How to make your own speakers
Find copper wire, packing tape, and a strong magnet.

+ Find copper wire, as you can use flint, water, motor oil, or solvents, and an insulated or ceramic plate. Tin and plastic plates are another great choice..
+ Some experts recommend spending most of your energy on this magnet. Aside from asking for a shrink-wrap, you could also buy cheap ones that either come pre-wrapped, or you can purchase a free industrial magnet making kit online..
+ This current makes the magnet vibrate, and those vibrations are picked up by our ears as sound. To hear the sound well you should also get a small plastic tupperware or cup..
+ The magnet goes through either around the loops of the microphone wires or in other areas of the dock. There are hundreds of ways to charge your speakers..
