3.16 No. in the central office No. 6 Description of the invention
Method of manufacturing complex type transducer
8. Detailed Description of the Invention The present invention easily holds the position of each
transducer in the manufacture of a composite transducer in which a large number of cylindrical
transducers having electrodes on both sides are arranged in a set position and arranged. The
present invention relates to a method of manufacturing a composite transducer that facilitates
connection to the electrodes. FIG. 1 is a view showing the structure of a conventional complex
type transducer, where (A) is a perspective view of a transducer unit, and 伽) is a plan view of a
transducer incorporating the transducer unit, (C ) Is a side sectional view thereof. The side
surface sound insulator 2 is wound around the side of the vibrator 1 in advance, and the lead
wire 3 is soldered to the electrode of the vibrator 1 to form a vibrator unit. □ A plurality of
transducer units made in this way are arranged, and the bottom electrode bonded to the rear
surface sound insulator 4 is adhered to the upper surface of the frame 5. The lead wires 3 from
the respective electrodes of the vibrator are connected to the core wire 2 of the cable 6 and
taken out to the outside. The above structure is integrally molded with polyurethane rubber 8.
When such a structure is conventionally manufactured, (1) the vibrator requires a process of
individually winding side sound insulation bodies. (2) Positioning of the transducer unit requires
a positioning mark or jig. (8) The length of the lead wire 3 from the vibrator 1 to the core wire 7
is long and short. And the like, and there is a problem that the number of assembling steps is
increased, or the positioning of the transducer unit is difficult. The present invention has been
made in view of these problems. EndPage: Inserting a vibrator into a side sound insulator

provided with a hole for determining the mutual position of the vibrator and etching copper plate
for electrical connection to the electrode of the vibrator The invention is characterized in that the
contact piece is soldered and the etching copper plate is bonded to the side sound insulator and
integrally molded. The purpose is to simplify the manufacturing process and reduce the cost by
reducing the number of steps.
Method of manufacturing complex type transducer
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG.
2 is an exploded perspective view showing the steps of an example of the manufacturing method
of the present invention. In the figure, 4 is a rear surface sound insulator, 5 is a frame, 9 is an
etching copper plate, 10 is a side surface sound insulator, and holes 10h for inserting and
positioning the vibrator 1 are provided. An etching copper plate 11 is a thin copper plate similar
to the etching copper plate 9 (D contact pieces 9a and JJa are provided by etching. Next, in order
to assemble this, the side sound insulator 10 made of, for example, soft urethane foam is placed
on a work bench, and the vibrator 1 is inserted into the hole 1θa formed in the side sound
insulator 10 Strictly determine the position of. The etching copper plate 9 is placed thereon, the
contact piece 9 a is soldered to the electrode 1 a of the vibrator 1, and the etching steel plate 9 is
bonded to the side sound insulator 10. The rear surface sound insulator 4 is adhered thereon.
Glue the above to the frame 5. Next, the etching copper plate 11 is placed above the other
electrode 1 b of the vibrator 1, the contact piece 11 a is soldered, and the etching copper plate
11 is bonded to the side sound insulation body 10. Although not shown, the etching copper
plates 9 and 11 are connected to the core wire 7 of the external extraction cable. The above
structure is integrally molded with, for example, polyurethane rubber 8. As described above,
according to the manufacturing method of the present invention, the positioning of the a vibrator
can be made strict and easy. b You do not have to prepare a good lead wire. C soldered area
reduced to half. Because it is integrated, the side sound insulators do not need to be wound
around individual vibrators. There are remarkable effects such as

complex type transducer, (G) is a perspective view of a transducer unit, and (B) is a transducer
incorporating a transducer unit. 2 (C) is a side sectional view thereof, and FIG. 2 is an exploded
perspective view showing steps of the manufacturing method of the present invention.
