Is the principle of microphone a generator

If you remember that "condenser" is an old-fashioned word for a capacitor, you can probably guess how a condenser microphone works: much like a capacitor! 1. Incoming sound waves carry energy into the front of the microphone. 2. The sound waves hit a flexible diaphragm, which is actually one of the plates.
