DESCRIPTION JPH0568198
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker mounting structure, and more particularly to a speaker having a frame made of synthetic
resin and mounted at a predetermined position by a mounting portion provided on the frame.
The mounting structure of the speaker.
[0002]
2. Description of the Related Art For example, a radio receiver is provided with a speaker, which
reproduces an audio signal. A speaker mounting portion is provided at a predetermined position
of the front cabinet, and the speaker is mounted to this mounting portion. In order to attach the
speaker to the front cabinet, an attachment portion is provided on the speaker side, and the
attachment portion is attached and fixed to the front cabinet by, for example, a screw.
[0003]
[0003] The conventional speaker mounting portion for mounting to the front cabinet is integral
with the frame and has a rigid structure. And it is made to attach to a front cabinet, without
bending such an attaching part. Therefore, due to the variation in the dimensions of the speaker
and the cabinet, the pressure contact of the speaker with respect to the front cabinet is
insufficient, which causes a so-called “flirt”.

[0004]
The present invention has been made in view of such problems, and absorbs variations in the
dimensions of the mounting portion of the speaker and the front cabinet, thereby securely
mounting the speaker in a state of pressure contact with the front cabinet It is an object of the
present invention to provide a speaker mounting structure as described above.
[0005]
SUMMARY OF THE INVENTION The present invention is a speaker having a frame made of
synthetic resin, which is mounted at a predetermined position by an attaching portion provided
on the frame. The present invention relates to a speaker mounting structure characterized in that
a stress absorbing portion for absorbing stress by elastic deformation is provided at a root
portion of the mounting portion.
[0006]
Therefore, if the mounting portion is mounted at a predetermined position by means of a screw
or the like, the stress absorbing portion provided at the root portion of the mounting portion is
elastically deformed, which causes the frame and mounting of the speaker to be mounted. It
becomes possible to absorb variations in position dimensions, and the speaker is securely
mounted in a state of being in pressure contact with a predetermined mounting position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the structure of a
compact radio receiver according to an embodiment of the present invention, wherein the upper
side of a front cabinet 10 constituting the casing of the radio receiver is horizontally elongated.
Window 11 is formed.
A speaker mounting portion 12 is formed on the lower right side of the window 11 and inside
the front cabinet 10.
The speaker mounting portion 12 is formed with an opening 13, and a rib 14 is provided to cross
the opening 13.

The speaker mounting portion 12 is surrounded by the ring-shaped projection 15. Further, a pair
of mounting seats 16 are formed on the outside of the ring-shaped projection 15, and the
speaker 20 is fixed by these mounting seats 16.
[0008]
As shown in FIGS. 1 and 2, the speaker 20 has a flat disk shape, and its outer casing is formed of
a circular mold frame 21. A pair of attachment portions 22 are formed symmetrically on the
outer peripheral side of the mold frame 21. The attachment portions 22 project toward the outer
periphery, and the attachment portions 22 are formed with small holes 23 through which screws
are inserted.
[0009]
A printed wiring board 24 is attached to the inner side of the front cabinet 10 on the rear side of
the position where the speaker 20 is attached. A cut 25 is formed on the lower right side of the
printed wiring board 24 as shown in FIG. 1, and the drive section 26 of the speaker 20 is
removed by the cut 25. The drive unit 26 drives the diaphragm 27 in the mold frame 21 shown
in FIG. In addition, the printed wiring board 24 is provided with an LCD display unit 28.
[0010]
A thin portion 31 is formed on the root side of a pair of mounting portions 22 provided on the
outer peripheral side of the mold frame 21. The thin portion 31 constitutes a stress absorbing
portion, and absorbs the stress when the mounting portion 22 is elastically deformed when the
screw 32 is tightened and fixed.
[0011]
FIG. 3 shows the mounting of the mold frame 21 of the speaker 20 to the speaker mounting
portion 12 of the front cabinet 10, and the outer peripheral side of the mold frame 21 is fitted to
the inside of the ring-shaped projection 15. In the engaged state, screws 32 are screwed in as
12-04-2019
3
shown in FIG. 4 so as to pass through the small holes 23 of the mounting portion 22. Here, a selftapping screw is used as the screw 32, and a female screw is formed while screwing the screw 32
into the small hole of the mounting seat 16.
[0012]
At this time, since a small gap A is formed between the upper end of the mounting seat 16 and
the lower surface of the mounting portion 22 as shown in FIG. 3, when the screw 32 is screwed
in, the mounting portion 22 The thin portion 31 is elastically deformed, and the mounting
portion 22 is fixed in a state where the lower end thereof is in contact with the edge portion of
the mounting seat 16 in an inclined state.
[0013]
Therefore, according to such a structure, the influence of the variation of the dimension of the
mold frame 21 of the speaker 20 or the variation of the dimension of the mounting seat 16 of
the front cabinet 10 is eliminated, and the speaker 20 is reliably front cabinet. It becomes
possible to fix to ten.
[0014]
As described above, in the radio receiver according to the present embodiment, the speaker
mounting portion 12 of the front cabinet 10 is provided with the mounting seat 16 consisting of
a pair of bosses.
Therefore, the speaker 20 is disposed inside the ring-shaped projection 15, and the screw 32 is
passed through the small hole 23 of the mounting portion 22 provided on the mold frame 21 of
the speaker 20, and the screw 32 is fastened to the mounting seat 16. Thus, the speaker 20 can
be attached to the cabinet 10.
[0015]
When the speaker 20 is placed on the speaker mounting portion 12 of the front cabinet 10, a
slight gap A is provided between the lower surface of the mounting portion 22 and the mounting
seat 16 as shown in FIG.

When the screw 32 is tightened in this state, the thin-walled portion 31 provided in the
mounting portion 22 is bent, and the speaker 20 is mounted on the cabinet 10 as shown in FIG.
For this reason, even if the dimension B in FIG. 3 changes due to the variation of the dimensions
of the speaker 20 and the cabinet 10, the contact portion between the speaker 20 and the
cabinet 10 is surely crimped.
[0016]
Therefore, according to such a radio receiver, the elasticity of the thin portion 31 formed at the
root portion of one or more attachment portions 22 integrally provided with the mold frame 21
of the speaker 20 can be obtained. A speaker 20 which can be used and can be bent relative to
the frame 21 is obtained. By bending the mounting portion 22 in this manner, variations in the
dimensions of the speaker 20 can be absorbed, and the speaker 20 can be reliably crimped to the
surface of the speaker mounting portion 12 of the front cabinet 10.
[0017]
As a configuration for enabling deformation of the root portion of the mounting portion 22
formed on the mold frame 21 of the speaker 20, a slit 34 as shown in FIG. 5 may be provided
instead of the thin portion 31. You may Alternatively, as shown in FIG. 6, the narrow portion 35
may be formed on the root side of the attachment portion 22, and the attachment portion 22
may be deformed by the narrow portion 35.
[0018]
As described above, according to the present invention, the stress absorbing portion for
absorbing stress by elastic deformation is provided at the root portion of the mounting portion of
the synthetic resin frame of the speaker. Therefore, it is possible to attach the speaker to a
predetermined position by the attachment portion while elastically deforming the stress
absorbing portion formed at the root portion of the attachment portion, thereby absorbing the
variation in dimensions of the attachment position side or the frame of the speaker. , It becomes
possible to attach in the state which pressure-contacted the speaker reliably to the attachment
position. This prevents the speaker from being flickering during playback.
