Chapter 163 Mobile Phone Prototype (Part [-])

Mayor Peng and his party stayed at the electronics factory until four o'clock in the afternoon before leaving. After that, Qiao Ruida called Zhao Yulong, explained the follow-up matters, and left the factory.

All day long on May 5, Qiao Ruida stayed at home with her parents and sister. As the old saying goes, parents should not travel far away if they are still alive. This is filial piety. But in modern society, it is common for people to go to school or work, thousands of miles away from their hometown, and stay there for half a year. If you want to fulfill your filial piety, you have no chance. Qiao Ruida is a person who cherishes family ties very much. After she was admitted to college, she would call her parents at least once a week. Whenever she had the opportunity, she would drive home, even if she would have a meal with her parents or watch TV for a while. It's also good.

On the 4th, the long holiday was over, and Qiao Ruida left her hometown in a Mercedes-Benz early in the morning and returned to the capital. During this short vacation, Du Qingqing signed up for a debate competition organized by the school and did not return to Decheng City with Qiao Ruida. In fact, from Qiao Ruida's point of view, those so-called debate competitions are all just a bunch of college students chewing words and competing for eloquence. They are of little significance to themselves and society. However, if my girlfriend likes them, I can only let her go.

At noon that day, Qiao Ruida rushed to Peking University, put her suitcase and some specialties brought from her hometown back to her dormitory, then picked up her textbooks and went straight to the teaching building. The first class in the afternoon is "Microelectronics" taught by Academician Wang Chengye. This is also the only undergraduate course taught by an academician in the integrated circuit major. Academician Wang's lectures rarely follow the textbook, but use chip design cases to explain relevant knowledge points. It is worth listening to, and Qiao Ruida attends almost every class.

Two hours later, after finishing her first class, Qiao Ruida drove away from Peking University and came to Shijia Hutong. The courtyard house he bought has begun to be renovated and renovated. From time to time, he or Du Qingqing needs to come over to take a look. They need to decide on some internal room layouts and decoration styles.

There were no important classes in school the next day, so Qiao Ruida simply skipped class and came to the company. As soon as he sat down in the office, R&D manager Xiao Jingsheng came to his door.

"Boss, the prototype of the smartphone we developed is out. Can you take a look and see what else needs to be modified?" As he said that, Jamel Xiao took out a smartphone with a white back case and placed it in front of Qiao Ruida. Look at it. His expression was clearly showing off.

"Oh, it's coming out so soon, doesn't it mean it will take a few more days? Could it be that you haven't gone home during this short holiday and have been working overtime." Qiao Ruida asked with some confusion.

Jamel Xiao raised his hand, scratched the back of his head, and chuckled twice, "It's not like the mobile phone sample was about to come out. Everyone was very anxious, so we worked overtime for three days to get rid of it."

"What I said at the beginning is that our company does not advocate overtime. Only a combination of work and rest, and a steady stream of work can create the greatest value for the company. You people just don't listen. You have to work overtime during the May Day holiday. What are you trying to do? How late are you? No one will criticize you if the prototype comes out. Okay, it’s just this once, it won’t happen next time.” After scolding Xiao Jingsheng, Qiao Ruida then picked up the prototype and started checking it out. The front of the phone is a 5.5-inch LCD screen produced by BOE. The top of the screen retains a half-finger-wide frame, which houses the camera, earpiece, and various sensors. Below the screen, there are three physical buttons for the Android system. On this mobile phone, Qiao Ruida originally planned to have a water-drop full screen or a punch-hole full screen. However, after consulting mobile phone screen suppliers such as BOE, Four Star, and Sharp, she realized that with today's technology, it would be difficult to make a water-drop screen or a full-hole punch screen. Perforated screen. Where holes are opened, problems such as chipping, blackening, and disconnection are prone to occur. In desperation, I could only choose a fairly good IPS LCD screen, while minimizing the width of the forehead and chin of the phone, increasing the screen-to-body ratio to about 85%.

The middle frame of the mobile phone is made of metal, showing a silvery white color. It is brushed and the corners are chamfered. It is smooth and round in the hand without any cutting feeling. In order not to affect signal conduction, several symmetrical cuts were made on the frame and filled with white plastic. On the right side of the phone, there is the startup button and two volume adjustment buttons. There are speaker openings, infrared openings and 3.5 headphone jacks on the top of the phone. There is no need to think about waterproofing. The bottom of the phone has a type-c interface, earpiece opening, SIM card opening and speaker opening. When you see these two speaker openings, you know that this phone supports stereo playback. When Qiao Ruida originally designed this phone, she considered using the music phone as one of its selling points, and specifically enhanced the music playback capabilities. In addition to the two stereo speakers, an independent decoding module and an independent decoding module were added to the circuit board. The power amplifier chip is very good in terms of music analysis capabilities and headphone thrust, which is comparable to professional music playback equipment.

The back of the phone is a white glass back panel with arcs on the four sides. It feels very warm and smooth to the touch, and feels very good in the hand.

Seeing this, Qiao Ruida asked curiously: "I see that the back shell of this mobile phone is made of glass, not plastic. Have you solved the problem of the strength of the glass?"

Jamel Xiao shook his head with some regret and said: "We have not solved it. Several domestic special glass factories have also asked, and they cannot provide glass back shells with such strength. The back shell used now is from a big manufacturer in Chou Country. Customized by the Orangutan Glass Factory, it is very strong, light in weight, and has a good texture, which perfectly meets our requirements. However, the price is too expensive, and even if purchased in large quantities, it will cost more than [-] yuan to buy a shell."

Hearing this quotation, the corner of Qiao Ruida's mouth twitched uncontrollably several times, "It costs more than thirty yuan for a mobile phone back case, why don't they grab it. These ugly country devils are so evil! Forget it, in order to improve The quality of the mobile phone is more expensive. Every experience makes you wiser. With this lesson learned, we must speed up the research and development of related glass materials and strive to use our own glass materials on the second generation of Ritar mobile phones. High strength glass.”

"Yes, I think so too. I have asked the company's human resources department to help find a few glass experts to strengthen the R&D strength of our R&D department in related aspects and strive to win the production of this high-strength glass this year. technology."

Qiao Ruida nodded, and then continued to look at other parts of the mobile phone prototype. On the upper back of the phone, there is a 1200-megapixel camera.
