Title: Speaker
Inventor: SUGIYAMA SHIGERU
IPC: H04R9/06
Filed: 2000-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic speaker that can surely prevent a diaphragm from coming off from a frame, can promote automation of its manufacturing process and can simplify the manufacturing process. SOLUTION: The frame 14 supporting an outer circumferential part of the diaphragm 12 is configured such that a ring 30 formed to be a torus along the outer circumferential shape of the diaphragm 12 and a base 28 consisting of a bottomed cylinder section 28A of a magnetic circuit unit 18 and of a mounting section 28B extended radially outward from the cylinder section 28A are coupled with each other. This coupling is made by caulking the ring 30 and the mounting section 28B with the diaphragm 12 inserted inbetween. Thus, the support strength of the diaphragm 12 by the frame 14 can considerably be improved in comparison with the adhesion of diaphragm singly to the frame in a conventional speaker. Moreover, the need for coating of an adhesive is eliminated to easily automate the speaker manufacturing process.  Furthermore, the viscosity adjustment of the adhesive and the dry process after the coating of the adhesive are not required to simplify the manufacturing process.
