DETAILED DESCRIPTION
[0024] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not limiting to the present application.
[0025] Reference Figure 1As shown, the present application discloses an acoustic wall 20 which is arranged on an original wall 10. The original wall 10 is arranged vertically. The acoustic wall 20 comprises a first wall 21 and a second wall 22, the second wall 22 is arranged on the upper side of the first wall 21, the first wall 21 is arranged vertically, the second wall 22 is arranged obliquely, and the wall surface of the second wall 22 forms an obtuse angle with the wall surface of the first wall 21. The acoustic wall 20 can adopt a wall panel structure, and the acoustic structure and module for suppressing standing wave can be arranged between the wall panel structures to form a box structure. The box structure can be composed of various sound processing structures for different frequency bands by changing the surface decoration, which is very flexible. Moreover, the box structure is embedded and does not protrude from the surface decoration, thereby increasing the effective acoustic space volume of the room.
[0026] In the present application, the thickness of the oblique acoustic wall 20 structure gradually increases from bottom to top, thereby reserving more ground area. The thickness of the acoustic wall 20 at the top to the acoustic ceiling is greater than that of the conventional acoustic wall, which significantly improves the sound absorption efficiency at the top.
[0027] Referring to Figures 2-5 As shown, the first wall 21 comprises a plurality of acoustic reflection assemblies. The acoustic reflection assembly comprises a plurality of reflection plates 40 which are arranged in parallel and at equal intervals. The gaps between the reflection plates 40 can complete high-frequency absorption. By arranging a plurality of reflection plates 40 and changing the gaps between the reflection plates 40 and the inclination direction of the reflection plates 40, the acoustic performance adjustment and design of the acoustic wall 20 can be realized.
[0028] The reflection assembly comprises an outer frame 30, and the outer frame 30 comprises a fixing member 31 and a mounting member 32. The fixing member 31 is connected with the mounting member 32, the fixing member 31 is fixed on the original wall 10, and the mounting member 32 is arranged perpendicularly to the original wall 10. The plurality of reflection plates 40 are arranged inside the outer frame 30. The fixing member 31 can be a wooden square.
[0029] The end of the reflection plate 40 is fixed to the original wall 10, and the reflection plate 40 is arranged obliquely relative to the original wall 10. The plurality of reflection plates 40 in each group of reflection assemblies are arranged in the same oblique direction, and the reflection plates 40 in different groups of acoustic reflection assemblies are arranged in different oblique directions. In this way, the plurality of groups of reflection assemblies cooperate to realize acoustic regulation and control.
[0030] In another embodiment, the gap between the adjacent two reflection plates 40 can be filled with sound-absorbing material, so that the acoustic absorption and reflection coefficients can be adjusted.
[0031] The reflection plate 40 has a right-angled trapezoidal structure. The right-angled side of the reflection plate 40 is arranged close to the original wall 10, and the distance between the oblique side of the reflection plate 40 and the original wall 10 gradually increases from bottom to top.
[0032] The second wall 22 further comprises an acoustic layer 50 arranged obliquely. The acoustic layer 50 can be an acoustic board having first reflection and absorption sound energy.
[0033] The second wall 22 further comprises a fixed assembly 60 for accommodating the sound equipment. The fixed assembly 60 is arranged fixedly on the original wall 10, and the fixed assembly 60 is provided with an accommodating groove 63 for placing the sound equipment. The fixed assembly 60 can be composed of a back plate 61 and four side plates 62 arranged around the back plate 61 to form the accommodating groove 63 with the back plate 61. The sound equipment can be placed in the accommodating groove 63, so that the structure is more compact.
[0034] The present application further comprises a first cloth layer 70 for covering the surfaces of the first wall 21 and the second wall 22. The first cloth layer 70 is a decorative surface, and the first cloth layer 70 can shield the acoustic reflection assembly, so that the first wall 21 and the second wall 22 have a beautiful structure. In addition, the first cloth layer 70 is provided with a through hole 71, which is in communication with the accommodating groove 63, so as to facilitate the placement of the sound equipment. The present application can further comprise a second cloth layer, which is fixed on the acoustic wall 20 by a magnet to cover the through hole 71, so as to realize the concealment of the sound equipment in the accommodating groove 63, and make the acoustic wall 20 more beautiful.
[0035] In an acoustic room, the height of 0-500mm from the ground usually has little acoustic significance, which is related to the height of the sound box from the ground, the height of the human ear, and the height of the sound pickup. It is known through practice that the height of the sound box, the human ear, and the sound pickup from the ground is above 1000mm, and the acoustic wall in the range of 0-500mm from the ground can be reduced correspondingly, so as to obtain the maximum ground area. Thus, the first wall 21 can be arranged in the range of 0-500mm from the ground. In the present application, since the wall is an oblique structure, the thickness of the top of the wall to the acoustic ceiling is greater than that of a conventional acoustic wall, which significantly improves the sound absorption efficiency of the top. Since the wall plate structure is adopted in the present application, the acoustic structure and module for suppressing standing waves can be installed between the wall plate structures to form a box structure. The box structure can be composed of various sound processing structures for different frequency bands through the change of the decorative surface, which is very flexible. In addition, since the box structure is embedded, it does not protrude the decorative surface part, and the acoustic effective space volume rate of the room is increased.
[0036] The above-described embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent replacement or transformation of the present application based on the present application is within the protection scope of the present application. The protection scope of the present application is subject to the claims.
