DESCRIPTION JPH1141692
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
composite speaker used for vehicles and the like.
[0002]
2. Description of the Related Art A conventional composite speaker will be described with
reference to FIG.
[0003]
FIG. 4 is a side sectional view showing the structure of a conventional composite type speaker.
Referring to FIG. 1, reference numeral 1 denotes a field portion, which is composed of an upper
plate 1a, a magnet 1b and a lower plate 1c having a center pole, and the center of the upper
plate 1a and lower plate 1c A magnetic gap 4 is formed in the gap between the pole portions.
Further, 2 is a frame, 5 is a diaphragm coupled around the voice coil 3 coupled to the periphery
of the frame 2 and fitted in the magnetic gap 4, on which the voice coil lead wire 3 a and the
tinsel wire 6 and , And the end of the tinsel wire 6 is connected to the cord connector 8 through
the terminal 7 to constitute a main speaker.

The high-tone speaker 9 is connected to the upper surface of the diaphragm 5 of the main
speaker via the tinsel wire 6 to constitute a composite type speaker.
[0005]
SUMMARY OF THE INVENTION However, in the above-mentioned composite type speaker, after
the cord connector 8 and the input cord 11 from the outside are connected, the cord connector 8
is not engaged with the speaker body and the mounting surface 12 In order to perform this, the
clearance clearance gap 12a of the mounting surface is necessary, and when the speaker
amplitude is from the clearance clearance clearance gap 12a of the mounting surface, the sound
on the back surface of the diaphragm 5 wraps around to the front and causes phase interference
to There was a problem of
[0006]
Furthermore, because the terminal 7 and the cord connector 8 are connected, the number of
parts is large and it is difficult to produce.
[0007]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems,
and provides a composite type speaker in which the installation work is simplified, phase
interference due to sound wrap around is prevented, and excellent sound reproduction and the
number of parts are reduced.
[0008]
SUMMARY OF THE INVENTION In order to solve the above problems, the composite speaker of
the present invention comprises a field section having a magnetic gap, a frame coupled to the top
surface of the field section, and an outer edge of the frame. , A main speaker including a
diaphragm coupled to a center of the voice coil that is embedded in the magnetic gap, a speaker
for high-pitched sound disposed on the diaphragm, and a gasket around the periphery of the
frame And the cord from the voice coil lead wire and the cord from the high-tone speaker are
connected to the terminal portion of the connector, and the connector is a speaker frame front
side of the speaker The connection with the external input cord can be done in the same
direction as the installation of the There is no need to the application surface provided relief
portion clearance cord connector is intended can be prevented even phase interference by
diffraction of sound.

According to a first aspect of the present invention, there is provided a field portion having a
magnetic gap, a frame coupled to an upper surface of the field portion, and an outer edge portion
coupled to the frame. A main speaker including a diaphragm coupled around a voice coil
embedded in the magnetic gap, a speaker for high sound disposed on the diaphragm, and a
connector coupled to the periphery of the frame via a gasket The cord wire connected to the lead
of the voice coil and the cord from the high-tone speaker are connected to the terminal portion of
the connector, and the connector is provided on the front side of the speaker frame, so
Connection with the external input cord can be done in the same direction as the speaker
installation, and installation work is facilitated, and the cord connector on the mounting surface
There is no need to provide the escape portion clearance are those which can also prevent phase
interference by diffraction of sound.
[0010]
According to a second aspect of the present invention, the gasket of the first aspect and the
connector are integrally molded by resin, and the number of parts can be reduced and the
number of assembling steps can be reduced.
[0011]
According to a third aspect of the present invention, the frame, the gasket and the connector of
the high-pitched speaker of the first aspect are integrally molded with a resin, and the number of
parts can be further reduced and the number of assembling steps can be reduced. .
[0012]
Hereinafter, an embodiment of a speaker according to the present invention will be described
with reference to FIGS. 1 to 3.
[0013]
In the description, the same parts as in the prior art will be assigned the same reference
numerals and explanations thereof will be omitted.
[0014]
(First Embodiment) FIG. 1 is a side sectional view of a composite type speaker according to one
embodiment, and only the differences from the prior art will be described with reference to FIG.

[0015]
20 is a gasket coupled to the outer peripheral edge of the frame 2; 21 is a connector having a
terminal portion 21a coupled onto the gasket 20; and a cord 22 having one end connected to the
high sound speaker 9 at the terminal portion 21a. Are connected, and the other end of the tinsel
cord 6 whose one end is connected to the lead wire 3a of the voice coil 3 is also connected to
form a composite type speaker.
[0016]
As described above, since the connector 21 is provided on the front side of the speaker, although
it is not shown, the external input cord and the connector 21 can be connected in the same
direction as the mounting of the speaker, which facilitates the mounting operation. Since it is not
necessary to set the clearance for the cord connector on the mounting surface, it is possible to
prevent phase interference due to sound wrap around.
[0017]
(Second Embodiment) FIG. 2 is a side sectional view of another embodiment of the present
invention. The same parts as those of the first embodiment are designated by the same reference
numerals and their description will be omitted.
[0018]
According to this figure, the difference from the first embodiment is the connector portion 31,
and in the present embodiment, the connector portion 31 is formed by integrally molding the
gasket and the connector with resin.
[0019]
As a result, the number of parts can be reduced, and the productivity can also be improved.
[0020]
(Third Embodiment) FIG. 3 is a side sectional view of another embodiment of the present
invention. The same reference numerals as in the first embodiment denote the same parts, and a
description thereof will be omitted.
[0021]
According to the drawing, the difference from the first embodiment is that a speaker frame is
formed by integrally molding the frame of the high-pitched speaker 9 and the connector of the

main speaker and the gasket with a resin.
[0022]
According to the above configuration, the frame of the high-sound speaker, the connector of the
main speaker, and the gasket are integrally formed of resin, thereby significantly reducing the
number of parts.
The number of parts can be reduced and the number of operation steps can be reduced even by
integrating only the frame of the high-sound speaker and the connector of the main speaker.
[0023]
As described above, in the composite type speaker according to the present invention, the
connection work can be facilitated because the external input cord and connector can be
connected in the same direction as the mounting of the speaker, and the cord can be mounted on
the mounting surface. Since it is not necessary to set the clearance gap of the connector, it is
possible to prevent phase interference due to sound wrap around, and to improve productivity.
