A speaker is a device that allows you to make the sound louder and clearer. There are more and more lovers of good sound, but not everyone has the opportunity to make music a little louder. For example, if you are in the country, do not go to the city for the columns, and in the city you still need to find and buy them. There is no need to travel somewhere and throw out money for items that can be made with your own hands.
If you have not skipped physics classes at school, you should know that a regular speaker consists of a permanent magnet, mainly neodymium and a copper coil. When an electric current is applied to a copper coil, an electromagnetic field arises around it. When a magnet is placed in this constant electromagnetic field, either the magnet itself or the coil begins to oscillate and transmit the vibrations to the membrane. After these actions, the sound is obtained. This simple design allows us to hear a clear, and most importantly loud sound.
First, let's watch a video:
To make the simplest model speaker on paper, you will need:
- paper (square sheets for writing are suitable);
- nail scissors;
- aluminum tape;
- stapler;
- permanent magnet.
Aluminum tape is sold in any plumbing store. It is necessary for the dismantling of pipes, and we will use it for our speaker.
First, we cut thin strips of aluminum tape. After we cut out the stripes, we tear off the sticky side and glue it with a snake on a square leaf. The main thing is that the strip does not come into contact with each other, otherwise nothing will work.
Now we tear the sound device, in our case it is a computer speaker and with the help of a stapler we attach it to a leaf with aluminum stripes. It is advisable to strip the wires.
Next, put a piece of paper with a snake in the form of aluminum tape on a permanent magnet.
The same thing can be done not with aluminum tape, but with wire. We attach the wire to a piece of paper using ordinary stationery tape. Only adhesive tape needs to be fixed in small pieces at a small distance.
It is important that nothing is in contact or intersect.
Now we need to carry out the same actions that we carried out with aluminum tape and bring it to the magnet.
Since the paper does not fluctuate much, it will not work to achieve bass, only normal sound.
And here is another design reinforced tape dynamics.
