Abstract
The utility model relates to the technical field of sound component, and particularly to a wall surface acoustic-treatment diffusion sound absorber with a triangular pyramid structure, which comprises a plurality of hollow diffusion sound absorbing units and a bottom plate, wherein the plurality of hollow diffusion sound absorbing units are made of hard material with a reflection effect. The figure of each diffusion sound absorbing unit has a hollow triangular prism structure which has two end openings at two ends. Two end openings of the diffusion sound absorbing unit are provided with sound absorbing layers. The diffusion sound absorbing units are uniformly arranged along a same sequence. One side surface of each diffusion sound absorbing unit is adhibited on the bottom plate. The angles among the diffusion sound absorbing units can be changed according to design requirement thereby changing a proportion between absorbed sound and diffused sound. The wall surface acoustic-treatment diffusion sound absorber with triangular pyramid structure has the following beneficial effects: novel and simple structure, dual effects of sound absorption and sound diffusion, capacity for ensuring comfortableness of a listener in long-time working, hearing fatigue prevention, harmful strong reflected sound elimination, sound focusing prevention, language definition increase, simple manufacturing, low cost, high performance and high generalization value.
Description
[technical field]
The utility model relates to the sound part technical field, a kind of specifically triangular prism structure wall Acoustic treatment diffusion sound absorber.
[background technology]
Drill in the room of the class hall and sound recording and playback in sight, the indoor tone quality design is absolutely necessary, and various Acoustic treatment material is combined in the interior decoration with structure.The sound absorption of indoor wall can be eliminated harmful strong reflection sound, avoids sound focus, reduces the room reverberation time, reduces the reverberation sound level, be improved speech articulation.In common interior decoration, sound absorption is to be provided by different walls with diffusion, fits up the diffusion wall that is adopted at present and also lacks sound absorbing capabilities usually, although the reflected sound diffusion is propagated, does not reduce reverberation acoustic energy, so the uncontrollable reverberation time.
The room of most sound recording and playback such as recording room, control room, audiovisual studio, home theater etc., room-sized is smaller usually, but very high to the requirement of tonequality.Promptly require in listening area last time the sound level of reflected sound will be, but need certain of short duration reverberation time,, avoid auditory fatigue with the comfortableness that guarantees that the auditor works long hours far below the direct sound sound level.Hydrogen can not adopt the full sound absorption design as sound attenuation room, and the sound absorption of wall and diffusion are combined.But in this class cubicle,,, can increase the difficulty of design, and be unfavorable for effective control of sound if sound absorption is provided by different walls respectively with diffusion because the wall area is limited.
[utility model content]
Task of the present utility model overcomes the deficiencies in the prior art exactly, and a kind of triangular prism structure wall Acoustic treatment diffusion sound absorber is provided, and has sound absorption and diffusion effect.
The utility model adopts following technical proposals: a kind of triangular prism structure wall Acoustic treatment diffusion sound absorber, comprise several hollow diffusion sound absorption units, the base plate made by the hard material of reflecting effect, it is characterized in that: described each diffusion sound absorption unit profile is the hollow triangular prism structure of both ends open, the port, two ends of described diffusion sound absorption unit is provided with sound absorbing layer, described diffusion sound absorption unit is by the identical evenly distributed combination of order, and described diffusion sound absorption one side, unit sticks on the base plate; Can change the angle that spreads between the sound absorption unit according to designing requirement, thereby change the ratio of sound absorption and diffusion.
Described diffusion sound absorption unit adopts good paulownia plank or the aluminium alloys of reflecting effect to make.
Described sound absorbing layer adopts the polyester fiber plate to make.
The profile of the other two sides of described diffusion sound absorption unit is the upper base weak point long isosceles trapezoid of going to the bottom.
Operating principle of the present utility model: the hard material surface that arrives the diffuse sound body when sound wave will reflect to different directions at the sound wave of same frequency, optimize the uniformity of sound; In the time of sound wave process diffusion sound absorber side, side or inner damping material can be converted into heat energy with acoustic energy, have reached good acoustically effective.
The beneficial effects of the utility model: novel structure, simple, have sound absorption and diffusion double effects concurrently, guarantee the work long hours comfortableness of acoustic surrounding of auditor, avoid auditory fatigue, eliminate harmful strong reflection sound, avoid sound focus, improve speech articulation; In addition, the utility model is made simple, and cost is low, and performance is good, is worthy of popularization.

Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the horizontal schematic diagram of Fig. 1;
Fig. 3 is the side view of Fig. 1;
Fig. 4 is base arrangement figure of the present utility model.
Among the figure: 1 is that hollow triangular prism, 2 is that sound absorbing layer, 3 is base plate.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Diffusion sound absorption unit profile of the present utility model is hollow triangular prism 1, and it can be made up of the good paulownia plank of reflecting effect, also can be to draw the aluminium alloys triangular prism that forms by mould; The port, two ends of described diffusion sound absorption unit is provided with sound absorbing layer 2, and the sound absorbing layer material is the polyester fiber plate, plays the hollow triangular prism of sealing on the structure.Hollow triangular prism 1, hollow diffusion sound absorption unit of sound absorbing layer 2 common formations.Be the upper base weak point long isosceles trapezoid of going to the bottom referring to the profile of the other two sides of the described diffusion of Fig. 2 sound absorption unit.
In conjunction with Fig. 1, each diffusion sound absorption unit same sequence is arranged time to base plate 3 successively, and is can glue bonding, also can connect with the mosquito nail with tapping screw or carpenter.Totally 36 spread sound absorption unit is formed a 600 * 600mm with base plate diffusion sound absorber.
According to circumstances need, the periphery of diffusion sound absorber can add the frame work in combination.
