An taut armature, resonant impulse transducer (100) includes an armature (12), including an upper (14) and a lower (16) non-linear resonant suspension member, each including at least two juxtaposed planar compound beams (202, 204 and 206, 208) connected symmetrically about a contiguous planar central region (210), and further connected to two contiguous planar perimeter regions (212, 214), an electromagnetic driver (24, 26), coupled to the upper and lower non-linear resonant suspension members (14, 16) about the two contiguous planar perimeter regions (212, 214), the electromagnetic driver (24, 26) effecting an alternating electromagnetic field in response to an input signal, and a magnetic motional mass (18) suspended between the upper and lower non-linear resonant suspension members(14, 16) about the contiguous planar central region (210), and coupled to the alternating electromagnetic field for generating an alternating movement of the magnetic motional mass (18) in response thereto, the alternating movement of the magnetic motional mass (18) being transformed through the upper and lower non-linear resonant suspension members (14, 16) and the electromagnetic driver (24, 26) into motional energy.
