Buzzing sound in speakers
Permalink   
 

I wanted to create a simple stereo system. So I bought an audio amplifier circuit from the local market, which works very well. The only problem is the continuous buzzing sound. The noise is quite loud. It increases as I increase the volume. But it disappears as soon as I touch the radiator of the amplifier. Therefore, I soldered the entire metal body of the bass, treble, volume potentiometers and even the radiator to the negative terminal. This reduced the problem to a small extent.
What else can you recommend?

it seems to me that the whole problem here is that one of the wires is loose and it gives a short circuit

Here, most likely, it's about the wires with which you connected all the elements. Some wire is poorly soldered somewhere, and it gives this sound. You can also read the article on thehifiguide.com to figure out other reasons of this sound. I'm not a pro in electrical engineering, but it still seems that it's about the connecting wires. You can take a picture and send a photo here so that I can better understand how it all looks and what the problem may be. So if you write something, it will be interesting to find out what gave this sound
