Electrostatic loudspeaker equipment has bias voltage applied between oscillator electrode and fixed electrode

摘要

The loudspeaker equipment has a fixed electrode (20a,b) and an oscillator, or vibrator (40) associated with the respective fixed electrode at identical spacing. A control signal is transmitted to the fixed electrode. A bias voltage, applied between an oscillator etc. electrode and the fixed electrode, enables the application of a drive force to the oscillator, corresponding to the control signal. The fixed electrode is divided into numerous electrode pieces (21a,b) for control signals of different voltages.
