Abstract

PURPOSE:To simplify the assembling process, by applying a sound signal to a piezoelectric vibration diaphragm via a conductive flexible soft substance layer connecting a piezoelectric vibration diaphragm on a bottom frame. CONSTITUTION:At the side surface of a frame made of metal 9 with bottom, and the side surface is provided with a terminal 7 isolated with the frame 9 and another terminal 7' directly coupled with the frame 9. The terminal 7 is connected to a film electrode on a piezoelectric material plate 3 of a piezoelectric vibration diaphragm 1 via a calking piece 12 and a lead 11. Further, the other terminal 7' is connected with a brass thin plate 2 of the piezoelectric vibration diaphragm 1 via the frame 9 with bottom made of metal and a conductive flexible substance layer 10.
