Description

[Detailed Description of the Invention] The present invention relates to a wall body used as an inner wall of a conference room, a theater, etc.

Acoustics inside a large, enclosed building are generally difficult to hear due to the reverberating sound that hits the ceiling and walls.

For this reason, in order to obtain an appropriate amount of reverberation, the walls of the room are made of rectangular surfaces with protruding and recessed surfaces, such as square prism surfaces and square trowel surfaces, which are protruding and recessed, and these are repeatedly repeated on the uneven wall surface to transmit various sound waves. A method is used to prevent echoes by reflecting and diffusing them in different directions.

However, in this case, each reflective surface of these square uneven walls is flat, so the sound waves cannot be diffused sufficiently, and the fabrication is complicated, and installation work indoors is difficult. If it is desired to absorb all or part of the reflected sound waves, there are problems in that it is structurally difficult and difficult to change the design.

The purpose of this invention is to solve these problems mentioned above.It is very easy to manufacture, and it diffuses the sound without directing it, and it also allows adjustment of sound absorption and reflection. This makes it possible to obtain excellent acoustic effects.

That is, the wall body according to the present invention includes a plurality of rod-shaped bodies each having a dome-shaped cross section, which are arranged in parallel with each other at appropriate intervals, and the free edges of adjacent rod-shaped bodies are arranged at appropriate intervals in the longitudinal direction of the rod-shaped bodies. It consists of a panel connected by a connecting rod, and a sonicated wall located behind this panel and having a flat surface facing the concave surface of the rod-shaped body. The incident sound waves can be sufficiently diffused, and the sound waves that are incident on the side surface of the rod-shaped body can pass through the gap in the panel and be partially or completely absorbed or reflected by the sonic processing wall located behind the panel. Therefore, it is possible to obtain good acoustic effects that match the overall structure of the building and various sound sources.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In 1, the top 1a of the cross section is a circular arc, and both side surfaces 1b that follow it are wide or parallel, or have a so-called dome shape such as a parabolic line or a semicircle, and a plurality of rods are arranged in parallel at appropriate intervals. has been done.

Reference numeral 2 denotes a connecting rod which connects the side free end edges 1C of adjacent rod-like bodies 1 to each other at appropriate intervals in the longitudinal direction of the rod-like body 1.
A panel 3 is formed.

4 is a gap in the panel 3.

Reference numeral 5 denotes a sonic treatment wall provided at the rear of the panel 3, that is, on the side free end edge 1C of the rod-shaped body 1, and having a cloth 6 pasted on the front thereof, such as a sound-absorbing wall made of glass wool or a reflecting wall made of gypsum board. Alternatively, it may be a semi-acoustic wall made of perforated gypsum board with many holes vertically and horizontally.

This sonic treatment wall 5 includes a surface facing the concave surface of the rod-shaped body 1;
That is, the front surface is flat.

Next, the function of the wall according to the present invention will be explained.

In FIG. 2, sound waves A and B incident on the top 1a of the rod-shaped body 1 are reflected and diffused without having a fixed directionality.

The sound wave C hits the side surface 1b of the rod-shaped body 1 and is reflected, and then hits the side surface 1b of the adjacent rod-shaped body 1 and is reflected again, and then passes through the gap 4 of the panel 3.

If the sonicated wall 5 is a sound absorbing wall, the sound is absorbed as is.

After the sound wave hits the side surface 1b of the rod-shaped body 1 and is reflected, it passes through the gap 4 and is partially D1 if the sonic wave treatment wall 5 is a semi-sound absorbing wall.
is absorbed and remains D2, or if the sonic wave processing wall 5 is a reflective wall, the entire sound becomes D2 and is reflected on the wall surface, and further hits the side surface 1b of the adjacent rod-shaped body 1 and is diffused.

As explained above, according to the wall body according to the present invention, since the surface of the rod-shaped body is made into a convex curved surface with a dome-shaped cross section, sound waves can be sufficiently diffused, and the difficulty of hearing due to echo sound can be reduced. can be prevented.

In addition, since a gap is provided in the panel and a sonic wave treatment wall with a flat surface is provided on the back side of the panel, a sound absorption wall can be used as the sonic wave treatment wall to absorb the sound waves passing through the gap, or a reflective wall can be used. The sound can be set freely, such as by reflecting the sound or partially absorbing it by using a semi-absorbing wall. Therefore, it is possible to obtain a good acoustic effect that matches the overall structure of the building and various sound sources.

Furthermore, the panel is easy to manufacture and can be manufactured at low cost.
