I have a few broken cellphones, and I scraped 2-3 and never realized what the mircophones were. I just thought they were some inductor, (with a curious piece of plastic from the outside over it, I kind of thought it was RF related)
Until some little electrek mic's arrive I might try to get a mic from a phone working. Just for basic experiments with transistor's or say a LM386, what amount of AC current/voltage should I be appling to 1 of these? I'd say they are all pretty similar, and I think they are classic mic's, as in just a coil of wire around a magnet.
