ABSTRACT:
A whole-surface driven speaker includes first and second support plates having sound-passing perforations and groups of magnets mounted on the plates. The plates are substantially parallel to each other. A diaphragm is disposed in between the plates. A plurality of conductor strips are mounted on the surface of the diaphragm. The strips are connected to receive pulse-code modulated signals. The strips respectively correspond to a plurality of binary bits of the signals of different bit significance. Each strip has a predetermined width and a predetermined number of windings and carries a predetermined current magnitude such that electromechanical forces on the diaphragm caused by the bit signals flowing through the strips are proportional to the respective bit significance of the strips.
