Great Tang princess

Chapter 690 Phonograph Experiment

Li Yuechen thought about dividing the existing craftsmen into levels according to their level, and then awarding them with different certificates.

With the gradual improvement of the system in the future, their treatment and so on will also change according to the level.

From level one to level eight, there are four stages in total.

They are first and second level (apprentice), third and fourth level (technician), fifth and sixth level (artisan), and seventh and eighth level (craftsman).

And with the gradual improvement of the education system, illiterate craftsmen like Wang Gangdan will become famous in the future.

In the future, craftsmen must be able to draw and calculate various data of the product, and at the same time, they must be skilled enough.

Pei Bishu affirmed this idea.

Although it seems a little troublesome, it has become more fair for all craftsmen.

Craftsmen rely on their craftsmanship for a living, and it is actually quite fair to determine their remuneration according to the level of their craftsmanship.

The whole negotiation process was very fast and the atmosphere was quite harmonious.

So Li Yuechen asked him to discuss with Wang Gangdan and the others during this time to finalize the system.

But soon, the apprentice's voice came out from the copper speaker: "The heaven and earth are dark and yellow, the universe is prehistoric..."

Entering the laboratory, I saw the phonograph already placed on the table.

However, when he walked in, he found that it was not the case at all.

The craftsman replied: "Return to Your Highness, according to our adjustment, it can rotate 1 times in one minute."

The first is to buy a piece of land in Dongdu, Chang'an and Fanyang, and then build a bank.

Li Yuechen was not in a hurry, after all, Wang Gangdan had already said it, and it would take at least three months to complete the engraving.

Li Yuechen didn't personally intervene in this matter, so he sent someone to choose the land.

The decoration style of the Princess Mansion is very simple and elegant, which is clear at a glance and at the same time gives people an extraordinary feeling.

Although it is not big, there is indeed a slight noise during playback.

"How long does it take in one minute?" Li Yuechen asked.

They have all seen the influence of the football game, and as a big family, they are much more informed than ordinary people.

But in mid-October, news came from the Academy of Engineering that the prototype of the gramophone was ready, and the princess was asked to go and have a look.

So you can choose the name of Qinglong if you want, besides, it's just Qinglong, not a five-clawed golden dragon, so there's no need to be so sensitive.

I can even hear it myself, and I believe those who understand music can even hear it.

Li Yuechen smiled: "So, if you want to play, you must first become the number one in the country."

This guy didn't recite the thousand-character text very fast. Li Yuechen estimated in his heart that it took more than six minutes and less than seven minutes.

But if it is recited, it still takes some time.

So the emperor doesn't have to be a god, the emperor is the emperor, he can be called the son of heaven, but he doesn't have to be a real dragon.

This thing is not difficult, and the craftsmen can easily make it.

"My aunt once said, you can't be afraid of failure. If you don't play because you are afraid of losing, wouldn't it bring down my royal family's prestige even more?" asked the young Li Longfan.

Only Li Yuechen shook his head slightly. To be honest, the sound quality is still a bit poor.

They all nodded and agreed, and decided to form their own football team.

Anyway, the bank will ship a large amount of currency to the warehouse every night, and it will not stay in the bank.

While he was reciting aloud, the sound also caused the stylus below to vibrate through the copper horn, and carved grooves on the rotating wax sheet that could not be discerned by the naked eye.

Li Yuechen immediately got up and came to the Engineering Academy to check their works.

The craftsman next to him took over the conversation: "I followed His Highness's instructions and made this clockwork. Just insert this thing into the hole of the clockwork, turn it and release it, and it will drive the disc to rotate..."

The voice was actually preserved!
The craftsmen present knew very well that this was another invention that could change the whole country!

In other words, it is very likely that this will develop into a large-scale international event in the future.

After being stunned for a few seconds, all the craftsmen cheered in unison, and some even couldn't help but jumped up on the spot!

It doesn't need to be too precise, as long as there is an approximate number, at least it will be enough to know how many banknotes will be printed.

Li Yuechen also knew the curiosity in their hearts, so he didn't pretend to be a secret, and immediately inserted the key again to wind up.

Of course, this money will definitely not be spent in vain, and the tickets for the game can be divided into them.

Seeing Li Yuechen raised the stylus, the surrounding craftsmen gathered around one after another, intending to get closer to see if the apprentice's voice was really recorded.

I observed the remaining place on the wax sheet and found that there was still about one-fifth of it.

Li Yuechen also told them that they can come to consult at any time if there is something they don't understand.

Moreover, they can also get sponsors by themselves, plus the future player transfer fees after the system matures, etc., they can only earn a lot more.

Considering that there are not too many bank customers today, there are not many employees, and five people in each bank are enough.

After tightening the mainspring again, Li Yuechen first replaced the stylus with a new one and removed the counterweight on it.

After all, although they had never heard of the method of making money that the princess mentioned, the merchants had a keen sense of smell, and they all felt that it was profitable.

For example, there is a strange-looking ornament on the table. It is obviously two sticks nailed together, one long and one short, but it can keep turning, fast and slow.

Li Yuechen sat on the podium and said to them: "It's not so easy to play. You are all children of the royal family. If you play, if you can't perform well, wouldn't you be ashamed?"

There is no sound amplifier in this era. In fact, even if you recite aloud in front of this speaker, the final restored sound may be smaller.

After all, I was still a child, so I really didn't think about this issue for a while.

After entering the gate, seeing the simple and elegant courtyard in the mansion, they all had a new impression of the princess.

……

After the partnership was finalized, the businessmen didn't wait too long, they got up and resigned one after another, and went back to work on the formation of the football team.

Then, she gently placed the stylus on the spinning wax.

After finishing the football team, Li Yuechen continued to work on the bank while attending class.

"Well, let's try it today." Li Yuechen nodded with a smile.

Li Yuechen waved his hand to the apprentice next to him: "Have you ever learned the thousand-character prose?"

After finding it, go to the engineering institute to draw out the design drawing and build it with cement.

"Return to Your Highness, I have learned." The apprentice replied respectfully.

Seeing this scene, Li Yuechen smiled in relief, the children really became a little different from this era.

The owner hides in a row house, and most of the houses move in and out regularly...

In this era, tempered glass cannot be made, so the counter should use that kind of iron fence.

After entering the main hall, you can also find that there are many things that you don't understand.

……

When the apprentice saw it, he quickly read aloud to the loudspeaker: "The heaven and the earth are mysterious and yellow, the universe is prehistoric..."

Li Yuechen nodded to show that he understood, then took the key from the craftsman and started to wind it.

The moment he finished reciting the last sentence, she also raised the needle.

In fact, in the eyes of the ancients, the residence itself reveals the personality of the owner, or in other words, certain characteristics.

"Okay, start recording here, and recite it aloud to Ben Gong!" Li Yuechen waved, then picked up the singing and said to him, "Are you ready?"

Mainly with the development of science and technology in the future, the concept of time must become more and more clear, so Li Yuechen put forward this concept in a timely manner.

Because it hasn't been painted yet, the shell below is the log color.

They all know that envoys from various countries have written letters to go back to form a football team.

These things are all decorations that Li Yuechen made when he was giving lectures to Princess Xuancheng.

Although I have always had confidence in the princess's invention, when I heard that the sound was really preserved, everyone present couldn't help but take a deep breath and feel my scalp go numb!

Pei Bishu came to her and gave her a detailed introduction: "Your Highness, I have tried using wax, ceramics, rosin and other things... just waiting for His Highness to come and experiment."

In mid-September, many collateral descendants of aristocratic families in charge of business came to the Princess Mansion one after another.

As for security, some retired soldiers can work as security guards.

After all, things like saving voices were really unheard of before.

So Li Yuechen put the needle on the rotating wax plate in front of him.

"This name is quite bold..." Li Yuechen smiled, "Okay, I can take it!"

"It's true." Li Yuechen smiled, "But since there are people in the country who are more powerful than you, why do you still want to go up?"

Then the key was withdrawn, and the wax was spun.

One of them asked: "Your Highness, is there any restriction on naming this club...?"

Because the blank sound was recorded for a few seconds at the beginning, there was no response as soon as the stylus was touched.

At the same time, a group of people were selected from the original group of students to arrange the work of bank staff.

"As a soldier, how can we put all our energy on such fun?" Li Longye on the side shook his head.

The owner hesitated Feng Tang, most of the house is full of twists and turns;

In the eyes of the ancients, this kind of shock is even stronger than flying into the sky.

Li Longfan nodded: "The nephew worked hard and became the number one in the country."

Even Wang Gangdan and the craftsmen who have been busy making surprise engravings surrounded them curiously.

After explaining the matter, he continued to go back to teach the children.

Therefore, the main security threat to the bank is during the daytime. As long as retired soldiers are used as security guards and armor and weapons are issued to them, it is enough to deal with general emergencies.

Because of the wonderful performance of senior Li Longji on the field, a group of children asked her when the next game will be held, and they also wanted to play.

The escort of the money is still in charge of the active Jinwu Guards.

"Well, you are welcome. Sit down and talk!"

Li Yuechen picked up the teacup: "Tell me first what name you plan to take?"

To put it bluntly, let them each spend money to form their own football clubs.

At the same time, Li Yuechen asked Princess Xuancheng to calculate how much currency is currently circulating in the Dongdu and Chang'an markets.

In fact, she agreed for a reason. In the future, she does not want to make the royal family into a religion-like nature.

……

While the apprentice was reciting, Li Yuechen was also listening.

"This……"

In other words, the trial run of banknotes will be the first month of next year at the earliest, so there is no need to worry about this kind of thing.

While the apprentice was reciting, Li Yuechen had been paying attention to the movement of the stylus on the wax plate, and at the same time observed the tightness of the spring inside through the glass.

……

Li Yuechen asked Xiaodong to pour tea for them, and then chatted about forming a football club.

The apprentice didn't expect to ask him to record, but he nodded immediately, indicating that he was ready.

The thousand-character text itself is not too long, only a thousand characters.

And the big speaker above is also an unpolished copper speaker, which looks like an antique that has been placed for many years.

The concept of minutes was also told to them when drawing the design drawings.

Although she couldn't understand many of the principles, it was interesting to put this thing, so she put it like this.

A group of people hurriedly got up and saluted again: "I have seen Her Royal Highness."

Not to mention that the princess's reputation is there. Doing business with her has a very high chance of making money.

After they were all seated, Li Yuechen, who was dressed in a bright red round collar robe, walked in.

"Blue Dragon!"

After tightening, pull out the key, and the wax plate on the turntable has kept turning at a constant speed.

The other people around were all quietly holding their breath and concentrating, not daring to make a sound, for fear of disrupting the rhythm and affecting the results of the experiment.

In other words, the master is majestic, and most of the house is full of wind and horse walls;

Sure enough, after the group of people looked at each other, they already had an answer in their hearts.

Since it wasn't too urgent a job, there was no reminder. In October, it was less than half of the calculation.

So naturally dare to agree immediately.

In class recently, the most discussed football match was held some time ago.

In fact, according to Li Yuechen's understanding of this thing, even if they made a sound, it should be difficult to record it.

Then Li Yuechen waved his hand: "No problem."

Calculated in this way, a wax sheet can record a little more than 8 minutes of sound.

Another person next to him immediately said: "Your Highness, this...isn't appropriate?"

There is another ornament on the table on the other side, that is, four balls are hung on a horizontal bar. The iron balls on both sides keep jumping up and down and hitting the middle iron ball, sending out continuous Crisp.

Now that the templates for banknotes have been made, the establishment of banks is naturally on the agenda.

And Princess Taiping likes to do business. In the eyes of many business people, this princess is rich, creative, and favored since childhood. Most of the houses are decorated in an extremely luxurious style.

I believe they can see the potential in it.

After all, this is to discuss business with the princess, and no one dares to slap the table and blush.

Fortunately, it's not a big problem, at least it didn't have much impact on the recording itself.

Neither the intonation nor the timbre have been changed, at least it is indeed a mature phonograph.

Next, further experiments can be considered.

　Thank you [What name do you choose] for rewarding 100 starting coins!
　　There is only one update today, and I have been dealing with my father's funeral at home for the past few days... I have to run around every day.
