Music to my ears!

Sitting at home, doin my homework, listening to music. Normally not very interesting. But then I realize that the music that I'm listening to actually has a lot to do with physics. Then it dawns on me how smart these inventors and engineers must be to create my ipod or any other musical object. First of all, the only way I'm actually able to hear the music is because in my ear buds, i think, there is a tiny little membrane with metal attached to it and very close to it is a magnetic. When the ipod sends electrical signals to the magnetic, varying the strength, i guess, of the magnet, it causes the membrane to vibrate. The vibrations create sound which comes into my eardrums which also have membranes which vibrate and I pick up these vibrations and my head turns them into audible sounds and lyrics like "Aaahh eaaahh suddenly you remember! Baaeeeahhh dancing in September! Yeaaaaaahhhhh!!!!" Of course, my ipod allows me to change the volume, or in scientific terms, the amplitude of the music, however this causes the vibrations from the ear buds to become stronger and these stronger waves created not only wear out the ear buds faster, but can also damage my ear drums. Too loud and not only will it feel intensely painful, but once my ear drum blows, it basically cuts off hearing to my ears. For now, I guess I'll just turn down my volume, even though I don't really want to hear myself sing. Actually i don't know if anyone really wants to hear me sing..."Pump it! Louder! Pump it! LOUDER!!! Pump it! LOUDER!!!! Turn up your radio! Blast your stereo!!!!"
