A frame 14 supporting a diaphragm 12 by its outer periphery is constructed by a connecting ring 30-which is formed in an annulus following the shape of the outer periphery of diaphragm 12-to base 28 which comprises a bottomed cylinder portion 28A and a mounting portion 28B which extends radially outward from the bottomed cylinder portion 28A which is a part of the magnetic circuit unit 18. The connection is achieved by the caulking of the ring 30 and the mounting portion 28B with the diaphragm 12 clamped therebetween.
