How tiny is tiny? Diameter/depth? And what frequency range are you looking for?

If it's over 5kHz, you can use a Piezo element. Low power requirements make it an easy choice if you want to reproduce sounds like you'd get out of a greeting card, and driving it directly from a low power headphone-level amp (like an LM386).
