SPEAKER AND METHOD OF MANUFACTURING THE SAME

Document Type and Number:

WIPO Patent Application WO/2005/086529

Kind Code:

A1

Abstract:

A speaker, wherein a cylindrical suspension holder (9) formed to be diverged downward is installed on the rear surface of a diaphragm (7) integrally with each other, and the peripheral edge of the suspension holder (9) is joined to a frame (5) through a second edge (10). Since an operation for adhering the suspension holder to the diaphragm and an operation for heating and drying an adhesive agent can be eliminated by this structure, productivity can be remarkably increased, and production facilities and space can be reduced.
