This is how a microphone membrane works. Have you researched this yet? Are you looking for any particular application?

As well as the microphone Tormod mentioned, any loudspeaker will also produce electricity from sound. Connect the terminals to a voltmeter and shout your lungs out.

Just ran across a Gallery image of a new device that converts sonic energy into electricity.
