Electricity from Sound
In some cases if done right devices can be use backwards to give energy than putting in energy, or other useful purposes. I assume most know some things like a motor that if you put energy you get it to rotate, but if you rotate it it gives energy.
The same thing with sound speakers or microphones how you have electromagnetic induction going on but, the thing is that it is not tweaked to be sensitive enough to get energy from it.
So the question is how would one go about making something like that to be very sensitive to give off energy? I have a few assumptions but what would be your way of doing it to be able to speak or put it next to a noisy device and get energy and efficiently?
Wouldn't a more powerful magnet not work since it would need a high sound waves to make the film on the magnet or coil to move?
Would it need to be sealed in helium to get less friction?
Would it need a funnel?
Would the coil need to be longer and narrower?
Would it need a leverage so that the magnet is on the short part of the focal point that moves in the center and the long part is on the diaphragm. That way a little goes a long way easier.
PS. Notice how the noise increased when you have 2 phones talking to each other together while next to each other to get feedback? It seems like Constant energy + Compounded energy = multiplied energy.hmmm
