本発明は、スピーカキヤビネツト本体の角度を
変えることなく、設置状態で簡単に指向角度を選
択することのできるスピーカキヤビネツトに関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker cabinet in which the directivity angle can be easily selected in the installed state without changing the angle of the speaker cabinet body.
従来のスピーカキヤビネツトは第１図Ａに示す
ように、低域再生用のキヤビネツト本体１に中域
再生ユニツト２及び高域再生ユニツト３を一体に
取り付けているため、指向角度を選択しようとす
る場合、キヤビネツト本体１の角度を変えねばな
らなかつた。 In a conventional speaker cabinet, as shown in Fig. 1A, a mid-range reproduction unit 2 and a high-frequency reproduction unit 3 are integrally attached to a cabinet body 1 for low-frequency reproduction, so it is difficult to select the directivity angle. In this case, the angle of the cabinet body 1 had to be changed.

し、第１図Ｂは指向方向が矢印ａ、矢印ｂと変化
する状況を示す側面図である。 For this purpose, additional processing such as angles, making the speaker stand or the cabinet body sloped, etc., were performed. 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. 1B is a side view showing a situation where the pointing direction changes from arrow a to arrow b.
しかし、このような構造ではコストの面や、コ
ンパクト性などに問題があつた。 However, such a structure has problems in terms of cost and compactness.

ようにしたものである。 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, which affect the directivity, are eccentrically centered from the center of the convex or concave buffle, without moving the main body of the cabinet. The pointing direction can be selected by attaching the unit to a certain position and rotating the entire unit.

It is rotatably attached to the cabinet body 1 for low frequency reproduction, and A 1 and A 2 are front and side views with the directivity angle upward, and B 1 and B 2 are with the directivity angle downward. Front view and side view of the case,
C 1 and C 2 show the front view and plan view when the directivity angle is the horizontal direction, and arrows a and b in figures A 2 , B 2 and C 2 are the direction of directivity, and figures A 1 , B 1 and C 1 arrow c
indicates the rotation direction of the convex buff 6.

ものである。 As described above, the present invention does not move the main body 1 of the cabinet, but rotates the convex or concave baffle that is integrally attached to the mid-range and high-frequency reproducing units that affect the directivity at eccentric positions from the center. By doing so, the directivity angle can be selected extremely freely, which is extremely effective in practice.
