When Darren returned to the Burrow and handed the Walkman to the Weasleys' children, there was a burst of cheers, and Mr. Weasley looked at Darren's machine with interest, he had always been curious about Muggle objects, and had never seen such an amusement device.

However, after a while, Mrs. Weasley was alarmed by the voice, looking at the WM-EX1 in their hands, Mrs. Weasley hesitated for a moment, but still said that she could not accept Darren's gift casually, so that everyone around her looked at Darren nervously with disappointed expressions.

Of course, Darren would not change his mind, so he told Mrs. Weasley that Fred and George's share was to thank Fred and George for their help in his transformation of the MiG-29, and as for Ron and Ginny, they were just stained with the light of their brothers, and the mall bought one get one free big promotion, and in addition, there were no returns......

Eventually, at Darren's insistence, the twins and Ron and Ginny finally left a gift for them, and after Darren explained how to use it, they unpacked it and couldn't wait to put it on tape to experience it.

"It's amazing, I can't believe Muggles can make such interesting machines," Fred, who was wearing headphones, shouted loudly, startling Mrs. Weasley next to him, "Oh, Fred, why are you so loud?"

"Huh, what did you say?" Fred asked aloud, still looking at Mrs. Weasley.

Darren hurriedly went up and took off one of Fred's headphones so that Fred could hear his own voice, and sure enough, his voice was much lower now, "What did you just say?"

"I mean, why are you so loud!"

"No?" Fred looked confused.

"He wears headphones in both ears, which is why he is so loud, as long as he takes off one of the headphones when he speaks, it will be fine. ”

As they spoke, George was looking at the cassette over and over again, and suddenly said to Darren, "Is the sound stored in these, in the cassette?"

"Strictly speaking, on these tapes in the cassette, the fluctuations of the sound are recorded by writing the magnetic material on them, and then the sound can be heard after the reading of the magnetic head," Darren briefly introduced, and suddenly saw Fred also take off his headphones, leaned over, and stared at him with bright eyes with George, which startled him, "Oh, what's wrong with you?"

"If we add this to the magic camera, it will definitely be more popular. ”

At this time, Darren remembered that the magic camera they made before could only record images, no sound, or silent films, but it was relatively simple to transform with a magic telescope, after all, the basic effects are in the telescope, but to make a magic tape recorder, it seems that there is no such thing.

Darren only remembered the magic radio he had seen at the Weasleys' house, the PA system at the Quidditch arena at Hogwarts, and the campus radio system he had tinkered with Fred and George......

"You mean?"

"Of course, you must remember the radio we installed at Hogwarts the year before. ”

"But it can only amplify the volume and transmit, and it doesn't have the function of recording sound. ”

"It's okay, we can first follow the camera method, first use your broadcast system to assemble the recording and playback system, and then slowly explore, I think the basic principle is similar, we have a lot of equipment that can be used on this when we study the camera, and we will be able to succeed very quickly." ”

"Yes, let's go, we'll go right away, I've already thought of a plan!Mom, we're not coming for dinner, just bring us some sandwiches later, preferably not bacon." ”

Although the twins were talking to Darren, they actually got up and went straight into the room where the camera was being studied, leaving the rest of the people looking at each other, and seeing their energy, it was estimated that they would have to stay up all night tonight......

Mrs. Weasley sighed again that if only they could have worked so hard when they had studied before, Mr. Weasley patted her with his hand and said slowly, "Maybe this is the life they like, and it is the life that suits them!" Mrs. Weasley nodded slightly.

At dinner, Darren told Mr. Weasley about his desire to buy a company that produced magical telescopes, after all, the other party had far more connections than he, a Muggle-born Hogwarts student, and gave Mr. Weasley a check from Gringotts to give him carte blanche to do so, and Mr. Weasley said that he would do his best to help.

Before they had finished eating, they suddenly heard the twins shout loudly, "We succeeded!"

So fast? It's too rebellious, the people around the table will be suspicious, and they will walk out of the kitchen, and as soon as they get out, they will see Fred and George running over, and they will shout and hug everyone, "We made it, it's incredible." ”

"So fast?" Darren still couldn't believe after hugging them.

"Actually, we've already done it, we just don't know it. ”

"Yes, in the past, when we were modifying the cameras, we found that there were no images recorded in the memory, and we thought it was a problem with the camera, but this time we were going to test the system, so we installed the memory and planned to make the most of it. ”

"As a result, when we connected the recording and broadcasting equipment, the sound came out of it, and the memory actually worked normally, but they recorded the sound. ”

"Yes, what we needed was to have a recorder on the camera so that we could record the sound while shooting the image. ”

Well, now the wizarding world has moved from the silent film era to the sound film era......

That night, Darren and the twins tried to transcribe the sound from the cassette into the magic memory, so that they could hear the music when they arrived at Hogwarts, but unfortunately, they couldn't solve the problem of signal conversion after discussing it for a long time, after all, electronic devices and magical devices are really not the same style of painting, and magic signals can interfere with electronic devices.

In the end, they felt that there was only one way to convert the sound message. The sound is played out by a playback device and stored with a magic recording device, just like a transcribed audio tape long ago......

After Fred and George unexpectedly solved the sound problem, it became increasingly urgent to form a company that produced the Magic Camera, as the Quidditch World Cup was about to begin, and Mr. Weasley said that he had already obtained some of the best tickets through his connections in the Department of Magical Sports, which were definitely the best promotional materials to open up the market if they were shot from.
