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

"I'm Xu Damao, the projectionist at the steel mill's publicity department, and I'm also the winner of this show's first place. You said there's something wrong with the speakers, which means there's something wrong with my first place. Are you doubting everyone's judgment? It's related to me, so of course I have to stand up."

"What I'm talking about now is the source of the speakers. This has nothing to do with you, right? Could it be that you got this speaker?" Ling Feng frowned. You don't understand what I'm saying, right?

Since you want to die, I will grant your wish!

The senior leader of the Ministry of Metallurgy did not come forward to mediate at this time. If it involved treason or smuggling, it would be a serious political problem. No matter what the reason, he should not interrupt or cover up for either party at this time.

Director Yang was even more frightened at this time. How did it involve treason and smuggling?

Who am I, where am I, and what am I doing?

He didn't dare to say a word now.

Xu Damao smiled and continued, "Of course it has something to do with me? I planned and arranged both programs, and I taught Director Li."

"Even that speaker was designed and made by me. I'm the source of all your problems, so of course I have to come forward to explain, right?"

When the first sentence was heard, the whole audience was excited. Isn't Xu Damao really too bold to brag?

You plan and direct? How can a projectionist like you come up with such a fancy and high-end show?

With this ability, why do you want to be a projectionist?

The people in the courtyard sneered even more. Don’t we know what level you, Xu Damao, are?

You are the one who planned and arranged it, and you are the one who taught me, Director Li? Why don't you go to heaven?

You have to consider the occasion when bragging, right?

This guy is crazy, definitely crazy!

When the second sentence was heard, the whole audience fell silent.

"What did he say?"

"He said that the speakers, which are world-class, were designed and made by him."

"Isn't he a projectionist? Why is he working as a speaker?"

"So it's just bragging?"

"Hahahahahaha!"

The whole audience laughed, even Ling Feng, including the leaders of various factories and the leaders of the Ministry of Metallurgy, were amused by Xu Damao's remarks.

"Impossible, absolutely impossible!"

“The best speaker technology is in England, Germany and Great Britain, that’s a fact!”

"We in China don't have this technology. Even the Bear Country doesn't have it, let alone a projectionist like you!"

The big boss was there watching them argue. He didn't mind Ling Feng making things difficult for Li Huaide and Xu Damao, because since there was suspicion, then it had to be investigated thoroughly. Whether both sides suffered losses or Ling Feng won or lost, it didn't matter. What mattered was the truth and the result.

Xu Damao shook his head and said, "You say it's impossible before you even try it. You're a typical example of someone who only thinks the moon is rounder in foreign countries."

"But have you ever thought about this: we are all human beings. Why can they do it, but we can't?"

Xu Damao's words were more serious, he almost said that this guy was worshipping foreigners, but Xu Damao said it on purpose. If you want to mess with me, I can only kill you.

I am a very fair person!

Ling Feng also sensed the murderous intent in Xu Damao's words. He wanted to nail him to the pillar of shame for worshipping foreigners and fawning on foreigners!

"It's useless to say these. If you don't have evidence today to prove that you designed and made it, then we'll have to call the police to investigate!" Ling Feng shook his head. He didn't want to argue with Xu Damao and was ready to handle the matter directly.

Xu Damao shrugged his shoulders: "Come on, tell him who designed and made this thing."

The two teams at the steel mill said in unison: "Xu Damao!"

Ling Feng replied calmly: "They are all your colleagues. Their testimonies are not credible. I also suspect that they are also involved in your smuggling or contact with foreign forces."

"I want evidence. Testimony alone is useless. You are a projectionist and your design and production technology is better than that of England, Germany and Da Meili. Who would believe it?"

This is to catch all the people in the steel mill in one fell swoop!

Its heart is awkward!

Xiaoxia didn't know what to do on the scene. It was just a party, how could it get to the point of life and death? And no one dared to intervene, nor did they dare to let it go and pretend nothing had happened.

Xu Damao was helpless. If you are willing to die, I am willing to bury you. Don’t run away after school!

So he winked at the backstage: "Bring all the things up here."

Then, a worker dragged up a small trailer used to transport steel ingots within the factory, and on it were various types of speakers.

"This……"

Ling Feng was stunned. What did this mean? Why were there so many?

It seems that there are some semi-finished products, which are made very roughly and have not been painted.

"Half a month ago, we found that the sound quality of the speakers in the auditorium was not good, so I thought of making one myself."

"In our Huaguo Middle School physics textbook, it is said that electromagnets and permanent magnets can repel each other. Then the electromagnet is bound to the paper tube, and it can generate reciprocating motion by switching between electricity and non-electricity."

"The reciprocating motion, coupled with the paper plate, can generate vibrations, and thus sound. It is a very simple electromagnetic physics phenomenon."

The big boss and all the factory managers of the subordinate factories looked at each other in bewilderment. What was Xu Damao talking about? Was it the Book of Heaven?

How do electromagnetism, permanent magnets, reciprocating motion and so on eventually turn into sound?

Maxim nodded: "Yes, your textbook is based on the teaching syllabus of our country, and there is indeed such a record in the chapter on electromagnetism."

There was something he didn't say - the principle is simple, but how did you make such a professional speaker?

This is not from 1 to 2, Xu Damao is going directly from 1 to 100!

No matter how talented you are, it's impossible to make such professional equipment in just half a month, right?

This is unscientific!

But Xu Damao took out a very ugly wooden box from the pile of speakers: "This is my first experimental product, a paper cone speaker, and it still works."

"And this is the second test subject. The current was too large and it burned..."

"The third one has a good bass effect, but the power is not enough and the surround sound effect is not there..."

"The fourth one, the tweeter effect is average, it is completely covered by the bass effect, give up..."

"The fifth one has a decent effect, but it has no knobs, so it can't be adjusted, and it can't produce a virtual main sound position..."

"sixth……"

"..."

“And these two speakers are the result of my 15th experiment. They are pretty good, so I brought them up for today’s performance.”

At this time, Xu Damao took out another large stack of design drawings. From a distance, various data were recorded on them. A rough estimate was that there were at least forty or fifty of them.

"These are the design drawings of all the speakers, as well as various test data. I drew them every day in my spare time over the past half month."

"And it was drawn in front of two performance teams from our steel mill. They can all testify to this."

Everyone was stunned. How come Xu Damao looked more professional than those engineers?

Is this true?

They couldn't make any judgement and could only look at each other, not daring to speak.

"I know you still doubt whether we will collude with each other, but what I want to say is-"

"This thing is really simple. More than half of the people in our two teams can make their own paper cone speakers."

He pointed at the team members behind him, and immediately half of them raised their hands.

"I can!"

"I can do it too!"

"It's really simple, but the effect is a little poor."

"Yeah, it only took me a few minutes to learn how to do it. I made one for my son and it works even when it's connected to a radio!"

Xu Damao looked at the leaders on the judging panel again and said innocently, "This isn't high-tech at all. Why are you so nervous?"

"Do you need us to do a live demonstration? We're ready to go."

"It's really not difficult if you have hands to do it."

Ling Feng looked at the group of steel mill workers who were laughing and holding up their hands. So many people knew how to do it, so they definitely couldn't be lying!

And there are so many experimental products, design drawings, and various experimental data on site - that is to say, there is a complete design idea and trial and error process, which cannot be faked.

They dared to perform one for you right there?!

Ling Feng was depressed.

If you made it yourselves, then you should have said so earlier!

Tell me earlier!
