[Detailed Description of the Invention] This device is a pressure i! A forceps buzzer FCAtb that
emits a sound by causing a single action on a diaphragm using an element. Conventionally,
piezoelectric-child t! @ The ladder buzzer has a tz7 structure as follows: 1. For example, a flat
electrode substrate tube is fixed to one side of a flat pressure N element, and another side is
provided with a h opening and 1 lit from other side Form a peristaltic plate. The diaphragm is
held on the support table via its outer peripheral edge t spacer etc., and an alternating force mEEt
# j is added to two screws provided on the pressure ≦ element to cause distortion in the
piezoelectric element, Pregnancy, 1 plate t-overdrive to generate a front tube-However, in the
conventional i-puppu structure, it is sufficient that ice blisters are produced in the central part of
the -fai plate.振 ll1lt gain k requires a large driving position, for example, one child storm watch
etc. and ^ 6 small pivoting position is not enough to obtain mu, and bottom out-iA winter is bad
The ice width is small because the spring constant in the plate-like vibration j plate line vibration
t ζ has a large defect 1 and the + I M-type has a defect that the problem is negative ・ This
defect f knee (2) 0-2 L, but it is fixed to the electrode substrate and% At this moment, it will affect
the strength of the plate itself which causes the vibration of the piezoelectric element. Therefore,
the disadvantage of this invention is: 4% noise with excellent sound 4 conversion efficiency. In
order to provide the purpose, however, this consideration is that the center of the am plate
formed by solidifying the pressure 4A core 1 is supported at one point on the support base, and
the% of the jiil + plate is 1%. It is an electronic pin made by dividing a "C-K" J plate into a radial
slit provided in the center or up to the b-shoulder.絖 明 ・ 1st @ @ 工, symbol α) is a swing plate

is, for example, a thin film electrode deposited with silver) 6), a lead which is extended from the
illustrated i power source. (4) The diaphragm 0) connected to one end of the sword and
configured as above is provided with four slits (2) radially from the central middle portion of the

'D 2, the diaphragm α) is divided into a plurality of layers of the same layer shape. There is a

piezoelectric element @ as a through hole “C” pole lead hole • In addition, it is also possible to
immerse the glaze agent J into the moving plate a). Figure 2 shows that the resonance plate [2
