DETAILED DESCRIPTION OF THE PROBLEM The present invention relates to a speaker mounting
apparatus, in particular, to a speaker mounting apparatus for mounting a speaker in a receiving
case or a heavy equipment case. Conventionally, in order to imitate the speaker inside the case, a
cylindrical body fitted with the outer circumference of the yoke of the speaker is provided
integrally with the inner frame formed by molding, and the outer peripheral portion of the yoke
is fitted in the cylindrical body After that, attach the case and hold down the outer
circumferential flange of the speaker with the same case, or provide a plurality of protrusions
integrally on the inner surface of the case molded in Moh-1 sakura, I used to hold back the outer
flange of the speaker with a metal fastener. Next, an example of an attachment device using this
fastener will be described with reference to the drawings. FIG. 1 shows a case where a plurality
of protrusions 4 for speaker attachment are provided on the inner surface of the case (not
shown) I have nine. The speaker 2 is disposed between the plurality of protrusions 4, and then
the base portion of the fastening tool 3 is fastened to each of the projections 4 with a screw 5. At
this time, the speaker 2 is attached to the case by pressing the outer circumferential flange
portion 2a of the speaker 2 by the distal end portion of each fastening fitting 3. However, this
attachment means not only requires a space for providing the protruding portion 4, but also
many parts are required for attaching the speaker, and the number of steps for attachment also
increases, and the speaker 2 Case ((Because it is an installation speaker, it is a drawback that it

causes chattering due to resonance phenomenon when speaker 2 emits sound. In addition, the
above-mentioned attachment means for providing the tubular body in the middle frame also has
the following advantages: -2 = radiation: not only space is taken in the tubular body, but also
when the speaker is not sufficiently pressed down by the case, This means is also not preferable.
It is an object of the present invention to provide a speaker with an elastic frame body provided
with a groove along the peripheral flange portion of the speaker on the inner peripheral surface.
It is possible to attach a speaker easily and to eliminate the disadvantage of the conventional
attachment device to the brothers. 1 Hereinafter, the present invention will be described with
reference to an illustrated embodiment. FIG. 2 is an exploded perspective view of the speaker
mounting apparatus according to the present invention, in which the speaker 12 is attached to
the speaker mounting position on the inner surface 11 a of the case 11. To the speaker attaching
position, the elastic attachment frame body 13 is attached by adhesion or the like. In this elastic
mounting frame body 13i'l, in this embodiment, rubber or (d flexible synthetic resin material,
which is formed in a ring shape and has an inner diameter of the ring formed by the outer
peripheral flange portion 12a of the speaker 12 It is formed smaller than the diameter, or \ 3 lug.
A groove 13 a is provided along the outer circumferential flange 12 a of the speaker 12 on the
inner peripheral surface of the elastic mounting frame 13. Also, while cutting the groove 13a. As
shown in FIG. 3, as it goes to the inner part of the groove, it is inclined so as to widen its width.
The elastic mounting frame body 13 formed in this manner is first adhered to the speaker
mounting position of the inner surface 11 a of the case 11 by adhesion or the like, and then, in
the groove 13 a of the frame body 13, As shown in FIG. 4, the outer peripheral flange 12 a of the
speaker 12 is fitted, whereby the speaker 12 is attached to the case 11. At this time, the inclined
surface portion of the groove 13 a presses the outer peripheral flange portion 12 a of the
speaker 12 by the elastic action. Therefore, the speaker 12 is firmly supported without being
rattled to the case 11 ((against the case 11). In the above embodiment, the elastic mounting
frame 131 and the outer circumference flange 12a of the speaker are formed in a ring shape so
that the entire periphery thereof is fitted. However, this is formed to be slightly larger than the
half circle, Of course, it may be composed of a plurality of partial arcuate shapes. Of course, it is 4 = deaf. And, in the case where it is configured to have an arc shape slightly larger than the
semicircle shape (in (-), by inserting the speaker collar portion to the groove on the inner
peripheral surface sideways 75), it is possible to support the speaker in the elastic mounting
frame it can. As described above (according to the speaker mounting device of the present
invention, since the elastic mounting frame body 13 is merely fixed to the speaker mounting
position, the space occupied by the speaker mounting is remarkably small, and , The speaker is
supported by the elastic member, so even when i sound is emitted, it does not distort a cooccurrence phenomenon by its jogging action. In addition, since the number of parts for
mounting is only the elastic mounting frame L * 13, it is extremely few, and the mounting
process is simple with non-fingers. Even if it is made of case or metal, you can also attach the

speaker without taking out unsightly 1 spot welding etc. outside it. Therefore, according to the
present invention (according to the present invention, it is possible to provide mounting and
mounting of a speaker which solves the disadvantage of the conventional speaker mounting
apparatus to his brother). ト
