The last time I came was three days ago, and many of the newcomers had already met Frandi, so when Frandi reappeared this time, it didn't attract onlookers like last time.

But almost all the researchers who met Frandi stopped along the way, some greeted, some looked at him, and some saluted.

Flandy also said hello all the way forward, and it didn't take much effort to get to Laboratory Three.

The entire Third Lab knew that Flandy would be coming today, and they had already lined up to welcome him, and as soon as Flandi entered the door of the lab, he heard a welcome sound.

"Hello, Lord Dean!"

"The Dean is here again. ”

“......”

Flandi felt that the scene in front of him was somewhat familiar, wasn't this the formation of the people in the previous life welcoming the leader's inspection.

"Okay, okay" Frankie waved his hand and said, "Don't be so polite, it seems that I have come here relatively rarely, everyone doesn't need to be so welcome, let's do something, I'll come a few more times in the future." ”

For this kind of formation, Frandi can't say whether he likes it or not, and he doesn't dislike it once in a while, but if he has too many times, it's very annoying.

After all, the Imperial Academy of Sciences was created by himself, so it can be said that this place is his own people, and Flandi doesn't want to be too harsh on his subordinates.

"Flandie, we've been working together for three days, and now it's time to wait for you to accept it, so you might as well let them watch it too. ”

"I see, well, what about Candace?"

"I'm here!" Candace squeezed through the back of the crowd. She was small, and when Frandy came just now, everyone else rushed forward, and she couldn't squeeze anyone else even if she was a girl, so she was not in a hurry, just watching from behind.

"How's it going? I heard Senior Barry say that you've worked on this megaphone, and it's working very well?"

"Lord Dean, so many people help me, of course I have studied it, you can try it, you will know how it works. Candace didn't greet Frandy politely, and beckoned to him.

"Okay!" said Frand, and the twenty-odd people cheered out of the way.

I came to the workbench where Cannes last time, and saw that a total of three loudspeakers were made: large, medium and small.

Each speaker is exquisitely made, and the enclosure is carved with some patterns, not even inferior to those of previous generations. Much stronger than the case of the gramophone that Franky had Tom and Jerry bring to the table.

"Here, Dean, just talk to it, I'm going to take the smallest speaker now. ”

Candace handed Frandy a small, equally delicate microphone, which was different from the microphone that Franky was familiar with in his previous life, and was also like a horn, just speaking through the horn to collect the sound.

"Okay!" Franky pointed the speaker of the microphone to his mouth, cleared his voice, and said softly, "Hey, can you hear me?"

At the same time, Frandi's voice came out of the trumpet's speaker, almost unmatched, and anyone could tell that it was Frandi's voice when they heard it.

"Ah, that sounds like oh!" Katrina snorted softly.

The people of Lab 3 must have tested it many times and were familiar with it, but Tom, Jerry, Katrina, and Gustav were hearing it for the first time.

Although Flandi's voice was soft, the sound coming out of the speaker was about the same size as Flandi's normal speech, which was actually amplified.

"Very good, not bad, come and replace this with me!" Flandy was more satisfied with this voice, of course, not to mention any bass reproduction, treble reproduction or something, as long as it can be similar to the voice of the person who speaks, it is already very good.

"Hmm!" Candace was very nimble, and in a few clicks she untied the cable of the trumpet speaker and replaced it with the wiring of the medium speaker.

"Hey, hey......" Flandy said casually, feeling that the sound coming from the medium speaker was almost twice as loud as that of the trumpet speaker.

Of course, this is just Flandi's feeling, and there is no sound decibel tester now, so there is no way to accurately measure the sound volume.

Lab Three was large, taking up a third of the entire floor, and anyone in the vicinity of Frandy could hear it.

"This one is good too, Cantis, come on, change this biggest one. ”

"Great!" Candace was very excited to hear Frandy's compliment, and she connected the tuba speaker in three or two clicks.

"Hey, hey, hey! This speaker is so loud. Frandy was standing about two meters away from the tuba speaker, and his ears tingled a little from the shock.

But the sound is okay, there is no noise in such a loud voice, the bass is good, but the treble can't go up, but it gives people a calm feeling.

Maybe everyone in the laboratory has heard the sound of this large speaker, but they don't think anything, but the four Toms who just arrived heard it for the first time, and they couldn't help but rub their ears.

"Hahaha, it's all good, Candace, you've done a great job. "Brandi is very happy that this speaker is already practical, and there are so many applications that can be used.

With that, Frandy prepared to remove the microphone and speakers and install them on the gramophone he had brought.

"Wait, Dean, there's one more test to complete. Seeing that Flandi wanted to remove the wiring of the speakers, Candace hurriedly stopped her.

"Oh, what tests haven't been completed?" asked Frandy curiously.

"Look!" Candace gestured to the four corners of the lab.

When Frandy entered the third laboratory just now, he didn't pay attention because there were too many people, but now he looked at Candace's finger and found that there were four large speakers installed in the four corners of the laboratory next to the roof.

"The problem with the speaker combination has been solved?" said Brandi.

"yes, it's all done, I'll help you plug in all four speakers! Try it out! I'm sure you'll be surprised." Candace said as she changed the line.

"Okay, then I'll try!"

This time, because it was four sets of lines, it took a little longer for Candace to install, but it didn't take more than a minute, and after the installation, she smiled at Frandy and signaled that she could start.

"Hey, hey!" came out of the four corners of Laboratory Three, and Frandy's voice was heard clearly.

It seemed to be back in his previous life when the school was in a meeting, and Flandi's spirit was in a trance.

But it was only a matter of a moment, and he immediately collected his thoughts.

"How's it going, Lord Dean?" Candace smiled as she waited for the compliment.

"Candace, you're doing a great job, what the Imperial Academy of Sciences needs is a talent like you!"

"Hee-hee, I'll just say, of course a smart person like me is coming to the Imperial Academy of Sciences, Abba didn't agree at first!" Candace was in a very happy mood now, and felt that her efforts had not been in vain.

"Alright, Candace, now take the microphone and the four amplifier wires apart. Brandi commanded.

"Ah, isn't it good, why should it be dismantled?" asked Candace, puzzled.

"I've got a new machine, I need your microphone and megaphone to test it, Tom, Jerry, bring the gramophone. ”

"Gramophone?" Candace was stunned, not knowing what Frandy's gramophone was for.

"It's coming!" Tom and Jerry put the gramophone onto Candace's workbench.

Due to the integration of a small magic engine and a small magic power generator, this gramophone is a bit heavy, and when placed on the workbench, it makes a "bang" sound.

The gramophone is about a meter tall and half a meter wide, and there is a glass above it through which you can see the disc made of wax paper.

This time, the scientific researchers surrounded by the Academy of Sciences didn't know what this machine was for, and they all looked at it curiously, and some of them couldn't even see the top of the gramophone.

Since the connectors are already arranged, it is very convenient to install the microphone and speaker wiring, although there is no convenient audio plug, but you only need to wrap the copper wire around the copper pillar of the interface.

Wait for Tom and Jerry to wrap the string and check it again, then nod to Flandy.

Flendy turned on the switch on the speaker, and the microphone and speaker were powered on, making a very slight "rustle" sound.

"Hey, hey!" tried again, listening to the sound of the loudspeakers coming back from the four corners of Laboratory Three, and Romandy felt very satisfied.

Then, he pressed another button on the gramophone's panel, and the wax paper disc under the glass began to rotate slowly, then opened the glass lid and placed a pointer on the outermost part of the disc, and then the glass lid was closed again.

"Fellow researchers of the Imperial Academy of Sciences, you have done a good job!"

Since the speakers are made of paper cones, all the bass effects are very heavy, and there is no tuning or anything like that, so everyone hears that Flandi's voice is a little deeper than the normal timbre.

The "whoa" people applauded when they heard Frandy's appreciation.

It was a good feeling, and Flandi finally knew that when he was at school, the principal liked to talk so much.

"You may not know what it means to have this megaphone, but I can tell you that in the near future, the megaphone will play a very, very important role!"

Everyone knew that this megaphone was very useful, but they didn't expect Flandie to take such a fancy to it, and they all listened carefully.

"Maybe you can't see it yet, but believe me, it only takes a year for it to do something you don't expect, and at the same time, you will be proud to have researched such an epoch-making invention!"
