Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker box for audio equipment.

[0002]

2. Description of the Related Art In recent years, a novel design is required for a front panel of a speaker box, so that a speaker using a three-dimensional curved surface has become popular. For the front panel of such a speaker, a resin molded product that is easy to mold into a three-dimensional curved surface and is inexpensive is often used.

An example of the above-mentioned conventional speaker box will be described below with reference to the drawings.

FIG. 3 is an exploded perspective view of a conventional speaker box. In FIG. 3, 1 is a box-shaped wooden box made of particle board, 2 is a molded front panel made of resin such as polystyrene that is attached so as to cover the front opening of the wooden box 1, and the panel joint surface of the wooden box 1 Then, the molded front panel 2 is fitted and the wood screws 3 are fixed.
Reference numeral 4 is a net catch rubber for fixing a net frame attached to the front surface of the molded front panel 2 and having a stretched net.

Next, the fitting portion between the wooden box 1 and the molded front panel 2 will be described in detail. FIG. 4 is a cross-sectional view of an essential part showing a fitting portion between the wooden box 1 and the molding front panel 2, 1 is a wooden box made of particle board, 1a is a surface layer portion thereof, 1c is a middle layer portion, 1c is a molding portion. A joining surface with the front panel, 1d is a cutout apex, and 1e is a cutout for fitting the molded front panel 2. Reference numeral 2 is a molded front panel fitted in the cutout portion 1e of the wooden box 1, 2a is a cutout portion on the surface, 2b is a joint surface with the wooden box 1, 2c is a rounded corner provided for improving the fitting property. It is a department.

[0006]

However, in the conventional speaker box as described above, particle board is usually used as the material of the wooden box 1 of the speaker box as described above, and this particle board has a surface layer portion. 1a is made of fine wood pieces, and the middle layer 1b is made of coarse wood pieces.

Therefore, as shown in FIG. 5, when the molded front panel 2 and the wooden box 1 are fitted to each other, the wood piece 1f scraped off from the middle layer portion 1b made of rough wooden pieces is joined to the joint surface 2b of the molded front panel 2 and the wooden box. When entering the joint surface 1c of No. 1 and creating a gap δ, the commercial value of the appearance is reduced, or work is performed with care so that wood chips do not scrape off. If a gap δ occurs, repeat the work. There is a problem that the cost is increased due to the high difficulty of the fitting work.

In view of the above-mentioned conventional problems, the present invention is a speaker box capable of improving the commercial value of the appearance without a gap in the fitting portion of the molded front panel and the wooden box and reducing the cost by improving the assembling workability. It is intended to provide.

[0009]

In order to solve the above-mentioned problems, a speaker box of the present invention comprises a box-shaped wooden box made of particle board and a cutout of the wooden box so as to cover the front opening of the wooden box. In a speaker box consisting of a molded front panel made of a resin molded product that is fitted and attached to a molded part, a cutout is provided on the inner surface of the wooden box joint part of the molded front panel, and the molded front panel is fitted to the wooden box. It is characterized in that a cavity for storing a piece of wood scraped off from a particle board is formed by the cutout portion of the molded front panel and the cutout portion of the wooden box when combined.

[0010]

According to the present invention, according to the above construction, the wood chips scraped off when the wooden box and the molded front panel are fitted to each other are provided on the inner surface of the wooden box joint portion of the molded front panel and the wooden box. It is housed in the cavity formed by the cutout portion, and there is no gap between the molded front panel and the wooden box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the speaker box of the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a sectional view of a main part of a speaker box according to an embodiment of the present invention after assembly. Figure 2
FIG. 3 is a sectional view of a main part of a speaker box before assembling according to an embodiment of the present invention. The exploded perspective view of the appearance of the speaker box of the present invention is the same as that of FIG. 3, and the description thereof will be omitted.

In FIGS. 1 and 2, reference numeral 1 is a wooden box of a speaker box made of particle board, 1a is a surface layer portion of a wooden box body plate forming the wooden box 1, and 1b is a wooden box forming the wooden box 1. It is the middle layer of the body plate. Particleboard is usually used as the material for the wooden box of the speaker box as described above. In this particle board, the surface layer portion 1a is made of fine wood pieces, and the middle layer portion 1b is made of coarse wood pieces. Further, 1c is a wooden box cutout lower surface portion that abuts on the joining surface of the molded front panel, 1d is a wooden box cutout top portion, and 1e is a wooden box cutout portion for fitting the molded front panel. The wooden box 1 has the same structure as the conventional example.

Reference numeral 2 is a molded front panel made of a resin molded product such as polystyrene and fitted and attached so as to cover the front opening of the wooden box 1, 2a is a surface cutout portion of the molded front panel, and 2c is wood. The joint surface 2d that contacts the wooden box cutout lower surface portion 1c of the box 1 is a rounded portion. Reference numeral 2e denotes a cutout portion provided on the inner surface of the joint portion of the molded front panel 2, which is a portion different from the conventional example.

Then, as shown in FIG. 1, the molded front panel 2 is fitted into the wooden box 1 and the joining surface 2 of the molded front panel 2 is joined.
When c is assembled so as to abut the wooden box cutout lower surface portion 1c, a cavity 13 which is not visible from the surface due to the cutout portion 2e provided on the inner surface of the joint between the wooden box cutout portion 1e and the molded front panel 2 Is formed.

By the wooden box cutout portion 1e provided for fitting the molded front panel 2, the wooden box cutout apex that first comes into contact with the molded front panel 2 when the molded front panel 2 is fitted. 1d and the coarse wood piece 1f of the middle layer portion 1b are scraped off. The scraped wood piece 1f is a wooden box cutout portion 1e.
A cutout 12 provided on the inner surface of the joint between the molded front panel 2 and
It is housed in the cavity 13 formed by b. Therefore, according to the present embodiment, the scraped wood pieces 1f generated when the molded front panel 2 and the wooden box 1 are fitted together are the molded front panel 2.
It is possible to prevent a gap from being generated between the molding front panel 2 and the wooden box 1 without being sandwiched between the joining surface 2c of 1 and the wooden box cutout lower surface portion 1c of the wooden box 1.

[0017]

As described above, the speaker box of the present invention is mounted by fitting the box-shaped wooden box made of particle board and the cutout portion of the wooden box so as to cover the front opening of the wooden box. In a speaker box comprising a molded front panel made of a resin molded product, a cutout portion is provided on an inner surface of a wooden box joining portion of the molded front panel, and the molded front panel is fitted to the wooden box. The cutout portion of the panel and the cutout portion of the wooden box form a cavity for storing the wooden piece scraped off from the particle board, whereby the wooden piece scraped at the time of fitting the wooden box and the molding front panel into a cavity. Since it can be stored, the gap between the molded front panel and the wooden box can be eliminated, improving the product quality of the appearance of the speaker box and improving the fitting workability. It can be achieved down.
