Rebirth of the Strongest Tycoon

Lu Chao said humbly, "Chairman, it's mainly your credit."

After speaking, he explained: "The most difficult part of a technology is the experimental period of finding the path. It needs to do dozens, hundreds or even thousands of tests, and constantly explore to find the correct method and path, which is from scratch. The exploration is the most labor-intensive and resource-intensive.”

"But you told me about the principles of photoelectric conversion technology and pulse technology last time. According to the direction you said, we quickly found the correct research and development path, and the company is also constantly digging scientific research talents to join, regardless of cost. resources, so the results can be achieved so quickly.”

Xia Yu suddenly understood.

It seems that the hook he opened was used by Lu Chao.

But this also reflects Lu Chao's powerful ability. Knowing the principle is one thing, and being able to develop it from scratch is another.

"Dr. Lu, you don't have to be humble, you and your team have a huge credit for developing it so quickly!"

As Lu Chao faced Huo Jianning, he said, "Jianning, remember these things. You should reward Dr. Lu and his team at the end of the year. Don't be stingy."

"Okay, Chairman!"

Huo Jianning responded obediently.

A knowing smile appeared on Lu Chao's face. Although he didn't like money, he also knew that other members of the team needed money to live. The chairman could pay attention to these, which made him feel very comfortable.

When you are in a good mood, your motivation to work will naturally be high.

He excitedly said to Xia Yu, "Chairman, please come with me, the CD Walkman is in another laboratory."

...

Soon, everyone came to the CD Walkman laboratory.

This time, without having to say anything about Xia Yu, Lu Chao directly took out a sample of the CD Walkman, and also took out a CD in a box.

The CD Walkman is different from ordinary portable players. The most intuitive aspect is the shape. It is a box with a smaller thickness and similar length and width. There is also a round cover on the surface that almost touches both sides. Xia Yu knows where it is at a glance. It's a CD.

Sure enough, Lu Chao gave an introduction and a demonstration.

He pressed a button, and the round cover on the CD Walkman shot up. He introduced: "Chairman, the playback principle of this CD Walkman is the same, just put the CD in, change the cover, and press Press the play button to play music."

"The disc has already recorded songs, and I personally think the sound quality of the songs is better than the vinyl."

After speaking, Lu Chao put the CD in, then pressed the play button, picked up the headphones and handed it to Xia Yu.

After Xia Yu took it, he put it in his ear, and closed his eyes and listened.

A minute later, he took off his earphones and said with a little satisfaction, "Yes, the sound quality is clearer than that of vinyl records."

At this time, Lu Chao poured cold water and said, "Chairman, you and I both think that the sound quality of CD records is better, but we have done tests before. The same songs are recorded on vinyl records and CD records. A small number of people think that the sound of CDs is distorted and not as real as vinyl."

A comparison test has been done!

This argument has already appeared as soon as it was developed!

He remembers that in the past, the music industry and listeners had quarreled over the reproducibility and distortion of the sound of CD records and vinyl records.

I don't know what is the opinion of Lu Chao, an eye-catching researcher?

He asked curiously, "Dr. Lu, do you think CD records are more distorted than vinyl records?"

Lu Chao shook his head without hesitation and said, "Of course not, I think CD records are more realistic!"

Without waiting for Xia Yu to ask, he directly stated the basis for his opinion.

"Chairman, I am making dialectical comparisons from a scientific point of view."

"In fact, as long as you understand the difference between the recording methods of CD records and vinyl records, you can make a clear and positive judgment."

"The vinyl is produced by the sound and electrical signal-mechanical signal platter pattern,

There seems to be no loss in this process, but in fact, the mechanical loss is particularly large. Any mechanical transmission will be affected by the environment, temperature, gravity and other aspects. This problem also exists when the vinyl record is released again. "

"And the master tape of vinyl must have the least loss. If you want to copy and burn it, it will only be more and more loss. Consumers can only get copy and burn discs instead of master tapes."

"The CD is generated by digital sampling and recording of digital signals, and there is indeed a loss in the sampling process, because the sampling rate determines the audio range, but the sampling rate of CD is high enough to exceed the range of human hearing, so from this point It doesn't make sense to look at the so-called 'lossy', the loss is the part that is inaudible to the human ear. This one loss can be described as "clearly priced", and the entire CD system has no other loss other than this loss."

"Of course there's the loss of wiring equipment, but vinyl has the same problem, so it's balanced out."

"Once the analog signal is digitized, it is lossless whether it is transmitted or copied and recorded. The data on the CD has sufficient redundancy and error correction functions to ensure that the copied disk and the master tape are exactly the same."

"So with the same equipment level, the sound quality of CD records is definitely better than that of vinyl records!"

After listening to Lu Chao's concise and clear analysis, Xia Yu suddenly understood.

In this analysis, the sound quality of CDs is indeed better.

Of course, everyone's auditory system is different, there are always people who are different, not to mention the existence of hearing illusions, which is destined to be controversial after it is introduced to the market.

But a small number of people can give up directly, and then slowly assimilate!

Later, he read the product manual of this CD Walkman, and learned that the model is Tiangong CD-P1, the body measurements are 130x140x17mm, the body weight is 290g, the headphone weight is 18g, the power supply is two dry batteries, the battery life For 8 hours, the maximum output power is 20mw+20mw, and the frequency response range is 40-22050Hz.

The upper limit of the frequency response range of the CD Walkman is almost double that of the vinyl Walkman!

Generally speaking, in the range that the human ear can sense, the larger the upper limit of the frequency response range, the more three-dimensional the sound you hear.

This is a big selling point.

Xia Yu put down his Walkman and took out the CD-ROM alone. After looking at it, he asked, "Dr. Lu, are there any loopholes in the patent for CD-ROMs? How far have Sony and Philips researched?"

After recalling for a while, Lu Chao replied in detail: "Chairman, thanks to President Huo in terms of patents, thanks to him, we can have a certain advantage in technology patents."

Xia Yu raised his brows slightly and looked at Huo Jianning in surprise, but saw Huo Jianning smiling modestly.

Xia Yu smiled and said, "Jianning, tell me how you did it?"

Huo Jianning then said what he had done before: "Actually, I heard Dr. Lu say before that in the field of CD laser discs, there are many companies in the world that are conducting research and development, but the pioneers are Sony and Philips of the Netherlands. The two companies developed the Red Book standard in 1980, which is nothing more than the CD-DA disc standard."

"The CD-DA disc standard includes many basic technologies for CD discs, and not all of these patented technologies are occupied by Philips and Sony, but these two companies have exchanged patents and exchanged them with other companies in the world. Part of the patent, and then preemptively develop the Red Book standard, ready to become the industry standard setter and occupy the highest position.”

"When the Red Book standard was first released, Sony and Philips also took the lead, and other large companies were catching up, so they also needed more companies to recognize the Red Book standard and fill the track in advance, as much as possible. Avoid other peers grouping together to set another standard."

"At that time, we had not released the Tiangong SP-S1 Walkman, and the relationship with Philips and Sony was not bad, so I applied to join the Red Book standard in advance, obtained the right to use the basic patented technology, and paid for some patents. "

"That's it."

As soon as Huo Jianning finished speaking, Lu Chao said, "Combining the technology of the Red Book standard, I have developed a CD-ROM format according to your guidance, Chairman."

"According to the information I have learned, Sony and Philips are also doing related research and development, but I can be sure that they have not developed a finished product yet, and we have caught up later."

"Because the patent was going to be registered, the news that we were working on the technology inevitably leaked, sparking hostility from Sony and Philips, but that doesn't matter now."

"I see."

Xia Yu said softly, the whole situation was clear.

He smiled and praised Huo Jianning: "Jianning, you did a good job of taking precautions!"

Huo Jianning said humbly: "Thank you for the praise from the chairman. I learned from you. I take three steps to do things."

Xia Yu couldn't help but smile.

Huo Jianning succeeded in stealing chickens, avoiding great trouble for Tiangong Electronics and solving the problem of basic patents.

Fortunately, Tiangong Electronics joined the Red Book standard when it was harmless to humans and animals, and purchased patents. If this is the case, Tiangong Electronics will never be able to buy patents. Philips and Sony will definitely block the technology and let Tiangong Electronics. I\u0026E has a second-generation technology, and it cannot be commercialized.

"Of course, Dr. Lu, thanks to you for developing the technology so quickly, thank you for your hard work!"

Xia Yu looked at Dr. Lu Chao again and said with certainty.

Lu Chao replied modestly: "Chairman, researching technology is my duty, otherwise I would be embarrassed to receive such a high salary from you."

Xia Yu smiled, and instead of worrying about it, he asked the last key question.

"After listening to what you said, I probably understand, that is to say, this is a finished product, can it be brought to the market?"

Hearing this question, Lu Chao looked helpless and looked at Huo Jianning.

Huo Jianning looked embarrassed and said, "Chairman, there are still two problems with this CD Walkman. I can't make up my mind, and I still need your instructions."

Xia Yu's eyes narrowed slightly, and he nodded slightly: "Tell me, which two questions."

PS: I went out and got home at 10:20 in the evening, so today I can only write this chapter with 3,000 words, and I will update it tomorrow.
