Countercurrent 1982

Chapter 542 Car Radio

The establishment of an office in Xiamen is an important step for Duan Yun's future layout in the south. This is just the beginning. Cities set up more offices.

After completing the formalities for Zhao Changfeng, Duan Yun came to the workshop again.

The installation of the test platform went smoothly, and all the circuits had been installed in place by the time we got off work in the afternoon.

After turning on the power, Duan Yun pressed the start button, and with the extremely fast rotation of the motor, the entire test platform began to run smoothly.

Duan Yun’s gearbox test platform can be used manually or automatically. Manual driving is no different from normal driving, except that you can’t feel the speed and direction of the car. It’s no problem to train ordinary drivers to get started.

In terms of automatic gear shifting, Duan Yun’s platform can set the gear shifting time, and can shift gears five or six times within one minute. Accessories for measuring temperature, noise and vibration are also installed around the tested gearbox. Once the car gearbox vibrates violently or the temperature is too high, it will automatically stop to ensure the safety of the entire testing process.

Duan Yun worked overtime at night, and Duan Yun was busy until almost 8 o’clock before returning home. Duan Yun was very satisfied with the results of the entire platform test. With this platform, Duan Yun will be efficient and safe when testing new gearboxes in the future. a lot.

After the successful development of the gearbox test platform, Duan Yu can finally breathe a sigh of relief and live a few days of easy life.

From the time when the factory built the factory to the development of the new Longteng gearbox, Duan Yun has been working overtime in the factory, but he has to be busy because of the tight tasks. Now, as the new products have been sent to BJ to participate The national quality appraisal, the heavy mountain on Duan Yun's body was finally lifted, the rest is to wait for the result of the national quality appraisal, usually only need to go to the factory to supervise the production.

The important tasks on the factory side have temporarily come to an end, and Duan Yun can finally free up his hands to prepare for his own electronics factory.

Regarding the business license for the electronics factory, Duan Yun needs to wait until the end of the year to give gifts to the relationship, which will take some time.

What Duan Yun wants to do now is to develop the main products of the electronics factory in advance.

In fact, Duan Yun Workshop has been assembling and producing subwoofer speakers at present. This kind of speakers is still very good in terms of sales in the Daxing market, and it has also accumulated a lot of funds for Duan Yun.

Now after several months, Duan Yun already has nearly 30 yuan in hand, which is enough for him to start a small electronics factory.

With the funds to set up a factory, Duan Yun will start to design the flagship products in advance. In addition to subwoofer speakers, Duan Yun also plans to focus on car audio.

The reason why he chose car audio as the future product of his electronics factory is because Duan Yun currently has many contacts with car factories. His future product sales and contacts will be centered around the car industry, while car audio radios Basically, it is the standard configuration of all cars. Duan Yun has advantages in developing this product, both in terms of technology and future sales.

Another point is Duan Yun's research and development of car radios. The ultimate goal is to take advantage of the localization of Santana Motors. Santana Motors has high technical content in other parts and components, and domestic production is difficult. Only this car radio can be counted. It is the easiest breakthrough for the localization of Santana cars.

In fact, since October 1984, when China and Germany each contributed 10% to establish Shanghai Volkswagen Co., Ltd., the country has always put the localization of Santana cars as an important matter on the agenda, but until 50, The localization rate of Santana has been unable to increase. Only tires, radio antennas and signs are the "big four", and the rest must be imported.

Before 1987, the antenna and radio of the Santana car could be localized, indicating that the quality of domestic electronic technology components can meet the requirements of the Santana car. The main product of the factory, and once it can become the designated supplier of the Santana car radio, then Duan Yun's electronics factory will receive stable and large product orders for at least ten years or even longer.

However, developing car radios is not an easy task. Compared with ordinary radios, car radios are exquisite in workmanship, and their power is much larger than that of ordinary home radios. Generally, the power of home radios is about 50 milliwatts to one watt. Radios are generally above 5 watts and have high fidelity.

It is also because the power is higher than that of ordinary household radios, so the car radio can receive some stations that cannot be received by household radios, the signal fidelity is high, and the sound quality is also very good.

Duan Yun had experience in improving radio antennas and speakers before. Logically speaking, designing a car radio is not a difficult task. A series of problems such as changes in the strength of the received signal must be resolved.

Duan Yun has never been in contact with car radios before, so if he wants to design and manufacture this kind of product, he must first find some suitable samples for reference.

At present, there are very few local cars in Daxing, and ordinary trucks do not have car radios at all. Even long-distance truck drivers only carry a home radio with them, but that is not a special car radio. There is a big difference between the two .

If Duan Yun wants to get a sample of the car radio, he can only go to the Daxing Automobile Factory again. The types of vehicles produced there include some slightly more advanced cars, which should be equipped with car audio.

In the early morning of the second day, Duan Yun drove to the Daxing Automobile Factory.

The factory director Li Xiu inspected the production in the workshop, and he was received by the deputy factory director Wang Baoguo.

Nowadays, Duan Yun has a good personal relationship with the main leaders of Daxing Automobile Factory. In private, Duan Yun asked Cao Dong to send each of them a set of antennas and speakers for "trial use". It is just for the convenience of Duan Yun when he takes orders in the future.

After learning about Duan Yun's intentions, Wang Baoguo took him to the trolley class.

In the corner of the garage, there is a Shanghai brand car parked. This is a car specially purchased by Daxing Automobile Factory to study the production technology of Shanghai Automobile Factory. Some internal assembly parts of the car have been disassembled There are only 4 tires and a casing left.

However, when Wang Baoguo opened the door of that car, Duan Yun saw the car radio embedded in the passenger seat at a glance.
