Abstract
The utility model discloses a kind of triangle inclined-plane diffusers, including diffusion substrate and reflecting plate, the shape of the reflecting plate is the tetragonous pyrometric cone formed after a square is diagonally cut, the reflecting plate and diffusion substrate are integrally formed, reflecting plate entanglement is arranged on diffusion substrate, and the face that reflecting plate and diffusion substrate contact with each other is the face where square composed by right-angle side.The utility model can make openr sound, clear and natural, true full, vibration echo and piping, other various places high to acoustical demands suitable for home theater, hotel, dancing hall, nightclub, KTV box, music hall, multifunctional hall, studio, recording studio, cinema, advanced office, meeting room, indoor sport shop, library, exhibition center, classroom, Classroom etc. can effectively be avoided.
Description
Technical field
The utility model belongs to architectural acoustics technical field, more particularly to a kind of triangle inclined-plane diffuser.
Background technique
In architectural acoustics, acoustics diffusion be it is essential, in the metope or smallpox for not doing DIFFUSION TREATMENT, vertical and
Horizontal direction will form the superposition phenomenon of multiple reflections sound and direct sound wave, lengthen the room reverberation time, and sound cannot disappear for a long time
It dissipates, the clarity so as to cause indoor sound is inadequate, it is difficult to use.
The Chinese patent of 2705513 Y of Patent No. CN points out that traditional diffuser plate is by height phase in the background technology
Same platform composition, uneven to the reflection of sound, the absorption simultaneously for sound does not work, and cannot reach preferable sound
Effect.
Therefore, the emphasis how to solve the above problems as those skilled in the art's research.
Utility model content
The purpose of this utility model is just to provide a kind of triangle inclined-plane diffuser, can be fully solved the above-mentioned prior art not
Foot place.
The purpose of this utility model is realized by following technical proposals:
A kind of triangle inclined-plane diffuser, including diffusion substrate and reflecting plate, the shape of the reflecting plate are a square
The tetragonous pyrometric cone formed after diagonally cutting, the reflecting plate and diffusion substrate are integrally formed, and reflecting plate entanglement setting exists
On diffusion substrate, the face that reflecting plate and diffusion substrate contact with each other is the face where square composed by right-angle side.
Preferably, the diffusion substrate is quadratic remainder diffuser plate.
Preferably, being filled with silencing cotton in the reflecting plate.
Compared with prior art, the utility model has the beneficial effects that:
1, the utility model structure is simple, keeps sound openr, clear and natural；
2, reduction sound rate slackens in the air, avoids the escape of sound, keeps sound really full；
3, vibration echo is avoided, the sound defects such as sound focusing are reduced；
4, sharp sound quality is reduced, keeps sound perception more comfortable, calm nerves fatigue.
Detailed description of the invention
Fig. 1 is the front view of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment
The utility model is further described with attached drawing combined with specific embodiments below.
Embodiment one
As shown in Figure 1 and Figure 2, a kind of triangle inclined-plane diffuser, including diffusion substrate 1 and reflecting plate 2, diffusion substrate 1 are long
600mm, width 600mm, high 10mm, diffusion substrate 1 are that the quadratic remainder of Shanghai Sheng Zhu Environmental Protection Technology Co., Ltd production spreads base
Plate, the shape of reflecting plate 2 are the tetragonous pyrometric cone formed after the square that a side length is 90mm is diagonally cut, reflecting plate
2 with diffusion substrate 1 be on same wood plank or PET sheet be integrally formed formed, 2 entanglement of reflecting plate be arranged on diffusion substrate 1,
The face that reflecting plate 2 and diffusion substrate 1 contact with each other is the face where square composed by right-angle side, diffusion substrate 1 and reflection
The surface of plate 2 is all covered with GRG (precasting type glass fibre reinforcement gypsum) spray coating, which can support to a certain extent
Diffuser cracking or deformation caused by imperial external environment.
The utility model can make openr sound, clear and natural, true full, can effectively avoid vibration echo and point
Sharp sound is suitable for home theater, hotel, dancing hall, nightclub, KTV box, music hall, multifunctional hall, studio, recording
Other are various right for room, cinema, advanced office, meeting room, indoor sport shop, library, exhibition center, classroom, Classroom etc.
The high place of acoustical demands.
Embodiment two
As shown in Figure 1 and Figure 2, a kind of triangle inclined-plane diffuser, including diffusion substrate 1 and reflecting plate 2, diffusion substrate 1 are long
700mm, width 700mm, high 15mm, the shape of reflecting plate 2 are to be formed after the square that a side length is 85mm is diagonally cut
Tetragonous pyrometric cone, reflecting plate 2 and diffusion substrate 1 are to be integrally formed to be formed on same wood plank or PET, 2 entanglement of reflecting plate
It is arranged on diffusion substrate 1, the face that reflecting plate 2 and diffusion substrate 1 contact with each other is the place of square composed by right-angle side
The surface of face, diffusion substrate 1 and reflecting plate 2 is all covered with GRG (precasting type glass fibre reinforcement gypsum) spray coating.
Embodiment three
As shown in Figure 1 and Figure 2, a kind of triangle inclined-plane diffuser, including diffusion substrate 1 and reflecting plate 2, diffusion substrate 1 are long
700mm, width 700mm, high 20mm, the shape of reflecting plate 2 are to be formed after the square that a side length is 80mm is diagonally cut
Tetragonous pyrometric cone, reflecting plate 2 and diffusion substrate 1 are to be integrally formed to be formed on same wood plank or PET sheet, and reflecting plate 2 is wrong
Disorderly it is arranged on diffusion substrate 1, the face that reflecting plate 2 and diffusion substrate 1 contact with each other is the place of square composed by right-angle side
Face, the surface of diffusion substrate 1 and reflecting plate 2 is all covered with GRG (precasting type glass fibre reinforcement gypsum) spray coating.
In the present embodiment, reflecting plate 2 is hollow structure, and lumen loading has silencing cotton, this design is so that diffuser has
The function of sound-absorbing and diffusion, especially suitable for small Space, Place.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
