Constructing a homemade speaker

It's a simple speaker that can be built at home from inexpensive and freely available materials: magnet, cardboard and tape, isolated wire from signal transformer and mini-jack cable from broken headphones.

Above is a sample taken from this speaker. In real it's really quiet, but its sound quality is pretty good ;)

An homemade inductor with ~80 wire loops was connected it into mini-jack cable.
