Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a decorative plate mounting device for connecting a front decorative plate and a cabinet body in a speaker cabinet belonging to the field of electroacoustic equipment.

[Prior Art] A typical structure of a conventional mounting device for attaching a cabinet main body and a decorative plate is, as shown in FIG. 5, for example, as shown in FIG. A catcher 21 made of an elastic material such as rubber or synthetic resin and having a flange portion 21a on the outer peripheral edge of the opening and a plurality of gripping protrusions 21b on the inner surface of the cylindrical portion.
is attached to the hole with the opening aligned with the front surface of the cabinet, and on the other hand, a retainer made of synthetic resin or the like is installed on the back side of the decorative plate 23 covering the front surface of the cabinet 22 at a position corresponding to the catcher 21. The decorative plate 23 is removably attached to the cabinet by attaching the locking projection 24, inserting the locking projection 24 into the catcher 21, and pressing it against the protrusion 21b.

[Problem to be solved] The conventional decorative plate mounting device having this structure is difficult to use, for example, in order to avoid deterioration of sound reproduction quality due to the decorative plate, so that the speaker system is used with the decorative plate removed. In this case, the above catcher 21
The problem is that the openings are exposed and several closed tubes are formed on the front surface of the cabinet 22, and the openings not only worsen the appearance, but also cause the closed tube portions to resonate and deteriorate the frequency characteristics. It was hot.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art by creating a structure in which the opening of the catcher is automatically closed when the decorative plate is removed.

[Means for Solving the Problems] The decorative plate attaching device according to the present invention for achieving the above object will be explained using FIGS. 1 to 3 showing embodiments. Alternatively, it is made of a material such as a synthetic resin having elasticity, and includes a cylindrical main body part 1e and an elastic part 1c attached to the bottom part.
and a closing disc 1d formed at the upper end of the expandable part 1c so as to be flush with the upper edge of the cylindrical body part 1e. The cylindrical main body 1e is attached to the main body with the upper edge thereof substantially aligned with the front surface of the cabinet. The decorative plate 3 is formed by inserting the locking protrusion 4 configured to press against the inner wall of the catcher 1 into the catcher with the closing disc 1d of the catcher 1 pushed in and press against the inner surface of the cylindrical main body portion 1e. It has a configuration that allows it to hold.

[Function] In the decorative plate mounting device having this configuration, when the decorative plate 3 is removed, the closing disc 1d that has been pushed deep into the catcher 1 by the locking protrusion 4 is removed from the catcher. It returns to its original opening position by the repulsive force of the expandable part 1c provided inside the cabinet, and becomes flush with the front surface of the cabinet, eliminating the formation of a closed tube that causes resonance and also reducing the appearance. prevent.

[Embodiment] Referring to FIGS. 1 and 2, the first embodiment of the present invention will be described in detail. Small cylindrical locking protrusions 4 are provided at multiple locations (six locations in this embodiment) on the back surface of the decorative plate 3. is attached, and on the other hand, a mounting hole is provided on the front surface of the cabinet 2 at a position corresponding to the locking protrusion 4 attached to the decorative plate 3, and the rear part of the catcher 1 is inserted into the mounting hole. installed.

The catcher 1 is manufactured by molding rubber, and has a cylindrical shape with a bottom as shown in FIG. The side surface has a plurality of protrusions 1b for gripping the locking projection 4 by being pressed against the side surface of the locking projection 4 when the locking projection 4 of the decorative plate 3 is inserted, and the bottom portion has a plurality of protrusions 1b. A flexible stretchable part 1c is formed of the same material to be extremely thin, and the cylindrical main body part 1 is formed at the upper end of the stretchable part 1c.
A closed disk 1 integrally formed from the same material so as to be flush with the upper edge of e, that is, the flange portion 1a.
d is held by the elastic part 1c.

When the decorative plate 3 is attached to the cabinet 2, as shown in FIG. The locking protrusion 4 and the protrusion 1b pressed against the locking protrusion 4
The decorative plate 3 is held by the frictional force between the decorative plate 3 and the decorative plate 3.

Fig. 4 shows a second embodiment of the present invention, in which the extendable part 1c of the catcher 1 is made into a separate member, and the lower end is glued to the bottom of the catcher 1 with a cylindrical shape made of highly flexible foamed urethane resin, and the upper end is made into a separate member. It has a structure in which a closing disc 1d made of a member is attached.

This second embodiment has the effect of improving the appearance by giving the upper surface of the closing disk 1d the same finish as the front surface of the kibine net.

As another modification, the convex strip 1b on the inner surface of the catcher 1 of each of the above embodiments is omitted, and instead, the locking protrusion 4 is divided in the axial direction and elasticity is imparted in the diametrical direction by the cut. It is also possible to have a structure (not shown in the drawings) in which the elasticity causes pressure contact with the inner wall of the cylindrical main body 1e when inserted into the cylindrical main body 1e.

As mentioned above, the embodiments of the decorative plate attaching device according to the present invention are not limited to the structure of the above-mentioned embodiments. For example, the structure of the expandable part may use a spring or the like, or it may be integrally molded. As long as it has the above-mentioned constituent elements of the present invention, such as processing the upper surface of the closing disc 1d so that it has a finish that matches the front surface of the cabinet, has the function described in the present invention, and has the effects described below, It can be implemented with appropriate modifications.

[Effects] The decorative plate mounting device according to the present invention has the following effects.

(1) When the decorative plate is removed and used for the purpose of improving reproduction sound quality, the catcher opening is closed by the closing disc, and a recess similar to a closed pipe by the catcher is not formed on the front surface of the cabinet. Therefore, deterioration of frequency characteristics due to resonance of the recessed portion does not occur.

(2) Since the catcher opening is not exposed, the appearance is good.

Due to the above advantages, it is possible to provide a speaker system that is visually superior, has good sound quality, and has high commercial value.
