ABSTRACT:
A planar film speaker(200) utilizes a first planar film diaphragm (102), and a second planar film diaphragm (104). A taut armature reciprocating impulse transducer (100) is positioned at an edge between the first planar film diaphragm (102) and the second planar film diaphragm (104). A first transmission medium (120) couples the taut armature reciprocating impulse transducer (100) to the first planar film diaphragm (102), and a second transmission medium (122) couples the taut armature reciprocating impulse transducer (100) to the second planar film diaphragm (104). An audio input signal is converted to tactile energy by the taut armature reciprocating impulse transducer (100), which is then converted by the first planar film diaphragm (102) and the second planer film diaphragm (104) into acoustic energy.
