Abstract:
1. An electrostatic loudspeaker assembly comprising: a) at least one stator panel in the form of a substantially rigid plate having an electrically conductive core and an insulating coating, and having its opposed major surfaces interrupted by a plurality of apertures covering a main area of the stator panel, wherein the stator panel is formed with: wherein the insulating coating of the stator panel completely covers all surfaces of the stator panel in the main area, including surfaces around the sides of the apertures; b) a flexible diaphragm generally co-extensive with the main area of the stator panel and situated in proximity to the main area of the stator panel, portions of the diaphragm being movable under the influence of electrostatic forces; and c) a spacer, formed of an insulating material, situated between the stator panel and the diaphragm which prevents contact between the diaphragm and the stator panel, the spacer comprising spacer apertures that define boundaries of the movable portions of the diaphragm; and the spacer having continuous or approximated curvature corresponding to that of the stator panel, with the proviso that:
