ABSTRACT:
An improved transducer which includes a rigid frame and a permanent ring magnet mounted to the frame. A small bobbin, preferably formed of aluminum foil, is sized and arranged to fit within the open end of the magnetic gap while permitting motion of the bobbin therein. A voice coil is wound on the bobbin and connectable to receive an audio signal, similar to a conventional voice coil driver system. A pair of flexible, curved diaphragms are disposed in the frame, generally free to move except for a distal end of each diaphragm which is fixed to the frame. The diaphragms can be of generally cylindrical or partial-cylindrical shape.
