circuit portion formed on the other side of the plate 1, which is specifically cut away in "," 1; for
example, a predetermined -resistance is formed on the substrate 1, capacitor chip, The transistor

piezoelectric unit to be described later is formed on the lIC substrate movement unit 4. The
pattern W1 sand 7 is electrically connected to the predetermined conductive pattern of the
connection pattern SCZ or the circuit portion 5 through the connecting portion 2. From the other
predetermined conductive pattern of the circuit portion 5 which has been worn, another
connection pattern 9 is formed extending to the unit (3) end near the vibrating portion 4.
Connection pattern 8.9 and 1 [on pole 7 preferably simultaneously formed at the time of

surface on which the W pole 10m is provided is opposite to that of the substrate l. Λ 111 . The
adhesive 11 is attached on the electrode 7 of the vibrating portion 4 so as to be =. [@ 10a of the
piezoelectric unit lO and the connection pattern 9 are pneumatically connected to each other by
the lead wire 12 soldered to one end. The radial vibration or surface S [vibration of the unit 10
occurs as a result of vibrational signal storage λ from the circuit unit 5 to the piezoelectric unit

order to add such a piezoelectric buzzer to a mounting body (not shown) when a composite
sounding body consisting of 4 performs a bending vibration 1) and an audible sound is generated
in front of the sounding body Base part not covered with resin cover 4I6 (4) Plate part Fix by
fixing by pipe screw etc., or engage with other part Fc @ grease part provided on the mounting
body and screw it in other part You may do so. According to this embodiment, since the sound
producing unit and the circuit unit can be integrally formed on a single IC substrate and the
circuit unit can be made of a plurality of resin units, the structure is simple and small, and
particularly the circuit unit. The package is extremely simple, and the electrical connection
between the speaker unit and the circuit unit is made by connecting 10,000 units of the sound
generator unit -108 and the connection pattern 9 extended to the vicinity of the sound generator
unit with the connection pattern 9 Since the conductive pattern is used, bonding (solder)
locations are reduced, the number of assembly steps is reduced, and the good product rate is the
same, and the conductive pattern 7.8.9 can be temporarily formed with the pattern of the circuit
portion 5 and thus excess. Furthermore, in the above embodiment, since an alumina ceramic

plate is used as the IC substrate, one internal internal loss in the vibrating portion is obtained
compared to the one using a gold-plate or a resin plate. Small Δ, efficient sound Since the 0
connection pattern 9 which can be generated is extended to the vibrating portion 4Fc through
the connecting portion 2 (5), the connection wire 12 may be a short lead 12 of the connection
position of the pattern 9 and '14110a, Processing becomes very easy FC.
In the above embodiment, the entire other side of the substrate 1 is made of Yr resin, but
according to the present invention, as shown in FIG. In the case of OC where resin wave -a 139r
may be applied leaving only the circuit part 5 as shown (3), the mounting holes 14 of the
substrate 1 at both ends 1a and 1b of the substrate 1 as shown. It is good for n. Further, as
shown in FIG. 3, the triangular resin wave alG may be applied to one corner of the substrate 1 so
as to be disposed at one corner of the circuit unit 5 at 1 and this circuit unit 5rl). In this case, VC
can be formed by the resin dry 16 resin dip method in the same manner as il'll IH1 shown in FIG.
In addition, the blind holes 17.18 may be provided diagonally, and six of them may be provided.
However, for the simplification of t light, only the resin covered portion t is schematically shown.
Fig. 11 shows only another 10,000 i + of the substrate in the other embodiment. This
embodiment uses the node line (6) supporting type sounding body, and the circuit portion and
the resin-covered partial light above each embodiment. Is the same as See the same, alumina! A
part of the IC substrate 19 consisting of # 斡 is surrounded by one ring (7) 2117) ′ '21 with five

vibrating portion 22 in the same manner as in the embodiment shown in the first example, and
electrical signals are held on this unit, whereby the unit is projected in a convex direction or area,
and as a result, the unit and vibration The complex sounding body consisting of the part 22
bends and vibrates according to the original node line of the shooting part 22, and an audible
sound is generated in front of the sounding body J [: each protrusion 71Ii, the base '#] 11.19 An
ICC substrate of aluminum (7) ceramic plate is shown as an example, but the present invention is
not limited to this, and it is possible to use a semiconductor substrate such as silicon, etc. In this
case, it is a slit etching process It can also be formed. Also, use a resin board sound such as a
printed wiring board as the substrate 1.19 to process% l. In addition, although the sound
generator is configured in a two-terminal type in the above embodiment, the present invention is
not limited to this and may be configured in a three-terminal type by adding a feedback charge

W1 pole is divided in part to provide a feedback W1 pole, and the feedback W &' -It may be
connected with the tread portion. In this case, although three lead wires and their corresponding
soldering are required in the past, one lead wire processing is required, and assembly becomes
very ic. Furthermore, the vibration part processing pressure (If the unit is formed into an
arbitrary shape, the processing is as described above.) As described above, the sound generating
part r # is formed on the circuit board, and the circuit part on the board is resin Since it is
covered, it is possible to reduce the size and make it possible to reduce the amount of dust, (8)
the package of the circuit section can be very easily dormitory, and the number of wiring
processing places such as soldering is reduced and the number of assembling steps is reduced.
Have a huge effect on practical use, such as the failure of
