Abstract
A taut armature reciprocating impulse transducer (100) which typically provides a non-linear hardening spring response is adapted to provide a non-linear softening spring response by the addition of magnetic damping elements (106). Two or more taut armature reciprocating impulse transducers (100) can be utilized to produce a mechanical acoustic crossover network (700) which operates to produce a wide frequency response when at least one of the two taut armature reciprocating impulse transducers (100) is adapted to provide a non-linear softening spring response. The mechanical acoustic crossover network (700) allows multiple taut armature reciprocating impulse transducers (100) to be operated together from a signal input. When the mechanical acoustic crossover network (700) is enclosed in a housing (812), the mechanical acoustic crossover network (700) can be operated as a headphone to deliver an audio output.
