"Brother, come and see if the shape of this speaker is exactly the same as yours?"

Yingheng was very excited when the audio was made.

Ying Feiyu had just said a few words to Huang Yuan, but he was pulled to the speaker, hoping to get his encouragement!

"Um……!"

Ying Feiyu looked at it carefully and nodded repeatedly, "It's true, it's exactly the same!"

"Look at this microphone!"

Then he excitedly handed the microphone to check it.

"It's not bad!"

Although the microphone is a little bigger, it seems that there is no problem overall.

"There is no way, the microphone is really no way to be more refined. This has reached its limit. Maybe it can be modified in the future!"

Ying Heng also knew that there was some difference in size and said with a little regret.

"As long as the effect is good, the gap in the microphone can be completely negligible! With the development of technology in the future, we will definitely be able to create better ones!"

Ying Feiyu encouraged.

With current technological conditions, it is not easy to study audio, and it is impossible to have such high requirements in terms of size.

Moreover, the difference between the two is not much, it is just the length of a little finger!

"Don't worry, brother, we have tested it, and the effect is definitely no worse than that of the commercial city!"

Speaking of this, Ying Heng ordered people to turn on the electricity with confidence.

When he used it for the first time, he was still busy and didn't know how to adjust it.

It’s different now. He participated in the research and manufacture of the machine throughout the process. Even every part inside is very familiar, let alone how to use it!

After connecting the circuit, I plugged in the microphone and blew twice in front of me. The huge roar instantly rang throughout the workshop.

The onlookers quickly covered their ears and showed a surprise expression!

"Brother, is this effect OK?"

In order to show the effect of the speaker, Ying Heng put the volume to the maximum, and said this with a proud look on his face.

Huge sound waves were emitted, and everyone felt the ground under their feet tremble slightly, and the glass in the workshop was also buzzing.

And their heartbeat suddenly accelerated, as if they were about to jump out of their throats!

"Okay, okay, brother, you really don't have to turn the volume so high!"

Ying Feiyu covered his ears with one hand and asked him to stop with the other hand, for fear that he would say a few more words later.

His young heart can't bear it!

How could he see the audio?

This is to kill him!

"Haha! I'm just trying to prove the effect of the speaker!"

After seeing the reactions of everyone, Ying Heng felt that he had done something a little too much and laughed awkwardly.

"Brother, if you want to prove the effect of the speaker, you don't have to turn the volume to the maximum. As long as you put it in half, we can naturally guess the maximum volume!"

Ying Feiyu shook his head and smiled bitterly, very helpless.

It can be seen how anxious this kid is to prove himself!

"Uh... what the emperor said makes sense. Why didn't I expect it? Haha!"

Ying Heng scratched his head awkwardly and turned the volume of the speaker back halfway.

He aimed at the microphone and continued, "Brother, how is the volume?"

Even so, everyone in the workshop felt deafening and did not dare to take down the hand covering his ears.

"Very good! Half the volume is enough to use!"

Ying Feiyu nodded repeatedly.

"Brother, is this considered successful in development?"

Ying Heng stared at him with anticipation.

"For sure! Of course!"

"Hahaha! That's great!"

Ying Heng almost jumped up happily.

Like the electric motor, this was done by him with craftsmen.

"Congratulations to young master! If you have any electrical manufacturing items in the future, young master can take people to complete them independently!"

Huang Yuan bowed his hand and said with a smile.

"Haha, Huang Yuan, are you looking for help?"

Ying Feiyu saw through his little thoughts at first sight and said immediately.

"Hehe! Nothing can escape the eyes of His Majesty...!"

Huang Yuan was really honest and didn't make any excuses and admitted it directly, "I said it myself before! Let me push out some of the things in my hand, so that I won't let my hair bald! Now Gongziheng is interested in scientific research and creation and is very talented. In just a few years, he led the craftsmen to create audio. How can this talent be disappointed?"

"What you said is nice!"

Ying Feiyu gave him a blank look with a smile.

But Ying Heng was extremely excited.

With this success, there will be more things he can bring people to study in the future!

"Hahaha! I just want to live a few more years and contribute more to the court!"

Huang Yuan smiled.

"Don't worry, even if you push all the electrical appliances out, you won't be idle!"

The industry of Daqin has just started, and there are still many things to be manufactured.

But Huang Yuan mistakenly thought that he was talking about managing those factories, "What His Majesty said is that those factories alone are enough to work!"

"I have said a long time ago that some irrelevant factories should be handed over as soon as possible and find a few trustworthy people to manage! However, the arsenal must not be handed over to others easily, and must be strictly controlled at any time!"

Although there has been no war in recent years, the production of guns and ammunition in the arsenal and the development of new weapons have never stopped.

The same is true in the future, and the storage of ammunition cannot be stopped at any time.

If you wait until the war happens before thinking about giving birth, it will be too late!

The arsenal is the core of the Qin Dynasty and an important weapon to help the Qin Dynasty rise. It cannot be stopped, let alone leak it out!

"Your Majesty, don't worry, please remember! Those sports equipment, cameras, bicycle factories, etc. are handed over to the officials' nephews to manage! The officials are really worried about the shipyard, automobile factories, train factories and other large machinery factories, so they always take care of them themselves!"

Huang Yuan surrendered and reported.

"In addition to managing factories, there will definitely be many machinery that you need to take people to manufacture and develop in the future. It is better to put the factory out as soon as possible! Otherwise, you really can't take care of it! Don't delay the research and development of machinery at that time, and there will be omissions in the factory!"

Ying Feiyu reminded.

"Your Majesty, don't worry..."

Huang Yuan made a sure guarantee, and then his eyes lit up and he asked curiously, "His Majesty has developed a new machine recently? Can the drawings be drawn?"

"Not yet! I just had some ideas!"

Ying Feiyu shook his head.

There are still many things to be made, and he hasn't figured out what to make first!

"Brother, can the audio be made in large quantities?"

Yingheng definitely hopes to build a factory and manufacture a large amount of results after finally researching them.

So he looked at Ying Feiyu with anticipation!

Ying Feiyu pondered for a moment and said bluntly, "Speaker is indeed of great use in some aspects, but the area and frequency of use are not very wide!"

"What the emperor brother means..."

Hearing this, Ying Heng's hopeful eyes suddenly became lonely.

"Don't worry, brother, the audio has been successfully manufactured, and production must be produced, but the production volume will not be too large, as long as the demand is met!"

Ying Feiyu explained with a smile.

"well!"

I heard that it would start to create, and light appeared in Ying Heng's eyes.
Chapter completed!
