Speakers can cost hundreds of dollars to go with an awesome sound system but you can make your own as well. In order to do so you just need to learn the physics behind doing so. First electrical energy from the ipod tranfers and converts into magnetic energy which then converts to sound waves and hit against our ear drums which then converts again so we can understand them. A simple speaker can be made using a business card, wire, aux cord, a bowl and a magnet. Once you set everything up the cup in the bowl creates a louder noise and the cylindrical paper makes the noise clearer. Vibration moves up throufh the cords to the paper dishes and helps create sounds. To make everything sound better its usually better to put it on a very solid object for something to vibrate against. So next time you need a quick fix for a speaker, just use household objects.
