Abstract:
1. An electrostatic transducer comprising: a first impermeable electrode; a second impermeable electrode spaced from the first impermeable electrode at a distance which defines a region between the first impermeable electrode and the second impermeable electrode; a diaphragm disposed in the region and having a conductive layer for being responsive to electrostatic forces to produce acoustic output, the diaphragm including (1) a first end spaced closer to the first impermeable electrode than to the second impermeable electrode, (2) a second end spaced closer to the second impermeable electrode than to the first impermeable electrode, and (3) a curved center portion that connects the first end and the second end; at least one electrical contact respectively coupled to at least one of the first impermeable electrode, the second impermeable electrode, and the diaphragm, for coupling to an audio signal source; and at least one additional electrical contact respectively coupled to at least one of the first impermeable electrode, the second impermeable electrode, and the diaphragm, for coupling to a voltage source.
