The goal of this presentation is to explain the function of and physics behind the average speaker; showing that this ubiquitous, seemingly complex device is actually incredibly simple.

The physics covered will be the basic principles of sound waves as well as electromagnetism. The build will consist of creating several speakers of increasing simplicity using only paper, copper wire and permanent magnets.
