SPEAKER, AND MANUFACTURING METHOD AND MANUFACTURING DEVICE THEREFOR

摘要

A manufacturing device for a speaker is provided with a first to a third guide.  A frame is guided by the first guide and mounted on the manufacturing device.  A yoke is guided by the second guide, and the frame and the yoke are coupled.  A plate to which a magnet is joined is guided by the second guide, and the magnet and the yoke are coupled.  A voice coil is guided by the third guide and mounted on the manufacturing device.  The voice coil and a diaphragm are coupled.  The fame and the diaphragm are coupled.  The frame, the yoke, the plate, the magnet, the voice coil, and the diaphragm are then extracted from the manufacturing device.  By the above manufacturing method, the gap between the plate and the yoke of the speaker can be narrowed, the speaker can be manufactured with good yield, and the manufacturing cost can be reduced.
