Become the city lord from today

Enri flicked her brown fox tail and asked curiously,"Your Majesty, how are we going to make this record?""

"We just need to trace the lines produced by sound vibrations on a piece of glass."Liu Feng explained.

This is just his guess. Although he knows the principle of making records, he still doesn't know whether the sound can be produced.

When records are first made on the earth, they must first be Various sounds are converted from sound wave vibrations into mechanical vibrations.

Just like the principle of telephones, microphones, etc., that is, a device that allows sound waves to pass through a metal sheet.

Since the volume will cause the strength of the vibration of the metal sheet, This device can convert sound waves into mechanical waves.

Then the live vibration of the metal sheet is recorded on a special template to show grooves that are equivalent to sound waves.

This principle is the principle of the phonograph invented by Edison on the other side of the earth. At that time, tin foil cylinders were used for engraving

"Your Majesty, was the environment for making this record very demanding? Enri tilted her neck and asked.

The fox-eared girl must not understand this aspect. She was thinking that if she wanted to record her voice, wouldn't there be no other noise?

"Yes, it must be in a non-noisy environment. Liu Feng nodded.

"So why choose glass?"Is glass easier to make noise?" Enri asked curiously.

"Making records out of glass is the only material we can use, but it also lasts longer."Liu Feng explained.

On the other side of the earth, people first used wax templates to record sound waves, and later switched to using a kind of shellac as recording disks.

But in the end, the recording disks made of wax and shellac were loose in texture. , there was a lot of noise, and the recorded sound was noisy and the effect was very poor.

Only then did plastic become available, and record manufacturers gradually switched to using a kind of plastic paint to make recording disks.

This kind of recording disk is also called a lacquer disk, which is dark, smooth and bright. Like a mirror, the sound recorded on a lacquer disk has no noise and the sound quality is true. This is a material commonly used by record manufacturers.

Although it is easier to make records with plastic, Liu Feng does not want to mass-produce plastic in this era.

To He knew that it would take a long time for plastic to degrade, even tens of thousands of years, and it would not be degraded at all.

He didn’t want plastic everywhere to become like the other side of the earth, so he thought of using glass instead.

"So that’s it, but what can leave lines on the glass? Enri thought seriously for a moment and continued,"The glass surface is very hard. It should be difficult to produce good texture with stone, right?" I don't think it's good to use iron either."

Fox-eared lady is smarter and understands this knowledge faster. After listening to Liu Feng's words a few times, she started to think about it in her mind. In addition, she also heard a lot about sounds before. I have some knowledge in this area, and now I think about the principles just mentioned, and I have some general ideas.

"It is difficult to leave texture on glass with stone, and the texture left with iron will definitely not be smooth. Liu

Feng pursed his lips and continued,"I think you can use diamond, so that the lines left behind will be smooth.""

Diamond is a diamond. The hardness of diamond is much higher than other stones. It is best to use it to carve the texture on the glass record.

In this way, the sound produced by the glass record on the gramophone will be particularly smooth. Got it

"Diamonds are fine, how could I forget such a good thing."Enri nodded repeatedly.

The fox-eared girl also learned a lot about diamonds. She knew that diamonds are the hardest stone in the ore.

"I'll draw the drawings later, and you can arrange for someone to do it. Liu Feng ordered.

He had to draw a lot of drawings today, including those for records, gramophones, and how to turn sounds into textures.

This is a long process, not only the structure but also the What is the easiest way to do it?

"Yes, if there is a gramophone, we will be able to hear music in the streets and alleys in the future."Enri happily shook her fox tail.

"In this way, we don’t have to go out of our way to listen to them singing. We can listen to music while processing files."Mina is also looking forward to it

"Yes, music is still very important."Liu Feng agreed.

This was something he realized some time ago. He originally liked listening to music on the other side of the earth.

Sometimes he would find time to go to concerts and the like, but after traveling back, because of various Due to these conditions, he has not listened to music for a long time.

And he has been here for a very long time. Even when he traveled back to the earth, he did not think about listening to music. The real reason that made him want to make a gramophone was Annie Waiting for the appearance of others, I have returned to Earth to see the gramophone.

It can be said that the time, place and people are favorable. Since the conditions are met, it is not bad to give it a try. It is naturally good to succeed. If not, spend more Spend some time researching, and you can still get good results in the end.

"Your Majesty, if the gramophone is produced by then, will we sell it?"Anli immediately thought from the perspective of a businessman.

Whenever she sees something new created by His Majesty, all she thinks about is whether it can bring huge wealth to the Han Dynasty.

Maybe it is the things she has been dealing with every day. It must be related to the finances of the Han Dynasty, so I subconsciously think of this aspect.

"No, things are rare and valuable. It would be nice to only have this in our tallest building and in Chang'an City. Let others be jealous for a while."Liu Feng shook his head.

Things that only the castle had before, now everyone can have, and the sense of distinction between up and down began to slowly disappear.

This is also the reason why those civilians are becoming more and more arrogant. Thinking that they themselves had it anyway, the sense of awe in their hearts began to slowly disappear. The last thing Liu Feng wanted to see was this. If he wanted to manage the Han Dynasty well, he must let the common people There is a sense of awe.

Of course, they are not saying that they don’t have it at all, but they just say that the things that can create a sense of class have suddenly disappeared, and they feel that they are no longer shackles, and slowly began to change in their hearts.

"I understand His Majesty's intention. This thing will definitely make them feel itchy when the time comes."Enri covered her mouth and smiled.

"This is the effect you want."The corners of Liu Feng's mouth rose slightly.

He began to look forward to the production of the gramophone, and even more hoped that it could be successfully produced in one go.
