As soon as he left the house, Wan Feng went back into the broadcasting room and borrowed Lao Hong's electric soldering iron equipment for 1.3 cents per pack.
After returning to his grandmother's house, Wan Feng began his research and creation.
First, remove the speakers from the radio boxes. After testing and proving that they are still working, use screws to firmly fix them in the boxes in groups of two, side by side.
He reserved installation positions on both sides of the box.
He divided the box into three parts, with a partition in the middle, so that the places where the speakers were placed on both sides became a sound box.
Unfortunately, I don't have a professional subwoofer so I can only use this thing instead.
He is also good at making speakers. The pair of speakers he made back then shocked countless people.
In the previous life, karaoke first appeared in Hongya in the summer of 1993. At that time, a VCD cost more than 4,000 yuan, and a combination of audio systems cost more than 10,000 yuan.
This is not something that ordinary people can enjoy chatting about.
By 1999, around 2000, the price of VCDs had plummeted to around 1,000 yuan, and generic brands were around 800 yuan, making them accessible to ordinary people.
Karaoke also began to become really popular in this city.
At that time, when summer came, there were many karaoke singers on both sides of the avenue from Yongshi Commune to Hongya County.
All you need is a TV, a set of speakers and a VCD to open a shop on the roadside.
Two yuan to sing a song, who will sing it?
Wan Feng, who loves singing, often goes to sing and spends a lot of money.
Later I thought it would be better to spend this money to buy a set of my own and sing whatever I want at home. Anyway, I have VCDs. I just need to buy an amplifier and a pair of speakers.
Action speaks louder than words, so he spent eight hundred yuan to buy a pair of speakers and an amplifier.
When he came back to sing, his voice was horrible.
An 800-yuan audio system is basically something you throw away on the street. How good can the sound be?
This is not a problem, Wan Feng can change it himself.
He bought an amplifier, components, and modified the transformer. A broken amplifier worth more than 400 yuan was transformed into a product that was no less than others worth over 1,000 yuan.
He sold the speakers to a villager in the same village for 100 yuan. He used the money from selling the speakers to buy a pair of 20 cm diameter woofers and a pair of tweeters, and then used the combination version to make a pair of stage-style speakers.
The sound effect is okay, but there is some noise, and when the bass is heavy, the speakers make a rumbling sound.
Damn it, I’m not a Soviet, why do I need Ula!
The reason was found. The board used to make the speaker was too thin. When it was affected by the flow of sound waves, it would vibrate and produce noise.
The speakers should be made of composite boards that are at least one centimeter thick. Since it was his first time, he didn't know much about it, so he bought boards that were only three or four millimeters thick.
This problem is difficult to solve.
You can't just tear it down and rebuild it.
Wan Feng wandered around the street trying to think of a way to solve this problem. Coincidentally, a road crew was repairing the road and filtering asphalt on the street.
Wan Feng slapped his head and said: I got it.
He ran to get some unmelted asphalt and returned home.
What are you doing? Aren't the speaker panels thin? Won't they vibrate and make noise? I'll fill the cabinet with asphalt and see if you still vibrate!
In order to prevent the asphalt from falling off due to vibration over time, he nailed some nails on the box, pulled some wires on the nails, and finally melted the asphalt and added some rosin and other adhesive substances to fill the bottom and corners of the speaker.
What is the result?
There is no more noise, and the tone is great.
Later, when some professionals saw Wan Feng’s nonsensical speakers, their eyes almost popped out: This is actually possible!
…
Because of his experience in his previous life, Wan Feng now has no pressure in designing and making a speaker.
After the speakers are installed, the tape recorder movement is placed in the reserved slightly rectangular box, and then the transformer, counter and wiring are installed.
After everything was ready, Wan Feng took a deep breath and plugged in Lingyuan.
The reserved indicator light lights up, indicating that the power is on, and there is also a slight noise in the speaker.
Wan Feng pressed the buttons on the recorder with slightly trembling hands. The forward, reverse and playback were all normal, except for the record button which could not be pressed because there was no tape in the box.
Now is the moment to witness the miracle.
Wan Feng took out a tape of Teresa Teng, put it into the mechanism, and pressed the play button.
"Sweet, your smile is so sweet, like flowers blooming in the spring breeze..."
Although the sound quality sounded average to Wan Feng, at least it was working.
The tape recorder he made was a success.
Wan Feng breathed a long sigh of relief.
This thing finally started working, so the next step was to beautify its appearance. Although Wang He had painted a layer of bright paint on it to make it look shiny, it was still too dull and monotonous to be bare.
Who would you sell it to if you don’t make it look good?
Wan Feng's tape recorder is an experimental product. It has no radio or battery box installed, which greatly reduces its cost.
When tape recorders first appeared, the price was over a thousand yuan. Wan Feng only planned to sell this purely recording and playback machine for three hundred yuan. He could skip the radio, but he had to include the battery box.
How can young people, without a battery case to hold batteries, carry them around on the street and show off? How can they show off their cool without showing off? How can they…
I'm so confused that I'm speechless.
Wan Feng did not deprive people of the right to show off. Instead, he encouraged them greatly. They didn't show off to anyone, so he sold his tape recorder to them.
The reason he didn't press the battery box was that he forgot to buy the battery.
Why have I been losing things so many times recently? It must be because of Luan Feng's influence.
Although his recorder certainly couldn't match the plastic-shell recorders that were about to appear, Wan Feng believed that if it were used with the same speakers, his recorder would definitely surpass the others in terms of tone quality.
After all, his wooden-shell recorder was designed according to the standards of a speaker.
Now he just had to make it pretty, which meant making a cover for the tape recorder.
Wan Feng was thinking about whether to draw flowers or put stickers on the shell. Since he couldn't count on stickers now, he could only design the patterns himself.
After thinking about it for a while, I couldn't come up with any idea, so I just let Jiang Min and Luan Feng design it.
These two guys can definitely design an eye-catching cover.
My uncle and aunt came home from get off work.
Wan Feng quickly turned off the recorder and put it in his backpack. He couldn't let them see it now, otherwise they would have no chance of taking it away if they saw it.
While eating, my uncle Zhang Haijin received an important piece of news during a meeting.
"What news?"
"He didn't. He wants to discuss it with you."
He wants me to go to Liang Wan's house again, but I don't have time to deal with his affairs now. I am too busy with my own things.
