It's not just VCD and Walkman, now Su Jingzhen's factory is speeding up construction, and the chassis and power supply will be put into production one after another, but the publicity mode of these products is not the same as that of consumer electronics, and it is not suitable for large-scale publicity on a platform like TV, so Su Jingzhen didn't let go of his hands and feet.

In fact, the earliest product produced by the Su family's factory was not the Walkman, but the wires and cables purchased and produced by Su Guo in Zengcheng, and this small township-level factory that originally only produced low-end aluminum core wires was also upgraded by the industry and turned into a medium-grade production enterprise that can produce copper core wires and cables.

It will provide copper core power cord for all consumer electronics under the name of the Su family, this item alone, the cost of the Su family's electronic products has dropped by seven cents, don't underestimate the seven cents, every VCD, power strip, chassis power supply, mobile air conditioning and other products need such a power cord, one will save seven cents, if the product is bought more, the power cord alone can produce hundreds of thousands of profits, enough to maintain the daily office expenses of so many factories.

"Jingzhen, the noise problem of the mobile air conditioner has been solved, from 70 decibel before the renovation to 30 decibels, basically it will not affect the daily life, but I still feel a little buzzing when I sleep at night. "Cousin Yuan Guanghua took a plane to the imperial capital, and now it is Zhang Hong who is in charge of the production, and the chores that Yuan Guanghua was in charge of were carried by Su Quan.

"Huh, Dad, how did this be solved?" Su Jingzhen was a little curious, because this problem had been bothering everyone for a long time, why did it suddenly solve it?

"At first, we thought that the spring of the base was not working, which caused structural vibration, but after adjusting it, we found that although the noise had decreased, it was still far from comfortable.

So everyone was a little baffled, and finally a mainland engineer proposed a solution, directly changed the shape of the impeller's fan blades, and then the noise was basically solved. ”

Su Kuang's face is also very admirable, because at the beginning of the autopilot test run of the spare parts one by one, it was found that the noise of the fan was the most powerful, but it was not to the level of noise, but as soon as it was assembled, it was found that the noise was particularly large, which must be due to resonance, but what spare parts resonate with each other? This is more testing.

The engineers who developed the mobile air conditioner hated this product to the core, so they began to try how to disassemble and install, change the position of spare parts and other means, and designed several solutions for the internal structure alone, but failed to solve the noise problem.

Now that Su Jingzhen said this, Su Jingzhen understood a little, it turned out to be because of the shape of the leaf surface.

"What is the principle of this? Is it that the fan makes a sound as soon as it spins fast?" Su Jingzhen and Joanna have been redesigning the company's structure these days, and their minds are full of the company's articles of association, and now they are just listening to their father say something else, change their minds.

"It's not counting, one is the noise generated by the turbulent vortex brought up when the leaf surface rotates, and the other is the noise when the refrigeration compressor is running, these two are the main noise sources, we have solved the noise of the refrigeration compressor before, but there is no way for the fan. Su Guo sat in the office, drinking tea and saying, as soon as the noise problem of the mobile air conditioner is solved, trial production can be carried out, if the product test passes, then it can be deployed and listed, and there is one more industry at home, and he must be very happy in his heart.

"Then it's solved by replacing the leaf surface now?" Su Jingzhen remembered what his father had just said, so he asked.

"Well, it was originally the technology of the late seventies, and the fan page of that meeting was directly straight, and the heat dissipation effect was poor, and now it has been replaced with a curved surface with an inclination, and the effect is more than twice as good as the previous one, so you can also reduce the speed, and if the speed is reduced, the vortex noise at the tip of the blade will be completely gone. Although Su Guo himself studied mechanics, he had heard of fluid mechanics, and he had not learned it at all, he was just repeating the explanations of the engineers.

Su Jingzhen was even more confused, although he was also a science major, he studied financial mathematics, and he didn't know anything about it.

"It can be solved, the promised bonus can be issued to them, and we have to put forward new requirements, the noise is as low as possible, now it has been reduced to 30 decibels, then we will strive for another 5 decibels and 10 decibels, after all, the air conditioner will also be turned on when sleeping, and the smaller the noise, the smaller the impact on sleep." Su Jingzhen remembered the reward issued by Yuan Guanghua to speed up the progress before, and now that the problem is solved, it must be issued, otherwise it will be discredited.

"It's going to be a trial run for a period of time, to see what the service life is, and after the whole product is finalized, the money can be released, you don't care about these little things, you can grasp the general direction." Su Jing knows that his son is only ten years old now, and he doesn't know much about the specific production work, so he doesn't have to worry about it, Su Jingzhen's main role is that he is abroad, his thinking and vision are relatively broad, and he can do some corporate strategic work.

"I still have to understand a little bit, otherwise when I get to the workshop in the future, when others ask me how to solve this matter, I can't answer, and it will be a shame." Su Jingzhen knew his father's kindness, but he felt that he still had to go to the front line of production often, at least he had to know how his products were produced and how many processes they went through, so he had to have a general idea in his heart.

"Well, that's right, you have time to go to the workshop and walk around the workshop to see the whole process of the product from raw materials to finished products, but for now, you better get your own work done first." Su Guan smiled and pointed to the information on his son's table, a little gloating.

"Alas, Dad, or the plugs and wires and cables will be in your name, otherwise the things in my hands will be too messy and difficult to integrate." Su Jingzhen looked down at the information in his hand, and let out a wail in his mouth, asking his father's opinion.

"Don't, I'll help you get started and leave, my own plastic mold factory is about to start trial production, otherwise who will be in charge of the panel production of split air conditioners?" Su Guo was not fooled, he found that his son now had too many products in his hands, if he didn't invite a few more professional managers to take care of it, he would be so busy that he couldn't finish vomiting blood.

"Uncle Zong and Uncle Zong don't want to care, and they won't be able to find a good candidate for a while, I'm big now, if the mobile air conditioner is going to be listed, Zhang Hong will definitely not be busy." Su Jingzhen also knew that there were too many things now, and it was really impossible to find a few more people.

"You just follow the plan Joanna said before, directly ask the manager to take care of it, and a few of us will be board members, and we will check if we have nothing to do, so that it is the most effortless, and we will definitely not be busy if we want to put us directly into specific production management positions." In fact, Joanna had designed a set of management methods according to the habits of the US imperialists, but because she couldn't hire the right person for a while, this solution ended in nothing.
