[Detailed description of the invention] Unplanned-to detect the power of the fan 1J and the

?. In 81311, 10.11 is a divided body of the case # 7, and by connecting this divided body 10.11,
the case 12 is constructed. The lower surface of the metal plate 13 is attached to the inner open
surface of the case 12 by 11i. 14 is a piezoelectric ceramic plate provided with electrodes in both
images), and this pressure electromagnetic wave @@ a (+ one electrode surface is adhered to the
upper side of the metal plate 13). 16 # i Oka axis cable line is this, 8 ? 16 of O gang axis cable

cable @ 160 core @ 16 is the piezoelectric am board 14 Connect to the electrode of the upper
port @tL, 1713 ? t-1 The lead 1117 for 9160 amps is welded to the metal plate 13 described
above. It is filled in the case 12 of 18 L above, and is a 1 m collection material of vibration of 9
silicone rubbers. In the case where the vibration detector of the above structure is attached to a
vibrating body such as a machine or an electric device, the strain of the vibrating body is
transmitted to the piezoelectric ceramic plate 14 and a flexural vibration is given to the
piezoelectric ceramic plate 14 A voltage is generated between the electricity of the piezoelectric
ceramic plate 14.
The merits of the present invention are as shown at 4 @@ l, depending on the thickness of the
portion to which the piezoelectric ceramic plate 14 is attached, ie, the thickness of the case 120

No. 611! Reference numeral l denotes another embodiment of the present invention, and in the
present embodiment, the piezoelectric piezoelectric aS plate 14 is directly inside the case 12 as
seen by the user i. In this case, the bottom plate t) * @ d of the four cases 12 is larger than the
length d2 of the upper WIIIL, which is O. In any of the above-described embodiments, the metal
mesh is attached to the inner case of the case 12C1 to shield it. In addition, although the case 12
is filled in the case 12, it is not limited to silicone rubber, and may be a vibration absorbing
material of neoprene rubber or epoxy resin. As is apparent from the above example, the present
invention is characterized in that dl> d2 but O and h, such as Kd,> d2 and in this case the
vibration transmitted from the outside is ?It works effectively to bend the 0-second surface.
Note that d2> d, which is transmitted to the 0-field building), f ? ? is transferred to the
piezoelectric ceramic plate so that the power transmitted to the piezoelectric ceramic plate is
reduced. is there. As described above, according to the present invention, since the external klK is
effectively transmitted to the piezoelectric ceramic plate, it has an advantage that the output
voltage is high and the sensitivity is high. In the case where a vibration absorbing material such
as silicone rubber is pivoted in the case, the resonance of the vibration detector is suppressed
and flat wave frequency characteristics are obtained, and in particular, the instrument according
to the present invention is an instrument. When used as an application, it has the advantage that
howling due to resonance can be avoided. 4, the simple 1 ? 1 Figure 1 is a perspective view of
