Zusammenfassung:Acoustic transducers may, in certain aspects, include a curved diaphragm and an actuator coupled to the curved diaphragm to cause movement of the curved diaphragm. In certain embodiments, the curved diaphragm has at least one free edge. The left and right edges of the curved diaphragm may be associated with auxiliary supports. The acoustic transducer can be a multi-pole loudspeaker wherein a curved diaphragm radiates the sound energy in a modified dipole pattern. The curvature of the radiating surface of the transducer reduces sound cancellation from sound energy reflected by nearby surfaces.
