Siheyuan: Xu Damao, I want to go to the moon

Then, a brand new speaker design that could be said to be at the world's top level emerged in Xu Damao's mind.

【Host has 3 points remaining.】

Because there are not enough samples, the existing speakers can only be optimized and analyzed to this extent. After all, Xu Damao has no way to dismantle the speakers of professional concert halls abroad for analysis. Moreover, many professional concert halls now pursue more sound field structure design, which mainly relies on acoustic engineers and architects to design and study acoustic reflection and scattering.

Therefore, due to the sample nature, Xu Damao's speaker design is limited to home theater, KTV, car audio, and outdoor small and medium-sized performance speakers. It can be used even if it is larger, but it is not professional enough and the effect of mixing heavy bass may be counterproductive.

But according to this design, whether it can be made smaller or larger is a matter for subsequent research, and it can be said that there is a lot of room for improvement. But now is China in 1958, and basically no one is researching this thing.

The whole thing is a speaker that is half a person's height, with simple left and right channels, as well as auxiliary channels such as center, surround and bass. The left and right channels of the subwoofer can be easily adjusted. Its size is twice as large as the speaker that Xu Damao used to show movies in the countryside.

In later generations, this is about 1 to 300 yuan on Taobao. The kind of outdoor pull-rod speakers used for square dancing or roadshows are not rare at all. But in this era, it is hard to say.

To put it bluntly, as long as Xu Damao fully understands this design, he can get involved in the speaker industry all over the world.

But now he has brought him to participate in the competition?

He was still thinking about whether to make a hand-pull steel frame and wheels for the speaker, just like the suitcases in later generations, so that it would be convenient to travel and move.

As soon as the idea came out, the design automatically evolved according to his idea.

In other words, the problem of appearance design can be adjusted at any time, which means that Xu Damao can release countless versions of appearance design at any time?

These 10 points are well worth it!

Xu Damao didn't think about the industry. After all, the moon was enough for him to worry about. Speakers are nothing you can eat or drink, so it's enough as long as they are sufficient.

After a while, it was time to get off work. Xu Damao rode his bicycle back to Lou's house to pick up Sha Gezi, and then returned to the courtyard.

As for the liquid nitrogen, he had already arranged with Lou Bancheng that at around 4 or 5 in the morning, the fruits and seafood would be delivered directly in the yard behind his restaurant, so as to avoid the strong smell of seafood from being transported back and forth, which would arouse suspicion. The liquid nitrogen was stored in a warehouse next to the restaurant, and Xu Damao could go and get it himself.

He planned to release some of the design drawings and experiments of the speakers every day, and also make some wrong and poorly performing prototypes to avoid being too shocking.

In this era, hitting and quarreling are just the result of youthful impetuosity, or you can say it is stubbornness. You can also talk about your family's martial arts background or that you met a Taoist master in your early years.

Even if you suddenly know medical skills, you can talk about the ancient Chinese medicine tradition of folk remedies, and say that you have a master who travels all over the world, but it is difficult to verify.

But if you are a projectionist and suddenly come up with a high-tech idea, then you really have to slice it, so you have to leave a process of trial and error. After all, your genius has to be limited.

Taking Lou Xiao'e with them, the two went to Bianyifang to eat roast duck, mainly to study the difference between this place and Quanjude roast duck - the final conclusion was that it was cheaper and tastier!

Then he went shopping in the department store and then strolled back to the courtyard.

But as soon as I entered the courtyard, I saw three and a half injured people sitting there basking in the - sunset?

Banggeng, with a broken left leg, bandaged and plastered, using crutches, living on the left;

Shazhu, with a broken right leg, bandaged and plastered, using crutches, living on the right;

Jia Dongxu, with a broken hand and broken ribs, his upper body wrapped like a mummy, sitting in the middle with his arm hanging.

Only Yan Jiecheng was standing alone, leaning against the pillar of the porch with his sleeves gathered up, looking like he was not standing properly.

The three of them slumped in their chairs, looking at the sunset with a look of despair. Next to them was Yan Jiecheng, whose face was only just beginning to swell and whose voice was lisp.

"I'm so miserable. Xu Damao broke my leg, I was demoted, fined, and even asked me to write a self-criticism?! A three thousand word self-criticism at that!" Sha Zhu said angrily.

"You're not as miserable as I am. I just reported a case, but I was beaten like this. When I'm almost recovered, I have to go to the security department for detention and fine. Who the hell did I offend?!" Jia Dongxu was also frowning. It was a complete disaster that came out of nowhere. The key point was that the security department believed that he had reported a false case, and there was no one who could testify for him. All the beatings were in vain.

"I'm even more miserable. I went to eat some steamed buns, and Xu Damao broke my leg! The school has been notified, and my classmates don't want to play with me anymore. They even say I'm a thief! After my legs heal, I'll have to be taken to the police station for detention. Dad, why don't you go for me?" Bang Geng also echoed. What's wrong with a child eating two steamed buns? Grandma said that it was taking, not stealing!

When Jia Dongxu heard his "filial piety" remarks, he rolled his eyes. When your father gets better, he will have to go to jail, so who has the time to go for you?

Yan Jiecheng, the only person standing in the room, rolled up his sleeves and said, "Can you be as miserable as me? My wife was pried open, my teeth were knocked out, I lost my job - and more,"

"Jia Dongxu, when are you going to compensate us for our bicycle? We spent a long time searching for it that night before we found it at the entrance of the security department of the steel mill. Both tires were deformed!"

"I'm telling you, my dad is very angry right now, be careful he might hold a meeting to criticize your Jia family!"

"Who cares? I didn't step on you. If you have the guts, go ask the security department for compensation!" Jia Dongxu simply refused to pay. His family was in such bad shape anyway, so let them do whatever they want!

"How about we team up to take down Xu Damao? We've never won a fight alone anyway."

"That's fine, but what's the name? We should have a more domineering name when we unite, right? And should we also bring in the old man and the deaf woman? They all have a grudge against Xu Damao! Even if they don't do anything, they can provide us with some funds so that we can eat well and recover from our injuries, right?"

"That's a great idea. I'll leave the matter of raising funds to you, Jia Dongxu. After all, you're his apprentice."

"I'm the cook. I'm responsible for cooking."

"I want to eat meat, I want to eat meat!"

"As for the name - how about - the Avengers? Abbreviated as Avengers?"

"Yan Jiecheng, forget it. It sounds just like the Women's Federation. You're just a sissy and you want revenge?"

Xu Damao looked at this scene, which was like a few old men and women chatting in the sunset. It was very funny and he couldn't help laughing.

[Avengers? Who is 55-? Who is swinging a sledgehammer? Who is running in a rage in shorts? Where is Black Widow? It can't be a deaf old lady, right? ]

"Hey, you guys still have the time to bask in the sun? And the sunset?"

"It's tasteful and artistic, and the most beautiful thing is the red sunset!"

"I admire you!"

Xu Damao, holding Lou Xiao'e's arm, pushed his bicycle into the central courtyard. There were a lot of good things hanging on the front of the bicycle. Compared with them, Xu Damao is simply a winner in life!

Only then did they realize that Xu Damao had returned. It was like the bell for the end of get out of class, and they went home cursing.

"Xu Damao, don't be so proud too soon, just wait for me!"

"It's none of my business. I was beaten by the security department. It has nothing to do with you, Xu Damao."

"Humph!"

"Can't see me, can't see me..."

The reactions of the several people varied, but in the end they did not dare to conflict with Xu Damao again. After all, they were all half-disabled now, and they had no chance of winning against the triumphant Xu Damao.

The few of them looked at each other and understood each other's idea - [Strategic retreat first, and then form alliances when things are better! ]

So, it just broke up.

Xu Damao also shook his head. They were just a bunch of idiots. However, they didn't take the initiative to cause trouble, which saved him some time. He was very upset every day.

At night, after taking care of Lou Xiao'e, Xu Damao traveled back to the moon and then went to Madagascar.

But as soon as he appeared, Li Mingmei directly wrapped him up with a large piece of cloth. Everyone knew that Xu Damao always appeared naked, so they turned away consciously.

Xu Damao looked at them and wondered, are they at sea? Are they still fishing?

Didn't you take a break from yesterday to today?

However, just after he put on the protective suit patch and put on his clothes, Xu Damao noticed that there was something being dragged behind the hull?

What the hell!

Are you really going to be pirates?!
