Just discovered something and would like to share it with the class. I was just playing with random things and happened to connect my 5W amplifier to an AC motor. As i said random. Nevertheless i discovered that not only speakers can reproduce sound. The AC motor seemed to produce a very low volume sound and tremble at low frequencies. Seems like the coils inside it make it a perfect resonator for these things. Seems to have an excellent frequency response from 1Hz to 20Khz. Just found it interesting.

put a DC motor on it and then put the motor in a cup and put a CD over the top of the cup

It is industry standard to use stepper motors and split up the frequencies. Like subwoofer, mid sub, mids, tweeters.

Well in the 1980's rave scene it was standard practice to use washing machine motors inside a bass horn cabinet. I have never heard of using stepper motors to split frequencies. With all due respect this sounds like a load of dingos dung.

I've also never heard of splitting frequencies with an AC motor but come to think about it the motor seemed to respond quite well to very low frequencies (1Hz-100Hz) and not so great with higher ones ao i guess there can be some limited separation but filters are better.

Yep, a magnet will vibrate in the presence of an alternating magnetic field. It can also be used as a microphone. As for the Rave trick I don't know but I remember a lot of weird innovations being tried.
