Abstract
An electrostatic speaker is constituted of upper/lower electrodes, upper/lower cushion materials, and a diaphragm. Cutouts are formed in the upper/lower electrodes, upper/lower cushion materials, and diaphragm, wherein they are shifted in position such that a part of the diaphragm and a part of the lower electrode are exposed and seen through those cutouts to horizontally adjoin in the cutout of the upper electrode. The electrostatic speaker is driven via a clip having electrodes in response to audio signals, wherein drive voltages are applied to each of the upper/lower electrodes and the diaphragm.
