DESCRIPTION JPH01227599
[0001]
FIELD OF THE INVENTION The present invention relates to a method of manufacturing a
piezoelectric buzzer used in electronic equipment and a piezoelectric electroacoustic transducer
used in a piezoelectric handset of a telephone. 2. Prior Art Conventionally, a method of
manufacturing this type of piezoelectric type electroacoustic transducer has been as shown in
FIG. In FIG. 2, the lead wire 3 is soldered to the piezoelectric vibrator 2 as shown in FIG. 2a to
make it as shown in FIG. 2, and the leakage hole of the back case 6 as shown in FIG. The acoustic
resistance material 4 is adhered to 5a to form FIG. 2d, and this is assembled and sealed with the
front case 1 as shown in FIG. 2e. Problems to be Solved by the Invention In such a conventional
manufacturing method, when changing the length and material of the lead wire 3 depending on
the purpose of use, or changing the material of the acoustic resistance material 4 to change the
acoustic characteristics, In order to change from the process of (1), the time loss for switching
the process and the material loss are not negligible in the present day when the production of
many kinds and small quantities is the center. The present invention solves such problems, and
provides a method of manufacturing a piezoelectric electroacoustic transducer that can be
produced without problems even in high-mix low-volume production. Means for Solving the
Problem In order to solve the problem, in the present invention, a front case, a piezoelectric
vibrator, and a rear case are assembled first. In this method, a lead wire is inserted from the small
hole provided in the rear and back case, and the leakage hole is covered with an acoustic
resistance material. Operation In this method, the basic part can be mass-produced because the
mechanism for generating the basic function sound is first constructed. It is a post-process to
change the length and material of the lead wire and the acoustic resistance material depending
on the purpose of use, and it is possible to save the time loss for the type switching and the
integrity of the material. Embodiment FIG. 1 is a flow chart showing a method of manufacturing a
piezoelectric electroacoustic transducer according to an embodiment of the present invention.

Front case 11 having a sound emitting hole 111L as shown in FIG. 1 a, piezoelectric vibrator 12.
The rear case 13 is assembled as shown in FIG. Thereafter, as shown in FIG. 1C, lead wires 14 of
material and length according to the purpose of use are inserted from the small holes 131L of
the back case 13, soldered to the piezoelectric vibrator 12, and adhesive 16 or the like is used.
The small hole 13a is closed. Then, the acoustic resistance material 15 is appropriately selected
in the leakage hole 17 of the rear case 13 and adhered as shown in FIG. 1C. This completes the
piezoelectric electroacoustic transducer. Effect of the Invention As described above, according to
the present invention, a front case constituting the basic function of the electroacoustic
transducer, and a piezoelectric vibrator.
Production leads by adopting a manufacturing method in which the back case is first produced in
a mass production system, and parts with different specifications depending on the purpose of
use, such as soldering of lead wires and adhesion of acoustic resistance material, are assembled
separately in later steps. The effects of shortening of time, reduction of material loss, cost
reduction by mass production of basic functional parts and the like can be obtained.
