Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1, the present invention discloses an acoustic wall 20 provided on an original wall 10. The original wall 10 is arranged vertically. The acoustic wall 20 includes a first wall 21 and a second wall 22, the second wall 22 is located on the upper side of the first wall 21, the first wall 21 is vertically arranged, the second wall 22 is obliquely arranged, and an obtuse angle is formed between the wall surface of the second wall 22 and the wall surface of the first wall 21. The acoustic wall 20 can adopt a wall plate type structure, acoustic structures and modules for inhibiting standing waves can be arranged between the wall plate type structures to form a box body structure, the box body structure can form various treatments aiming at different frequency bands of sound through the change of the facing, the treatment is very flexible, and the box body structure is embedded and does not protrude out of the facing part, so that the effective space volume of the room acoustics is increased.

In the present invention, the inclined acoustic wall 20 is constructed to have a thickness gradually increasing from bottom to top, thereby maintaining more floor area. The thickness from the top of the acoustic wall 20 to the acoustic ceiling is greater than that of a conventional acoustic wall, which provides a significant improvement in the sound absorption efficiency of the top.

Referring to fig. 2-5, first wall 21 includes a plurality of sets of acoustically reflective elements. The acoustic reflection assembly includes a plurality of reflection plates 40, and the plurality of reflection plates 40 are arranged in parallel at equal intervals, and high-frequency absorption can be completed due to gaps existing between the reflection plates 40. Due to the arrangement of the plurality of reflection plates 40, the adjustment and design of the acoustic performance of the acoustic wall 20 can be realized by changing the gaps between the plurality of reflection plates 40 and the inclination direction of the reflection plates 40.

The reflection assembly includes an outer frame 30, and the outer frame 30 includes a fixing member 31 and a mounting member 32, the fixing member 31 is connected to the mounting member 32, the fixing member 31 is fixed to the original wall 10, and the mounting member 32 is disposed perpendicular to the original wall 10. A plurality of reflection plates 40 are disposed inside the outer frame 30. The fixing member 31 may be a batten.

The end of the reflection plate 40 is fixed to the original wall 10, and the reflection plate 40 is disposed to be inclined with respect to the original wall 10. The plurality of reflection plates 40 in each group of reflection assemblies are inclined in the same direction, and the inclination directions of the reflection plates 40 in the different groups of acoustic reflection assemblies are not the same. Therefore, the acoustic regulation and control can be realized by matching the multiple groups of reflection assemblies.

In another embodiment, a sound absorbing material may be filled in a gap between two adjacent reflection plates 40, so that acoustic absorption and reflection coefficients can be controlled.

The reflection plate 40 has a right-angled trapezoidal structure. The right-angle side is arranged close to the original wall 10, and the distance between the bevel side and the original wall 10 is gradually increased from bottom to top.

The second wall 22 also includes an obliquely disposed acoustic layer 50. The acoustic layer 50 may be an acoustic panel having a first reflection and absorption of western energy.

The second wall 22 further comprises a fixing component 60 for accommodating the sound, the fixing component 60 is fixedly arranged on the original wall 10, and an accommodating groove 63 for accommodating the sound is formed in the fixing component 60. The fixing assembly 60 may be composed of a back plate 61 and four side plates 62, the four side plates 62 being disposed around the back plate 61 to form a receiving groove 63 with the back plate 61. The sound box can be placed in the accommodating groove 63, and thus, the structure is more compact.

The invention also comprises a first cloth layer 70, and the first cloth layer 70 is laminated on the surfaces of the first wall body 21 and the second wall body 22. The first fabric layer 70 is a veneer, and the first fabric layer 70 can block the acoustic reflection component, so that the first wall 21 and the second wall 22 have an aesthetic structure. And the first cloth groove is also provided with a through hole 71, and the through hole 71 is communicated with the accommodating groove 63, so that the sound box can be conveniently placed.
