Physics speaker project...

So, for physics, I have a group project assignment of building a speaker from household items... :rolleyes:
I still don't know if there is a size or dimensional limit or requirement, but I'll edit this post if there is...
Well, the speaker obviously is going to have two magnets, and a coil... But what to do with these is still in question... I was thinking of taking a paper cup, putting a magnet taped on the bottom, and then have the coil hover on top of it on the wider portion of the cup... So the cup can be set like a normal cup with liquid inside would be sitting... Then, put cyran wrap or aluminum foil, so that it closes the air on top of the coil, and put something pointy on the surface...
I dunno if that was exactly descriptive enough, but... yeah...

Dude, the hardrive thing is sick!! Hehe... Imma try that...
Edit: Does this mean I can make sound through a motor too? And also, is it safe for me to power my contraptions through my JVC receiver?
