Rebirth of the 80s New Farmer

Chapter 247 The First Recorder in a Private Enterprise
After going out, Wan Feng got into the broadcasting room again and borrowed Lao Hong's set of electric soldering iron equipment at a price of [-] cents.

Returning to his grandma's house, Wan Feng started his research and creation.

First disassemble the speakers in those broadcast boxes, and after testing proves that they can still work, then use screws to securely fix them two by two side by side in the small box.

He reserved installation positions on both sides of the box.

The small box was divided into three parts by him, with a partition in the middle, so that the place where the speakers were placed on both sides became a small speaker.

It's a pity that there is no professional woofer and can only be replaced by this thing.

He also has a way of making speakers. The pair of speakers he made back then shocked countless people's jaws.

In the previous life, karaoke first appeared in Hongya in the summer of 4000. At that time, a VCD cost more than 1 yuan, and the combined stereo cost more than [-] yuan.

This is not something ordinary people can enjoy.

Around 2000 in 1000, the price of VCD plummeted to about [-] yuan, and the price of non-brand players was around [-] yuan. Only then did they enter the homes of ordinary people.

Karaoke has also become really popular in this small town.

At that time, in summer, there were many people singing karaoke on both sides of the avenue from Yongshi Commune to Hongya County.

A TV set, a sound system and a VCD can be opened on the side of the road.

Anyone can sing a song for two yuan.

Wan Feng, who loves to sing, often goes to sing and spends a lot of money.

Later, I thought it would be better to spend this unjustified money than to get a set to sing how I like at home. Anyway, I have a VCD, so I just need to buy a power amplifier and a pair of speakers.

Action is not as good as heartbeat, so he spent 800 yuan to buy a pair of speakers and a power amplifier.

Come back and pick up a song, the voice is horrible.

The 800 yuan audio combination is simply a commodity thrown on the street. How can the sound be so good?
This is not a problem, Wan Feng can change it himself.

Buy an enlarged version, buy components, and change a transformer. A broken power amplifier that costs more than 400 yuan is turned into a product that is no less than a thousand yuan.

He sold the speakers to a villager in the same village for a price of [-] yuan. He bought a pair of woofers with a diameter of [-] centimeters and a pair of tweeters, and then made a pair with the combined version. Speakers in stage shape.

The sound effect is OK, but there is noise, and when the bass is heavy, the speaker will make a sound of Ula Ula.

The paralyzed Lao Tzu is not what the Soviets want Ulla to do!
The reason was found. The board used to make the speaker is too thin, and it will vibrate and generate noise when it is subjected to the flow of sound waves.

Speakers should be made of composite boards with a thickness of at least one centimeter. He didn't know much about it when he first encountered it, so he bought a board that was only three or four millimeters thick.

This problem is not easy to solve.

It can't be dismantled and redone.

Wan Feng wandered around the street trying to figure out how to solve this problem, but it happened that the highway team on the street was repairing the road and filtering the asphalt.

Wan Feng slapped his head: Yes.

He ran to get some unmelted asphalt and went home.

What are you doing?Isn't the speaker board thin, isn't there vibration and noise!I pour asphalt into the box to see if you still vibrate!

In order to prevent the filled asphalt from falling off due to vibration over time, he nailed some nails on the box, pulled some iron wires on the nails, and finally melted the asphalt and mixed some rosin and other substances that can increase the stickiness. The bottom and corners are all filled.

what's the result?
There is no more noise, and the tone is awesome.

Later, some professionals saw Wan Feng's nonsensical speaker's eyeballs almost flew out: This is so good!

...

Because of his experience in the previous life, Wan Feng is now completely stress-free in designing and making a small speaker.

The speaker is installed, and the tape recorder movement is installed in the reserved slightly rectangular four-square frame, and then the transformer, counter and connection are installed.

After everything was done, Wan Feng took a deep breath and plugged in the power.

The reserved indicator light is on, which means that the power is connected, and there is a slight noise in the speaker.

With slightly trembling hands, Wan Feng pressed the keys on the machine core of the tape recorder, forward and backward, and the playback was normal, only the recording key could not be pressed because there was no tape in the machine box.

Now is the time to witness the miracle.

Wan Feng took out a Teresa Teng tape and put it into the movement, and pressed the play button.

"Sweet honey, your smile is so sweet, like flowers blooming in the spring breeze..."

Although the sound quality sounded average to Wanfeng, it sounded loud anyway.

The tape recorder he made was a success.

Wan Feng let out a long breath of relief.

This thing finally rang, so it was time to beautify the exterior. Although Wang He gave it a layer of varnish to make it look shiny, the bareness was also a bit monotonous.

Why don't you make it look better and sell it to someone?

Wan Feng's tape recorder is considered an experimental product. It does not have a radio or a battery box, which greatly reduces its cost.

When the tape recorder first appeared, the price was thousands of yuan. Wan Feng only planned to sell this pure recording and playback machine for [-] yuan one day. He didn't have to press the radio, but he had to press the battery box.

How can young people carry their hands and shoulders to the street without batteries in the box?How can you show the ratio without pretending?How can you not compare...

Paralyzed without words.

Wan Feng did not deprive others of the right to pretend to be compared, not only did not deprive them of it, but even encouraged them greatly. They did not pretend to be compared to anyone who sold his tape recorder.

The reason why he didn't press the battery box was that he forgot to buy a battery box.

Why has there been several times of forgetfulness recently, it must be influenced by Luan Feng.

Although his tape recorder is definitely not as good as the plastic shell tape recorders that will appear soon, but Wan Feng believes that his tape recorder will definitely crush the opponent in terms of timbre under the same speakers.

Anyway, his wooden shell recorder is designed according to the standard of speakers.

Now he just needs to make it pretty, that is, make a cover for this tape recorder.

Wan Feng was thinking about whether to paint flowers or stickers on the shell. Don't count on stickers now, so he can only design patterns by himself.

After thinking for a long time, I didn't come up with any clues, so I might as well let Jiang Min and Luan Feng design it.

These two goods must be able to design an eye-catching cover.

My uncle and aunt came home from get off work.

Wan Feng quickly turned off the tape recorder and put it in his backpack. He couldn't let them see it now. If he saw it, he probably wouldn't want to take it away.

During the meal, my uncle said that Zhang Hai got an important news at the meeting today.

"what news?"

"He didn't say, he said he would discuss it with you."

He also wanted me to go to Liang Wan's house. Now I don't have time to take care of his affairs, and I'm too busy with my own affairs.

　It's three o'clock!
