Abstract
The utility model relates to the design field of building materials and discloses a diffuser which comprises a diffusing face panel, a support back panel and acoustic panels. The edge of the diffusing face panel is in butt joint with the edge of the support back panel to form a cylindrical body. The acoustic panels are arranged on the top and at the bottom of the cylindrical body. Sound-absorbing cotton is arranged on the inner surface of the cylindrical body in a laying mode. The diffusing face panel is in a circular arc shape. The support back panel is in a fan shape. An angle of a central angle corresponding to the fan shape is greater than 0 degree, less than and equal to 180 degrees. The semidiameter of the fan shape is from 100 millimeters to 400 millimeters. A light-emitting diode (LED) lamp with 12 volts is arranged on the inner wall of each acoustic panel. A through hole is formed in each acoustic panel. An inverted triangular hanging part is arranged on the outer wall of the support back panel. The thickness of the diffusing face panel is 15 millimeters to 25 millimeters. The thickness of the support back panel is 10 millimeters to 20 millimeters. The most appropriate thickness of the diffusing face panel is 20 millimeters and the most appropriate thickness of the support back panel is 12 millimeters. The diffuser has the advantages of being capable of effectively diffusing sound field and avoiding voice vibration, echo and secondary noise.
Description
Technical field
The utility model constructional materials design field relates in particular to a kind of diffuser.
Background technology
Under the test case of pure tone or narrow-band noise power, the low-frequency range of having a surplus does not reach diffusion very little because of the vibration damping vibration mode that has been excited.In addition, in the environment of the higher constructional materials of absorption coefficient because strong especially in the absorption of 10 square metres of effects, so that the diffusion of room sound field becomes very poor.Therefore, requiring high-end indoor characteristic and flutter, the echo that indoor wall causes and the quadratic noise that resonates and produce that needs to solve because of sound wave itself such as the opera house of sound dffusion, concert hall, recording studio, leisure club.
Summary of the invention
The purpose of the utility model embodiment is: a kind of diffuser is provided, and effective diffuse sound field avoids occurring the problem of flutter, echo and quadratic noise.
A kind of diffuser that the utility model embodiment provides comprises diffusion panel, supporting back board and acoustical board; The edge of described diffusion panel and the edge butt joint of described supporting back board are combined into column; Described acoustical board is positioned at top and the bottom of described column; It is cotton that described column inner surface is equipped with sound absorption.
Optionally, described diffusion panel is circular-arc.
Optionally, described supporting back board is fan-shaped.
Optionally, the angle of the central angle of described fan-shaped correspondence is greater than 0 degree, less than or equal to 180 degree.
Optionally, described fan-shaped radius is 100 ~ 400mm.
The LED lamp of 12V optionally, is installed on the inwall of described acoustical board.
Optionally, have through hole on the described acoustical board.
The suspension member of inverted triangle optionally, is installed on the described supporting back board outer wall.
Optionally, the thickness of described diffusion panel is 15 ~ 25mm, and the thickness of described supporting back board is 10 ~ 20mm.
Optionally, the thickness of described diffusion panel is 20mm, and the thickness of described supporting back board is 12mm.
Therefore, use the technical scheme of the utility model embodiment, form column by diffusion panel and described supporting back board, and abatvoix is installed in top and bottom at described column, lay the sound absorption cotton at described column inner surface, thereby so that the problem of vibration, echo, quadratic noise appears in indoor sound in communication process, and so that indoor sound reaches good sound dffusion effect.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
The structural representation of a kind of diffuser that Fig. 1 provides for the utility model embodiment 1;
The top view of a kind of diffuser that Fig. 2 provides for the utility model embodiment 1;
The top view of a kind of diffuser that Fig. 3 provides for the utility model embodiment 2.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment 1:
As depicted in figs. 1 and 2, diffuser described in the utility model comprises diffusion panel 1, supporting back board 2 and acoustical board 3, described diffusion panel 1 is circular-arc, described supporting back board 2 is fan-shaped, and the angle of the central angle of described fan-shaped correspondence is 90 degree, and namely described supporting back board 2 is mutually vertical.The edge butt joint of the edge of described diffusion panel 1 and described supporting back board 2 is combined into column, and 3 of described acoustical boards are positioned at top and the bottom of described column, is equipped with sound absorption cotton (not shown in FIG.) at described column inner surface simultaneously.At the inwall of described acoustical board 3 the LED lamp 4 of 12V is installed, power is 1W, is indoor construction lighting effects, has through hole 5 on the described acoustical board 3 simultaneously, so that the better effects if of sound absorption.
Wherein, described fan-shaped radius is between 100 ~ 400mm, and for described fan-shaped radius, radius is larger, and then corresponding acoustically effective is just better.And because the number of degrees of the central angle of described fan-shaped correspondence are 90 degree, namely supporting back board 2 is mutually vertical, thereby so that described diffuser can install at the corner in room, and so that the space that takies minimize.Simultaneously, the thickness of described diffusion panel 1 is at 15 ~ 25mm, the thickness of described supporting back board 2 is 10 ~ 20mm, optimum selection is 20mm for the thickness of described diffusion panel then, the thickness of described supporting back board is 12mm, not only can reach good sound dffusion effect, on consumables cost, also be unlikely very high simultaneously.
For improvement of the technical scheme, the suspension member 6 of inverted triangle is installed at the outer wall of described supporting back board 2.Described suspension member 6 is convenient to described diffuser integral body is hung on the metope, and is simple to operate, convenient.
For further improvement in the technical proposal, at the middle part of described supporting back board 2 inwalls gripper shoe 7 is installed also.The installation of described gripper shoe 7 is so that the structure of described column is more firm.
Embodiment 2:
Present embodiment only is with embodiment 1 difference: the angle of described fan-shaped corresponding central angle be 162 degree as shown in Figure 3, other embodiment 1 is identical.Certainly, this angle can be greater than 0 degree, less than or equal to any one angle of 180 degree, decides according to user's request.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
