Abstract
An electromechanical magnetic transducer with a moving armature having (1) substantially pure translational adjustability, or (2) adjustability characterized by a substantially definite pre-chosen ratio of rotation to translation. The armature comprises an armature leg and an armature support yoke having plastically deformable yoke arms. A yoke arm comprises a pair of struts that are mutually inclined to provide a toggle-like action upon application of an adjusting force, such action opposing or enhancing the tendency of the support of the armature leg to rotate.
