发明名称 PIEZOELECTRIC SOUNDING BODY
摘要 PURPOSE:To obtain a stable tone by providing a semicirculararc elastic part to a piece from a terminal connected to a piezoelectric buzzer element so a to absorb the force transmitted between the terminals lengthwise. CONSTITUTION:The terminal 7 has a cut-piece 8 and an elastic part 9 formed as a semicircular-arc to absorb an external force from the terminal 7 is provided to the cut-piece 8. The tip of the piece 8 is fixed to a thin piezoelectric ceramic plate 2 and a thin metallic plate 3 by solder or the like. Thus, in mounting the piezoelectric sounding body onto a print wiring board a little floating state by only providing the circular-arc elastic part to the piece formed incorporatedly with the terminal, a force is exerted to the case 4, then the force is absorbed by the elastic part 9 even if the force is exerted to the terminal 7 in the lengthwise direction. Thus, no force is exerted to the piezoelectric buzzer element and no tone is changed.
