Abstract

PURPOSE:To ensure the positioning of each magnetic circuit, by independently locating the magnetic circuit every side and coupling the magnetic circuits with connector at the corner mechanically and magnetically. CONSTITUTION:The voice coil bobbin 11 fixed to the voice coil 12 is fixed to the diaphragm with the flange 11a. The magnetic circuit unit 2 consists of the plate 21, yoke 23 and magnet 22. Further, the corner section of the magnetic unit 2 is mechanically and magnetically coupled with the connector 3 made of magnetic metal material. The effective length of the voice coil is made longer with this coupling, the driving force is increased and the positioning of the magnetic circuit unit can be ensured.
