However, when a wallpaper having fine holes is used, the clogging of the holes is apt to occur due to the adhesion of the adhesive at the time of adhesion, and the clogging of the holes causes the ventilation of the wallpaper. There is a problem in that the sound absorption effect is impaired due to the impaired performance. In addition, when using wallpaper without backing paper, you can not use non-breathable materials such as vinyl wallpaper and inorganic wallpaper, only woven wallpaper can be used, and there are many types of wallpaper currently on the market. I couldn't use the wallpaper. Furthermore, since the types of wallpaper are limited, there is a problem in that it is difficult to match the texture and color feeling with general wallpapers that are adhered to walls that do not require sound absorption effects. In other words, the wallpaper that is attached to the wall that does not require sound absorption effect is not particularly limited in material, so you can use the wallpaper according to your preference from a wide variety of wallpapers, but in the case of woven wallpaper, the texture As a result, there is a problem in that it is difficult to harmonize the texture and the color sense between the makeup acoustic sound absorbing plate and another wall because the color sense is limited. Such a problem also occurs when a breathable cloth or net is used.

The present invention has been made in order to solve the above problems, and there is no particular limitation on the material, and a method for producing a cosmetic acoustic sound absorbing plate which is easy to harmonize the texture and color feeling with other walls. Is intended to provide.

According to the method of manufacturing a sound-acoustic sound absorption board of claim 1, in order to manufacture a sound-acoustic sound absorption board by adhering a wallpaper as an interior finishing material to the surface of a base material having a sound absorbing member, After adhering the wallpaper to at least the surface of the base material, ventilation holes are formed from the surface of the wallpaper to at least the sound absorbing member.

According to a second aspect of the present invention, there is provided a method of manufacturing a cosmetic sound absorbing board according to the first aspect, wherein the opening ratio of the ventilation holes is different depending on the location of one cosmetic sound absorbing board. is there.

[0007]

According to the above-mentioned means, since the ventilation hole is formed in the wallpaper after the wallpaper is adhered to the sound absorbing member, the clogging problem due to the adhesive does not occur at all, so that the ventilation property of the wallpaper is secured. It Therefore, if this cosmetic sound absorbing board is installed and played in a place with excessive reverberation where sound effects are generally poor such as in a multipurpose hall or gymnasium, the sound produced by the sound absorbing acoustic board is effective. It can absorb sound and improve the state of hyperreverberation. Further, since the material used as the wallpaper is not limited, it is possible to select a wallpaper according to the taste from various wallpapers, and it becomes easy to take harmony with other walls and ceilings.

EXAMPLES Examples of a method for manufacturing a decorative acoustic sound absorbing plate according to the present invention will be described below.

FIG. 1 is an external view of a decorative acoustic sound absorbing plate manufactured by the method of the embodiment as seen obliquely from the front, and FIG. 2 is a plan view of the decorative acoustic sound absorbing plate. .
Reference numeral 1 denotes a makeup sound absorbing plate, and this makeup sound absorbing plate 1 is an interior finishing material that covers the plate-shaped base material 2 and the surface and side surfaces of the base material 2 so as to embrace them. It is composed of a certain wallpaper 3. Further, the wallpaper 3 of the decorative acoustic sound absorbing plate 1 is formed with a vent hole 5 reaching the inside of the sound absorbing member.

Here, the base material 2 is composed of a sound absorbing member such as rock wool board, glass wool board or foam board. In this case, the base material 2 may be composed of only the sound absorbing member or may partially include the sound absorbing member. Further, the sound absorbing member may be composed of a single member, or may be composed of different members laminated. As the wallpaper 3, one selected from a wide variety of wallpapers currently on the market according to taste is used. The diameter of the vent hole 5 is, for example, 1
The density is less than about mm, and the formation density of the ventilation holes 5 is, for example, about several tens / cm ² . This ventilation hole 5
Is formed by a multi-needle pusher.

The makeup sound absorbing plate 1 thus constructed is used by being installed on the ceiling or wall of a gymnasium or a multipurpose hall.

Next, the method of manufacturing the decorative acoustic sound absorbing plate 1 will be described. First, after the wallpaper 3 which is an interior finishing material is adhered to the surface of the base material 2, the fine ventilation holes 5 are formed from the surface. Open. The ventilation hole 5 penetrates the wallpaper 3 and is opened to reach the inside of the sound absorbing member. As a result, the cosmetic sound absorbing member 1 is obtained. The ventilation holes 5 opened at this time may be formed before installation as a ceiling or a wall, or may be formed after installation.

The cosmetic sound absorbing member 1 thus configured
According to this, the following effects can be obtained.

According to the cosmetic sound absorbing member 1 of this embodiment, since the ventilation holes 5 formed in the wallpaper 3 are formed by retrofitting and reach the inside of the sound absorbing member, the air permeability (sound permeability) is excellent, The sound wave that has passed through the ventilation hole 5 reaches the sound absorbing member, a part of the energy thereof is changed to heat energy, and the energy of the sound wave is apparently lost. Therefore, if the cosmetic sound absorbing board 1 is installed and played in a place where the sound effect is generally bad and the sound is excessively reverberant, such as a multipurpose hall or a gymnasium, the sound of the performance is reproduced.
Can effectively absorb sound and improve the state of excessive reverberation.

Further, since the ventilation holes 5 are formed by retrofitting, it is possible to appropriately change the number of the ventilation holes 5 in one makeup acoustic sound absorbing plate 1 depending on the location, and further improve the acoustic effect. become.
