ABSTRACT:
A taut armature resonant impulse transducer (100) includes an armature (12), an electromagnetic driver (24, 26) and a magnetic motional mass (18). The armature includes upper (14, 15) and lower (16, 17) cross-coupled non-linear resonant suspension members, each including first and second non-linear springs (62, 72) connected to a stepped central region and to opposite contiguous planar perimeter regions of an eIectromagnetic driver (24, 26) which effects an alternating electromagnetic field. A first end of the second non-linear spring is positioned within a periphery defining a shape of the first non-linear spring. The magnetic motional mass (18) is suspended between the upper (14, 15) and lower (16, 17) cross-coupled non-linear resonant suspension members, and provides an alternating movement in response to the alternating electromagnetic field which is transformed through the upper (14, 15) and lower (16, 17) cross-coupled non-linear resonant suspension members and the electromagnetic driver (24, 26) into motional energy.
