Theoretically, I know it is possible to drive a microphone "backwards" to deliver signals similar to earphones. I am planning some experiments for which such a method of delivering signals would be very desireable. Has anybody used mics in such a way (and what were the mics) and what are the consequences and limitations (i.e. frequency response, dynamic range, input impendence problems, etc). Cheers, Daniel J.
