"Come, I'll show you how to operate a phonograph. "Frankie also has a bit of a show-off mentality.

"Good!"

Not only Senior Barry, but even other researchers listened attentively to Frandi's explanation when they heard Frandy teach how to operate.

"This is the glass lid, and every time you record or play, you have to open it first, and then put the pointer back in place. ”

Frandy explained as he operated.

"Look, after resetting the pointer, if it's a new wax paper disc, it's already recording, you just need to press this button, but this wax paper disc has already been used just now, so you need to cancel the sound it recorded first, you need to press this clear button. ”

With that, Flandy reached for the clear button he mentioned.

"Whew!" said Barry's sudden scream, startling Flandie.

Immediately afterwards, Senior Barry directly hugged Flandi's arm that wanted to be buttoned: "Wait! My Dean, don't clear it!"

"Why?" Frankie was puzzled, isn't this a demonstration for you?

"If you clear it, your voice will be gone, right?"

"yes, and then you can record a new sound. ”

"Oh my God, please, Dean, don't clear it, I'm going to keep it, it's the first sound saved with a gramophone, and it's your voice!!" said Barry, pleading.

"It's just some sounds, if you like it, you can stay, anyway, there are quite a few wax paper discs with you. "Frandy doesn't care.

"Thank you, thank you, Lord Dean!" Senior Barry happily opened the glass lid and carefully took out the disc.

Senior Barry just thinks it's a pity that the sound recorded on this disc is cleared like this, and it was originally intended to be a private collection.

However, he has almost made the Imperial Academy of Sciences his home from now on, and he will only return to his real home once in a long time.

So the disc stayed at the Imperial Academy of Sciences, and decades later, when Senior Barry died, the oldest disc was found among his relics.

In order to find out what sound is recorded on this disc, one of the oldest gramophones was specially restored.

Because it is a disc made of wax paper, it has gone through decades, and even if it is well preserved, it will inevitably sound a little out of shape.

But some of the elders of the Academy of Sciences who were still alive still recognized it at once, and this was the voice of Flandy, the first president of the Imperial Academy of Sciences.

At that time, Flandi, the protector of humanity, had retired, and no one could find him, so this became the only audio he left for mankind.

At that time, people made an uproar, and the newly developed recording equipment was used to transcribe this sound, and then this disc became the treasure of the first sequence of the Imperial Academy of Sciences, and was permanently preserved in the most secret and secure vault of the Academy of Sciences.

Since the disc was made, it has been recorded once and shown three times, and no one has dared to attack it again.

......

The gramophone was placed at the Imperial Academy of Sciences, and handed over to the third laboratory to experiment with the medium of the disc, and Flandy did not break his promise, and told Gülen about the eating method of installing loudspeakers in the council hall that night.

Gülen was overjoyed, every time he had a court meeting, he had to speak loudly so that everyone could hear it clearly, and he should also pay attention to his own demeanor, and he couldn't deform his face because of speaking loudly, which was extremely uncomfortable.

At the end of the meeting, I always had a sore throat for a day, and I was very uncomfortable, and when I heard that the Imperial Academy of Sciences had developed a device that could amplify sound, I wanted to go to the Academy of Sciences to try the effect.

However, he was stopped by Flandie, anyway, it was a few days of work, it was better to wait for Senior Barry and Candace, and they would completely finalize the megaphone and install it in the council hall to try again.

Three days passed in a hurry, and the researchers in the Third Laboratory were like chickens, some of them were making microphones and loudspeakers, and some of them were experimenting with alternative materials for disc media.

On June 26, Monday, the day of the Great Meeting, researchers from the Imperial Academy of Sciences arrived at the Hall of Parliament with twelve large speakers and several microphones.

This is the place where the Supreme Council of the Oskaia Empire is held, except that the officials will not let anyone in and out, and if it is not for Minor, the head of the royal guard, who has been informed by Gülen, even the people of the Imperial Academy of Sciences will not be able to install it.

The microphone has also undergone some refinements, which was again the idea of Franky, and although the horn-like microphone has the effect of pitching in, it is very prone to noise and slurring.

So he simply drew a drawing of the microphone, designed it into the most common microphone shape in his previous life, and also padded a layer of cotton wool inside, so as not to spray saliva into it.

This design is really much better than the original microphone, although the sound is a little smaller, but the power of the amplifier is amplified a little more to make up for it.

In fact, the work of installing wiring in the council hall is done by craftsmen, but who among the scientific researchers does not want to go to the council hall to open their eyes?

There were not too many people who signed up for the installation, and in the end, it was Barry senior who made the decision, and more than 30 researchers from the third laboratory came to install it with various tools.

However, when they arrived at the council hall, including senior Barry, they were a little dumbfounded, because the council hall is not an ordinary palace, this council hall has a history of hundreds of years, and it took more than a hundred years to complete the council hall is 30 meters high, and the middle is a very wide hall, with nearly a thousand seats alone.

The top is painted with a magnificent mural that took a very famous painter a few years ago to paint, and it is so carefully carved everywhere that these twelve megaphones are not capable of determining the position according to the distribution of sound.

Moreover, the loudspeaker has to be installed at a high place, and it has to be installed on the line, where is it so easy to install? Just a height of more than 30 meters is difficult for these people in the third laboratory, because no one dares to climb up.

There was no way, Senior Barry could only ask Flandi for help, but although Flandi was not afraid of heights and dared to install it, like these people, he didn't know where to install it.

If it's an ordinary room, Flandre doesn't have to think about it so much, but this is the council hall, and if you install it casually, it will be too abrupt and will make people laugh.

In the end, Flandy invited Minister Dean to find experienced craftsmen in the Ministry of Works to complete the task.

Naturally, the Ministry of Works had some people who specialized in building palaces, and these buildings in the palace had been weathered for hundreds of years, and it was inevitable to repair them, and when these people were called, the installation of loudspeakers proceeded smoothly.

It has to be said that he has a specialization in the art industry, and when all the loudspeakers were installed in the evening, Flandy looked up in the council hall and was stunned to find out where the loudspeakers and wiring were installed.

In order to install a megaphone in the council hall today, Gülen deliberately moved the office of several important ministers of the empire such as Prime Minister Tang En to another palace, and now that today's discussion has ended, he brought Prime Minister Tang En and several important ministers to the council hall.

His arrival made the craftsmen who were working a little panicked, and they knelt down to pay their respects, and the scientific researchers of the Academy of Sciences were okay, because they had already seen His Majesty the Emperor during the artillery drill, so they were quite calm.

"Get up, don't worry about me, do whatever you want. "Gülen actually doesn't like these customs, but there is no way, he is His Majesty the Emperor, and no matter how much he doesn't like it, he can't help but let people kneel, after all, this is etiquette, it is a ritual that has been implemented for countless years, and it has long been deeply rooted in the hearts of the people.

"Flandy, how is the installation?" Gülen frowned as she looked at the pile of wires on the table.

"It's almost done, when the gramophone is installed, and then the wiring is cleaned up, the task will be completed. "Frandy wasn't idle, either, connecting the lines.

"The phonograph, the machine you said could leave the sound, didn't you say that the disc still needs to be experimented?" asked Glenn in surprise.

"Hehe, it only took those researchers from the Academy of Sciences two days to find a better medium, and I have tried the current discs, which are very good, very cheap, and completely practical. Flendy explained.

Since Flandy spoke in the Third Laboratory three days ago, not only the Third Laboratory, but the entire six large laboratories of the Academy of Sciences have been boiling.

Everyone in the entire Third Lab was left behind, each with a hundred gold coins, and Candace alone got a staggering one thousand gold coins, which made the eyes of the other five labs red with envy.

That's a thousand gold coins, even in the aristocratic area of the imperial capital, you can buy a house that is not too small, even if we don't research it, even if we get a hundred gold coins!

So, I don't know who heard what Flandy said when he was leaving, to find a medium that could replace wax paper to make discs, and all the labs began to help the third lab to find it.

In a short period of time, Lab 3 received thousands of materials of all kinds, and they were very lucky, only experimenting with more than 400 kinds of materials, they found the material that would give the perfect reproduction of the sound.

This material is made of resin formed by solidifying the gum of a large tree called the Tree of Magnificent Trees, and it is not a precious material from a wide range of sources.

Although the discs made from it can only be used once, and cannot be cleared and re-recorded, this small disadvantage is not a big deal because the material is cheap.
