Cup Speaker

There are lots of designs of this, especially ones that use paper plates and suspensions. They all seem much more complicated and finicky for barely any more sound. This http://www.exo.net/~pauld/activities/magnetism/speaker.html from Paul Doherty of the Exploratorium seems to work the best, especially for the novice.

Those which use paper plates and suspensions are superb.
