Abstract

PURPOSE: To make easy the automation of assembling work, by constituting the back plate of a condensor microphone with a curved revolutional surface which is not flat and has no hole on the effective surface.
CONSTITUTION: Three holding nails 11 formed with right triangle notches 11a horizontal at the lower surface are provided at the tip inside of an insulation holder 10, and the nails 11 are inserted to the notches 11a for the circumferential plane 9 of a back plate 4 while slightly pushing open with a tool, and the lower part than an effective surface 7 is clipped with the nails 11 and the assembly is pressed in an intermediate cylinder 12. A flat plane 13 is mounted onto a size-setting tool for a gap 3, and the holder 10 is pressed in the cylinder 12 until the gap between the tool and the effective surface 7 reaches a prescribed size, and the both are fixed by suitably applying an instantaneous adhesive of cyanoacrylate from the lower side to the contact surface between the holder 10 and the sylinder 12.
