DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker cabinet used for an audio device, and more particularly to a speaker cabinet which can be easily assembled.

[0002]

2. Description of the Related Art FIGS. 3 and 4 are schematic front views showing, for example, a conventional thin speaker system. In FIG. 3 , reference numeral 1 denotes a cabinet main body, and 2 denotes a vertical division of the internal volume of the cabinet main body 1. 3 is a speaker unit attached to the partition plate 2, 4 is a screw for fixing the speaker unit 3, and 5 is a nut. In FIG. 4 , reference numeral 6 denotes a bar for attaching the partition plate 2, reference numeral 7 denotes a screw for fixing the partition plate 2 to the bar 6, and reference numeral 8 denotes a nut.

Next, the operation will be described. In FIG. 3 , a partition plate 2 is provided so as to divide the volume of the cabinet body 1 in the vertical direction. The speaker unit 3 is placed on the partition plate 2, the screw 4 is inserted while holding the unit by hand, and the speaker unit 3 is fixed with the nut 5.

Further, as shown in FIG. 4, previously fixed in advance speaker unit 3 to the partition plate 2, place the partition plate 2 to the crosspiece 6, similarly to FIG. 3, insert a screw 7 while holding by hand, Fix with nut 8.

At this time, the ratio of the width to the height of the cabinet body 1 is generally 1: 2 or more, and the width is usually 100 mm to
In many cases, the work space is narrow, and the work of holding the unit 3 by inserting a hand is not easy. In addition, power tools such as an electric screwdriver and an air screwdriver cannot be used because the space is small. Therefore, the screw 4 and the screw 7 had to be tightened using a hand-held screwdriver.

FIG. 5 shows a speaker device using this speaker cabinet. Reference numeral 9 denotes a baffle plate, which has low-frequency sound reproduction ports 10 and 11 and a medium-high sound reproduction speaker unit 12 attached thereto. Reference numeral 13 denotes a box that acoustically shields the speaker unit 12 for reproducing middle and high frequency sounds.

[0007]

Since the conventional speaker cabinet is constructed as described above, a hand must be inserted into a narrow space, and a power tool cannot be used. Work was very difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and eliminates the work of inserting a hand into a narrow space and holding the unit, and eliminating the screw tightening work in a narrow space, and assembling. An object of the present invention is to provide a speaker cabinet that is easy to work.

[0009]

The speaker cabinet according to the present invention is provided inside each of the opposing side walls of the cabinet body, and has a convex or concave shape extending along the side wall and a guide fitted to each of the guides. It has a concave or convex fitting portion that can be inserted, and is inserted and held in each of the guides, and a partition plate that divides the cabinet body into two, and a speaker unit mounted on the partition plate. A speaker cabinet having an inclined portion for applying a pressing force to a substantially central portion of the partition plate when the partition plate is inserted into the guide, in at least one of the fitting portion and the guide portion. .

[0010]

The cabinet according to the present invention is mounted by inserting a partition plate into a guide on the inner surface of the side wall of the cabinet body and pushing it in.

The guide and the inclined portion provided on at least one of the fitting portions of the partition plate exert a pressing force such that the partition plate is fastened to a substantially central portion of the partition plate when the partition plate is inserted into the guide. And can be firmly attached .

[0012]

[Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings. FIG.
In the drawing, 1 is a cabinet body, 2 is a partition plate for dividing the internal volume of the cabinet body 1 into upper and lower parts, and 14 is a concave guide provided on the inner surface of the side wall of the cabinet body 1 corresponding to the opening of the partition plate 2. .

The partition plate 2 has a speaker unit 3 in advance.
Are fixed with screws 4 and nuts 5. Attach the partition plate 2 to the cabinet body 1
By simply inserting the partition plate 2 into the concave groove of the guide 14 mounted on the inner surface of the side wall of the guide plate 2 and pushing it in all the way, the mounting can be completed. This embodiment has a ratio of width to height of 1:
When applied to a small cabinet body having a width of 100 mm to 250 mm and having a width of 2 mm or more, the effect is great. However, even if it is used for other speaker cabinets, it can be easily mounted and workability is improved.

As shown in FIG . 2A , when the groove of the guide 14 is provided with an inclined portion 15 having a curvature, and the partition plate 2 is inserted, a stronger mounting can be achieved. (The dotted line in the figure is a line corresponding to the upper surface of the partition plate when the partition plate 2 is inserted. )

The specific dimensional relationship of this embodiment will be described. When the inclined portion 15 is formed by providing a curvature in the groove of the guide 14 as shown in FIG. 2A, the partition plate 2 is formed as shown in FIG. 2B . Is A, the size of the insertion opening of the guide 14 in the insertion direction of the partition plate 2 is B, and the size of the approximate center of the guide 14, which is the tip of the curvature, is C. At this time, B = A + α (α = 1 to 2 mm) and C = A− (1 ± 0.3 mm). If the material of the guide 14 is wood, C
Is smaller than A, the guide 14 is compressed at the time of insertion, and the repulsive force of the guide 14 applies a pressing force to a substantially central portion of the partition plate 2 to be fixed.

Embodiment 2 FIG. In the first embodiment, it is provided with the groove of the concave to guide 14, attached to the inner surface of the side wall of the cabinet main body 1 in cross-section two square bars with a predetermined spacing therebetween, the partition plate 2 at a portion spaced the distance May be inserted. Also in this case, it is needless to say that one or both of the rods are provided with an inclined portion so that the interval is reduced toward a substantially central portion in the insertion direction of the partition plate. In the first embodiment, the guide 14 has a concave groove, but the partition 2 has a concave groove.
The guide 14 may be engaged or fitted with a convex shape.

Embodiment 3 FIG. In the first embodiment, is provided with the inclined portion 15 in the groove of the guide 14, the inclined portion is not only the top of the groove as shown in Figure 2a,
It may be provided on the lower portion or on the side surface (inside of the groove). Further, an inclined portion 15 may be provided on the partition plate 2 side. Further, it may be provided on both the partition plate 2 and the guide 14 .

Embodiment 4 FIG. An elastic member having a smooth and resilient surface, such as a material such as foamed rubber, is attached to a portion of the partition plate 2 that comes into contact with the guide 14 so that the size of the central portion is maximized. You may comprise a part. The partition plate 2 is fixed by the restoring force of the elastic member compressed at the time of insertion.

[0019]

As described above, according to the present invention, a guide for inserting the partition plate is provided on the inner surface of the side wall of the cabinet body so that the partition plate is pushed in, and a portion where the guide contacts the partition plate is provided. In addition, an inclined part is provided so that the pressing force acts on almost the center of the partition plate, so that the assembling work is easy and the pressing force is applied to the entire partition plate, and the partition plate and the guide are firmly connected. And it can be stably mounted .
