Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement in the interior structure of a studio, music hall, audio room, listening room, etc., for adjusting the reflection of sound on the walls and ceiling surfaces.

(Conventional configuration and its problems) Traditionally, in rooms where the above acoustic effects are required, in order to reduce the volume difference in all parts of the room and prevent mutual interference between speakers, In some cases, some interior walls and ceilings are formed into chevron-shaped uneven surfaces, but in order to create such an uneven surface, decorative boards such as plywood must be used while taking sound reflection into consideration. It is necessary to adjust the angle of each decorative board and install it individually, which takes time and effort, and because the butt parts of each decorative board are joined at an angle, gaps are likely to occur, so avoid There was a problem that the sound quality was lower than that of other finished surfaces.

(Purpose of the invention) The present invention aims to eliminate the above-mentioned problems. It adjusts the reflections on the walls and ceiling surfaces in rooms such as audio rooms, and prevents the transmission of sound into adjacent rooms, thereby improving the acoustic adjustment effect and improving the sound quality. To provide an interior structure for an audio room or the like that can efficiently form an interior surface with excellent sound insulation properties in a short time.

(Structure of the invention) In order to achieve the above object, the interior structure of the invention has an appropriate shape such as a V-shape or a U-shape that reaches the soft sound-insulating sheet on the surface of the decorative material made of a wooden board or the like lined with a soft sound-insulating sheet. A plurality of shaped bending grooves are cut in parallel, and the decorative board is bent in an appropriate zigzag shape through these bending grooves, and is placed and fixed from the base of the wall or ceiling through air spaces at appropriate intervals. This allows the direction of sound reflection in rooms such as audio rooms to be adjusted by the bending angle of the decorative material, and the sound transmitted from the bent portion of the decorative material is blocked by the sound insulating sheet lining to prevent sound from leaking into adjacent rooms. It is configured so that it can be obtained.

(Explanation of Examples) Figure 1 shows an example of decorative materials used for interior structures, and 1 is a large rectangular decorative material made of decorative plywood, calcium silicate board, fiberboard, and other architectural boards. A soft sound insulating sheet 2 such as a synthetic resin sheet or a rubber sheet mixed with metal powder, inorganic powder, etc. is adhered to the entire back surface thereof.

3, 3, ... 3 are bent grooves with a V-shaped or U-shaped cross section carved across the entire width or length in the width direction or length direction, and have a depth that reaches the soft sound insulating sheet 2. There are multiple bending grooves 3 at predetermined intervals.
The decorative material 1 is formed into a plurality of rectangular decorative board pieces 1a that are arranged in parallel.

4 is a nonwoven fabric polymerized and bonded to the back surface of the soft sound insulating sheet 2, which reinforces the bent portions of the soft sound insulating sheet 2 to prevent tearing at the bent portions, and improves the adhesion function to the mounting frame described later.

Note that the soft sound insulating sheet 2 preferably has a weight of 2.0 kg/m ² or more in order to prevent sound from passing through the folded portion.

FIG. 2 shows another embodiment of the present invention, in which a plurality of bending grooves 2 as described above are provided in the decorative material 1 vertically and horizontally. It is possible to bend in a zigzag pattern both horizontally and horizontally, and if the grooves are provided at narrow intervals of about 5 cm, the bending position can be freely selected.

The interior decoration material constructed in this way is folded into a zigzag shape by folding each decorative board piece 1a through the bending groove 3 into a zigzag shape so as to form an inclined surface of an appropriate angle, and then As shown in the figure, it is fixed to a base 5, such as a wall, with an appropriate space from the surface of the base to form an interior surface.

Reference numeral 6 denotes an air layer provided between the base 5 and the decorative material 1.

As a means for fixing the decorative material 1 to the base 5,
For example, as shown in FIG. 3, a crosspiece 7 that supports the bent portion of the mountain fold of the decorative material 1 is framed in front of the base 5, and this crosspiece 7 is attached with adhesive or a combination of adhesive and nails. Installed. Further, the bent portion of the decorative material 1 at the valley fold portion may be attached to the crosspiece 8 fixed to the base 5.

Although the thickness of the air layer 6 is not particularly limited, it is desirable to provide the air layer 6 approximately 5 to 30 cm behind the convex fold protrusion of the decorative material 1.

(Effect of the invention) As described above, according to the interior structure of an audio room or the like of the present invention, the surface of the decorative material 1 made of a wooden board or the like lined with the soft sound insulation sheet 2 has a V-shaped or Since a plurality of U-shaped bending grooves 3 are carved in parallel, the decorative material 1 can be folded into a mountain or valley at a desired bending angle through the bending grooves 3, and the inclination angle can be adjusted. It can be set freely, optimally disperses sound reflections, reduces differences in volume at all locations in the room, and produces acoustic effects that are easy to hear.
Furthermore, since the soft sound insulating sheet 2 is continuously attached to the back surface of the decorative material 1, it reliably prevents sound from passing through the bent portions and provides an excellent sound insulating effect. Since the decorative material 1 is stretched from the wall base etc. through an air layer 6 in the space as appropriate, the air layer 6 provides a damping effect for low-frequency sounds that pass through the decorative material 1 and the sound insulation sheet 2. The decorative material 1 resonates by reverberating the frequency sound, exhibiting a sound absorption effect, and can reduce unpleasant low-frequency sounds.

Furthermore, since the decorative material 1 can be installed by simply bending it, there is no need to adjust the angles of the individual decorative boards and attach them one by one, as is the case in the past, and the work can be carried out efficiently.
