"A motor of about one thousand watts?"

Zhao Qingshan and Lai Guigui looked at each other: "If this is to be mass-produced, it seems possible. What do you think, Lai Gong?"

Lai Baoguo thought about it carefully: "It should be no problem, but it is still a bit difficult to mass produce. It will take some time for Donghe Electric Machinery Factory to complete it."

The motors currently used by Weilai are all processed by Donghe Motor Factory.

They originally produced industrial motors, but now they are a bit busy making these automotive motors.

"Then you design a one-kilowatt motor first and let them tinker with it slowly."

Motor factories can now produce 300- to 500-watt motors, and it should not be too difficult to produce 1kw motors.

It's just that making molds takes a while, and it really can't be done by Weilai Mold Factory.

If Weilai Mold Factory doesn't have time, it's okay to ask Donghe Mold Factory to make molds for them.

After leaving the Electrical Research Institute, Jiang Yu arrived at the electronics factory within a few steps.

Compared with the bustle of people in other companies, the electronics factory is much quieter.

Although a prototype of the DVD player was made, because there was no disc inspection, it was not known whether the DVD player was qualified or not. Therefore, after more than a hundred units were produced, the production was temporarily suspended.

Only Zhang Chong and the scientific researchers are doing some scientific experiments in the factory now.

He is studying DVDs according to Jiang Yu's suggestions or prompts, but he hasn't gotten a clue yet.

A VCD player is connected to a set of old speakers and is playing CDs.

Today's VCD players can only be used as CD players.

"Mr. Jiang! When will the CD of this type be produced?"

"I have no say in this. After all, it is not our company, but don't worry. I estimate that it should be done no later than the 20th of this month."

"Hurry up and make it so you can test whether our DVD player works well. It's useless just to play CDs."

"Where did you get such a broken pair of speakers?"

"I installed it myself! I bought four three-inch speakers and two tweeters in the store, and then asked someone to nail a pair of boxes and made it."

"How did you connect the DVD player directly to the speakers to make it sound?"

"Who said it was directly connected to the speaker? Doesn't it also have an amplifier?" Zhang Chong pointed to the side of the speaker.

Only then did Jiang Yu see a wooden board placed next to the speaker. A circuit board was fixed on the wooden board, and some electronic components were soldered on it.

The signal output lines from the DVD player are connected to these electronic components, and then connected to the speakers.

Jiang Yu was also a semi-expert in home appliances, so he went over to look at the power amplifier made by Zhang Chong.

"You are a college student, you are so awesome! You just used these shabby components to make a power amplifier, and the sound sounds okay. Seriously, I will put a casing on this power amplifier and make it a proper one."

Face, I don’t dare to say that there are too many in the market, and it sells for five hundred yuan, inside and outside the pot.”

Jiang Yu could tell from this small amplifier that it would definitely not work for singing karaoke. After all, its transformer was too small. With the power of the transformer, it is estimated that the speaker would blow up when anyone screamed.

But playing a song or something at home is definitely enough.

"I just made it and played it to listen to it. Even if I really wanted to use it as a karaoke amplifier, I would have to replace it with a high-power transformer at the very least. This transformer won't work at all."

"The transformer is indeed a bit small, so I said it is only worth 500 yuan. If it is replaced with a larger transformer, it is still worth 1,500 yuan. If Dolby noise reduction surround is added, it will be worth 2,000 yuan."

"Mr. Jiang! You're kidding me. It's not worth that much money."

"Gong Zhang! Didn't you realize that the design of your power amplifier is very novel, the wiring is not complicated, and there are not many components used, but the sound transmission effect is really good. Are you interested in optimizing your power amplifier?"

"We want to produce amplifiers ourselves?"

"No! Let others produce it and I'll sell it for you. Why don't you sell it for tens of thousands of yuan?"

"real?"

"Of course it's true, but there's a prerequisite: you can't delay your work."

"That's no problem! I don't take it seriously when I do this thing. It's okay if I can think about it. It doesn't take much to optimize it. Just wait and see and fiddle with it."

Jiang Yu and Zhang Chong chatted about power amplifiers for a while, and then the topic shifted to DVD players.

"Mr. Jiang! If there is a VCD machine now, I mean the mass-produced VCD machine can be used as a reference, and the progress of researching DVDs can be much faster."

"Don't worry! The VCD machine will be ready soon."

In the west factory building of the agricultural four-wheel vehicle in Nanjianshan, Wei Junsheng is instructing employees to do the final debugging of the single-row wind turbine assembly line.

From stamping to welding to spraying to assembly, every process is meticulously inspected.

Jiang Yu came here after coming out of the electronics factory.

"Gong Wei! Can the single-row Fengling be offline at the end of the month?"

"Yes! Definitely!"

The single row of Feng Ling coming off the assembly line can alleviate the supply shortage problem of Feng Ling vehicles.

Jiang Yu knew that there should be many car manufacturers across the country dismantling and researching their Feng Ling. Once the research is almost complete, they should imitate it.

But he has no worries at all. He doesn't think domestic car manufacturers can keep up with them.

Jiang Yu came back from Songyang at dark time on June 4th, and it was already June 8th in a blink of an eye.

At two o'clock in the afternoon on the 8th, a Dongfeng 140 drove into Fengwobao Village. After some inquiries, the truck drove up Dongshan and entered the electronics factory.

After receiving the news, Jiang Yu quickly came to the electronics factory and shook hands with Liu Chuanming.

"Director Liu! I didn't expect you to come so quickly. I thought it would take half a month for you to come."

"Mr. Jiang! You said that no matter what, you would send a thousand microphones first. When I got back, I hurriedly made two thousand microphones and sent them to you."

The thousand microphones Jiang Yu wants are for the first batch of one thousand video disc players.

He is not in a hurry to get the others.

Jiang Yu called Zhang Chong over and asked him to randomly check the quality of these microphones.

Zhang Chong randomly picked out two microphones and opened the simple paper box.

"Your packaging needs to be changed. How can such a simple packaging work? It needs to be more exquisitely designed. If something is obviously worth 50 yuan, your packaging is worth 20 yuan."

It's just an ordinary white paper shell with no words printed on it.

The microphone is still wrapped in white paper. How can this be done?

"Isn't this urgent? It will be delivered as soon as it is ready."

"Go back and use a cardboard case, print a microphone on the outside, and use a plastic bag on the inside. It's best to make a small seat out of foam and embed the microphone in the small seat. Wouldn't it look classy like this?"

While Jiang Yu was teaching Liu Chuanming how to package products, Zhang Chong had already plugged the microphone into his improved amplifier.

After Jiang Yu told him about the power amplifier that day, he used his off-duty time to upgrade and improve the power amplifier.
