  • Transducer with improved armature and yoke construction
    Patent number: 3935398
    Abstract: An electroacoustical transducer of the magnetic armature type having an efficient electromagnetic configuration with the armature being formed integrally with a support yoke. The yoke includes a base from which two arms extend generally parallel to the armature, the two arms engage pole pieces formed of laminations, and the vibrating end of the armature is positioned in the plane of the diaphragm and is connected thereto. The armature may include a boss or gusset adjacent to the contilever end of the armature to stiffen it and thereby raise the resonant frequency of the transducer. A casing is included which is spaced from the yoke and serves as a magnetic shield.
