摘要:PURPOSE:To attain thin profile by adopting a structure such that 3 foamed resin plates or over obtained the extruder forming method are laminated and adhered for a diaphragm. CONSTITUTION:Four foamed resin plates 31-34 are formed by the extruder forming method. Then throughholes 32a, 33a with a slightly larger size than a piezoelectric driver 21 are formed in the middle of the foamed resin plates 32, 33 located at the inside among the foamed resin plates 31-34. Then the four foamed resin plates 31-34 are laminated and adhered, then the piezoelectric driver 21 is contained in the throughholes 32a, 33a and contained in a piezoelectric driver contained space with piezoelectric driver support members 35, 36. Then a projection 22a of the foamed resin plate 32 is inrted to a frame 24 and an elastic support piece 23 is inrted between the frame 24 and the projection. Thus, the thickness of the foamed resin plates 31-34 is made very thin to attain thin profile.
