の振動板２２とすることもできる。 This edge 23 and damper 24 are connected to the diaphragm 22
It is integrated with the core material 22a. That is, the diaphragm 22 has a skin material 2 made of ring-shaped aluminum foil or the like on the upper and lower surfaces of a core material 22a which is made of wire cloth impregnated with a thermosetting resin and heat-molded to have a large number of concentric corrugations.
2b and 22c, and this core material 2
The peripheral portion of 2a is extended to form an edge 23, and the inner peripheral portion is extended to form a damper 24 having a downwardly protruding portion 24 at the center. In addition, Edge 2
3. The corrugations of the damper 24 and the core material 22a are formed to have different pitches and heights. Furthermore, the core material 22a to which the skin materials 22b and 22c are attached may be formed into a truncated cone shape to form the diaphragm 22 in the shape of a truncated cone.
