v3 Chapter 945： Tiangong Walkman

Unexpectedly, facing Xia Yu’s problem, Huo Jianning shook his head with a wry smile and said: "Chairman, this is a Walkman we developed. It has been 11 months since the project was approved. It is still a substandard semi-finished product. distance."

Huo Jianning also did not intend to hide and cover her head. He directly called the project leader, Lu Chao, an expert in electronics field that Huo Jianning dug from the United States. He not only graduated with a doctorate, but also worked for General Electric before being dug.

As a yellow man, Lu Chao didn’t feel comfortable staying at General Electric, and the veteran General Electric had a strong internal bureaucracy. He couldn’t completely meditate on scientific research. When Xiangjiang’s Tiangong Electronics Co., Ltd. offered him an olive branch. Later, after understanding the situation, Lu Chao decided to quit and brought his family to Xiangjiang.

"Dr. Lu, this is Mr. Xia Yuxia, chairman of the board. Could you please tell him some information about the Walkman project."

Lu Chao, in his 40s, wore glasses and seemed uncomfortable. Even if he learned that Xia Yu was the chairman, he simply called out "Chairman" and then picked up the semi-finished prototype to introduce to Xia Yu.

"This Walkman is currently positioned to determine the model, the measurements are 80x115x29mm, the weight is 300g, the power source is two dry batteries, the battery life is 8 hours, the maximum output power is 20mw+20mw, and the frequency response range is 40-12000Hz."

"This is a comparison of horizontal parameters between us and Sony TPS-L2. We are superior in every aspect."

With that, Lu Chao took out a comparison chart and handed it to Xia Yu.

Xia Yu took it and looked quickly.

The comparison chart is very concise and clear. On the left are the parameters of the world's first Walkman Sony TPS-L2, and on the right are the parameters of the Walkman developed by Tiangong Electronics.

The arrow above each row in the middle indicates the amount of optimization.

The Sony TPS-L2 Walkman has measurements of 88x133.5x29mm, a weight of 390g, a battery life of 8 hours, a maximum power of 15mw+15mw, and a frequency response range of 40Hz-12000Hz.

In terms of frequency response range and endurance, both are the same. The former is the most suitable range today, while the latter is limited by battery technology and cannot be changed.

The most obvious is that the volume has become smaller, the weight has become lighter, and the maximum power has been improved a bit!

Xia Yu commented: "According to the current parameters, the market can also stand up, but the premise is that the sound quality is good."

Unexpectedly, after hearing Xia Yu’s praise, Lu Chao shook his head and said: “The sound quality is no less inferior to the Sony TPS-L2 Walkman, but it is only compared to this Sony Walkman. We have many more products. Shortcomings, I can feel that this is not the limit!"

"If the finalized production is launched to the market now, it can barely sell some, but it can't give customers an amazing feeling."

"The Sony TPS-L2 Walkman was introduced to the market in July 1979. Nineteen months have passed since then. Sony must have developed a second-generation product, and it is likely to be in production."

"The most obvious thing about the Sony TPS-L2 Walkman is the size and weight. Sony will definitely make improvements in these two aspects. We will be able to reduce the weight to 300g afterwards. There is no reason that Sony cannot do it. At this point, I even guess that Sony’s second-generation product will weigh less than 300g."

"If we now finalize the production and launch it to the market, it is very likely that we will be defeated by Sony's second-generation products without opening the situation."

"So now this product is just a semi-finished product!"

Xia Yu smiled and nodded. Lu Chao can have this kind of request and awareness, which makes Xia Yu believe that he can develop better products.

After thinking about it, Xia Yu asked Lu Chao: "Is there a Sony TPS-L2 player in the laboratory?"

Lu Chao replied: "Yes!"

After speaking, he went straight to a cabinet and opened it, and then took out a silver-looking Sony TPS-L2 Walkman.

"Play the tape and compare the sound quality."

Xia Yu ordered.

Lu Chao nodded, directly loaded the battery, then put the tape, pressed the start button, and silently passed the headset to Xia Yu.

Xia Yu took the earphones and put them into his ears, and the melodious singing voice came into the ears. Xia Yu closed his eyes and felt the sound quality carefully.

After listening to a few songs, Xia Yu didn't comment, and pressed each button to experience the function, and then let Lu Chao play the tape with his self-developed Walkman.

After a few songs, Xia Yu took off the headphones and commented: "The sound quality seems to be better than the Sony TPS-L2 Walkman. What technology is used?"

Lu Chao nodded and said: "Yes, our Walkman uses Dolby B noise reduction technology, and we have worked **** the jitter rate, and the transport accuracy has reached 0.05% WRMS."

"But correspondingly, these two aspects of technology make our costs very high."

Xia Yu immediately said: "It doesn't matter if the cost is high. In the case of lagging behind Sony, even if we do not make money, we must establish the brand. The most important thing is that the product is good enough!"

"But now in my opinion, this product is indeed a failure, and it has a lot of room for improvement!"

Lu Chao's eyes condensed and he was not angry. Instead, he calmly asked Xia Yu: "Chairman, the authorities are obsessed with the bystanders, what do you think needs to be improved?"

Xia Yu was not polite and said directly: "First of all, the appearance. Although the current appearance is obviously different from the Sony TPS-L2 Walkman, it is still not amazing enough. I will draw an appearance for you to refer to."

After speaking, Xia Yu found the blank paper and pen, thought for a moment, and began to draw quickly on the paper.

After all, he has experienced the baptism of various electronic products in later generations. Even a rectangular iron box can make tricks in details.

In less than five minutes, Huo Jianning and Lu Chao could feel a delicate visual sense even if only looking at the pictures.

The appearance of the Sony TPS-L2 Walkman compares favorably with it!

In later generations, the appearance of the Sony Walkman has been talked about by consumers, and has even been blown up as a "transmitter-designed shape". This shows that the Sony Walkman has been leading the trend in design.

But in front of Xia Yu, a real traverser, the appearance of the Sony Walkman is incomparable.

After putting down the pen, Xia Yu interrupted the discussion between Huo Jianning and Lu Chao, and continued: "The shape I drew can be compared with a shell. Each function key can also be adjusted according to the situation. Next, I will talk about the function. aspect."

"A tape must be listened to from beginning to end, which is very inconvenient. Why not develop a technology that allows our Walkman to automatically turn over the tape?"

"If the tape can be automatically turned over, can it be possible to further develop repeat playback technology?"

"I pressed each button just now. It requires a certain amount of force and the sound is relatively loud. This is very unfriendly to the customer. We can develop a touch button control system for this."

"Also, the Walkman was originally developed on the basis of the broadcaster, but now it has lost the FM radio function. We can re-add this function on the basis of controlling the weight and volume, and the Walkman will have an impact. The market for broadcasters."

"Speaking of broadcasters, recording and playback are also functions of broadcasters, but the Sony TPS-L2 Walkman does not have these functions. We can also make our products have recording and playback functions."

"There is also the most critical sound quality. Although the Dolby B noise reduction technology is now used, since this technology can be licensed to us, then Sony must be able to use it. After using this technology, the sound quality has improved, But I think it can be more delicate."

"..."

Xia Yu explained the common functions of the walkman in later generations one by one. These are functions that are so common in later generations that they can no longer be common. But now that he said it, it made Lu Chao's heart tremble, and the pen in his hand quickly recorded it. , For fear of missing something.

After all the records were completed, Lu Chao looked at Xia Yu eagerly, hoping that he would continue to say: "Chairman, do you have any pointers?"

Xia Yu was a little bit dumbfounded, and said, "Dr. Lu, I have thought of these for the time being, but if these are all developed, do you think it is not enough to fight Sony?"

Lu Chao immediately said: "It must be enough, as long as it can be done, it is not impossible to share the world with Sony, or even surpass Sony!"

"That's not enough, you should develop what I said as soon as possible."

"By the way, the Walkman was invented by Sony. In terms of patents, are there any constraints?"

Xia Yu asked with concern.

Lu Chao shook his head and said: "Chairman, you are wrong. The Walkman was not invented by Sony. Sony only invented the Walkman, not the Walkman. If you pay attention, you will find that Sony’s own propaganda only mentions Sony. Invented walkman, and this term was coined by Sony itself."

"In fact, the concept of Walkman was put forward by the Americans in the late 1950s. The concept was'portable, integrated, battery-driven portable audio player'."

"In 1964, Philips introduced a portable radio recorder!"

"And just last year, a German named Andrew Pavel from UU Reading also sued Sony on the grounds that Sony had infringed on his concept patent-the personal stereo product system. Both parties are still negotiating."

"We can ignore him for now, but we can also pay a little money to buy his patents in private to prevent him from biting us like a mad dog."

"As for the various basic technologies on the Walkman, they have been used all over the world, and they are basically used in portable radio cassette recorders."

"Even though the word walkman was invented by Sony, we can still use it. Because this word is not a trademark, it does not meet the requirements for patent registration. Now the island country Aihua Company and Matsushita Electric are also using walkman. this phrase."

"If we have to say that there are restrictions on patents, it can be said, but the premise is that we use the technology developed by Sony. After listening to your instructions just now, the technology we independently developed is sufficient, even if there is a patent conflict. , Can also be obtained through patent exchange."

"So in terms of patents, there are no constraints."
