Siheyuan: Xu Damao, I want to go to the moon

In fact, the earliest tape recorder was the phonograph, the one that the leader gave to Sha Zhu in the original drama.

Let’s not talk about whether it is classical or not, this thing is inconvenient.

The phonograph was invented in 1877 by Edison, the world-renowned inventor. It was considered one of the three most exciting inventions of the 19th century. Ten years later, Edison improved it, and the phonograph became widely popular. Although the phonograph achieved the function of recording, it mainly used mechanical principles to reproduce sound, and the recorded sound volume was low, so it was necessary to shout loudly into the speaker when recording. Even so, the phonograph can be regarded as a major historical breakthrough.

Then, Danish scientist Paulsen used the principle of residual magnetism to make a "recorder" with piano wire - that is, an early magnetic recorder - and obtained a patent in 1898. Later, it was used on ships and used to record Morse code during World War I. However, this kind of magnetic recording requires high-quality steel wire and steel belt, and is bulky and inconvenient, which greatly affects its popularity.

Then came the wire recorder, and in 1935 the magnetic tape.

In 1951 and 1953, Zhongsheng Electric Works in Modu, China, produced the first steel wire recorder and magnetic tape recorder in China. In 1963, Philips of the Netherlands invented the cassette tape, and cassette tape recorders quickly became popular in households.

In other words, magnetic tapes for recording have actually been around for a long time, and proper cassette tapes and home recorders should have appeared and been on the market around 63.

Then came the cassette recorder, which was improved in 63 and widely used in cars and ships.

In 64, portable tape recorders were invented, which are now called cassette recorders. In 66, home cassette recorders were invented...

And it's only 60.

Xu Damao decided to quickly seize this market.

After taking some time off, Xu Damao asked for leave again to go field research. This time Li Huaide was dissatisfied. He said that there was no problem in approving your leave, but you were nowhere to be seen all day and had no works.

You Fengxia came to Xu Damao some time ago, wanting to buy some more songs from him. After her National Day performance last year, she is now a well-known young singer. But if there is no new work for a long time, it will cause controversy.

There are quite a few people who write songs in major music schools and art troupes, but compared with Xu Damao's previous songs, those songs are completely different.

Finally, Xu Damao had no choice but to adapt the "Ode to the Red Plum" that he had saved from before to make it suitable for her to sing. However, the background of the song was difficult to explain. After all, the opera "Sister Jiang" was not released until 64. If it was performed so early, it would conflict with the opera.

If someone asks you to explain the backstory of the songwriting, what do you say?

Then Xu Damao promised to give her something fun to play with after a while, which would be more interesting than writing songs. Only then did You Fengxia let Xu Damao go.

She also threatened Xu Damao that if she was not satisfied with the good thing, she would bring her former teachers and senior and junior classmates from her previous school to visit the great artist Xu Damao - which scared Xu Damao terribly.

Once the professionals arrive, it will be easy to be exposed, and that won’t be acceptable.

The tape recorder must be found as soon as possible to divert their attention.

With this thing, they will be busy singing and recording songs all day long, so they won't have time to write songs.

Moreover, Lou Xiao'e has been annoyed recently. The little kids must have her sing lullabies before they go to sleep. Using a phonograph is not enough, it must be Lou Xiao'e's voice. She also asked Xu Damao to get a tape recorder as soon as possible. She had said it a long time ago that she had not had time to do this.

So on February 60, 2, Xu Damao was transferred to Hong Kong, and using the equipment there and his own optimized drawings, he produced the first single-slot tape recorder.

Recording, playing tapes, receiving FM radio, can connect to microphone, legendary headphones, legendary subwoofer, the body comes with anti-noise microphone, left and right stereo subwoofers... the main feature is full compatibility!

It has all the basic functions and is about the size of a later portable painting box or tool box. It can be powered by batteries or directly connected to a power source. There is an antenna and a carrying handle on the top, so you can carry it to the suburbs to record or play songs, but it consumes more battery - multi-scenario applications!

The whole body is black with some silver, and there are also several styles with dark red and sports blue. The surrounding is wrapped with calfskin to reduce resonance and prevent collision - three color combinations of fashion, retro and sports!

It can be said that as soon as this product came out, the whole world was shocked!

There are tape recorders in the world, but they are all too large and bulky. The one designed by Xu Damao is actually also very large, but it is for home use.

He plans to sell this model for a while, and when imitation and copycat versions appear, he will release a dual-card slot model that can play and record at the same time, and can transcribe tapes at home without playing sound. When that model has sold out, he will continue to miniaturize it.

After the legendary tape recorder has a stable market share, we will then proceed to develop ultra-miniaturization, that is, the development and launch of the Walkman. We also need to study sound quality, noise reduction, portable microphones, headphones with microphones, etc.

The main target is to be a copycat. As long as you copy and imitate, I will immediately launch a new product and always occupy the first place.

When everyone’s skills are similar, I will lower the price!

Once the price comes down, I will update the exterior design!

I can’t kill you!

Legend is number one, there is no room for negotiation.

On February 2, the Legendary tape recorder (home use) was directly launched on the market. All the publicity and promotion work was arranged by Lou Yufan. 20 commemorative signed and numbered editions were handed over to the Hong Kong Auction House and sold at a sky-high price of more than 100 million Hong Kong dollars. The Hong Kong radio station, many wealthy businessmen, and audio companies from all over the world donated the money directly to charity. The official launch price of the Legendary tape recorder (home use) was US$400!

Then, the scalpers got busy again, it was time for them to make big money!

Legend Audio Factory has added a tape factory. The price of blank tapes is set at US$10 per box. However, it is estimated that the price will gradually come down because the cost is not high.

Xu Damao didn't care about the sales issues of the Hong Kong factory. Anyway, Lou Yufan would take care of the patents and intellectual property rights. There was a special legal team there that would not let Xu Damao suffer any loss. The tape recorder made money much faster than the speakers. It wasn't just making a fortune, but directly producing gold!

Xu Damao didn't care about all that. He took 10 machines and 100 tapes and returned to Beijing.

Of course, the Crescent Moon Legend Audio Factory will also mail about 100 units to the embassy where Li Mingmei works through formal channels. As for who Li Mingmei will give them to, that is her business. The school where she studies will donate some, and the Ministry of Foreign Affairs will donate some, and the rest will be decided later.

Xu Damao also registered and recorded these things at the Yangcheng Border Management Office (Customs), and with the documents from the embassy and the speaker factory, they were quickly released.

When they arrived at the courtyard and took out these things, the women went crazy!
