Unexpectedly, in the face of Xia Yu's question, Huo Jianning shook his head with a wry smile and said: "Chairman, this is the walkman we developed, it has been eleven months since the project was established, and it is still an unqualified semi-finished product, and there is still a distance from the listing." ”

Huo Jianning didn't plan to hide it, and called the project leader directly, named Lu Chao, who was an expert in the field of electronics that Huo Jianning recruited from the United States, not only graduated with a doctorate, but also worked in General Electric Company before being dug up.

As a yellow race, Lu Chao did not stay comfortably in the General Electric Company, and the old General Electric Company had a strong bureaucratic atmosphere, and he could not completely concentrate on scientific research.

"Dr. Lu, this is Mr. Xia Yuxia, the chairman of the board, please tell him a little bit about the Walkman project. ”

Lu Chao, who is in his forties, wears glasses and doesn't seem to be very sophisticated, even if he learns that Xia Yu is the chairman, he simply shouts "chairman", and then picks up the semi-finished prototype to introduce it to Xia Yu.

"This walkman is currently positioned as a definite model, the measurements are 80x115x29mm, the weight is 300g, the power supply 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 side-by-side comparison between us and Sony's TPS-L2, and we are superior in every aspect. “

As he spoke, Lu Chao took out a comparison chart and handed it to Xia Yu.

Xia Yu took it and looked at it quickly.

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

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

Sony TPS-L2 Walkman measures 88x133.5x29mm, weighs up to 390g, has a battery life of 8 hours, the maximum power is 15mw + 15mw, and the frequency response range is 40Hz-12000Hz.

In terms of frequency response range and endurance, both are the same, the former is the most suitable range today, and 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 increased by a cut!

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

Who expected to hear Xia Yu's words of praise, Lu Chao shook his head and said: "In terms of sound quality, it is not inferior to Sony TPS-L2 Walkman, but it is only compared to Sony's Walkman, our products still have many shortcomings, I can feel that this is not the limit!"

"If the prototype production is brought to the market now, we can barely sell some, but it will not be able to give customers a feeling of surprise. ”

"Nineteen months have passed since the Sony TPS-L2 Walkman was introduced to the market in July 1979, and Sony must have developed a second generation of the product, most likely in production. ”

"The most obvious criticism of the Sony TPS-L2 Walkman is the size and weight, Sony will definitely make improvements for these two aspects, we were able to reduce the weight to 300g later, there is no reason why Sony can't do this, and even I guess that Sony's second-generation products will weigh less than 300g. ”

"If we finalize production and bring it to market now, there is a high probability that we will be defeated by Sony's second-generation product before we open up the situation. ”

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

Xia Yu smiled and nodded, Lu Chao was able to have this kind of requirement and awareness, which made Xia Yu believe that he could develop better products.

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

Lu Chao replied, "Yes!"

With that, he walked straight to a cabinet and opened it, then took out a silver-looking Sony TPS-L2 Walkman.

"Play the tape and compare the sound quality. ”

Xia Yu commanded.

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

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

After listening to a few songs in a row, Xia Yu did not comment, and pressed each button to experience the function, and then asked Lu Chao to use the self-developed Walkman to play the tape.

After a few songs, Xia Yu took off his headphones and commented: "In terms of sound quality, it seems to be better than Sony TPS-L2 Walkman, is it any technology?"

Lu Chao nodded and said: "Yes, our Walkman uses Dolby B-type noise reduction technology, and we have put a lot of effort into the jitter rate, and the handling accuracy has reached 0.05%WRMS." ”

"But correspondingly, these two technologies make it very costly for us. ”

Xia Yu immediately said: "It doesn't matter if the cost is high, in the case of lagging behind Sony, even if we don't make money, we have to set up the brand, and the product is good enough is the most important thing!"

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

Lu Chao's eyes froze, and he didn't get angry, but calmly asked Xia Yu: "Chairman, the authorities are obsessed with 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, but it is still not amazing enough, I will draw an appearance for your reference." ”

After speaking, Xia Yu found the white 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 if it is a rectangular iron box, he can also make tricks in details.

In less than five minutes, a sketch appearance picture came out, even if they only looked at the picture, Huo Jianning and Lu Chao could feel a delicate sense of vision.

The appearance of the Sony TPS-L2 Walkman is on par with it!

In later generations, the appearance of the Sony Walkman has been discussed by consumers, and has even been blown into the "shape designed by the traverser", which shows that the Sony Walkman has always led the trend in design.

But in front of Xia Yu, a real traverser, the appearance of the Sony Walkman cannot be compared.

After putting down the pen, Xia Yu interrupted Huo Jianning and Lu Chao's discussion, and continued: "The shape I drew can make a shell comparison, and the position of each function key can also be adjusted according to the situation, and then I will talk about the function." ”

"It's inconvenient to have to listen to a tape from beginning to end, so why not come up with a technology that allows our Walkman to roll automatically?"

"If it can be automatically flipped, then can we further develop the replay technology?"

"I just pressed the buttons, and it required a certain amount of force, and the sound was relatively loud, which was very unfriendly to the customer, and we could develop a touch button control system for this aspect. ”

"Also, the Walkman was further developed on the basis of the broadcaster, but now it has lost the FM radio function, we can control the weight and volume on the basis of adding this function, then the Walkman will impact the radio market. ”

"When it comes to the broadcaster, then recording and playback are also the functions of the broadcaster, but the Sony TPS-L2 Walkman does not have these functions, and we can also make our products have the function of recording and playback. ”

"There is also the most critical sound quality, although Dolby B-level noise reduction technology is now used, but since this technology can be licensed to us, then Sony must also be able to use it, after using this technology, although the sound quality has been improved to a certain extent, but I think it must be able to be more delicate. ”

“......”

Xia Yu said the common functions of the Walkman in later generations one by one, these are common functions that can no longer be common in later generations, but now saying it makes Lu Chao's heart tremble, and the pen in his hand quickly records it, for fear that he will miss something.

After all the records were completed, Lu Chao looked at Xia Yu with a blank eye, hoping that he would continue: "Chairman, do you have any other advice?"

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

Lu Chao immediately said: "It must be enough, as long as you can do it, it is not impossible to share the world with Sony on an equal footing, or even surpass Sony Company!"

"That's fine, you better develop what I'm talking about as soon as possible. ”

"By the way, the Walkman was invented by Sony, is there any restriction in terms of patents?"

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 said that Sony invented the Walkman, and this word was coined by Sony itself." ”

"In fact, the concept of Walkman was proposed by Americans in the late fifties, and the concept is 'portable, all-in-one, battery-powered portable audio player'. ”

"In 1964, Philips introduced the portable cassette recorder!"

And just last year, a German named Andrew Pavel took Sony to court for infringing on his concept patent for a stereo product system for personal wear, which is still being negotiated. ”

"We can ignore him for now, but we can also buy his patents privately so that he doesn't bite us like a mad dog. ”

"As for the basic technology of the Walkman, it has been used all over the world, and it is basically used in portable tape recorders. ”

"Even the word Walkman, although it was invented by Sony, we can still use it, because this word is not a trademark, so it does not meet the conditions for patent registration at all, and now the island nation Aihua Company and Panasonic Electric are also using the word Walkman. ”

"If you have to say that the patent is also restricted, it can be said, but the premise is that we want to use the technology developed by Sony, after listening to your guidance just now, our independent research and development technology is also enough, even if there is a little patent conflict, you can also use patent exchange to obtain. ”

"So when it comes to patents, there's no constraints. ”
