Description

[Detailed Description of the Invention] The present invention relates to an improvement of a speaker cabinet, particularly a speaker cabinet made of particle board.

Generally speaking, a speaker cabinet is known to have a speaker unit built into the cabinet body, and to improve acoustic effects.

FIGS. 1 and 2 show a perspective view and a vertical sectional view, respectively, of such a conventional speaker cabinet.

The cabinet body 10 is made of particle board in a box shape, and a baffle plate 12 made of the same material as the cabinet body 10 is provided on the front surface.

An end portion of a protective net 14 is fixed around the baffle plate 12, and this protective net 14 is attached to the baffle plate 12.
The front surface of the speaker unit 16 is covered to protect the speaker unit 16 from dust entering from the outside and from breaking the cone of the speaker unit 16, which will be described later.

This protective net 14 is made of thin cloth so as not to impair the acoustic effect.

A crosspiece 18 is provided between the baffle plate 12 and the protective net 14, and maintains a constant distance between these end portions 12 and 14.

The baffle plate 12 to which the protective net 14 is fixed is fixed to the cabinet body 10 with wood screws 20.

Further, a circular hole 12a is provided at an appropriate position on the baffle plate 12, and a speaker unit 16 having a diameter larger than the hole 12a is attached to the back edge of the hole 12a.

When attaching the speaker unit 16 to the baffle plate 12 in this way, since the baffle plate 12 is made of paratiful hoard as described above, particles of the particle board will pass through the holes 12a to the baffle plate 12 and the protective net. It falls between 14 and 14.

Since the conventional speaker cabinet has the above-mentioned configuration, the particles that have entered through the holes 12a are scattered on the surface of the baffle plate 12, which is painted black, and these particles are
It is a white color that stands out against the black surface of the speaker cabinet 2, and is visible through the thin cloth protective net 14, which has the disadvantage of detracting from the aesthetic appearance of the speaker cabinet.

Also, while transporting the speaker cabinet,
Because particles are generated by applying external vibration,
The result was the same as above, and there was a drawback that the aesthetic appearance was impaired.

Therefore, there has been a demand for the production of speaker cabinets 1 to 1 that do not impair the aesthetic appearance even when debris is generated.

The present invention was created in view of such conventional problems,
The purpose is to provide a speaker cabinet that does not affect the acoustic effect, which is the essential function of the speaker cabinet, and does not impair the aesthetic appearance.

In order to achieve the above object, the present invention provides a baffle plate that is fixed to the cabinet body and has a speaker unit attached thereto, a protective net that is fixed to the baffle plate and protects the speaker unit, and a protective net that is installed between the baffle plate and the protective net. and a crosspiece for maintaining a constant distance between the two members, characterized in that a recessed chip storage portion is provided at a joint between the baffle plate and the crosspiece.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

3 to 5 show preferred embodiments of the speaker cabinet according to the present invention, respectively.

In each figure, the same members as those in the conventional example described above are given the same reference numerals, and their explanations will be omitted.

In the first embodiment shown in FIG.
A concave-shaped particle storage section 22 is provided on the side of the crosspiece 18 at the joint between the board and the crosspiece 18, and the particle board particles that enter through the cutout hole 12a are stored in the storage section 22. , it is no longer visible through the thin protective net 14.

Further, particles generated during transportation are similarly stored in the particle storage section 22.

In the first embodiment, adhesive 2 is attached to the bottom surface of the particle storage section 22.
4 is attached, and the particles stored in the storage section 22 are adhesively captured by the adhesive 24, and once stored, the particles will not come out of the particle storage section 22 again. Therefore, it is more effective.

In the second embodiment shown in FIG. 4, not only the crosspiece 18 but also the baffle plate 12 are provided with a recessed chip storage section 22 at a position lower than the bottom surface of the crosspiece 18, and the bottom surface of the storage section 22 As in the first embodiment, an adhesive 24 is attached to the shavings, and since the particles are adhesively captured by the adhesive 24, they become even more difficult to see from the outside.

In the third embodiment shown in FIG.
A concave-shaped particle storage portion 22 is provided only in 1.
Since the particles stored in the storage portion 22 are difficult to come out, even if the adhesive 24 is not applied, the particles stored in the storage portion 22 are
It is possible to obtain the same effects as in the embodiment.

As explained above, according to the present invention, by providing the concave-shaped particle storage section at the joint between the baffle plate and the crosspiece, the aesthetic appearance of the speaker cabinet is spoiled without affecting the acoustic effect of the speaker. It has the advantage of not having

[Brief explanation of drawings]

Fig. 1 is a perspective view of a conventional speaker cabinet, Fig. 2 is a vertical sectional view of the conventional example shown in Fig. 1, and Figs. It is a diagram. In each figure, the same members are given the same reference numerals, and 10 is the cabinet body, 12 is a baffle plate, 14 is a protective net, 18 is a crosspiece, 22 is a particle storage section, and 24 is an adhesive.

Claims (2)

[Scope of utility model registration request] (1) A baffle plate that is fixed to the cabinet body and has a speaker unit attached to it, a protective net that is fixed to the baffle plate and protects the speaker unit, and a protective net that is installed between the baffle plate and the protective net to maintain a constant spacing between both members. What is claimed is: 1. A speaker cabinet having a crosspiece, characterized in that a concave chip storage section is provided at a joint between the baffle plate and the crosspiece.
