が得られるようにしたものである。[Detailed Description of the Invention] The present invention relates to a multi-way speaker system, in which characteristics suitable for the installation conditions of the speaker system can be obtained by easily changing the position of speakers for middle and high ranges, which have strong directivity. It is something.

問題がある。In the conventional multi-way speaker system, as shown in FIG. 1, a woofer 3, squawker 4, and tweeter 6 are simply fixedly attached to a baffle plate 2 on the front side of a speaker box 1 in a line. For this reason, if the speaker box 1 is installed in a horizontal position as shown in FIG. 2, depending on the space of the room, the installation position of the speaker box, etc., there is a problem in that the directivity of the squawker 4 and tweeter 6 impairs the reproduction characteristics.
本発明はこのような問題が簡単に解決できるようにしだ
スピーカシステムを提供するものである。The present invention provides a speaker system that can easily solve these problems.
以下本発明の一実施例を第3図〜第6図とともに説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.
第3図〜第6図において、実質的に第1図、第2図と同

形の取付孔2aに回転自在に取付けられている。In FIGS. 3 to 6, parts having substantially the same functions as those in FIGS. 1 and 2 are designated by the same reference numerals, and explanations thereof will be omitted. 6 is a circular sub-baffle plate, and the squawker 4 and tweeter 6 are attached to this sub-baffle plate 6. The sub-baffle plate 6 is rotatably attached to a circular attachment hole 2a provided in the baffle plate 2.

合には、サブバッフル板6を所定角度回転させるだけで
、再生特性を改善することができる。Therefore, if the arrangement is as shown in FIG. 3, the speaker arrangement will be the same as in FIG. 1. Further, as shown in FIG. 4, by rotating the sub-baffle plate 6 by several degrees, the direction in which the squawker 4 and the tweeter 6 are arranged can be made orthogonal to the longitudinal direction of the speaker box 1. Of course, since the sub-baffle plate C can be fixed at any rotation angle, the direction in which the squawker 4 and tweeter 6 are arranged can also be set at any angle. Therefore, if the reproduction characteristics deteriorate due to the installation state of the support peaker box 1, the reproduction characteristics can be improved simply by rotating the sub-baffle plate 6 by a predetermined angle.

り指向性が変化することがわかる。Figure 6 shows the sound pressure-frequency characteristics of Figures 1 to 4, where A is the characteristic on the radiation axis of the speaker system of Figures 1 and 3, and B is the characteristic of the speaker system of Figure 2. C is the characteristic at an angle of 60° from the radial axis of the system; C is the characteristic at an angle of 600° from the radial axis of the loudspeaker system of FIG. Above B
', , C, it can be seen that the directivity changes by rotating the sub-baffle plate e and changing the positions of the squawker 4 and the tweeter 6.

るなどすればよい。In order to rotatably mount the sub-baffle plate 6, for example, countersinks are provided in opposite directions on the outer periphery of the sub-baffle plate 6 and the inner periphery of the mounting hole 2a of the baffle plate 2, and these are then slid. They may be engaged freely, and the sub-baffle plate 6 may be prevented from slipping back and forth using well-known means.

特性が簡単に得られるという優れた効果が得られる。As described above, in the present invention, a plurality of speakers for medium and high ranges with strong directivity are attached to a sub-baffle plate, and this sub-baffle plate is rotatably attached to the baffle plate of a speaker box, so that the speaker system can be easily installed. An excellent effect can be obtained in that characteristics matching the conditions can be easily obtained.
