Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound module such as a speaker, a sound insulation module, a sound absorption module, and a diffusion module.

[0002]

2. Description of the Related Art In recent years, listening rooms for enjoying high-fidelity music have become widespread, but the ease of construction has become an issue.

Generally, the speaker is used by placing it on the floor of the listening room or by mounting it on the wall, but it is preferable to install the speaker by embedding it in the wall in order to effectively use the space in the room. In response to such demands, we have already proposed a wall surface structure that can freely configure an interior wall by combining a thin speaker and various acoustic modules.

The wall structure proposed above will be described below with reference to the drawings. FIG. 4 shows the proposed wall structure in perspective view, and FIG. 5 shows its details in three views.
In FIG. 4, the joining bar 62 is horizontally fixed to the pillar 61. This tie bar 62, as shown in (FIG. 5),
One groove 62a is provided on the back side and two grooves 62a are provided on the front side.
Insert square nut 71 into both ends of 2a,
The connecting bar 62 is fixed to the column 61 by using the square nut 71 inserted in a, the L metal fitting 72, and the bolt 73.

On the other hand, the acoustic modules constituting the wall surface such as the sound absorbing module 63 and the diffusing module 64 are provided with four bolt holes 65 at four corners, and the coupling bar 62 and the square nut 71 inserted in the front surface are provided in the bolt holes 65. They are placed together and fixed with bolts 66 to form a wall surface.

[0006]

However, such a conventional wall structure has the following problems. (1) In the acoustic module that constitutes the wall surface such as the diffusion module 64, since the sound insulation structure and the member having various acoustic effects are integrally structured, the weight of one acoustic module increases, and the reverberation time is changed. Replacement work is difficult. (2) When the acoustic module such as the diffusion module 64 is attached, the head of the bolt 66 spoils the appearance because it is fixed with the bolt 66 from the surface side which is made up. (3) The wiring of the power supply line requires holes in the acoustic module when the acoustic module is attached.

The present invention solves the above-mentioned problems, and can be easily attached by an easy operation, and a wall surface can be quickly constructed without showing the head of the bolt which spoils the appearance. It is another object of the present invention to provide an acoustic module that can easily route complicated power lines.

[0008]

In order to achieve the above object, the present invention provides a pillar, a connecting bar horizontally fixed through the pillar L fitting, a flat sound insulating structure, and a sound diffusion. Acoustic panel having a surface that produces an effect or acoustic sound absorption effect, panel mounting pins with flange-shaped tips provided near the upper and lower ends of the back surface of the acoustic panel, and the panel mounting pin on one plane of the sound insulation structure And a panel mounting member having a keyhole-shaped mounting hole provided at a position to be inserted into the acoustic module.

Further, the acoustic module is an acoustic module in which an elastic body such as a rubber material is provided on the longitudinal outer periphery of the surface of the sound insulation structure.

[0010]

According to the present invention, in the above structure, the sound diffusion effect or the sound absorption effect is provided in the insertion hole through which the flange of the keyhole-shaped mounting member provided on one plane of the flat sound insulation structure fixed to the joining bar passes. With the elastic body provided on the vertical outer periphery of the surface of the sound insulation structure, by inserting the panel mounting pins with flange-shaped tips provided near the upper and lower ends of the back surface of the acoustic panel having the surface that causes ,
The surface panel can be installed quickly with tension applied, and the wall surface is constructed without showing the unsightly bolt heads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An acoustic module according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the structure of an acoustic module according to an embodiment of the present invention. As shown in (Fig. 1),
The sound insulation structure 1 having the four screw holes 1a at the four corners of the joining bar 62 fixed to the pillar 61 is passed through the screw holes 1a with four screws 5 and fixed to the joining bar 62. Then screw 9
Then, the panel mounting member 7 having the key holes 7a having the insertion holes through which the flanges pass is provided near the upper and lower ends on one plane on the one surface of the sound insulating structure 1. Further, two rubber sheets 4 are attached to the vertical outer periphery of the surface of the sound insulation structure 1. On the other hand, the panel mounting pins 8 having a flange-like tip are mounted near the upper and lower ends of the back surface of the acoustic panel 2 having a surface that produces a sound diffusion effect.

FIG. 2 is a sectional perspective view of an acoustic module of one embodiment of the present invention. Further, (FIG. 3) is a cross-sectional view showing a change of the acoustic module of the embodiment of the present invention. As shown in (FIG. 2) and (FIG. 3), the acoustic panel 2 in which the panel mounting pin 8 with the flange is press-fitted
While pressing against the surface of the sound insulation structure 1
It is inserted into the hole through which the flange of the key hole 7a of the panel mounting member 7 mounted on the. Next, the acoustic panel 2 is slid while being pressed against the surface of the sound insulation structure 1 and set at an arbitrary position. At this time, by the two rubber sheets 4 attached to the vertical outer periphery of the surface of the sound insulation structure 1,
The acoustic panel 2 is held with a constant spring force applied between the acoustic panel 2 and the acoustic panel 2.

[0014]

As is apparent from the above embodiments, the present invention provides a sound insulation structure in the form of a flat plate, an acoustic panel having a surface for producing a sound diffusion effect, and a back surface of the acoustic panel near the upper and lower ends thereof. There is provided a panel mounting pin having a flange-shaped tip, and a keyhole-shaped mounting hole provided at a position to be inserted into the panel mounting pin on one plane of the sound insulation structure, and the keyhole hole is a flange. By using an acoustic module that consists of a panel mounting member with insertion holes that go through at both ends as key holes, it is possible to quickly mount the front panel with a constant spring force applied, and the head of the bolt that spoils the appearance. The wall surface can be constructed without showing. In addition, the power lines can be routed in the space of the rubber material on the outer circumference of the surface of the sound insulation structure.
