- | For some, the electrical concepts behind speakers may seem to complex to comprehend, but it actually uses a fairly simple concept involving vibrations of air molecules. In order to make these vibrations, a cone is set up like the one pictured below. When an alternating current is provided through the coil, it creates an electromagnetic field that attracts and repels from the magnet positioned opposite of the coil.
