Abstract: It is an object of the present invention to provide a loudspeaker structure suitable for use in almost full range in relation to a reproduction frequency band of a conventional ultrathin-type loudspeaker by resolving the defects of the loudspeaker and expanding the frequency band. A multipoint driving loudspeaker in which a single diaphragm is driven by a plurality of voice coils, having a plurality of holes 11a for connection with voice coils 12 at arbitrary positions on the diaphragm 11, an outer periphery of each voice coil or each voice coil bobbin 12a constituting the voice coil being joined to an inner periphery of each hole, each magnetic circuit for driving the voice coil being placed at an inner periphery of the voice coil or of the voice coil bobbin correspondingly to each voice coil, and the magnetic circuit including two magnets 82 with the same poles positioned at opposite side each other and being used as a repulsion magnetic circuit with a center plate 81 grasped between the magnets.
