ばならなかった。[Detailed Description of the Invention] The present invention allows the directivity angle to be easily selected in the installed state without changing the angle of the speaker cabinet body.
As shown in Figure 1), a conventional speaker cabinet has a mid-range reproduction unit 2 and a high-frequency reproduction unit 3 integrally attached to a cabinet body 1 for low-frequency reproduction. In order to select the directivity angle, the angle of the cabinet body 1 had to be changed.

が矢印ａ、矢印すと変化する状況を示す側面図である。To avoid this, additional processing was done to make the angle, the speaker stand, or the cabinet body slanted. The figure shows an example in which the cabinet main body 1 is swingably supported by the support arm 5 of the speaker stand 4, and FIG. 1(B) is a side view showing a situation where the orientation direction changes as the direction of the speaker stand 4 changes as shown by the arrow a.

したものである。In order to solve the above-mentioned problems, the present invention has developed a system in which the mid-range and high-range reproduction units that affect the directivity are installed in a convex "puff" or a concave "puff" shape without moving the cabinet body. The direction of pointing can be selected by rotating the baffle that is attached and integrated.

回転方向を示す。FIG. 2 shows an embodiment of the present invention in which a convex baffle is used.
It is rotatably attached to the cabinet main body 1 for low frequency reproduction, (A1) and (A2) are front and side views when the directivity angle is upward, (B1) and (B2)
are a front view and a side view when the directivity angle is downward, (C

Arrows a and b in (C2) and (C2) are directional directions, Figure (A,)
The arrow C in (B,) and (C1) indicates the direction of rotation of the convex panfluro.

This is the same as explained in the figure.
以上述べたように、本発明はキャビネット本体１を動か
