ABSTRACT:
A transducer device such as a loudspeaker or microphone has a U-shaped core of magnetically permeable material with attached pole pieces defining a gap and a stationary electrical coil around the core. A permanent magnet is positioned for movement through the central portion of the gap as directed by a variable magnetic field within the gap. The permanent magnet has diagonally positioned poles of like magnetic orientation to provide a north-south pole combination facing one of the pole pieces and a complementary south-north pole combination facing the other pole piece.
