Picture of Pringles Can Speaker
Pringles occasionally run a promotion where you get a speaker for the can. But why bother with all that, when you can make your own speaker from the Pringles can.

ok, so how does this work? driving an audio signal into the magnet coil causes an oscillating magnetic field around the coil, correct? i'm guessing there's some kind of movement induced by that in the magnets. but, the batteries are stuck to the metal base, and therefore cannot move, right?

This is a simple speaker and works similar to any other, it is the coil that moves. There are no batteries in this design, they are a stack of magnets.
oops, i meant magnets, not batteries. Ok, so the MAGNETS are not moving, only the voice coil. So the coil (and the paper tube it's attached to) moves due to its magnetic relationship to the magnets. That in turn causes air to oscillate within the tube, kinda like a piston? That vibrating air in turn causes the plastic lid to vibrate. Right? thx
