For Duan Yun, no matter what kind of integrated circuits this high can bring in the future, as long as it can be used, it will be very valuable to Duan Yun.

With these integrated circuits, Duan Yun can design more powerful 'black technology' products, which will be very useful for him to make various production equipment in the future.

It's just that Duan Yun also knows that now he can only rely on luck if he wants to buy a chip, and I hope this tall man can bring him more surprises in the future.

In general, Duan Yun has gained quite a lot from this small market of radio enthusiasts today, in addition to buying a precious chip, he has also found a channel to promote his electronic products in the future, and it can be regarded as discovering a 'new continent' full of vitality.

After leaving the fourth archway, Duan Yun waited at the gate of the roller skating rink for Cheng Qingyan and the others to come out, and then returned to the factory together.

The young men and women who came with them today were obviously very happy, talking and laughing along the way, and the atmosphere was very cheerful.

For Duan Yun, organizing such activities often is also conducive to improving the morale of his team, and in Duan Yun's opinion, if Cui Lin Leizi and his gang can seize the opportunity to talk about an object or something, it will reduce the chance that they will have nothing to do and fight and make trouble when they are idle, and the cost of having an object will also increase, and if they want to make more money, they will have more motivation to work.

On the way, several pairs of men and women have begun to look at each other, and they obviously have their own favorite goals.

It is estimated that if Duan Yun comes to such a group activity a few more times, he will definitely be able to produce a few little couples.

After returning to the factory, it was already evening, and the factory was full of people, and the people on both sides were immediately divided into two roads.

"Brother Duan, can we come out again next week?" Cui Lin asked Duan Yun with an expectant look after seeing Cheng Qingyan's female workers separate.

"As long as my brothers work hard next week, we will continue to organize activities next Sunday. Duan Yun paused, and then said, "The weather has been a little hot recently, next time let's go swimming in Shuibo Temple." ”

"Swimming in Shuibo Temple?" several young workers suddenly perked up when they heard this.

Shuibo Temple is a reservoir located in the northern suburbs of Daxing, with a large area, and many local citizens come there to swim in the summer every summer.

"When the time comes, I will contact Cheng Qingyan and the other female workers again, and it would be better if we could go to play together. Duan Yun smiled slightly, and then said: "But our work here has to be stepped up, I hope that this week the brothers can work harder, and strive to make the antenna inventory reach five hundred sets!"

"No problem!"

As soon as Duan Yun's words fell, Cui Lin and Leizi and his gang happily agreed.

"Brother, the antennas have been sold less recently, and if you let the inventory of 500 sets of antennas work overtime a week, it will be okay, but the problem is that the inventory is too much......" Cao Dong said with a frown.

"I'm afraid I don't have enough of it. Duan Yun pursed his lips, and then said: "If you can't sell it, you will lose my money, you are worried about a fart." ”

"I'm worried about Brother Duan, you ......"

"Alright, do what you have to do, you don't have to worry about the rest. Duan Yun motioned for Cao Dong to shut up.

didn't work at night, and after Duan Yun and his party entered the factory, they went back to their respective homes.

Duan Yun returned to his studio first, and then put the circuit board he had just received today into an iron box and put it in the drawer of the desk.

For Duan Yun, this chip was not easy to come by, and he had to think carefully about a place that could come in handy......

......

In the next two days, Duan Yun's life was quite busy.

On Monday afternoon, Duan Yun went to Master Jing's house to see how his current speakers were doing.

Although Jing Zhiqian's house is small, the small house built downstairs is very large, with all kinds of wood and carpentry tools in it, which is obviously where he usually does carpentry work.

Duan Yun asked him to make a high-end speaker according to his own drawings, and Jing Zhiqian also spent some thought on this.

Because Daxing is located in the north, there are more poplars and elms, and there are many kinds of surrounding ravines and ravines, but the things made are different, and it is also a little particular to select suitable good wood.

The elm wood selected by Jing Zhiqian this time, the pattern of this wood is very beautiful, but there are many shortcomings, one is good for cracking, two is good for insects, and three is too many pimples.

Making speakers is naturally the part that needs the backbone, and in the treatment of wood, Jing Zhiqian also has his own very experienced experience.

According to his idea, the freshly cut elm wood was cut into more than eight to ten lengths according to the height of the box, and then placed in the room to dry.

Because elm wood is easy to attract insects, firewood is piled up in the fire room, and smoke rises behind the small stove, and the eggs of the insects will be killed every day.

It will take more than a year for the fire room to be left in the shade, but fortunately, there are still some spare elm materials that have been processed in the shade before Jing Zhiqian.

The good wood section is cut from the middle, two halves, and then processed into a wooden board, with a chisel cut down, the hammer Ding Ding when chopping and knocking, probably processed into a board shape and then the planer brush brush flat, it looks like the desktop is so flat after a closer look, there will always be a worm eye on the board, pick the place with many eyes to avoid, draw a suitable size of the place can be used.

Then the big saw is sawed open, and then a few planks can be put together into a three-dimensional long box.

In addition, there is still some oil and moisture in the freshly sawn plank that also needs to be forced out, Jing Zhiqian covered the wooden board with hot grass and wood ash, wrapped it and grabbed the pine needles and wood branches on the top, and the wooden board was protected from too hot by plant ash. After being scalded for six or seven days, the surface of the board will be slightly scorched, and the ash on the board will be dusted off, revealing a dark surface.

The glue used to bind the board is not ordinary glue, but boiled pig fat, which will freeze into lumps after a few days. The smell of this skew is a bit stinky, so it is also covered with paper and put in the ashes of the grass and wood in the vegetable cellar, which can be used for several years. When you use it, knock down the block, boil it for 4 hours, and then put it hot before you can use it.

Finally, there are some particularities in the grinding of the opening of the speaker and the varnish, which are necessary steps to make a sophisticated and durable speaker.

In comparison, the simple wooden speaker that Master Jing made for Duan Yun before was actually an inferior product that cut corners, if Duan Yun hadn't offered him such a high salary, Jing Zhiqian would not have been so attentive to making such a high-end speaker.

After Duan Yun learned about Jing Zhiqian's procedure for making speakers, he was also secretly surprised in his heart, he didn't expect a simple-looking speaker to be so complicated to make, fortunately, Master Jing has saved a lot of materials over the years, so he only needs to do some processing.

At the same time that Master Jing carefully made the speaker shell, Duan Yun also optimized the audio circuit again, and also bought two ten-inch loudspeakers through Li Caitou, and the first subwoofer was about to be born......
