After Duan Yun and Zhao Changfeng chatted for a while, the two of them returned to the dormitory to rest.

Everyone slept until noon on the second day, and after having lunch together, they began to carry out the final commissioning of the production line, and part of the equipment of the production line was moved to the clean room, and the interior was carefully cleaned and cleaned.

Set up a new production line. There are a lot of details that need to be developed and processed, including the production regulations on the workshop, as well as the training of employees, which will take some time.

Duan Yun this time specifically put the equipment for the production of motors in an independent workshop, in Duan Yun's view, the introduction of the Japanese second-hand production line is the most valuable is this set of equipment for the production of motors, the use of high-performance chips and several retired professors for part of the military technology modification, this set of equipment produced by the motor performance is very good, not only low price, but also in terms of overall performance, but also much stronger than the tape recorder motor produced by other factories in China, which is a very competitive product.

Because of this, Duan Yun took this kind of motor equipment as the core technology, and specially drew a closed small workshop in the large workshop, in order to avoid technical leakage, he only trained a few workers with a high level of education but hard-working to operate, they only know how to use the machine, but they do not know the design principle of this machine.

In addition to the motor, Peng Changming only took two days to make the rosin printing plate and tin pot, and it perfectly fit with the plug-in machine to form a complete circuit board processing line.

May 8th was a day of great significance for Duan Yun, on this day, the first small tape recorder produced by their factory was assembled, and after passing the quality inspection, it successfully walked off the production line.

Compared with other tape recorder products on the market, the appearance of this small tape recorder produced by Duan Yun is very novel, not the traditional square shape, the corners are full of arcs, the appearance has red, silver gray, and black three colors, and the portable part is also semi-arc, very fashionable, and full of science and technology.

In addition, this recorder is much lighter than other tape recorders on the market, the two speakers can be split, and a single motor drives dual cards, which also greatly reduces the cost and gives people a refreshing feeling.

In fact, the sound effect of this tape recorder designed by Duan Yun is not as good as that of the traditional tape recorder of the large one, but in fact, for ordinary people, this subtle difference in sound quality is difficult for ordinary people to distinguish, and in order to increase the acoustic shock effect of this tape recorder, Duan Yun also transplanted the technology of his Tianyin brand subwoofer audio to this tape recorder, so that when this tape recorder plays rock music, the sound effect is much more shocking than that of ordinary tape recorders.

When the wolf disco released from the first new tape recorder resounded throughout the workshop, everyone on the scene applauded excitedly, and the corners of Zhao Xuewu and others were a little moist.

There is no doubt that no matter in terms of cost or technology, the new tape recorder produced by Duan Yun has a strong competitiveness in the domestic market, although it cannot be compared with the latest foreign tape recorders, but at least this product is already a very avant-garde product in China.

At noon, the canteen of the electronics factory was full of people, Duan Yun added him to all the employees, each employee provided half a stewed fish for free, and a bowl of braised pork, and in the private room of the canteen, Duan Yun and all the technicians of the institute sat around and drank wine to celebrate.

"Thank you, I would like to thank you all on behalf of my husband and the company. At this time, Cheng Qingyan poured a full bottle of wine for the retired professors with a smile on her face, picked up her wine glass and said sincerely.

Cheng Qingyan was very surprised to be able to complete the production line so quickly and make a new high-quality and low-cost tape recorder, so at this moment she was also in an indescribable excitement.

In fact, Cheng Qingyan never thought that her husband could really make such a high-quality new product so quickly, after all, she was also a person who was engaged in technology before, and knew the difficulty of developing new products like tape recorders, especially the competitors are those old state-owned factories that have accumulated more than ten years of technical experience in the research and development of tape recorder products, so all along, seeing her husband spending money like dirt, desperately spending money to buy equipment, and hiring talents with high salaries, in his opinion, this is a bottomless pit, and it is likely to be lost, but after all, the company is Duan Yun's, and she can only support it as a wife, but she still has deep doubts about her husband's approach in her heart。

But now it seems that her husband has created a miracle again, which makes Cheng Qingyan feel shocked in her heart, and at the same time, she can't help but breathe a sigh of relief.

"Come on, come and raise your glass!" Zhao Xuewu also seemed very excited at this time, and the first one picked up the wine glass and stood up.

Seeing this, the others also raised their glasses and stood up.

In fact, these old professors are too old to drink, and they usually don't drink at all, but on such an occasion, everyone is very excited and excited, and they don't mind occasionally sacrificing their lives to accompany the gentleman.

In addition to Duan Yun and his wife, as well as the five professors of the institute, including Li Guosheng and his wife, Zhao Changfeng, and the two tigers of the army, they also talked about the development of the company and their vision for the future.

The tape recorder that first came off the assembly line was placed in the private room, and in fact, the army had a dance music tape in it.

A soft dance music sounded in the private room instantly, and Duan Yun, who had already drunk a lot of wine and was slightly drunk, glanced at his wife sitting next to him, and on a whim, he bowed to Cheng Qingyan very gentlemanly and signaled to dance with her.

At this time, Cheng Qingyan also drank a lot of wine, her pretty face was a little red, and today she was also carefully dressed up, wearing a small red dress, with golden earrings, and the diamond ring on her finger was shining, which made her more beautiful and moving.

Although the two have been married for more than half a year, seeing her husband suddenly invite her to dance on this occasion, Cheng Qingyan's face still flashed a faint shyness, and under the cheers of the two apprentices of Dajun Erhu, the hands of the two finally held together.

The dance music was soft and soothing, Duan Yun seemed to have returned to the moment when he invited Cheng Qingyan to dance for the first time in the factory air defense dance hall, looking at his wife's delicate and somewhat rosy face, Duan Yun's heartbeat suddenly accelerated, and the two of them walked on the dance floor, swaying gently and dancing.

Hugging his wife and making a new breakthrough in the career he wants, Duan Yun has an indescribable sweetness and vigor in his heart......
