difficulty.

Moreover, the glasses are not like head-mounted displays, but have more daily attributes, which requires higher battery life.

At least 8 hours of battery life, it is better to be able to charge once a day, but the narrow space simply cannot meet this condition.

Chen Hao understood what Zhu Chen meant and what the other party was worried about.

He patted Zhu Chen on the shoulder and affirmed: "You can rest assured with the lithium-air battery. I believe in Professor Bunier's ability, and you must also believe in it."

If the lithium-air battery cannot be miniaturized and used in MR smart glasses, even if they realize other functions perfectly, they will become a tasteless electronic product.

Who would accept a smart glasses with an hour or so of battery life?

Isn't that bullshit... some commuters take far longer than an hour to commute.

Traditional lithium-ion batteries cannot meet the requirements of smart glasses at all. Only the excellent performance of lithium-air batteries can solve the problem of battery life.

Zhu Chen glanced at Chen Hao and hesitated.

Principal, this is a lithium-air battery!

Who gave you so much confidence?

Zhu Chen and Jin Zhizhi looked at each other and had the same idea.

What else can I do, I can only hope that Professor Bunnier can conquer the lithium-air battery technology as soon as possible.

This topic can only be skipped, and Zhu Chen asked the next question: "By the way, there is also the chip problem of smart glasses..."

"Chip Simple!"

Chen Hao said easily: "The localization of optical cores is progressing well, and it will be completed in two or three months. At that time, I will arrange a team to develop optical cores suitable for smart glasses."

What Zhu Chen wants to develop is real smart glasses, not those "toys" developed under the gimmick of smart glasses.

Since it is not a toy, the computing requirements are quite high. 5g technology + optical core can perfectly solve this problem. Fortunately, this is relatively stable.

"The other is the sound problem."

"Sound problem? How to say?"

"For example, system prompts, listening to music, answering calls, etc., all need to sound. At present, there are two kinds of sounds in the laboratory. One is to learn from Microsoft's HoloLens, using external speakers + Bluetooth headset; the other is to use glasses. A bone conduction earphone module is added to the leg."

"In this regard, the laboratory has not yet unified opinions." Zhu Chen said with a headache.

The former does not take up space, and the technical problems are not high, but it is troublesome, users have to add a wireless headset in addition to wearing smart glasses;

The latter takes up volume, and also involves bone conduction technology and sound effects. The advantage is that you don't need to wear an extra headset.

As for bone conduction technology, which has emerged in recent years, it is mainly used for sports headphones.

Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, auger, auditory nerve, and auditory center.

Here is another example of the famous musician Beethoven.

As a famous musician Beethoven, he was deaf the day after tomorrow, but even so, it did not affect his creation of great works.

When Beethoven was playing, he bit a stick in his mouth and touched the piano body, which transmitted the vibration to the brain, and then heard the music.

This is actually the use of the principle of bone conduction.

It's just that bone conduction technology does not want in-ear headphones and headphones to mature, and there are two major problems: sound leakage and sound quality.

These problems have gradually been solved with the development of the times.

"Then which one do you two support?"

"Bone conduction."

"I also agree with bone conduction."

Jin Zhizhi and Zhu Chen agree.

Chen Hao smiled, "What else is there to worry about, let's join bone conduction technology."

"There are two good companies in China for bone conduction headphones: Nanka and Shaoyin. Then we can choose to cooperate with each other to solve the sound effect problem." After receiving the approval of Chen Hao, Zhu Chen felt much happier.

After all, he and Jin Zhizhi are too young and not qualified enough to suppress the different voices of the Institute and the Guanghua Institute (USA).

"What is the market value of these two companies?" Chen Hao asked suddenly.

"Market value?"

Zhu Chen was stunned and replied uncertainly: "It seems that these two companies are not listed. I don't know the exact valuation."

An unknown researcher next to him shouted.

"Principal, Shaoyin Technology's latest valuation exceeds 500 million." (No specific valuation can be found, fictional)

"500 million?"

Chen Hao looked at a young researcher, and smiled warmly, "Dr. Xu said the unit is RMB or US dollar?"

Hearing Chen Hao calling out his surname, the young researcher was stunned. He was so excited when he reacted, the big guy even remembered his name.

With so many people in the Intelligent Industry Research Institute, Chen Hao certainly won't remember them all, but just checked them temporarily with his insight skills.

Unexpectedly, the effect is not bad.

"It's RMB!"

After hearing that the unit is RMB, Chen Hao smiled.

Turning his head to face Zhu Chen and Jin Zhizhi, he smiled lightly: "500 million yuan is quite cheap, no need to cooperate, just buy it directly."

Bone conduction headphones are a good development direction, even if it is acquired at a premium, it will not exceed 1 billion yuan.

Only six or seven billion, not expensive.

But all the researchers present were stunned.

What kind of words are these tigers and wolves!

500 million yuan is quite...cheap...cheap...

These are five small goals. How many people can't earn 10 million in a lifetime, let alone 500 million.

Even Zhu Chen was shocked, as expected of the principal, he was still so domineering.

500 million RMB = 97.578 billion won.

If you can throw away 500 million at your fingertips, which private university president in the world has this capital...

Suddenly, Professor Jin was very pleased with his choice to join Guanghua University.

As for the latter question, it is not a big problem.

Except for the two major problems of chip and battery life, MR smart glasses cannot be solved for the time being, and other software and hardware problems are fine.

As for optical display technology, interactive technology, etc., it can be solved slowly.

Chen Hao stayed at the Intelligent Industry Research Institute until lunch time. UU Reading went to the canteen with Zhu Chen and Jin Zhizhi by the way.

But because of Chen Hao's appearance in the morning, there was an uproar among the researchers.

MR smart glasses technology is not a simple technology product. It is undoubtedly difficult to develop it with the technical reserves and environment of Guanghua University.

Especially with the passage of time, few breakthroughs have been made in the laboratory, many people are shaken, and the intention to retreat is even born in their hearts.

But things are different now.

Seeking truth on the edge of the lake.

Two doctors with worrying hairlines are arguing about something.

Both of them are researchers at the MR Smart Glasses Laboratory.

ps: Trying to stabilize the latest update, the data is really bad, it's good for the big guys to get some free recommendation tickets!
