Fan Wubing clearly remembers that the machine he got in the first year of junior high school spent seven or eight years with him, and was still in use in college, and the effect was also good.

He also remembered that in order to find a plate of song belts, he braved the rain and searched around the streets to bargain with the stall owner. A plate of ten yuan can often be sold for six or seven yuan. Although I don’t know if it is genuine or pirated, the effect is really good.

Since Walkman can last for more than ten years, why can't we do this?

Fan Wubing slowly unfolded a circuit structure diagram in front of his father Fan Heng.

"Great Father, do you see what this is?" Fan Wubing asked with a smile.

"When did you learn to be slick?" Fan Heng blamed him very slowly, and then looked at the circuit structure diagram carefully.

Fan Heng was promoted from a technician. It was no problem to look at the circuit diagram. After all, the high-end technology is also high-end technology. If you can't even understand such a simple circuit diagram, you'll have lived in vain for decades.

"This thing looks a bit like the circuit diagram of a radio, but it's not the same. You can't say that this thing is the circuit diagram of this Walkman, right?" Fan Heng asked hesitated.

"Congratulations to dad, the answer is completely correct." Fan Wubing nodded with certainty.

"But there are several key components here, I don't understand it very well." Fan Heng then pointed out several places on the picture.

Fan Wubing looked at it and found that his father pointed out that the key technologies of Sony, such as magnetic heads and integrated control circuits, and then replied, "This is normal. The company is counting on these places for dinner, and other things do not have a high technical content."

"What does it mean when you let me see this thing?" Fan Heng felt that his son must have some idea.

"Don't your factory convert most of its production capacity into private goods? How do you think of this thing? Can it be done?" Fan Wubing didn't feel anything. Anyway, he was in his own home and was facing his father, so he naturally said whatever he said.

"We are not doing this! If this is a radio plant, it's just right. It's hard to say that it's here, and it may not agree with it-" Fan Heng looked at the circuit diagram, frowned, and hesitated for a moment.

Fan Wubing rolled his eyes and thought to himself that there are so many of you! You are asking your army to move and the people to take care of your own. How can you do it without showing some courage when doing big things?

In fact, the thing Sony created is simple. The key technical parts are: one is that the quality of the magnetic head is high, and the other is that the integration of the control circuit needs to reach a certain level. Other housing speakers and stepper motors have very simple structures. For example, a factory in Pingyuan Factory that is engaged in military production, there should be no problem in doing this kind of thing.

Fan Heng obviously understood this. He held a walkman on the table that had been removed by Fan Wubing in his hand for a while and came to the same conclusion as his son, "If the problem of the magnetic head and control circuit is solved, everything else will be easy to deal with, and the existing equipment in our factory can be solved by itself. If you want to form a large-scale production, it will take about three months to half a year to complete it."

"So fast?!" Fan Wubing felt a little incredible.

In fact, he didn't expect that an old factory like Pingyuan Factory would have a single product, but the technical workers had a solid foundation. There were no complicated equipment except for the head and control circuit of the Walkman. Once these two problems were solved, it was very slow to form productivity in three months.

"However, I seem to remember that the country has regulations on this aspect. If you want to produce recording equipment, you must obtain approval from the superior department and register with the local public security organs. This procedure is very troublesome. Don't say that this machine is not easy to make, even if you can make this machine, sales license is a big problem and the buyer is also a problem." Fan Heng's words poured cold water on Fan Wubing.

How could there be such a brain-dead rule? Fan Wubing suddenly became depressed.

In fact, even in the economically developed city of Shanghai, before the 1980s, only a few big figures needed by the united front could have recording equipment in their homes. Ordinary people would not see it, let alone that the public security department would approve you to put one at home.

Perhaps, this regulation is also due to safety considerations, but in Fan Wubing's opinion, it is really a bit ignorant.

Did he just give up like this? Fan Wubing thought about it and felt very unwilling to accept it. This is a great project that can support a factory of such a scale in the Plain Factory for more than ten years. Where can I find such an easy project?

"As long as it is a production recording equipment, it must be registered by the public security department and licensed before it can be produced and used?" Fan Wubing was still a little unwilling to give up.

Fan Heng nodded, "I happened to know about this. The opening machine of our factory department was registered with the public security department. I heard from the stationmaster Wu of the factory department's radio station."

"Website Manager Wu? Is the pretty and nice aunt at the radio station who speaks very well?" Fan Wubing immediately raised his ears and looked at Fan Heng with a bright look, with an evil smile on the corner of his mouth.

Fan Wubing knew about Webmaster Wu. This woman was only twenty-seven or eight years old, she was quite beautiful, and her voice was sweet. The union in the factory often asked her to host events, and she was considered a popular lover of Pingyuan Factory. Later, after Pingyuan Factory had its own cable TV station, she became the first director and worked for more than ten years.

"Go and go! Don't think about it all the time if you're okay! How old is the person, why are there so many messy things in his head?" Fan Heng saw Fan Wubing's evil smile, how could he not know what he was thinking, and he was immediately angry and embarrassed.

After laughing for a long time, Fan Wubing suddenly came up with a compromise idea and said to Fan Heng, "I suddenly thought of a solution. Otherwise, let's cooperate!"

"Let's cooperate? I'll be with you?" Fan Heng suddenly felt a little incredible.
