Hello friends! Today I will try to answer the question of how sound is created in a Tesla coil. You've probably seen a lot of sounding Tesla coils. I also made my own reel, which not only plays a polyphonic melody, but it can also sing in the voice you just heard. There is interference, but it reproduces the voice. The question of sound is very complicated. I can only say approximately how the Tesla coil creates sound. So, this phenomenon is related to the phenomenon of self-induction. More specifically, it can be said that if you have a half-bridge oscillatory circuit and break the circuit of the half-bridge oscillatory circuit, then the energy of the electric circuit is released at the moment of opening the circuit of the half-bridge oscillatory circuit. If you break the electrical circuit in time with the sound frequency, then the discharge streamer changes. The streamer can be short but thick, and long but thin. If you change the thickness and length of the streamer in time with the sound, then the plasma oscillation in the air will create longitudinal waves, which you and I hear as sound. If you want to learn how to make this device that you have seen, then I have written an article that you can purchase in my store using the link that I will leave in the description of this video:

So, that's it for now. Up to new ideas, up to new projects. Sincerely, Yuri Kovalenok
