を得ない。Speaker boxes that are currently in general use are constructed in a rectangular parallelepiped shape by combining multiple flat plates and bonding them together with adhesive, etc. However, when considering the generation of standing waves inside the box, the shape cannot be changed. The structure becomes complicated due to the addition of three-dimensional shapes, and the manufacturing cost inevitably increases significantly.

複雑にならざるを得ない。Further, as shown in FIG. 1, a speaker box 3 in a two-way speaker system including a speaker unit 1 for a low frequency range and a speaker unit 2 for a medium and high frequency range includes a power box 3 from each speaker unit 1, 2. A so-called back chamber is installed inside the main box 3a in order to prevent the acoustic outputs radiated inside from interfering with each other and to provide a speaker box with an appropriate volume for the speaker unit 2 for medium and high frequency ranges. A sub box 3b is arranged. The structure of the main box 3a and sub-box 3b also becomes complicated if consideration is given to preventing the above-mentioned standing waves from occurring.

18 is a sub-box main body forming a so-called back chamber within the main box 16. As shown in FIGS. 3A to 3C, the sub-box main body 18 has a hollow cylindrical body 21 which is closed by side plates 19 and 20 having both ends 21A and 21B fixed with adhesive, respectively, in the cylindrical direction. It is cut at an appropriate slope.

ャンバーを形成している。That is, FIG. 3A shows an external perspective view of the hollow cylindrical body 21, which is made by cutting a vibrator-like material such as paper, vinyl chloride, plastic, or metal into an appropriate length. It consists of FIG. 3B shows that both ends 21A, 21B of the hollow cylindrical body 21 are connected to the side plates 19, 20.
Each side plate 19, 20 has grooves 19a, 20 into which the ends 21A, 21B are fitted.
b is engraved, and both ends 21A, 21B of the hollow cylindrical body 21 are closed and fixed to the grooves 19a, 20b with an adhesive. And each side plate 1 mentioned above
The hollow cylindrical body 21 with both ends 21A and 21B closed by 9 and 20 is cut at an appropriate inclination in the cylindrical direction (third
The cut plane 22 is indicated by a dashed-dotted line in FIG. ), two sub-box counters 18 having a shape as shown in FIG. 3C are formed at a time. The sub-box main body 18 as shown in FIG. 3C is adhesively fixed to the speaker mounting plate 11 so that its cut surface 22 surrounds the opening 15, as shown in FIG. It forms a back chamber.

It has a hollow scalene three-dimensional shape, and since each of the side plates 19 and 20 is inclined with respect to the radiation axis of the acoustic output from the speaker unit 13, it is possible to prevent the generation of standing waves inside the side plates 19 and 20. It has become extremely rare.

Moreover, the above-mentioned back chamber bar can be easily formed.According to the present invention, the sub-box main body is formed by cutting a hollow cylindrical body with both ends closed at an angle in the cylindrical direction. Since the speaker mounting plate is attached to cover the speaker unit for high-frequency sound reproduction, the sub-box body can effectively prevent the generation of standing waves in the so-called back chamber, which has a scalene three-dimensional shape. A speaker system that is easy to manufacture and low cost can be provided.
