Chinese entertainment for engineering students

The courtyard is very lively today because all Wang Xu’s roommates have come. Today is Sunday, a rare day off. Wang Xu originally approached Zhou Feng and asked him to work on the speakers together. Later, during the night talk, he said that everyone was planning to get involved, so they would come. Even Uncle Qiang from next door came over.

Ever since he started working on the "supercomputing" project, Uncle Qiang has been coming to Wang Xu's dormitory often. He has almost become a dormitory member, kind of like a non-staff roommate.

Today was no exception. Hearing that Wang Xu was fussing again, he also ran over.

Today, the carpenter Hu Yang reported for duty for the first time. He was first assigned to find Wang Jinghua and was assigned to the logistics department. People who didn't know where to put them were usually placed in this department anyway.

Wang Xu told Sister Hua about this matter after a phone call yesterday. Arranging someone was not a big deal, but Wang Jinghua was obviously very satisfied. Wang Xu finally remembered that there was still a listening room that he hadn't bothered with.

That set of Shanshui speakers would be more expensive to rent than to buy. Well, Wang Xu admitted that he had been neglected. But there's nothing I can do about it. I've been too busy lately, with so many projects and so many people, so hobbies like the listening room have been sidelined.

In the final analysis, there is a difference in mentality between Wang Xu and Wang Jinghua. Wang Xu started this studio more because he thought it was fun. Although he tried to fool people in a set way, Wang Xu himself knew that he actually did not invest too much. s concern.

At the beginning, I just wanted a good recording studio to record my and Wang Fei's songs. Later, after I came up with a name, I came up with the idea of ​​​​looking at the whole country and even overseas.

My own interest is more in creating, whether it is copied or not, it is still something that does not exist in the world. If I bring it myself, the sense of accomplishment even exceeds the pleasure of making money from it.

Recently, he doesn't always have enough time, and Wang Xu has already planned to quit the last two games in the evening to catch up. Because of the reputation, the first game alone can generate almost 50 emotion points, and I am not in a hurry to change skills, so I should stop a few first.

This way you can free up some time to do things you like, such as those few paintings that you haven't started yet since inspiration struck last time.

As for the daytime, aren’t there more interesting things, such as the power amplifiers and speakers I’m currently working on?

Audio equipment, to put it simply, is a bunch of things that play back the stored audio so that people can hear it. From small speakers that cost a few yuan, large speakers that are common in rural areas with tens of yuan, all-in-one speakers that cost hundreds of yuan for street playback, luxury modular speakers that cost thousands of yuan for homes, all the way to villa equipment that costs millions. Stage equipment worth tens of millions, and stadium equipment worth hundreds of millions.

It can cover almost any price range you can think of. Anyway, just a simple thing like playing music can really make you feverish to death.

Well, if you insist on saying that there are billions of Soviet black technologies that can blow rabbits to pieces, then you are just making excuses.

The technology Wang Xu bought was speakers, but when the goods arrived, Wang Xu saw a bunch of speaker combinations. There are many large and small ones, both active and passive. They look like a series of products of the same brand.

All products come with detailed technical documentation, which is less like a manual and more like a paper. It theoretically demonstrates the sound characteristics of these speakers. These documents look very interesting and make Wang Xu gain a lot of knowledge. He even I feel that these documents are much more valuable than the speaker drawings.

Of course, there are piles of various raw materials and production methods of devices. Some of them are even duplicates of the microphones I bought before, such as the black fiber cloth covering the outside.

Wang Xu plans to slowly make these things and try them out. Of course, the first thing is the speaker itself. This time, he will use replacement parts to check the quality of the speaker first.

Things like speakers are too subjective. If you want to talk about microphones, you can also say that they are the best in the world. After all, there are hard indicators. But when it comes to speakers, that's nonsense. Everyone claims to be number one, but no one can really convince others.

Now that Populus euphratica is here, let him make the box first. This thing is not troublesome to make, but it takes time. Just the various drying times add up to more than a week.

Hu Yang was indeed an old carpenter. Wang Xu drew a sketch and checked a few dimensions. After a little explanation, he understood what he wanted to do. Without any nonsense, I took the initiative to go to the warehouse to cut materials and work. There was originally a small carpentry room next to the warehouse, which was arranged during the renovation.

Since he arrived, he has not asked any other questions except where the tools are, where the materials are, and where the workshop is.

It's really strange that this person, isn't he talking about a rock youth, has a dull sense of déjà vu. The contrast is too strong. Now that you say he is a professional carpenter, Wang Xu will not find it strange at all.

Forget it, never mind, Wang Xu is not good at psychological counseling. He looked at his brother’s actions from a distance, and he was very professional. There shouldn’t be any problems with making such a box, so let’s ask Lao Yu later. You should know something about the situation.

The brothers from the dormitory were looking at a circuit diagram that Wang Xu gave them. This diagram was not bought, but designed by Wang Xu himself. Of course, its core basis still comes from the system.

It was a set of circuits related to the internal decoding and amplification of active speakers, but interestingly, the decoding part was very simple, and there was no big difference between the past products in Wang Xu’s memory.

However, many interesting innovations have been made in the power amplification part. If nothing else, these circuits should be able to reduce some clutter during the amplification process. In layman's terms, they ensure that the amplified signal is more consistent with the original one. .

Wang Xu planned to take this part out separately and put it into effect to see the effect.

Mizuki's brothers are not really needed for the speakers, and they can't help, but we can let them work here. I have already done a signal reception, so it shouldn't be a problem to do a power amplification.

Taking the drawings and explaining them in detail from beginning to end with several brothers, the result was beyond Wang Xu's expectation.

Several brothers have just started taking professional circuit courses at this time. Although adhering to the tradition of being a top student, I have already finished reading the book early. But looking at such a complicated circuit diagram, I am still a little confused.

Wang Xu didn't know what to do. There were times when the top student didn't learn how to do it, and he felt a little impatient. However, we didn't dare to pull out seedlings in other places to encourage growth. In the land of Shuimu, we really weren't afraid of this. Give them a good measure. Pulling out should be a problem. Not big.

So, Wang Xu avoided his roommates and quietly called Teacher Yan. After explaining the cause and effect of this incident, Teacher Yan said, "It's a good thing. The circuit was paid attention to last time. It's not too much to expect this time."

So I immediately promised, no problem, you ask a few of them to come to me, and I will arrange a teacher for them to take care of them. Isn't it just a surprise to improve their progress? It seems like no one has done the Olympiad yet.
