Description

[Detailed Description of the Invention] This invention relates to a box speaker device incorporating a backroad horn.

Generally, in concert venues, relatively large box speakers for the audience seats and relatively small box speakers for the stage are often used in combination, but in the past, such speakers were used separately, one at a time. It is normal to pack, store and transport.
The problem was that it required a lot of space and packaging materials for storage and transportation, resulting in high costs.

This invention was devised in view of the above-mentioned drawbacks of the conventional art, and will be described in detail below based on embodiments shown in the drawings. As shown in FIG. 1, the speaker device includes a bass speaker 2 built into a front panel 1, and a cross-sectional area gradually increasing between a rear panel 4 and a bottom panel 5 by a partition plate 3 in an internal space. A relatively large first speaker box 7 in which a Claude horn 6 is formed, and a front plate formed in the back Claude horn 6 to a size that can be stored and drawn out from the front opening and inclined along the partition plate 3. a relatively small second speaker box 10 in which a speaker 9 is built into the speaker box 8;
It is equipped with

As shown in FIG. 2, a pair of guide rails 12 are provided on the inner wall of the bottom plate 5 of the first speaker box 7 to match the width of the rear plate 11 of the second speaker box 10. A pair of connectors 13 made of a magnet and an iron plate or a tape-shaped fastener are provided at corresponding positions on the lower surface of the speaker box 3 and the four corners of the front plate of the second speaker box 10.
Note that support legs 15 and 16 are attached to the bottom plates 5 and 14 of the speaker boxes 7 and 10, respectively.

With this configuration, the second speaker is placed inside the backroad horn 6 of the first speaker box 7.
By accommodating, packing, storing, and transporting the second speaker box 10, the packaging materials and space for the second speaker box 10 are omitted, and the cost required for these is reduced. In addition, the operation of storing and pulling out the second speaker box 10 is carried out smoothly along the guide rail 12 which also serves as reinforcement for the bottom plate 5, and the stored state is maintained by the connector 13, so that the second speaker box 10 can be stored and pulled out smoothly during transportation. This prevents the second speaker box 10 from coming off and shaking.

As mentioned above, according to this invention, a small speaker box can be housed inside the back load horn, so it is possible to save packaging materials and space for storage and transportation, especially when moving from place to place. This has the practical effect of being able to provide a speaker device suitable for use at a low cost.
