Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a speaker mounting device that can be used for telecommunications equipment etc. equipped with speakers.

Structure of a conventional example and its problems FIG. 1 shows an exploded perspective view of a conventional speaker mounting device. In FIG. 1, 1 is a cabinet having a hollow hole 2 and a screw hole 3 formed on the outer periphery of the hollow hole 2, 4 is a speaker bracket having a retaining boss 5 and a speaker mounting boss 6, and 7 is a speaker bracket having a boss 5 for holding the speaker. This is a speaker with a hole 8 provided at its end.

How to fix cabinet 1 and speaker 7 is as follows.
Attach speaker 7 to boss 6 of speaker bracket 4.
Insert the screw 9 into the hole 8 and tighten it to fix it. Then, insert the speaker bracket 4 to which the speaker 7 is fixed from the inside of the cabinet 1.
The screw hole 3 and the boss 6 are brought into contact with the outer periphery of the hollowed-out hole portion 2 so as to match, and the speaker bracket 4 is fixed from the outside of the cabinet 1 with screws 9'.

However, in the above-mentioned conventional configuration, there are many screws for fastening, which increases the number of man-hours.Also, since the side surface of the cabinet 1 is provided with holes such as the hollow hole part 2, the mold of the cabinet 1 becomes complicated, and the opening area is reduced. This has the disadvantage that the strength of the cabinet 1 is extremely weakened because the large hollowed-out hole 2 is required.

OBJECTS OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a speaker mounting device that has a simple structure and is highly productive without impairing the strength of the cabinet.

Composition of the Invention The speaker mounting device of the present invention includes a buttful plate that is larger than the outer diameter of the speaker and has a sound emitting hole in the center and a plurality of locking claws in the peripheral part, and the buttful plate is attached via a bendable rib. a speaker holder, which is formed integrally with the rib and has a notch portion that clamps the outer peripheral portion of the speaker at the end when the rib is bent, and a hole portion that fits into the locking claw at a position facing the locking claw; A cross section L in which a speaker holding plate is inserted and fixed, which is provided opposite to the plate and the inner wall of the cabinet having a plurality of holes for emitting sound, and in which the locking claws fit into the holes and hold the speakers. The structure includes a letter-shaped rib, which increases the strength of the cabinet, reduces man-hours, and improves productivity.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Identical members in FIGS. 2 to 6 are designated by the same numbers. FIG. 2 is an external perspective view of the speaker 7, which has the same structure as the conventional one. Figures 3 to 6
In the figure, reference numeral 10 denotes a double plate that is larger than the outer diameter of the speaker 7 and has a sound emitting hole 10a in the center, 11a and 11b are speaker mounting parts to which the speaker 7 is attached, and 12 and 13 are a double plate 10.
When the ribs 16 are bent, the speaker holding plates 12a and 13a, which are provided at the upper and lower ends via the ribs 16 and are integrally formed with the buttful plate 10,
A notch 14 provided at the end of the speaker holding plates 12 and 13 and holding the outer periphery of the speaker 7;
16 is a locking claw that fits into the hole 15 of the speaker holding plate 12, 13 and fixes the speaker 7 with one action (one touch), and 16 connects the full plate 10 and the speaker holding part 12, 13. , and a bendable rib 17 that functions as a hinge is a positioning pin that is inserted into a hole 8 provided at the peripheral edge of the speaker 7 to determine the position of the speaker 7. Note that the buff-full plate 10, the speaker holding plates 12, 13, and the ribs 16 are integrally molded using, for example, polypropylene.

FIG. 7 is an external perspective view of the cabinet to which the speaker 7 is attached. 18 in Figure 7
is the cabinet, 19 and 20 are the cabinets 18
Ribs 21 having an L-shaped cross section and facing the inner wall are a plurality of holes provided in the center of the cabinet 18 surrounded by the ribs 19 and 20.

A case where the speaker 7 is attached to the cabinet 18 with the above configuration will be explained. First, in order to attach the speaker 7 to the full board 10, insert the positioning pin 17 into the hole 8 of the speaker 7.
After inserting the rib 1 into the hole 15 of the speaker mounting portions 12 and 13 and the locking claw 14,
6, hold the speaker 7, and tighten the locking claw 1.
4 completely into the hole 15, and then remove the speaker 7.
is fixed to the full plate 10.

FIG. 8 is an external perspective view showing a state in which the baffle plate 10 is attached and fixed to the speaker 7. Next, when attaching the speaker 7 fixed as described above to the cabinet 18, the ribs 19, 20 on the inner wall of the cabinet 18 and the buttful plate 10
The speaker 7 can be easily attached to the cabinet 18 by inserting it in the direction of arrow A in FIG. 7 so that the upper and lower ends of the speaker 7 fit together.

As described above, according to this embodiment, there is no need to provide large holes in the side surface of the cabinet 18, and the strength of the cabinet 18 can be increased. Furthermore, since assembly can be done with one touch, the number of man-hours can be reduced, and screws 9, 10, etc. are no longer required, and costs can be reduced.

Effects of the Invention According to the speaker mounting device of the present invention, since it is equipped with a buttful plate that fixes the speaker and can be easily attached to the ribs provided on the inner wall of the cabinet, the strength of the cabinet can be increased without having to make large holes on the side surface of the cabinet. In addition, since assembly can be performed with one touch, the number of man-hours can be reduced, screws, etc. are no longer required, and costs can be reduced and productivity can be improved, which has great effects.
