Abstract: The present invention provides an electromagnetic signal converter for an osteophone, comprising a soft magnetic yoke, an electrical coil arranged concentrically to the longitudinal axis of the yoke, an elastically suspended, soft-magnetic armature which, viewed in the direction of the longitudinal axis of the yoke, is separated from the yoke by a working air gap and can move along the longitudinal axis of the yoke, and a permanent magnet which is magnetized in the direction of the longitudinal axis of the yoke in order to generate a magnetic biasing voltage of the yoke and of the armature, characterized in that the permanent magnet and the coil do not overlap one another in the direction of the longitudinal axis of the yoke and that means is provided for dividing the magnetic flux that can be produced by the coil onto at least two flux paths, wherein one flux path runs outside of the permanent magnet, and characterized in that the permanent magnet, yoke and coil are surrounded in the signal converter of the

Abstract: The invention relates to an electromagnetic signal converter for an osteophone, comprising a soft magnetic yoke (1), an electrical coil (2) arranged concentrically to the longitudinal axis of the yoke (1), an elastically suspended, soft-magnetic armature (4) which, viewed in the direction of the longitudinal axis (5) of the yoke (1), is separated from the yoke (1) by a working air gap (8) and can move along the longitudinal axis (5) of the yoke (1), and a permanent magnet (9) which is magnetized in the direction of the longitudinal axis (5) of the yoke (1) in order to generate a magnetic biasing voltage of the yoke (1) and of the armature (4).

Abstract: Cup-shaped magnet for electric motors having two face surfaces, two lateral surface, and two top surfaces, which are curving between the face surfaces along the lateral surfaces, whereby the lateral faces are chamfered in a v-shape.
