<p>An improved audio transducer (10) includes a diaphragm (22) having a pair of cylindrically-shaped webs (24, 26) that provide greater bandwidth, reduced distortion and greater horizontal dispersion of sound. The audio output of the transducer (10) is further improved by forming the diaphragm (22) of a polyvinyl fluoride film. Other improvements include the use of damping pads (66, 68, 70, 71) to damp internal sound waves and damping strips (73) on the diaphragm (22) to minimize distortion at the resonant frequency of the transducer (10).</p> |
