  The speaker 1 is not fixed by a screw or a clamping member, but is fixed to a plate-like portion 63 serving as an attachment portion by an elastic body 5 and will be described below.

  As shown in FIGS. 2 and 3, the elastic body 5 is formed by bending a thin metal plate in this embodiment, and includes a rear piece 51 that contacts the rear surface of the housing 2, and the rear piece 51. A side piece 52 that is provided continuously and contacts the side surface of the housing 2, and an elastic protrusion 53 that is provided continuously from the side piece 52 and functions as a leaf spring. The rear piece 51 is a flat plate having a substantially rectangular shape when viewed from the front. The rear piece 51 is in contact with the rear surface (rear surface) of the housing 2 and is bent at one side edge of the rear surface of the housing 2 so that the front side from this portion is It is a side piece 52. The side piece 52 is a flat plate having a substantially rectangular shape when viewed from the side. The side piece 52 is bent at the front end side, and the tip of the side piece 52 is an elastic protrusion 53. The elastic protrusion 53 is bent obliquely outward and rearward from the front end side of the side piece 52, and is further bent obliquely inward and rearward in the middle of the elastic protrusion 53 to have a substantially mountain shape toward the lateral outer side in plan view. Therefore, the amount of protrusion of the elastic protrusion 53 from the side surface of the housing 2 is elastically changed by the elastic force in each bent portion. At least one elastic body 5 is provided on either the upper, left, or right side of the housing 2. In this embodiment, the elastic body 5 is provided on each of the left and right sides.

  In this embodiment, the elastic body 5 is fixed to the housing 2 by press-fitting and screw fixing. As shown in FIG. 3, the side piece 52 of the elastic body 5 is provided with a fixed piece 54 on the top and bottom in the vicinity of the front end portion, and on the side corresponding to the fixed piece 54 on the side surface of the housing 2. The insertion piece 21 is substantially L-shaped in a rear view and the fixing piece 54 is inserted into the groove 22 inside the groove 22 so that the grooves 22 face each other vertically. The elastic body 5 slides the side piece 52 from the rear to the front along the side surface of the housing 2 to which the side piece 52 is attached, and the upper and lower fixed pieces 54 of the side piece 52 are inserted into the upper and lower parts of the housing 2. It fits into the groove 22 of the piece 21. Here, a bulging portion 55 is formed in the fixed piece 54, and the bulging portion 55 is press-fitted in a state of being stretched against the inner wall of the groove 22. When the rear piece 51 comes into contact with the rear surface of the housing 2 by sliding the elastic body 5 forward, the slide is stopped, and a fixing tool 57 such as a screw is inserted into the fixing tool insertion hole 56 formed in the rear piece 51. Fixing to the housing 2 completes fixing of the elastic body 5 to the housing 2.

Next, attachment of the speaker 1 with the elastic body 5 attached to the plate-like portion 63 will be described. As shown in FIGS. 6B and 5, the above-described mounted openings 64 are formed in the diagonal front portions on both the left and right sides of the plate-like portion 63 that forms the cover portion 62 of the toilet 6. The mounted opening 64 has a shape that is slightly larger than the shape of the housing 2 in a front view, and the housing 2 of the speaker 1 can be inserted therethrough. In a state where the elastic body 5 is attached to the housing 2, when no force is applied to the elastic protrusion 53 of the elastic body 5 (that is, in a natural state), the top 53 a of the elastic protrusion 53 from the housing 2. The width L _{1 of} the portion of the housing 2 where the elastic protrusion 53 is provided (ie, the distance between the top portions 53a of the left and right elastic protrusions 53 in this embodiment, see FIG. 1) corresponds to this portion. a greater state than the width L ₂ of the mounting opening 64. But the attachment of the spring arms 53 when it is pressed into the housing 2 side projecting amount elastically deformed becomes smaller accordingly, the width L ₁ of the portion provided with the elastic protrusion 53 of the housing 2 corresponds to the portion The housing 2 is inserted smaller than the width L _{2 of the} opening 64. In this embodiment, since the elastic protrusion 53 has a substantially mountain shape on the lateral outer side, the housing 2 is covered from the front side (lower side in the figure) of the plate-like part 63 as shown in FIG. If it is inserted into the mounting opening 64, the elastic protrusion 53 abuts against the edge 64a of the mounted opening 64 and is pressed toward the housing 2, and the protrusion amount of the top 53a of the elastic protrusion 53 from the housing 2 is small. Then, the amount of protrusion of the top 53a of the elastic protrusion 53 from the housing 2 increases as the end 64a of the attached opening 64 is overcome and further inserted. When the flange portion 3 of the speaker 1 comes into contact with the front surface of the plate-like portion 63 at the periphery of the attached opening 64 and the insertion is completed, the elastic protrusion 53 becomes a plate-like portion as shown in FIG. It returns to the natural state on the rear side of 63 and is locked and fixed to the mounted opening 64, preventing the housing 2 from dropping forward from the mounted opening 64, and mounting the speaker 1 to the plate-like portion 63 is completed. . In the present embodiment, the flange portion 3 abuts the front surface of the plate-like portion 63 at the periphery of the attached opening 64 via the packing P. In this embodiment, the plate-like portion 63 is provided with a locking rib 64b projecting rearward from the edge 64a of the attached opening 64, and elastically protrudes from the rear end of the locking rib 64b. The part 53 is locked.

  Further, in order to remove the speaker 1 attached to the plate-like portion 63, the speaker 1 is pulled out forward, and only the moving direction of the speaker 1 is reversed from that of the attachment described above, as shown in FIG. From the state, the substantially protrusion-shaped elastic protrusion 53 climbs over the end edge 64a of the attached opening 64, and is drawn to the front side of the plate-like portion 63 as shown in FIG. Removed. In the present embodiment, as shown in FIG. 4, a removal rib 13 protrudes in front of the housing 2 so as to surround the middle / high sound output portion 11 and the bass output portion 12, and the speaker is grasped by grasping the removal rib 13. 1 can be pulled forward.

  According to such a configuration, when the device is attached to the plate-like portion 63, the elastic body 5 is elastically deformed and climbs over the end edge 64a of the attached opening 64, and then returns to the original natural state so that the elastic body 5 is covered. The speaker 1 can be attached in one operation by being locked and fixed to the attachment opening 64, and workability can be improved. Further, as in the case of fixing with screws, the strength of the plate-like portion 63 to be attached is required, and there is no restriction on the material, and pre-processing such as a screw pilot hole is required. There is no need for work. Further, unlike the case of fixing with a clamping member, it is necessary to work by placing the clamping member on the rear side of the plate-like portion 63, and there is no need for labor. In addition, it is possible to reduce the cost by reducing the fasteners and clamping members such as screws for attaching the housing 2 to the plate-like portion 63.

  Further, the fixing of the elastic body 5 to the housing 2 by the fixing tool 57 is performed by fixing the elastic body 5 to the rear surface of the housing 2 through the fixing tool insertion hole 56 formed in the rear piece 51 of the elastic body 5. The fixing tool 57 does not need to be fixed to the side surface, and the fixing tool 57 is not caught when the housing 2 is inserted into the mounted opening 64.
