Converting from sound to electrical energy?

  1. Nov 25, 2005 #1
    Hi, I have this topic for a science fair that involves converting sound energy to electrical energy.

    Is there any simple way to do this? I tried googling, but ended up getting methods that I can't possibly do.

    Any help is appreciated. Thx.

    Look into how a microphone works. Perhaps more interesting than a basic microphone, a specific, relatively new type uses piezoelectric polymers - google them.
