Chapter 63 is difficult, you'd better be mentally prepared (three more, one more arrives)

There is a very strange phenomenon in the domestic walkman market, on the one hand, there are cheap domestic products, the price of the Walkman without recording function ranges from fifty or sixty yuan to seventy or eighty yuan, the price of the walkman with recording function ranges from more than 1oo to about 2oo yuan, and the price of the high-end tape walkman imported from Japan is almost all concentrated in more than 8oo yuan, and the low-grade ones are mostly concentrated between 4oo and less than 8oo yuan, and there are only two or three models below 4oo yuan, as for the sound quality, don't mention it.

Lin Zheng is very curious, if China can produce an imported machine that is not inferior to about 2ooo yuan in terms of appearance and performance, and the price is about 5ooo yuan, will there be no market?

Regarding the cost of electronic products, Lin Zheng knows too well: this thing is profiteering!

After trying to disassemble a Sony M-EX1 priced at more than 4ooo, Lin Zheng was disappointed that the hardware cost of this machine, which is known as a sound quality artifact, will not exceed 6oo yuan...... This is already the top-of-the-line model and configuration in Sony's range of single players.

"We have also considered what you said, and with this strategy of Tian Ji horse racing, there should indeed be a considerable market space," Kong Xiaoming sighed, with indescribable disappointment in his words, "But this plan was rejected by our leaders." ”

"No? Why? ”

Lin Zheng and Tan Na glanced at each other, and in addition to surprise, there was more happiness in their eyes.

"Our leaders think that even if we produce this kind of Walkman, not to mention the cost and profit, the market will not be able to accept a Panda tape Walkman for four or five hundred or even five or six hundred, so you see, there is no Panda Tape Walkman on the market now There is no 1oo," Kong Xiaoming hesitated, thinking that Lin Zheng and Tan Na were really good to him, and he still persuaded him euphemistically, "But...... Mr. Lin, Miss Tan, I tell you the truth, and I also think that our leader's statement still has some truth, and your approach is ......."

"Some adventures?"

"That's right, it's a bit risky," Kong Xiaoming breathed a sigh of relief, he was still hesitating what to say, since the other party had recognized this problem, it was easy to say. Looking at Lin Zheng and Tan Na seriously, "I don't know what price your company is going to sell in the market, but since your company uses these models as samples, it is estimated that the cheapest will not be lower than 4oo, can you accept a 4oo~~5oo domestic high-end walkman ...... on the market?"

He shook his head and showed that he was not optimistic, but Lin Zheng was his "customer" after all, and he took out a large amount of "consulting fees", he was embarrassed to say these words, so he had to shake his head and bring the topic to the other side, "Production is a problem, there is no way to provide such high-precision production lines and molds in China, these need to be purchased, and patents are also a problem......

"Patents are indeed a trouble," listening to Kong Xiaoming's chatter here, Lin Zheng somewhat understood why Kong Xiaoming was so unwilling, Lin Zheng nodded and said, I don't know if he forgot or deliberately didn't mention it, Lin Zheng directly ignored the trouble of the production line and mold, "But ...... There's always a way to solve any problem, isn't it? After all, such as decoding chips, power management chips, buffer chips, etc., these are all standard parts produced by international manufacturers, and circuit design is one of the difficulties, but the most important thing is the writing of the code. ”

"This is the hardest part," Kong Xiaoming sighed, and suddenly his eyes widened, and his eyes were full of disbelief, "Mr. Lin has ...... Way? ”

He didn't dare to think that Lin Zheng actually understood the writing of these special chip codes, as for the decompilation of the code inside? He didn't even dare to think about it.

"Hehe......" Lin Zheng smiled and said nothing.

Kong Xiaoming also realized that his question was a little abrupt, and he was a little embarrassed, so he quickly changed the topic, "Mr. Lin, General Manager Tan, let me tell you this, I have no problem with circuit analysis and design, and I can help with this part of management, but since you are planning to make small household appliances, I am not good at power management and tuning, since you plan to get involved in this industry, you should know that it is not difficult to design a Walkman, but if you want to design a good Walkman, this is by no means a job that I can complete alone." I hope you two are mentally prepared for this. ”

"We know." Lin Zheng nodded, of course he knew that an excellent industrial product could not be done by just a senior electronic engineer.

"In addition, for portable audio-visual products, the front is actually fine, I personally think that the most difficult point is to tune out an ideal sound quality, how to render the sound quality, rendering the process is the most important, since your ideals are ambitious, then I propose yì in this area you must ask a master to help you deal with it."

Lin Zheng nodded again, "Thank you." ”

Although Comrade Lao Kong is a little verbose, but he is also telling the truth, of course he knows the importance of tuning in the design of the Walkman, Walkman, as the name suggests, that is used to "listen", not to "see", whether it can please the ear is the first element, not to say that when listening to this thing, a lot of time is on the road, so much background noise does not need too good sound quality and tuning, don't forget jì, there is a lot of time on the road to listen to the Walkman at the same time, there are also many people like to listen to it in bed at nightAt that time, there was not much background noise, at this moment, a Walkman was good and bad, and the ears were too powerful, and the sound source, playback equipment, and headphones were equally important and indispensable.

With a reference object, Kong Xiaoming's workload has been reduced a lot, and the entire process of analysis, circuit design and revision takes about a month, for the convenience of Kong Xiaoming's work, Lin Zheng even specially purchased a set of special equipment for Kong Xiaoming, but even so, Kong Xiaoming's workload is not light.

It's very depressing to say, all the integrated circuit chips in these cassette walkmans are all produced by Toshiba, Mitsubishi, NEC and other companies, Lin Zheng is too clear about the temperament of Little Japan, if he dares to use something from Little Japan, he will be stuck in the future, and he has no choice but to let Kong Xiaoming choose similar chips from Europe and the United States, if not, in fact, this time will not take a week.

"This is our design requirement," very understanding the difficulties of the technicians of this era, Lin Zheng and Tan Na handed over the design requirements of more than a dozen pages to Kong Xiaoming, and at the same time, they took out 8oo yuan and put it on the table, "This work is very brain-consuming, this is the nutrition fee that our company gives to the hole workers, you must not be polite." ”
