Yang Chunsheng is in a good mood these days.

For him, getting rid of the distressing "burden" of Beacon Fire and joining Polestar Electronics lightly can be regarded as a relief.

In the current industrial environment, Beacon will survive even if it is supported by itself, but Polestar is full of hope.

During the eleventh period, the sales volume of Polaris K1 was not optimistic, of course, this is only compared with historical results, and the total sales of 9,000 units in the end are expected to be the champion of single products in the entire market.

However, after all, the popularity of Cheng dù is declining, and the financial pressure of Polestar Electronics' upcoming headquarters has begun to become prominent, and the research and development of Polaris K2 has become a top priority. He also temporarily put down the research and experiment of the second-generation master control scheme and transferred to the K2 that Song Xiaogang's team is currently responsible for.

These days, Song Xiaogang has led the team to complete the test of 65,000 colors of the CSTN screen, approaching the theoretical upper limit.

At the same time, they also determined the choice of filters, and the display effect of the new screen has been improved by nearly 80%, with a 2.4-inch screen with 160×128 resolution, which has definitely reached the first-class level on the market.

But on the sound side, it was completely stuck.

Sound is also a very important part of music players. In contrast, sound quality refers to clarity and realism, while sound effect refers to sound effect, which is "the sound effect that enters the ear", which can be said to be related to the final effect.

For Xia Yu, who wants to make higher quality, although the Polaris K1 does not use any special sound effects, and can achieve some success with the EQ mode alone, he still hopes to have a better configuration as much as possible.

As a result, he brought forward several well-known sound effects in the future, such as SRS, BBE, etc.

In Xia Yu's impression, SRS is also an old sound effect, and some low-end models of international brands also use this, but domestic companies also use a lot, Xia Yu always feels that this is not enough to stand out.

Although Xia Yu's positioning of K2 is only an upgrade of K1, not a new generation of products, but now the competition is so fierce, there are enough killer features to rest assured.

Therefore, he first told Yang Chunsheng whether he could get the authorization of BBE.

In fact, how can there be any domestic machines on the market that can really make sound effects? At most, foreign companies such as Samsung, iRiver, and iAudio are the main ones, and they also have the strength and confidence.

But the licensing of BBE sound effects is really not a simple matter.

Polestar Electronics only had five days off during the eleventh day, and the R&D department only had three days, and Yang Chunsheng took over the errand as soon as he returned.

He often has to deal with such companies when doing scheme design, and he knows a lot about this aspect, but when it comes to BBE, he can't open the door for a while.

BBE technology originated in 1985, and after several generations of development, it has developed from the original patented technology applied to power amplifiers to AV audio-visual, Walkman, radio, CD and now digital audio technology, and has the reputation of "after the sound effect".

However, BBESound, the patentee of this technology, does not have an office in China, and in fact, there is no second company in the market except for the high-ranking COWON iAudio, which has obtained the BBE license.

Yang Chunsheng relied on his contacts who had worked hard in the circle before, and found a way to find the news about the licensing of BBE sound patents.

According to a friend, since BBESound has always had a very strict quality control for BBE technology, to put it simply, although the licensing fee of BBE technology is very low, it is not so simple to get BBE authorization.

Generally speaking, after a company applies to BBESound, they will first send someone to investigate the company and recognize its strength before issuing an authorization. In the design process of products using BBE technology, they will participate in the design of the sound part, and only after the final sound quality has been approved can the product be marked with the BBESound trademark.

It is precisely in this rigorous way of operation that the BBE trademark has become a symbol of high quality in the audio industry.

The problem is that because Huaguo Company is not very good for intellectual property rights, now BBESound basically does not authorize Huaguo Company, to put it bluntly, the "predecessors" are not good!

Moreover, for Polestar Electronics now, this standard is a bit difficult and there is no time to do it!

Xia Yu didn't know these things, in his impression, although only iAudio had exclusive BBE sound products at the beginning, but it should have been used by domestic MP3 brands in less than two years, so he wanted to try it on such a "whim".

Yang Chunsheng was also helpless, since he couldn't get it now, he couldn't hang himself here, so after explaining the situation to Xia Yu, the R&D department also began to contact the SRS sound effect.

That's it, in 2004, it was basically the first domestic manufacturer.

Fortunately, the progress here is quite smooth, at least I have been contacted and got the test control module, and I can do it first. Coupled with the previous work progress of Song Xiaogang's team, the research and development of Polaris K2 can be said to be eighty percent completed.

Another weekend, Xia Yu came to the company's first R&D department.

Now there is a conference room specially modified for the R&D department, and there are more than 20 square meters, and seven or eight people are just crowded together with various computers and computers.

Xia Yu pushed open the door, and sure enough, it was scattered, and even Yang Chunsheng was buried in a pile of materials to work. He couldn't help but say, "It turns out that everyone's working conditions are so difficult!"

Song Xiaogang was closest to the door, and was debugging an instrument at this time, and when he saw Xia Yu coming, he said: "Mr. Xia, you are finally here! This place is enough, the key is that there are a lot of things waiting for you to make a final decision!"

Yang Chunsheng also smiled and said: "This office is not much more than a beacon!"

"Don't worry, you can't say anything to our R&D department, and we will definitely arrange the best studio for you in the future!"

"Okay, Mr. Xia's words count, everyone is looking forward to it!" Yang Chunsheng quipped.

"No problem!"

The two packed up the materials and followed Xia Yu into his office.

After a while, Zhang Mei poured water recently, Xia Yu remembered that she was studying, and asked, "Zhang Mei, how are you studying lately?"

Zhang Mei blushed and whispered: "I enrolled in the class to study administrative management, only to find that there are so many simple things behind it, and it should be more difficult than you to learn......

Xia Yu just picked up the tea, and almost squirted out when he heard this!

An administrative management course taught by a teacher can be more difficult than a course in the third year of high school, which is funny! But before she could say this, Zhang Mei also chuckled and went out.

Xia Yu is most concerned about the sound effect, after all, Song Xiaogang has been reporting other things before, or Yang Chunsheng said first: "I'll report first." I've emailed BBESound on behalf of Polestar Electronics and called to ask for advice, but I haven't answered clearly. In fact, in the past few days, the effect of SRS is quite good. ”

"Oh, have you tried it? How do I remember that SRS is nothing more than a cosmetic sound?"

Modified sound effects, on the basis of the original music, are processed with spatial surrounding, sound field broadening, dynamic enhancement, etc., and the effects will indeed be rich, but Xia Yu remembers that he seems to have seen it somewhere, and this kind of sound effect does not help to improve the quality of music.

In fact, most smartphones in the market basically come with SRS audio effects.

There is also a reductive sound effect, which can be reasonably and effectively corrected and compensated for the distortion of the audio signal in the process of conversion, transmission, amplification and playback, so that the listening effect is closer to the "original" effect. In this regard, Dolby noise reduction and BBE are representatives.

"Mr. Xia!" Song Xiaogang called out first, "What is it called, it's just a decorative sound effect, and this thing is not something that ordinary people can play with, we worked on it for a few days to barely make a basic adaptation version!"

Xia Yu didn't really understand it, and he didn't check the information carefully, so he hurriedly said: "Ah, what's going on! I don't understand, Brother Yang, tell me!"

Yang Chunsheng smiled, is this normal, at this age, you know everything, it's not a monster!

He took out a piece of information and handed it to Xia Yu, saying, "In general, compared with BBE, the effect of SRS is indeed worse. However, there are many types of SRS, and it has developed quite well over the years. Besides, the sound quality of Polestar's MP3 itself is very good, and no matter how much it is improved, the effect will not change substantially. ”

Xia Yu carefully flipped through this information, only to find that SRS things are not so simple, there are more than a dozen classifications of different technical evolution versions and effects, and there are several suitable for MP3 use.

Historically, it was not until May 2005 that the domestic chip manufacturer Juli negotiated with the American SRSLabs company and formally signed a technology licensing agreement, so far China's first MP3 main control chip with SRSWOW sound - PMA300 was born, and it took a few months before it was officially listed, and there were more MP3s with SRS sound on the market.

The digital electronics market is like this, a lot of things can happen in a year, so like the Internet, only fast and not broken that is a secret.

Because Xia Yu didn't pay much attention to these at this time in his previous life, I just remember that Meizu's classic X2 is equipped with SRS virtual surround soundMP3, or released in January 2005, now think about it, it seems that Meizu's X2 really seems to be the first SRS sound MP3 in China.

It is precisely because of this that Meizu has continued to take off on the basis of X1, and has truly broken into the first-line camp of domestic MP3 in just two years.

There are still two months left, so has Meizu already started to contact the SRS room? This Huang Zhang is really not an ordinary person!

Thinking of this, he hurriedly asked, "Then have we made contact with the SRS room?"

Yang Chunsheng nodded and said, "After being blocked from the BBE side, I will start this." It was also introduced by a friend who used to make a DVD player, and now I have communicated with the people in the SRS real yàn room a few times, but they are tight-lipped, and the specific licensing fee is not mentioned, but they still gave us a set of plans to test first. ”

These guys are all profiteers!

Well, this is just a normal business, it is normal to sell at a price, and it is estimated that it will have to be resolved through negotiation later.

Fortunately, compared to BBESound, SRS still has a bit of trust in China, thanks to the predecessors who made VCDs and DVDs in the early years, and they didn't do things too well. And they are also operating as a corporatization now, and they are even listed on the NASDAQ, as if the stock price is not bad.

Yang Chunsheng said: "In fact, the SRS sound effect is more mature, and the main control chip of Philips can also be directly added in, which is much simpler in terms of adaptation, but the price is also much more expensive than its own independent licensing." ”

Xia Yu nodded: "Hey, if you really can't talk to Philips again, in order to grab this soup, it's okay to suffer a loss." But let's still focus on licensing, and then it's hard Brother Yang, with our components and solutions, to get this sound effect right. ”

"That's no problem, I'll spend two more days here at most, and strive to research out more things, and then I will have the confidence to negotiate with the SRS room." ”

Yang Chunsheng replied, thinking in his heart, it is more suitable for him to study and work in the real room, and the negotiation and competition in the shopping mall are too tiring.
