<p>A variable geometry transducer diaphragm (10) having an electrical conductor layer (26), with a conductor pattern, is positioned on an insulating layer (28). Magnets used to create an electromagnetic field around the conductors may be placed in the insulating layer (28) or formed as part of the frame (14) supporting the diaphragm (20). Alternatively, the frame (14) may be constructed to function as plates of a capacitor creating an electrostatic field around the diaphragm (10).</p> |
