Abstract
An electromechanical magnetic transducer with a moving armature that is adjustable relative to the working gap. The armature comprises an armature leg, crosspiece, and yoke arms, the adjustment being accomplished by inelastic distortion of the yoke arms. Substantially translational movement of the intrinsic position of the armature leg during adjustment is achieved by providing in each yoke arm one or more struts that undergo S-shaped distortion upon application of adjusting forces in appropriate directions. The structures are further adaptable for rotational adjustments of the armature leg in the gap.
