Take Apart Speaker

A wire and magnet connected to a cup
PIRA: 5H40.37

The take-apart speaker consists of a neodymium magnet and two plastic cups, one of which has a coil of copper wire glued to the bottom.  The speaker is made by nesting the cups together with the magnet between them and the wired cup on the bottom.  Music is played by connecting the two free ends of the wire to an amplifier with music input.
