This seminar on the design of new tape recorder products is very important, and it can be said that it is related to the future life and death of Duanyun Electronics Factory, so it must be repeatedly scrutinized on the design issue, and there can be no mistakes.

After Duan Yun introduced this production line, he began to focus on the development of its international tape recorders and conducted an in-depth analysis.

In fact, in Duan Yun's long-term plan, the production of tape recorders is only a transitional process, and he still wants to produce pocket digital electronic products such as Walkmans, CD Walkmans, and video recorders in the future, and the production of tape recorders is just to avoid idle production lines before the Walkman products are produced.

Because in Duan Yun's view, the domestic tape recorder market has been very competitive, manufacturers are reducing prices with each other, the profits are very meager, and the dividends of tape recorder products are at most one or two years, and when the household appliance fever ebbs around 87 and 88 years, this product will face market shrinkage and serious unsalable, so there is only a 1~2 year bonus period.

However, although it is a transitional stage of the product, but this stage is equally important, Duan Yun can use the research and development of tape recorder products to exercise his own product research team, and there will be a certain amount of accumulation in technology, and when the team accumulates technology to a certain extent, it will be much easier to develop and produce Walkman products.

After hearing Duan Yun's technical requirements for new products, everyone present suddenly became grim.

These 5 retired professors are not engaged in research and development work for the first time, they have all participated in product research and development in the military field before, although the technical requirements put forward by Duan Yun at this time are relatively light, but in fact it is very difficult to meet his technical requirements, after all, other domestic tape recorder factories are not dry, some electronics factories have been immersed in the tape recorder for many years, rich experience, strong technical accumulation, want to surpass these domestic counterparts in a short period of time, it is not an easy thing.

“...... At present, most of our domestic four-speaker high-end domestic tape recorders are priced at about 500~700 yuan, and the Sharp tape recorders imported from Japan are 8,000~About 1300 yuan, take the most well-known Yanwu tape recorder factory products in China, they can reduce the price of dual card 4 speaker tape recorders to about 400 yuan, almost compressing the cost to the extreme, so when we develop new products, we must strictly control the cost of products, price is competitiveness, there is no price advantage, our things are not easy to sell. When Duan Yun said this, his face was a little grim.

At present, the competition in the domestic tape recorder market is quite fierce, and the old tape recorder electronics factories, such as Shanghai Electronics Factory No. 1 and Shanghai Electronics Factory No. 2, can be said to be the best quality in China, and Yanwu tape recorder is the cheapest.

In order to reduce the price, the Yanwu tape recorder factory has made a hard rule on the technical personnel of the research and development products, the lowest price of smoke products and similar price products in the market is the cost design, in the cost design process, each reduction in the design cost of one yuan, reward the designer 300 yuan, on the contrary, if more than one yuan, the fine is 300 yuan.

It is by virtue of this strong reward and punishment system that Yanwu Electronics Factory has made the most affordable tape recorder products in China, with the popularity of various advertisements, so that they have become the strongest domestic tape recorder brand in the mid-80s, and in 1987, it achieved a total industrial output value of 252 million yuan, profits and taxes of 38.8 million, and is one of the country's 100 key enterprises.

"Manager Duan, I think the current design principle of the tape recorder has basically been fixed, it is not easy for us to make a breakthrough in technology to reduce costs, unless there are cheap raw material supply channels, otherwise if you want to make the same products as other manufacturers, the cost cannot drop too much...... "Zhao Xuewu also said with his hand on his glasses at this time.

Zhao Xuewu has also been studying the development of the domestic tape recorder industry during this time, and asked for a scientific research fund through Duan Yun, and first bought a batch of the latest domestic tape recorder products after getting the money.

"Yes, some time ago we have been in the research institute to dismantle and analyze the products of other domestic manufacturers, basically all the manufacturers' products are similar, the process is slightly different, but the electronic parts used are basically the same, two of them are imported from abroad magnetic head movement and other parts, the quality of this product is good, but the price is relatively high, some factories simply replace with cheap domestic parts, the price is down, but the quality is very inferior, it sounds noisy, it is really a penny for a penny, want to make high-quality products, it is difficult to reduce the cost......" Yang Xiuchun also frowned and said.

Like Zhao Xuewu, Yang Xiuchun is also a well-known electronic expert in China after all, and she has been dismantling and analyzing other domestic tape recorder products with several other professors in the past two days, and she also has a certain understanding of the technology and design of domestic tape recorder products.

"I know that it is difficult to reduce the cost of tape recorder products, but this is the key problem for our electronics factory to break the game, so we must balance the relationship between quality and cost to reduce the price of products. Duan Yun pondered for a moment, and then said: "Actually, I can provide you with an idea of reducing the cost of products......

"What idea?" several people present asked one after another.

"The last time I went to Japan to test him, I visited the factory in Japan, and the new product of the dual-card movement tape recorder produced by their factory this year uses a structure of one motor to drive two drive mechanisms, and the current motor cost of the domestic tape recorder can account for about 1/3 of the entire tape recorder, so if you can make a single-motor driven tape recorder, then the cost can be greatly reduced...... Duan Yun raised his eyebrows and said.

"Single-motor drive tape recorder ......" Hearing this, several people present suddenly showed incredible looks.

For technicians who know a little about the construction of the recording machine, the single-motor driven tape recorder technology has not yet appeared in China, and the technical difficulty is very large.

Generally speaking, now the household cassette tape recorder is the use of multiple heads and multi-motor structure, most of them use three heads that are recording, the head playback, the head and the end of the sound head, there are also 40 heads, the motor is the use of two or three or even 4 or 5, such as a suitable tape recorder produced by a Japanese company called Ak ai, it uses 4 heads and 5 motors, the mechanical transmission is extremely energetic, and the speed of fast rolling in time is only half of the general tape recorder.

The single motor drive puts forward higher requirements for the motor, because the replication of the whole machine, the two-speed copy, the automatic selection of fast forward and fast backward and the function of automatic return all need to be driven by the motor, and the technical difficulty is still very high.
