DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a watch structure
using a piezoelectric element in the H + sound generating portion at the time of an alarm.
Heretofore, as the sound generating part of the clock with an alarm, the one using 'ttim type or
piezoelectric type buzzer or the number 4 <x! ???????? Generally, in the case of the
piezoelectric type, the piezoelectric element is directed to a thin diaphragm, and the diaphragm is
vibrated to generate sound, which is released from the back discharge hole. It was fall. However,

hand, in order to improve the defects) front lid: ? directly IE electronic element F contact 11 L /
and vibrate the fire itself and generate a sound 01 has already been proposed. However, in this
case, it is necessary to increase the size of the pressure '17 -element in order to make it possible
to capture 11 points and 9 points as in the back story. It is. In order to become a single hard
dragon, this sticky east, 'heavy state and soil' liL element overlap in a plane, it becomes a
necessary '+ l +-pond pressure spring or a cover. The father secured the child's clearance fiil in
the battery holding spring and the river 'di, and as a result, 1v of the watch had ly (d1 lack). Also,
recently it is customary to use lithium 'heavy state, or so-called coin type heavy metal lJ pups or
large, heavy, it will necessarily become east IL + boron r surface aspectally, as a result If the
thickness of the battery holding spring is increased by increasing the thickness of the battery
holding spring, the battery holding spring may not hold the battery firmly. This thing Eri, "" fX + f

or l 'l <f (I had a drawback of This invention is the above-mentioned mark, co / IJ11. , A: It is to
provide a m-structure capable of making the thickness 61 thin in the groove 6- (with the table
itself fixed to the diaphragm itself by fixing the (-(2) 101; is there. Hereinafter, the present
invention will be described in detail based on the drawings, but parts not directly related to the
present invention will be omitted from the drawings on the assumption that known techniques
are used. FIG. 1 is a cross-sectional view of an embodiment of the present invention, FIG. 21A is a
plan view of a back cover on the piezoelectric element bonding side of FIG. 431 and a third side
(a plan view of another embodiment). In Figure 1 and Figure 2, 1 is a watch case, 2 is a
windshield, 3 is a waterproof pad, and 4 is a close-up plate. 5 is a tableware, and it is watch case
1 and an external cover-C some.
6 is a middle frame to hold the mono-ne, 7 waterproof. A piezoelectric element 8 is fixed to the
back iron 5 by contact 9j. A thin plate insulating member 9 made of a polymer material is fixed
to the piezoelectric element 8 in this embodiment. It is a support member that locates and
supports the 1L IL pond 10, which is a 101 'city pond. Reference numeral 12 is a battery
receiving spring, and electricity l'l'J $, l! Between the cathode of the battery 10 and the cathode
pattern disposed on the acetabic protuberance 13. 1 (3) 101, J It is a well-known member for
taking. Reference numeral 14 denotes a spring member disposed on a circuit base 13 in a buzzer,
driving output 4r- in a fixed manner, and a resilient member for achieving a top-down conduction
between the lamp and the primary electric element 8. Generally, A coil spring or the like is used.
The reference numeral 15 is a member 1: It +, a bullet 1J for electrically conducting the pond
10QN brownout and the back cover 5 to each other. At one end of the earth element 8 + @, the
back cover is closed and the ceramic case of the battery 10 is in contact with the side. On the
other hand, the battery 10 is pushed to the back -a1lIll by ? other love bar) not 12, and the
upper limit 17 ? ? t?L??I :, 4 [!! Add a cart on the edge "(T9 and put it on the king device 6,
but! If this wagon is within 6 guhum, the buzzer's volume of i'f will greatly affect the amount of
jcV / 1 $ or friends. The reference numeral 16 denotes each part necessary as an alarm clock (a
small part or a part being stored, or it is not related to the present invention), so the illustration
of 111 physical + i4 dragons is omitted. The fI line portion in FIG. 2 is for lowering the shape of
the thin plate-like e # i vinegar 11?. In this example of the insulating member 9 & 1 principal
axis r, t + F: calculator (= is concentric with Is, but not fixed in 'inside! J: Rice in pond 10 1: May
be rice. It is apparent that the father, e6, and the material 9 and the stiffness C may be reduced to
a value IIj so that the anode of the battery (4) 0510 and the piezoelectric element 8 do not
contact. FIG. 3 shows another embodiment in which the planar shape of the thin plate-like
insulating member of FIG. 2 is changed. As detailed above, the piezoelectric element is fixed to
the back cover! Alarm at the time of alarm having a structure of a sound generation unit
comprising In this case, an insulating member for electrical shorting is disposed between the
battery and the piezoelectric element, and the battery 1 is directly pressed against the insulating
member. Without, and to get out the watch thickness 7'D8, "I have been able to obtain a watch
stock having a great effect in practical use.
