Abstract

PURPOSE:To simplify the structure of a driving part, by facing the same magnetic poles of two or more magnets to one another to form a magnetic circuit. CONSTITUTION:Two magnets 14 and 14' are magnetized in the direction of thickness, and the same magnetic poles face to each other. A movable coil 13 wound around a bobbine 12 is provided near a junction face 15 of magnets between centers 14-1 and 14'-1 of thickness of magnets 14 and 14'. By this constitution, a DC magnetic flux is applied perpendicularly to the movable coil 13 to constitute a driving part of the dynamic transducer for driving a vibration diaphragm 11.
