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. This is what I did.

問題がある。 Conventional multi-way speaker systems
As shown in the figure, a woofer 3, a squawker 4, and a tweeter 5 are simply fixedly attached to a baffle plate 2 on the front side of a speaker box 1 in a line. Therefore, depending on the space of the room and the installation position of the speaker box, if the speaker box 1 is installed horizontally as shown in Figure 2, there is a problem that the playback characteristics will be impaired due to the directivity of the squawker 4 and tweeter 5. be.
本発明はこのような問題が簡単に解決できるよ
うにした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 in which such problems can be easily solved.
以下本発明の一実施例を第３図〜第５図ととも

ａに回転自在に取付けられている。 In FIGS. 3 to 5, parts having substantially the same functions as those in FIGS. 1 and 2 are denoted by the same reference numerals, and explanations thereof will be omitted. Reference numeral 6 denotes a circular sub-buff full plate, and a squawker 4 and a tweeter 5 are attached to this sub-buff full plate 6. The sub-buff full plate 6 has a circular mounting hole 2 provided in the buff full plate 2.
It is rotatably attached to a.

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. Also, as shown in Figure 4,
By rotating the sub-buff full plate 6 by 90 degrees, the squawker 4 and tweeter 5 can be arranged in the same direction as the speaker box 1.
It can be perpendicular to the longitudinal direction of. Of course, since the sub-buff full plate 6 can be fixed at any rotation angle, the direction in which the squawker 4 and tweeter 5 are arranged can also be set at any angle. Therefore, if the reproduction characteristics deteriorate due to the installation condition of the speaker box 1, the reproduction characteristics can be improved simply by rotating the sub-buffle plate 6 by a predetermined angle.

が変化することがわかる。 Figure 5 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. Characteristics at an angle of 60° from the radial axis of the system,
C is the characteristic of the speaker system of FIG. 4 at an angle of 60° from the radiation axis. As is clear from the above B and C, it can be seen that the directivity changes by rotating the sub-buffer plate 6 and changing the positions of the squawker 4 and tweeter 5.
