キン材２２ｂ。A damper 24 is provided at the center of the diaphragm 22, and a downwardly protruding portion 24a of the damper 24 has a magnetic circuit 1.
This edge 23. is adhesively bonded to the upper surface of the upper plate 19 of 6. The damper 24 is integral with the core material 22a of the diaphragm 22. That is, the diaphragm 22 is made of a core material 22 which is made by heat-molding a material whose edge cloth is impregnated with a thermosetting resin so as to have a large number of concentric corrugations.
A skin material 22b made of ring-shaped aluminum foil or the like is provided on the upper and lower surfaces of a.
