I was a hobbyist. I was a hobbyist and have such ideas had. I built the first microphone. There were only carbon microphones. They've rushed. And a noise-free microphone to have had to build a microphone. And since there have been opportunities. There have also been descriptions and stuff. It has even given books, descriptions of how to build such a thing and so on. This has been - I've already read, but I could not amal this because that was too expensive. Since I'm me everything ourselves. Such a microphone is simply yes. There is indeed nothing special. It is a membrane inside or two or three membranes, depending on how the build is. And is there a magnet and a coil vibrates as a magnet inside.
