Abstract
The utility model relates to the field of sound parts, in particular to an improved wall acoustic treatment diffsorber which mainly comprises a plurality of units consisting of materials with different density and with reflection effect, wherein the shape of each unit is a gengon; part of units adopt reflexive material to paste the surface so as to form reflectors; all the units are arbitrarily arranged, combined and stuck together on the same plane or stuck on a bottom plate to form the diffsorber; and the periphery of the diffsorber is covered by sound transparent cloth. The diffsorber has the following benefits: the diffsorber having simple structure and consisting of materials with different density can absorb acoustic waves with different frequency bands, has wider absorption frequency range than the sound absorber and diffsorber made of single material, gives consideration to diffusion and sound absorption performances, ensures the long-time work comfortableness of the listener, avoids auditory fatigue, and can effectively control sound, eliminate harmful strong reflected sound, avoid sound focus and improve speech articulation.
Description
[technical field]
The utility model relates to the sound part technical field, a kind of specifically modified 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 and material with scattering, fits up the scattering wall that is adopted at present and also lacks sound absorbing capabilities usually, although the reflected sound diffusion is propagated, but do 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 naturality, the comfortableness that guarantees that the auditor works long hours far below the direct sound sound level.So can not adopt the full sound absorption design as sound attenuation room, and should make the sound absorption and the scattering phase combination of wall.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 and material respectively with scattering because the wall area is limited.
[summary of the invention]
Task of the present utility model overcomes the deficiencies in the prior art exactly, and a kind of modified wall Acoustic treatment diffusion sound absorber is provided, and has sound absorption and dispersion effect.
The utility model adopts following technical proposals: a kind of modified wall Acoustic treatment diffusion sound absorber, main several unit of forming by the different densities material of reflecting effect, it is characterized in that: each unit profile is a gengon, wherein the part unit adopts reflective material to paste the surface and forms reflecting surface, the any at grade permutation and combination in described each unit is pasted together or sticks on the base plate, form the diffusion sound absorber, at the sonolucent cloth parcel of the peripheral employing of described diffusion sound absorber, can keep elegant in appearance.
Described each unit profile is a cuboid, and described diffusion sound absorber profile is a big cuboid, and the junction between each unit is provided with the hard material lattice framing, is used for fixing and strengthens diffusivity.
Described hard material lattice framing is the glass steel bar.
Described reflective material is an aluminium-foil paper.
Edge is provided with cornerite around the described diffusion sound absorber.
Operating principle of the present utility model: the diffusion of sound and absorption are two kinds of different qualities of same acoustic interface, any moment all is coefficient, on the basis of comparative maturity sound absorption and diffusion theory, in conjunction with the pseudorandom theory in the number theory, adopt the acoustical material combination of different acoustics index and shape, can design multiple diffusion sound absorber at different frequency range, different sound absorption diffusion effects.When sound wave arrives the material surface of the different densities of diffusion sound absorber, sound waves of different frequencies will reflect to different directions, optimize the uniformity of sound; Simultaneously, in the time of sound wave process diffusion sound absorber, its surface and inner sound absorption 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, because the diffusion sound absorber that adopts the different densities material to form, can absorb the sound wave of different frequency section, sound absorber, the diffusion sound absorber made than homogenous material, its absorption frequency scope is wideer, and taken into account the performance of the diffusion and two aspects that absorb sound, and guarantee the comfortableness that the auditor works long hours, avoid auditory fatigue, can effectively control sound, 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.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the drawing in side sectional elevation of Fig. 1;
Referring to Fig. 1 to Fig. 2: 1 for cuboid unit (the glass body that the polylith different densities is arranged respectively), 2 for base plate, 3 for glass steel bar, 4 for entrant sound cloth, 5 is reflecting surface, 6 is cornerite.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Embodiment one: referring to Fig. 1, Fig. 2, a kind of modified wall Acoustic treatment diffusion sound absorber, taking into account the fiber-like of the different densities of diffusion and sound absorbing capabilities forms, the glass body of different densities is a unit, each unit can directly fasten with glue together or increase the glass steel bar in the centre, permutation and combination sticks on the base plate 2 or the direct sonolucent cloth 4 of outsourcing tool without base plate, the part unit adopts the aluminium-foil paper material to paste the surface and forms reflecting surface 5, and edge is provided with cornerite 6 around the diffusion sound absorber that forms.Require diffusion different with the height of sound absorption according to varying environment, the density of glass body can be done different the adjustment, and the glass steel bar can not increase yet, and it can play fixation on the one hand, can increase diffusivity on the other hand.
