A front decorative plate 9 that is convexly curved forward and substantially the same width, a vertical picture frame 10 that engages the side end portions of both the back plate 8 and the front decorative plate 9, the upper end of the back plate 8 and the front decorative plate 9, and The top plate 11 and the bottom plate 12 are respectively engaged with the lower ends. Although not shown in FIG. 1, the front decorative plate 9 is provided with a communication portion 13 that communicates with the inside of the acoustic panel 2, and a sound adjustment plate 14 made of an insulation board is provided inside the acoustic panel 2. It is sandwiched between the back plate 8 and the side end portion of the front decorative plate 9 and is provided along the back plate 8. Further, a horizontal beam 19, which is a substantially D-shaped plate having a curved front surface, which is in contact with the front decorative plate 9 at the front end surface and in contact with the back plate 8 at the rear end surface, is interposed between the top plate 11 and the bottom plate 12. Provided.

又、前化粧板９が横方向に一定間隔をあけ並設される複数枚の帯板状の前板１３ａで構成され、連通部１３を帯板間の隙間部分としており、前化粧板９を構成する前板１３ａ間の隙間部分後方に、帯板状の後板１３ｂを設けている。更に、横桟１９の前面部分を櫛歯状に形成し、櫛歯状部分の凸部先端に前板１３ａを、凹部後端１１に後板１３ｂをそれぞれ設けている。   Further, the front decorative plate 9 is composed of a plurality of strip-shaped front plates 13a arranged side by side in the horizontal direction, and the communication portion 13 is a gap portion between the strips. A belt-like rear plate 13b is provided behind the gap between the front plates 13a. Further, the front portion of the cross rail 19 is formed in a comb-like shape, and a front plate 13a is provided at the front end of the convex portion of the comb-like portion, and a rear plate 13b is provided at the rear end 11 of the concave portion.

この音響パネル２の素材はそれぞれ、前板１３ａ及び後板１３ｂは、インテリアとしても音響拡散パネル装置を用いることを考え、ムクのシナ材を用いている。そして縦額縁１０及び天板１１、底板１２はアスペン材を用いている。なお、これら以外にも種々の木材、金属、樹脂板などを用いることが可能である。   As for the material of the acoustic panel 2, the front plate 13a and the rear plate 13b are made of mulberry Chinese material considering that the acoustic diffusion panel device is used as the interior. The vertical frame 10, the top plate 11, and the bottom plate 12 use aspen material. In addition to these, various woods, metals, resin plates, and the like can be used.

又、支持脚１を支える支持板１５は板状であるが、音響パネル２が図７（ｃ）に示す如く、その重心が前方に偏ったときにそれを支えるため、前方に突出した突出部１５ａが設けられている。この場合、支持板１５の両末端に突出部１５ａを設け、全体として前方に開口したＵ字状となっている。又、この場合、支持脚１は支持板１５の上方に設けられた横長棒状の固定片１６を介して固定されている。   Although the support plate 15 for supporting the support leg 1 is plate-shaped, as shown in FIG. 7 (c), the acoustic panel 2 supports it when its center of gravity is biased forward. 15a is provided. In this case, projecting portions 15a are provided at both ends of the support plate 15, and the U-shape is opened forward as a whole. In this case, the support leg 1 is fixed via a horizontally long bar-shaped fixing piece 16 provided above the support plate 15.

又、音響パネル２の背面７の下端部には、平面視略コ字型の板状で、背面７に対して開口した断面コ字型の音響パネル２を支持脚１に補助的に固定するための支持脚係合部１８が設けられている。このコ字型の開口の幅は、支持脚１が音響パネル２に対して水平方向にスライドするため、支持脚１がスライドする範囲に合わせて設定されている。   In addition, an acoustic panel 2 having a substantially U-shaped plate shape in plan view and opened to the rear surface 7 is supplementarily fixed to the support leg 1 at the lower end of the rear surface 7 of the acoustic panel 2. A support leg engaging portion 18 is provided. The width of the U-shaped opening is set in accordance with the range in which the support leg 1 slides because the support leg 1 slides in the horizontal direction with respect to the acoustic panel 2.

なお、この音響拡散パネル装置は、単独で部屋の隅部やスピーカーなどの音響機器に隣接して設置することもできるが、複数の音響拡散パネル装置を水平方向に屏風のようにならべて用いることもできる。   In addition, although this acoustic diffusion panel apparatus can be installed adjacent to acoustic equipment such as a corner of a room or a speaker alone, a plurality of acoustic diffusion panel apparatuses should be used in a horizontal direction like a folding screen. You can also.

従って、この実施形態の音響拡散パネル装置においては、各々の音響パネル２が水平方向に滑動するスライド機構４を介して支持脚１に係合支持されると共に各々の支持脚１に音響パネル２を水平方向に回動させる回動機構５を設けているため、図６に示す如く、支持脚１の間隔を一定に固定したまま、音響パネル２を屏風のように折りたたみできる。又、それにより、音響パネル２をスムーズに開閉できる。   Therefore, in the acoustic diffusion panel device of this embodiment, each acoustic panel 2 is engaged and supported by the support leg 1 via the slide mechanism 4 that slides in the horizontal direction, and the acoustic panel 2 is attached to each support leg 1. Since the rotation mechanism 5 that rotates in the horizontal direction is provided, the acoustic panel 2 can be folded like a folding screen while the interval between the support legs 1 is fixed, as shown in FIG. Thereby, the acoustic panel 2 can be opened and closed smoothly.

又、音響パネル２の前面に音を反射し吸収する作用面６が形成されており、音響パネル２がその背面７で支持脚１に支持されているため、音響パネル２を屏風のように開閉させることで、音を吸収させる範囲、反射させる方向を微調整できる。従って、家庭の居室空間においては、音が集中、乱反射しやすく音環境の悪化を引き起こす原因となる隅部に設置することで居室空間の音環境を良好なものとすることができ、又、スピーカーなどの音響機器の背面に設置することで、音響機器からの発せられる音を視聴者に向かって程よく反射させることができる。   Moreover, since the action surface 6 which reflects and absorbs a sound is formed in the front surface of the acoustic panel 2, and the acoustic panel 2 is supported by the support leg 1 on the back surface 7, the acoustic panel 2 is opened and closed like a folding screen. By doing so, the range in which sound is absorbed and the direction in which it is reflected can be finely adjusted. Therefore, in the living room space at home, the sound environment of the living room space can be improved by installing it at the corners where the sound tends to concentrate and diffusely reflect and cause the deterioration of the sound environment. The sound emitted from the acoustic device can be appropriately reflected toward the viewer.

更に、音響パネル２が背面７で支持脚１に支持されているため、支持脚１やスライド機構４などが前面から見えなくなるために見栄えがよくなる。そして、スライド機構４や回動機構５が音響パネル２の外部に露出しているため、壁に直接固定するように設計・製造した一般的な壁パネルを用いて製造することもでき、別途音響パネル２を設計・製造する必要がない。それに加えて、仮にスライド機構４や回動機構５が故障してしまっても、修理しやすく、メンテナンスも容易である。   Furthermore, since the acoustic panel 2 is supported by the support leg 1 on the back surface 7, the support leg 1, the slide mechanism 4 and the like cannot be seen from the front surface, so that the appearance is improved. Since the slide mechanism 4 and the rotation mechanism 5 are exposed to the outside of the acoustic panel 2, it can be manufactured using a general wall panel designed and manufactured to be directly fixed to the wall. There is no need to design and manufacture the panel 2. In addition, even if the slide mechanism 4 or the rotation mechanism 5 breaks down, it is easy to repair and maintenance is easy.

又、音響パネル２が、前方に凸に湾曲した前化粧板９を備えているため、音を一定方向に反射させるのではなく、ある程度の範囲に拡散させることができる。更に、前化粧板９に連通部１３が設けられているので、音をすべて反射させるのではなく、一部吸収させることができる。それに加え、背板８と音調整板１４をインシュレーションボードで構成し、沿設しているため、インシュレーションボードの吸音効果を高めることができる。   In addition, since the acoustic panel 2 includes the front decorative plate 9 that is convexly curved forward, the sound can be diffused in a certain range rather than reflecting in a certain direction. Furthermore, since the communication part 13 is provided in the front decorative board 9, not all the sounds can be reflected, but a part can be absorbed. In addition, since the back plate 8 and the sound adjustment plate 14 are constituted by an insulation board and are installed side by side, the sound absorption effect of the insulation board can be enhanced.

又、支持板１５に前方に突出部１５ａを設けているため、音響パネル２の開閉により重心が前方に偏っても、本願発明の音響拡散パネル装置は転倒しにくい。更にこの場合、突出部１５ａを支持板１５の両端に設けているためにより転倒しにくくなり、又、支持板１５を板状としているため軽量化が図れる。   Moreover, since the protrusion 15a is provided on the support plate 15 forward, even if the center of gravity is biased forward due to the opening and closing of the acoustic panel 2, the acoustic diffusion panel device of the present invention does not easily fall over. Further, in this case, since the protrusions 15a are provided at both ends of the support plate 15, it is difficult to fall down, and the support plate 15 has a plate shape, so that the weight can be reduced.

又、本願発明の音響拡散パネル装置は、１つを単独で使うだけでなく、複数の音響拡散パネル装置を屏風状に並べて使用することもでき、これにより、音を吸収、反射させたい範囲を変化させることができる。従って、ホームシアターなどの個人の居室空間からホール等の大型施設まで、様々な場面での音環境の微調整が行える。   In addition, the acoustic diffusion panel device of the present invention can be used not only by itself but also by arranging a plurality of acoustic diffusion panel devices in a folding screen, so that the range in which sound is desired to be absorbed and reflected can be obtained. Can be changed. Accordingly, it is possible to finely adjust the sound environment in various scenes from a private room space such as a home theater to a large facility such as a hall.
