Watching some very large speakers at work, I was wondering if the speakers themselve could be used to launch a projectile. the idea is that I apply a powerful DC current to the speaker to make it come inwards to the magne, the suddenly I apply a GIANT pulse of the opposite polarity to the speaker, making it pop forward at high speed. do this with a light projectile on the cone surface, and I may be able to launch the projectile, with an added sound to it.
I know that, given that this isn't a completely absurd and unrealistic idea, I would need a HUGE speaker, and a large DC power source. I just want to know if this would ever be possible to achieve.
or, on a very related subject, I could take the coilgun that I've been trying to get working, put a long permanent magnet inside of it, and when I engage the electromagnetic coil, the magnet jumps up to the coil, and then when it gets to the coil, it stops abruptly and any tiny nonmagnetic projectile that was resting on top of the magnet is flung forward.
please tell me if you like any of these ideas and if they have even a snowball's chance in hell of working.
