I'm not so much interested in the Heatâ†'Sound part as I am the Soundâ†'Electricity.
Does anyone know where there is more info about Soundâ†'Electricity?

This is a relatively simple idea - you just use a speaker. and sound hitting the speaker will cause it to generate electricity - it will act like a microphone.
Does anyone have more in depth information on this device?
