If you're looking to use a Piezo, try this search result, and look at the related Instructables on the pages.

Piezoelectricity is the property of some crystalline materials to produce a voltage difference across opposite surface as a result of applied pressure (techinically, applied stress).

In your case, walk into any decent electronics store and say to the sales person what you wrote above.
