Abstract: A taut armature reciprocating impulse transducer (100) includes an electromagnetic driver (24, 26) which effects an alternating electromagnetic field in response to an input signal; an armature (12), including an upper planar suspension member (14) having a radial axis (50) therethrough and a lower planar suspension member (16) having a radial axis (52) therethrough coupled to the electromagnetic driver (24, 26), the radial axis (50) is oriented substantially perpendicular to the radial axis (52); and a magnetic motional mass (18) which is suspended between the upper and lower planar suspension members (14, 16), and which is coupled to the alternating electromagnetic field for alternately moving the magnetic motional mass (18) in response thereto. Movement of the magnetic motional mass (18) is transformed through the upper and lower planar suspension members (14, 16) and the electromagnetic driver (24, 26) into motional energy.
