Comment on Do smoke detectors have little speakers inside them? If yes, would it be possible to hack them to play a little jingle?

You can also make hard drive heads play music. Poor quality music, but music.

Multiple piezoelectric buzzers could probably play a tune if you tune them to individual notes. Not sure how to tune them, but probably cutting them, or putting bluetak on them would alter their note.
