Abstract
PURPOSE:Movements of a diaphragm are detected by so arranging the circuit that the change in the electrostatic capacity formed between an inner fixed electrode and an outer fixed electrode is converted to an electric signal and that this signal is fed back to the input circuit of a power amplifier which drives a speaker.
