Fig. 2 is a kind of structural schematic diagram of the embodiment one of novel wedge absorber provided by the utility model；
Fig. 3 be in embodiment one a kind of novel wedge absorber provided by the utility model to the absorption for spilling into the sound wave penetrated and
Reflect schematic diagram；
Fig. 4 is a kind of structural schematic diagram of the embodiment two of novel wedge absorber provided by the utility model；
In figure: 1 is base portion, and 2 be tip, and 10 be wedge main body.
Specific embodiment
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and embodiment
The utility model is described in further detail.
Referring to fig. 2, Fig. 3, the utility model provide a kind of novel wedge absorber, including multiple set in parallel in vertical direction
The wedge main body 10 (being not limited to Fig. 2, two shown in Fig. 3) set, each wedge main body 10 include a base portion 1；
The upper end of each base portion 1 has a tip 2；
The lower end of the adjacent base portion 1 of any two is connected.
In the present invention, in specific implementation, the shell of each wedge main body 10 be using metal material (such as
Aluminium) made of perforated plate, such as can be the perforated metal panel zinc-plated with a thickness of the surface of 0.8mm.
In the present invention, in specific implementation, the corner of each wedge main body 10 is to be welded to connect.
In the present invention, in specific implementation, the interior of shell of each wedge main body 10 is filled with sound-absorbing material,
The sound-absorbing material is preferably glass fibre, such as can be the glass fibre manufactured using long fibre moulding process, such as U.S.
The super glass wool of OWENS CORNING company production.
In the present invention, in specific implementation, entrant sound sealing is enclosed with outside the sound-absorbing material (such as glass fibre)
Film, the entrant sound seal film as armour layer, are arranged between the shell (i.e. perforated plate) of wedge main body 10 and sound-absorbing material, can use
In preventing completely short grained substance (i.e. internal glass fibre) leakage and to make this practical without influencing its acoustical behavior
The novel wedge absorber of novel offer can reach the air quality standard of national requirements.Simultaneously as the presence of entrant sound sealing film,
Even if the shell exterior of the wedge main body 10 has the air-flow of high speed, the sound-absorbing material of inside filling will not be escaped, to protect
The acoustical behavior for demonstrate,proving wedge is stablized.
In the present invention, in specific implementation, referring to fig. 2 and shown in Fig. 4, tip 2 in each wedge main body 10
Top be tip or flush configuration.Therefore, for the utility model, guaranteeing that acoustical behavior is excellent, production technology simplifies,
Product quality is greatly improved with reliability.
It should be noted that, since the tip of wedge absorber shown in FIG. 1 is very thin, this gives for the utility model
Wadding causes great difficulty, it is also difficult to guarantee that sound-absorbing material is completely filled inside wedge main body 10, therefore, this is practical new
Type can be further, is flush configuration by the tip designs of tip 2 in each wedge main body 10, as shown in Figure 4.
In the present invention, in specific implementation, the left and right sides of tip 2 are song in each wedge main body 10
Face.
In specific implementation, the curved surface is specially arc-shaped concave curvature.
In specific implementation, as shown in Figure 1, the portion that the arc-shaped concave curvature is connected with the top of the tip 2
Divide and is mutually perpendicular to the horizontal plane where the tip 2.
Therefore, shown in Figure 3 according to ray acoustics knowledge, in addition to glancing incidence sound wave, remaining directive sound wave of institute is all
Multiple reflections will be carried out between two tips for entering wedge main body and be efficiently absorbed.This point is different from linear type wedge,
Existing linear type wedge is to the reflection schematic diagram for spilling into the sound wave penetrated as shown in figure 4, for spilling into the sound wave penetrated (i.e. from surrounding
Disperse the sound wave injected), linear type wedge will directly be reflected.Therefore, for the utility model, if anechoic room is all adopted
With the novel wedge absorber of the utility model, then will be helpful to improve the quality of free found field in anechoic room.
It is based on above technical scheme it is found that for the utility model, the shelling machine of wedge absorber is certain at having
The curve form of geometric parameter meets the basic principle of wedge, simultaneously, additionally it is possible to increase the aesthetics of wedge.The utility model
The tip of the novel wedge absorber provided uses arc-shaped curved design, simple production process, the geometric form of designed curved surface
Shape can substantially reduce the reflection of scattered incident acoustic wave.
It should be noted that as previously described it is found that for the utility model, the novel wedge absorber provided, wedge master
10 shell of body is perforated metal panel, and the corner of wedge main body 10 is mostly to be welded to connect, rugged construction, securely, and due to appearance
Face is fully wrapped around by metal, and surface anticollision, protecting against shock are functional.
In conclusion compared with prior art, a kind of novel wedge absorber provided by the utility model can allow suction
Sound wedge can effectively be absorbed to spilling into the sound wave penetrated, and reduce the reflection to the sound wave penetrated is spilt into, and improve wedge absorber
Whole sound absorption effect, be conducive to widely promote and apply, be of great practical significance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
