SPEAKER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To enable a magnetic circuit unit to be designed independently of the shape of a diaphragm so as to improve the design of a speaker in degree of freedom. SOLUTION: The speaker is equipped with a diaphragm 2 into which a dome 2a and an edge 2b are integrally formed; a joint supporting member 5 which is connected to a boundary 2c between the dome 2a and the edge 2b of the diaphragm 2, and extended inward or outward from the boundary 2c in the radial direction of the diaphragm 2; a voice coil 4 which is fixed to the extension end of the joint supporting member 5; and a magnetic circuit 3 equipped with a magnetic gap 3g where the voice coil 4 is contained.
