DESCRIPTION JPS63215299
[0001]
Industrial Applicability The present invention has a configuration in which a piezoelectric
vibrator in which a ceramic piezoelectric body is bonded to a metal plate is housed and fixed in a
case, and is used for generating sound such as operation sound confirmation sound of various
alarms and push button switches. It relates to a piezoelectric speaker. Prior Art Conventionally,
this type of piezoelectric speaker has a configuration as shown in FIG. In FIG. 12, 1 is a ceramic
piezoelectric body, 2 is a metal plate, and both are bonded to become a piezoelectric vibrator 3. 4
is a case and has a sound emission hole 5. 6 &, at) are input terminals, which are fixed to the case
4 and electrically connected to the electrodes of the ceramic piezoelectric body 1 and the metal
plate 2, respectively. Problems to be Solved by the Invention The piezoelectric sounding body is
directly attached to a printed circuit board or directly attached to, for example, a case of an
alarm, but in this case, most of them are manual methods. On the other hand, in order to cope
with the recent cost reduction, a method of attaching a piezoelectric sound generator to an
automatic insertion device has been adopted. However, in the conventional configuration, in the
case of automatic insertion, there is a problem that the place where the machine grabs the sound
generator is not determined, and the automatic insertion device can not be used. The present
invention solves such problems, and an object of the present invention is to provide a shape that
enables automatic insertion of a piezoelectric sounding body. Means for Solving Problems In
order to solve this problem, in the present invention, a case in which a piezoelectric vibrator is
accommodated and fixed and an input terminal is fixed, a recess or a protrusion or a part of the
case is used. By providing the hole, it can be used for the automatic insertion device. With this
configuration, the piezoelectric sounding body can be accurately held by fitting the component
holding portion of the automatic insertion device with the concave portion, protrusion or most
portion of the case of the piezoelectric sounding body, and to the predetermined hole of the
printed circuit board It can be inserted correctly. When the printed circuit board is inserted into

the hole, the insertion force can be reliably transmitted. EXAMPLES Examples of the present
invention will be described with reference to the drawings. The same parts will be described with
the same reference numerals. The piezoelectric vibrator 3 has a ceramic piezoelectric body 1 and
a metal plate 2 bonded to each other, and is fixed to a case 4. The case 4 has a sound release hole
5, and the input terminals 61L and 6b are fixed. Each configuration described above is the same
as that of the conventional example. The feature of the present invention is the recesses 71L, 7b
provided on the side surface of the case 4. In FIG. 1a, the semi-cylindrical concave portions 7N
and 7b are provided, but the component holding portion of the automatic insertion device can be
held in a cylindrical shape. Hold the side of the sounding body and insert it into the
predetermined hole position of the printed circuit board.
FIG. 2 shows another embodiment of the present invention in which the concave portions 8 &,
8k) on the side of the sound generator are formed into a prismatic shape, and the component
holding portion of the automatic insertion device is fitted with the prismatic shape. Allow to grab
and insert into printed circuit board. At the time of insertion, since it is a prism, it is structured to
receive the insertion force of the insertion device by the surface, so that the force to be pressed
into the printed circuit board can be transmitted reliably. 3 and 4 show the depressions 7 & in
FIG. 1 and FIG. To, convex with respect to 8a, 8b) i9z, 9b. In this case, the component holding
portion of the automatic insertion device is concave and engages with the protrusion of the
sounding body. Good transmission of insertion force. FIG. 5 shows another embodiment of the
present invention, in which the shape of the recesses 11a and 11b provided on the side surface is
incomplete and leaves a part. This helps to prevent the automatic insertion device from
accidentally grabbing the part. In Fig. 6, Fig. 7 and Fig. 8 small concaves 13, 14 ? 15 & 15k) are
provided in the semi-cylindrical concaves 12a, 12b on the side of the case 4 and the automatic
insertion device grabs the sounding body At this time, it is possible to prevent the malfunction by
fitting with the convex portion provided in the component holding portion, and to increase the
insertion force to the printed circuit board. 9, 10 and 11 show another embodiment of the
present invention, in which the side faces of the case are notched (16i1L, 16t)), in the side faces
of the case, square holes 172L, 17t), round holes 182L, 181. ) Is provided. As described above,
according to the present embodiment, it comprises the piezoelectric vibrator, the case, and the
input terminal, and can be used for an automatic insertion device by providing four parts,
projections or holes in a part of the case. The press-in can be accurately performed at a
predetermined position. In the embodiment, the sound generator is described as a two-terminal
type other excitation type in which the periphery is supported and fixed, but the same applies to
a three-terminal type self-excitation type of node support. Further, it is apparent that the shapes
of the concave portion, the convex portion and the hole described in the present invention
include, in addition, a triangular prism, a triangle, a triangular weight, a single square ball and the
like. As described above, according to the present invention, a piezoelectric vibrator having a
ceramic piezoelectric body attached to a metal plate, a case for housing the piezoelectric vibrator,
and an input terminal, and a concave portion in a part of the case, Alternatively, by providing
04-05-2019
2
projections or holes, the automatic insertion device can be used to accurately insert the printed
circuit board in a predetermined position. In addition, the sounding body provided with a
prismatic concave portion, convex portion or hole, and the sounding body provided with a hole in
the concave portion hold the sounding body correctly by fitting with the sounding body holding
portion of the automatic insertion device. It can be accurately inserted into a predetermined
position of the substrate.
Recesses, bumps when inserting. By using the holes, the insertion pressure can be accurately
transmitted to the case, and incorrect insertion and removal can be prevented.
