Compared with the electronic compass that can already be delivered directly, Saito Mototakeshi cares about two other things: the audio chip and the gravimetric accelerometer.

Although it is a giant in Japan's semiconductor industry, Asahi Kasei's audio chips are not owned by Shijie due to the presence of a more powerful STMicroelectronics company.

Even though Takeshi Saito believes that the audio chips made by his company have reached the first-class level of Shijie, because of STMicroelectronics' long-term monopoly position, the sales of Asahi Kasei's audio chips have not been very good.

There is also a gravity accelerometer, this Apple company has also approached Asahi Kasei, but Asahi Kasei was defeated in the end, and they don't know who exactly it will lose.

The so-called gravity accelerometer is a small metal kit built into the machine, because there are three axes to maintain balance, so at any time, this dhara-style metal accelerometer will remain horizontal and vertical, unwavering.

The gravimeter automatically senses changes in the orientation of the machine, so that it can adjust the function of switching accordingly.

Saito Takeshi knows,At present, Apple has used the gravity accelerometer in the mobile phone they developed,It is said that it can automatically turn the screen according to the direction of the handheld,This novel use of smart phones,Let Saito Takeshi very interested,Although the effect was not very good when it was developed before,But there has been a lot of progress in the end。

Takeshi Saito even believes that if he tries again, his gravity accelerator will definitely not lose to others.

Now it seems that there is no end to the sky.

Although Apple's order is gone, the materials, design drawings, etc. brought by this Chinese teenager are very professional, and they are also very in line with the characteristics of Asahi Kasei Microelectronics, which naturally interests Takeshi Saito.

The Japanese are much more attentive than the Americans, so Takeshi Saito is already tempted. But he was still very polite and asked Xiao Qi to leave the design drawings and plans for him to discuss with the researchers.

Of course, the necessary confidentiality agreement was signed in the presence of two staff members of Citibank, and Xiao Qi was not very confident about the credibility of the Japanese to the Chinese.

Saito Mototake to consider.

Belda's DRAM memory chips and Toshiba's NAND flash memory chips are not so particular. Because Jishu is mature and will not make modifications, they let Xiao Qi purchase it directly.

The difference between the two is actually very simple, DRAM memory chips are fast in real time, but unfortunately the data will disappear after the power is off, this kind of memory chip is usually used for playing games and using work software; NAND flash memory chips are stored for a long time and will not disappear after power failure, and are usually used on mobile phone memory cards.

To put it bluntly, DRAM memory chips are equivalent to the memory of ordinary computers. The NAND flash memory chip is equivalent to the hard disk of an ordinary computer.

Memory and hard disk.

It's that simple.

As a complete tablet, instant storage and power-off storage, both of which cannot be missing, so Xiao Qi is equipped with both, and there is no saving.

Because of the five-year contract, the large purchase of 30 million sets per year, and because the spring of the two memory chips has not yet arrived, it is negotiated. The price of each DRAM memory chip is $18, and the price of a 16GB NAND flash memory chip is $28 per chip. The price of a 32GB NAND flash memory chip is $55.

HOYA, which is controlled by the Suzuki family, a veteran Japanese optical company that has helped Huaguo build an optical glass industry, also has its own set of ambient light sensors.

This ambient light sensor, which has a similar function as a gravity accelerometer, is actually used on many high-end touch screens, but the merchants of Treasure Island are used to saving. Chenhong Optoelectronics did not use it on the electronic diagram sent to Xiao Qi's mailbox, because this would greatly increase the cost of the touch screen.

Xiao Qi couldn't laugh or cry when he heard it, so he could only add this item before he came to Japan. With a deposit of $10 million and a price of $1.5 each, a five-year contract was placed, and 30 million ambient light sensors per year were in hand.

Then for the first time, Xiao Qi sent the ambient light sensor of Tag Heuer Optics to Chenhong Optoelectronics, and asked them to install and integrate it on the touch screen no matter what, so as to achieve the best touch effect.

Three days after the initial meeting, Saito had agreed to Xiao Qi's contract, and the two parties signed a contract to supply the gravimetric accelerometer, electronic compass and audio chips in the presence of Citibank.

The price of the gravimeter is $1.8, the price of the electronic compass is $1.5, and the price of the audio chip is $1.2, which is also 30 million sets per year, and the contract is still five years.

As long as Xiao Qi does a good job of his motherboard CPU and GPU, then Asahi Kasei Microelectronics will carry out various debugging according to the motherboard to make the most suitable products for the tablet motherboard chip.

THE 5MM SIZE CAMERA ASSEMBLY IS NOT A VERY THIN SIZE IN TODAY'S MOBILE PHONE INDUSTRY, BUT THE IPAD IS RELATIVELY LARGE, SO THE SIZE OF THE CAMERA CAN BE TOLERATED BETTER THAN THE MOBILE PHONE.

THE 5MM CAMERA WAS RECEIVED BY RICOH CO., LTD. OF JAPAN.

Although from a professional point of view, Ricoh is not as professional as Canon and Nikon, but its professionalism is stronger than that of Sony, Olympus, etc.

In terms of thin and light cameras for mobile phones, Ricoh's Jishu is also sufficient, and most importantly, the cameras it supplies are much cheaper than Sony's gorgeous appearance, and the quality is better.

Ricoh has been thrown away by Canon and Nikon in professional cameras over the years, and has been slapped in the face by Sony and Olympus on the card machine, and is almost ready to give up the development of this piece.

The price quoted by Ricoh is $2.3 per piece, which will be supplied for five years, 60 million sets per year, and the annual camera pixels must rise by at least one million, which is very fair.

XIAO QI VAGUELY REMEMBERED THAT THE COST PRICE OF THE IPAD2'S 700,000 PIXEL CAMERA SEEMED TO HAVE REACHED TWO DOLLARS A PIECE, WHICH MADE EVERYONE CRITICIZE AND SARCASM LATER, AND QIAO GANG LEADER WAS ANGRY AND DIRECTLY DISMISSED THE VICE PRESIDENT IN CHARGE OF PROCUREMENT.

WHEN IT COMES TO THE IPAD 3, THE PIXELS WILL GET BETTER, BUT THE PRICE IS ABOUT $2.5.

Although the price of mobile phones and tablet PCs in the future, with the development of Jishu, will be reduced to about one dollar, the price of high-end cameras has been relatively firm, and it still fluctuates around two dollars. (To be continued.) )
