ABSTRACT:
An electroacoustic transducer having a diaphragm apparatus. The diaphragm apparatus has an annular diaphragm and a pair of outer and inner edges respectively conjoining with the outside and the inside of the diaphragm. Both edges have sets of pleats arranged continuously along the circumferential directions of the diaphragm but directed in opposite directions to each other. Each pleat, at least in the outer edge, comprises a bottom line extending from a boundary between the outer fixing area and the outer edge to a boundary between the outer edge and the diaphragm wherein an arc defined by the point of intersection of the inner end of the bottom line of any pleat in the outer edge and the second boundary and the point of tangency on the second boundary of a line through the point of intersection of the outer end of the same bottom line and the first boundary subtends a central single .theta..sub.0 and the position of the former point of intersection is given by the relation; ##EQU1## where .theta..sub.0 is the central angle subtending the arc, and R, r, A and a are the radii of the first boundary, the second boundary, a third boundary between the diaphragm and the inner edge and a fourth boundary between the inner edge and an inner fixing area conjoining with the inner edge.
