• Ionophone - Singing Arc

    Now I will tell you how to do it with my own hands "Ionophone" or as it was called "singing arc". Actually by the names you can already guess that the ionophone is the source of sound. The sound in this device comes from a burning arc, the timbre of the sound varies with the frequency of voltage generation. In the 50s of the last century, these devices have found practical application, but now there are many more effective  alternativestothisdeviceandhaveforgottenaboutit,andwecanassembleitonlyasatoyforinterestingexperiments.
