DESCRIPTION JP2002135873
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker apparatus mainly used as a door mount of an automobile, which can be easily attached
to and removed from a speaker attachment section of the door, and the attachment section of the
door and the speaker The present invention relates to a speaker device that can ensure sealing
between devices.
[0002]
2. Description of the Related Art A prior art will be described with reference to a cross-sectional
view of FIG.
[0003]
According to the figure, reference numeral 1 denotes a speaker device, and an end portion of the
speaker mounting hole 5 is provided on the mounting surface 4 of the door with the claw 3
formed inside the outer peripheral portion of the resin frame 2 of the speaker device 1 To insert
into the clip insertion hole 7 one-sided clip 6 provided by resin molding integrally with the frame
2 inside the outer peripheral part of the frame 2, and elastically deform the upper free end side
end It can be attached to the attachment surface 4 by dropping it at the step 6a.
[0004]
Further, when removing the speaker device 1 from the mounting surface 4, a removal jig (not
shown) is inserted from the gap A between the frame 2 and the mounting surface 4, and the end

of the free end of the clip 6 By removing the fitting between the clip 6 and the end face of the
clip insertion hole 7 and pulling the speaker device 1 in the B direction to remove it from the
mounting surface 4.
[0005]
In addition, 8 is a sealing material provided on the entire periphery of the outer peripheral part
of the frame 2, thereby making the speaker device 1 and the mounting surface 4 in close contact
with each other mainly to prevent air leakage (the rear of the speaker device 1 It is used as an
anti-vibration material or the prevention of the wraparound of the sound to the front.
[0006]
However, in the above-described conventional configuration, when the speaker device 1 is
removed from the mounting surface 4, a removal jig is inserted from the gap A between the
frame 2 and the mounting surface 4 It is necessary to apply a force to the clip 6 to deform the
clip 6.
Therefore, if the gap A between the frame 2 and the mounting surface 4 at the place where the
removal jig is inserted is reduced in order to improve the sealing performance of the frame 2 and
the mounting surface 4, the removal jig is difficult to insert. It was difficult to remove it, and on
the contrary, it had a problem that the sealability was lost if it was enlarged.
[0007]
The present invention solves the above-mentioned conventional problems, and provides a
speaker device capable of easily attaching and detaching the speaker device to and from the
mounting surface of the speaker and ensuring sealing between the mounting surface and the
speaker. The purpose is to
[0008]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention
according to claim 1 of the present invention particularly forms a hole in the frame in which the
clip can be manipulated from the front, and further closes the hole. Since a lid is provided and it
is not necessary to provide a gap for clip operation between the frame and the mounting surface,
a sealed state between the mounting surface and the frame of the speaker device is secured
compared to the conventional one. The sound quality can be improved, and the speaker device

can be removed simply by removing the lid and operating the clip, and the operability of the
conventional attachment and detachment can be maintained.
[0009]
In the invention according to claim 2 of the present invention, since the lid according to claim 1
is integrally formed on the outer peripheral portion of the frame by resin molding, the number of
parts is increased and the cost is not increased. It is possible to make a speaker device excellent
in quality.
[0010]
The invention according to claim 3 of the present invention is that the inner side of the lid
according to claim 1 is provided with a protrusion fitted into the inside of the U-shaped clip, and
deformation of the clip due to external force applied to the clip. Can be prevented.
[0011]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present
invention will be described below with reference to FIGS.
In the description, the same parts as in the prior art will be assigned the same reference
numerals and explanations thereof will be omitted.
[0012]
(First Embodiment) FIG. 1 (a) is a side sectional view of a speaker device according to a first
embodiment of the present invention, and FIG. 1 (b) is a partially enlarged perspective view of
the vicinity of the clip of the frame which is the main part. The speaker device according to claim
1 is mainly described.
[0013]
According to the drawing, the difference from the prior art is that the frame 2 is expanded to the
upper side of the clip 6 and a hole 9 is provided in the portion on the front side of the clip 6 and
the hole 9 is sealed by the lid 10 .
12-04-2019
3
The sealability between the speaker device 1 and the mounting surface 4 is realized by bringing
a seal material 8 provided on the entire periphery of the outer peripheral portion of the frame 2
into close contact with the mounting surface 4.
[0014]
With the above configuration, in the speaker device according to the present invention, the
device to the mounting surface 4 of the speaker device 1 can be performed in the same manner
as in the prior art, the lid 10 is removed from the frame 2 and the removal jig is inserted through
the hole 9 It is performed by deforming the clip 6 by applying a force to the free end of the clip
6, disengaging the clip 6 and the end face of the clip insertion hole 7, and removing the speaker
device 1 from the mounting surface 4 .
[0015]
Therefore, it is not necessary to provide a gap A between the frame 2 and the mounting surface 4
as in the conventional case in order to remove the speaker device 1 from the mounting surface 4.
In addition to being able to seal, the speaker device 1 can be attached and removed easily, the
sealing property between the mounting surface 4 and the speaker device 1 can be ensured.
[0016]
In addition, since the lid 10 is provided with the convex portion 10a which is a slight press-fit fit
with the hole 9, the lid 10 is not detached unless a force for removing the lid 10 from the outside
is applied.
[0017]
(Second Embodiment) FIG. 2 (a) is a side sectional view of a speaker apparatus according to a
second embodiment of the present invention, and FIG. 2 (b) is a partially enlarged perspective
view of the vicinity of the clip of the frame which is the main part. The speaker device according
to claim 2 is mainly described.
[0018]
Referring to this figure, only differences from the first embodiment of FIG. 1 will be described.
Reference numeral 10b denotes a lid integrally molded with the frame 2 via the hinge 11, and
the lid 10b has the first embodiment of FIG. Similarly to the above, a convex portion 10a to be
press-fit fitted in the hole 9 is provided.

[0019]
With the above configuration, in addition to the effects of the first embodiment, there is no
concern that the lid 10b will be lost when the speaker device 1 is detached from the mounting
surface 4 during repair, and the lid 10b is molded as a separate component from the frame 2. It
is possible to reduce the number of parts because it is not necessary to
[0020]
(Third Embodiment) FIG. 3 is a side sectional view of the third embodiment of the speaker
apparatus according to the present invention, and the speaker apparatus according to claim 3 is
mainly described.
[0021]
If only the difference from the first embodiment of FIG. 1 is described with reference to FIG. 10,
10c is a lid provided with a clip deformation preventing projection 10d to be fitted between the
end portions of the clip 6; When attached to the frame 2, in order to prevent deformation of the
clip 6, the connection between the end of the clip 6 and the end of the speaker mounting hole 5
can be made extremely difficult to remove unless the lid 10c is removed first.
[0022]
As described above, according to the present invention, when removing the speaker device, the
lid is opened and the fitting with the mounting surface of the speaker device is released by
applying a force to the clip through the hole closed by the lid. It is not necessary to provide a gap
for inserting a removal jig for removing the speaker device between the speaker device and the
mounting surface, and the speaker device can be easily attached to and removed from the
mounting surface. In addition to the above, it is possible to realize a speaker device that can
ensure sealing between the mounting surface and the speaker device.
