Chapter 1O2 Technical Roadmap: Upper (Four Changes, Three Changes)

Lang Xuan understood what Lin Zheng was laughing at, and his face couldn't help but turn red, "I just think that we only produce cassette Walkman is too simple, and the cassette Walkman and CD Walkman should be opened together, and I also learned some relevant information about the Walkman during this time......"

Saying this, Lang Xuan unconsciously touched his face, but in his heart he felt that his face was blushing inexplicably.

"Only a cassette Walkman is definitely not good, or even only a Walkman is definitely not good, we should take a long-term view." Lin Zheng nodded, Lang Xuan's insight made him admire it a little.

Lisheng Walkman has now become a domestic brand, but this is not his goal? So what exactly does he want to do? Lang Xuan secretly glanced at Lin Zheng.

"Sister Lang, the scale of the company will be large in the future, and it is not only unrealistic to rely on me to do the design, but also not the state that a company should have. Lin Zheng said.

The company's current financial and technical strength is limited, and it is not wrong to do its best to grasp the main problems, but it is unrealistic for the company to do its own design after it is on the right track.

"Okay," Lang Xuan responded, but then frowned, "But there are no good design talents in China, right?" ”

"No, it doesn't matter, we can cultivate ourselves and introduce it from the outside, we can't let this situation continue, the company is now small, I have no problem doing design for a few years, but after a few years, I can't always do design, right?"

He is so confident that in a few years the scale of the company will expand to the point where he can no longer concentrate on designing. Looking at Lin Zheng's confident face, Lang Xuan was slightly surprised: Is this little guy full of confidence, or is he arrogant and can't figure out his own weight?

"Kong Gong, we meet again," Holding Kong Xiaoming's hand hard, Lin Zheng smiled happily, "Work is still smooth, right?" ”

"Smooth and smooth," Kong Xiaoming was wearing a clean white coat, pushed the gold wire glasses on the bridge of his nose that had been changed for less than a month, and smiled from ear to ear, "Mr. Lang takes good care of us in work and life, there is the best research equipment and salary, and the big guys are very satisfied." ”

"I'm relieved if everyone is satisfied, and I'll tell you, even if you're not satisfied, I won't dare to trouble Mr. Lang." Lin Zheng said with a smile.

Knowing that this was Lin Zheng joking, everyone laughed very happily, even Lang Xuan laughed very happily, and did not forget that Jì secretly glanced at Lin Zheng, for this boss who was both like his brother and his friend, Lang Xuan couldn't really treat Lin Zheng as his own boss when he treated him.

After laughing, Lin Zheng spoke, "Everyone knows that although the sales of our cassette walkman in the market are better than expected, but only such a product is definitely not normal and should be, and our competitors cannot watch us toss and be indifferent, and it is imminent to open and improve the product line. ”

"I brought you a bunch of exterior design drawings, and now that the 'house' is there, it's time for everyone to 'decorate'...... Kong Gong, in the system selection of CD Walkman, we have determined whether it is a single-bit system solution or a multi-bit system solution? ”

As early as half a month ago, Lin Zheng gave Kong Xiaoming the request to choose a CD walkman solution suitable for his company, and asked Kong Xiaoming to lead the company's engineers to discuss, and now it is time to come out with the results.

Kong Xiaoming nodded, "Sure, we think that the single-bit solution is more suitable for our company." ”

"Okay, just a single bit." Lin Zheng did not hesitate and immediately made a decision...... From Lin Zheng's heart, he is actually more inclined to the single-bit solution.

"What is a single bit?" Lang Xuan whispered to Lin Zheng and asked, "Do Sony, Panasonic, Aihua and JVc Japanese Walkmans use single bit or multiple bits?" ”

"This problem should be discussed from the basic structure of the CD player," Lin Zheng explained to Lang Xuan in a whisper, "In essence, the CD Walkman is no different from the kind of home desktop CD player, it is a digital converter, and the basic structure is the same, usually divided into several parts, such as reception, digital filtering, d/a digital/analog conversion, I/V conversion, analogue amplification, etc., the most important part of which is the two parts of digital filtering and digital/analog conversion. Analog converters can be roughly divided into two main streams: one is multi-bit element, also known as multi-bit system; The other is the unit element, also called the single-bit system and the one-bit system. ”

"The multi-bit system is dominated by Japanese companies such as Sony, Panasonic, and JVc, and the single-bit system is dominated by another controller of CD patents: Philips.

"Philips is actually very sad, they are the original CD standard makers, and now they still rely on the CD standards in their hands every year to extract profits from all over the world, but unlike Japanese brands, they are very bad in the market for specific CD products, Sony, Panasonic, Aihua, JVc and other companies rely on the CD-related technical standards in their hands, not only collect patent fees around the world, but also make a profit by selling products, although Philips also has products, However, the market coverage and popularity of CD products are much worse than those of Japanese products. ”

In China, there are few people who don't know about Japanese cassettes and CD Walkmans, but there are also few people who know that Philips also has CD Walkmans.

"Understood," Lang Xuan nodded clearly, "It's because Japan uses mostly multi-bit solutions, and most of the chips are produced by Japanese companies, so in order not to be controlled by others, you decided to use Philips' single-bit solution?" ”

Philips' CD Walkman products have a very bad market share, and it is basically impossible to cooperate with Japanese companies, Japanese companies cannot cultivate a competitor of their own, and cooperation with Philips is the only feasible solution, after all, as the controller of CD patents and standards, Philips holds all the patents from movement manufacturing to chips and transmission protocols, even if it is to crack down on Japanese companies, they are willing to cooperate with Lisheng Electronics. In Lang Xuan's opinion, that's what Lin Zheng thought in his heart.
