ABSTRACT:
An audio transducer having a cylindrical diaphragm molded with contoured ridges. The diaphragm includes at least two lobes, each extending from a central expanse to the transducer frame. The lobes may have different radii and different angular arc lengths. A driver attached at the central expanse may include a double-sided etched coil, or may be provided by an electrostatic driver having a charged filament attached to the diaphragm. The transducer diaphragm may include a central third lobe having different size and structural characteristics to provide added low frequency response. The transducer may be configured to provide omnipolar sound radiation with opposed spaced-apart semi-circular cylindrical diaphragms arranged to pulse symmetrically toward and away from each other.
