Title:
METHOD FOR MANUFACTURING SPEAKER
Document Type and Number:
WIPO Patent Application WO/2002/041667
Kind Code:
A1
Abstract:
A method for manufacturing a speaker comprising a step for forming diaphragm parts and positioning parts continuously on a stripe resin film, a step for arranging a frame or a protector on an upper or lower die and aligning the positioning part formed on the film with other positioning part corresponding to the positioning part formed on the film provided in the frame, protector or upper or lower die, a step for bonding the resin film formed on the diaphragm to the frame, and a step for cutting the diaphragm from the resin film. A position for bonding the diaphragm to the frame or protector can be determined easily by aligning the positioning part formed on the stripe resin film with other positioning part provided in the frame, protector or upper or lower die for arranging them. Furthermore, the number of parts can be decreased by eliminating a conventionally inevitable ring.
