If music for you is not just a combination of sounds and notes, then you just need a device such as an amplifier for a speaker or subwoofer. Thanks to this device, true connoisseurs of music set the speaker in such a way that any melody sounds fabulous and fascinates every second more and more. And it’s not necessary to run to the store and spend money on its purchase. Just make an “amp” with your own hands. How exactly, let's figure it out.
How to make a sound amplifier with your own hands? Making the body
First, you need to prepare a case in which the entire electronic device will be protected from various mechanical damage, moisture and other negative environmental influences. Since we mentioned damage protection in the above list, this part will be made of metal, and in order not to burden the device, you can use several aluminum corners. After that, cut the workpieces and make vertical racks. As for the sizes, the thickness of our amplifier will be about 5-6 centimeters, while the dimensions of the glass cover are 4x1 millimeters. The height of the entire rack is about 5-5.2 centimeters. When constructing an element case, do not forget about the horizontal elements of the frame. As the connecting elements in the assembly of the structure, 3-4 screws should be used, preferably the M3 series. In this case, it is necessary to make two angles on one of the racks, the bottom and the back wall. To do this, you will need a metal jigsaw and a 1.5 mm aluminum sheet. All this is then also attached to the structure with screws.
Also in the question "how to make an amplifier for speakers", you need to pay attention to the front panel. To make it, take a strip of aluminum 5 mm thick and make a bar that will hide the entire mechanism. To give the device a “human” look, paint it with some kind of paint in an aerosol can.
Pay
If you want to learn how to make a sound amplifier with your own hands correctly, remember that the main thing in it is not the case (although it also plays an important role in the design), but the board. And if in the first case several errors can be made, then each mistake in the design of the second mechanism can significantly affect the performance and sound quality of the speaker as a whole. How to make a sound amplifier with your own hands? The switching board is made as follows:
- The laser printer prints a picture of the future board with a 1 to 1 scale.
- The back of the image paper is placed on a piece of fiberglass (it is important to degrease it before).
- The result is transferred to a foil, which is then smoothed by a glowing iron with the temperature regime set to the maximum value.
- After 5 minutes of processing, the board cools, and the paper is removed with water. Along with this, the toner will melt and adhere to the foil.
Last stages
After that, you need to take care of the board for capacitors and insulation. At the final stage, the question of how to make a sound amplifier with your own hands is accompanied by the removal of the device’s control knob on the front panel. After it is fixed there, you can enjoy the melodic sound!
