Re: sound to electrical

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.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
