Abstract

The utility model relates to the technical field of sound parts, in particular to a wall surface acoustic processing scatterer, which is mainly composed of a frame, inserting plates and plane plates. The wall surface acoustic processing scatterer is characterized in that multiple pieces of inserting plates which are parallel mutually are installed in the frame, the plane plate which is vertical to each inserting plate is arranged on the bottom end of each inserting plate, the other end of the plane plate is connected with a wood strip of a side panel of the frame, an 'L'-shaped sound absorbing cavity is formed between the inserting plate and the plane plate which are neighboring, the wall surface acoustic processing scatterer has the beneficial effects of novel and simple structure and has the scattering effect, the long time work comfortableness of sound listeners is guaranteed, the auditory fatigue is avoided, sound can be effectively controlled, sound focus is avoided, the speech definition is improved, and furthermore the wall surface acoustic processing scatterer has simple manufacture, low cost and good performance, and is worthy of being extended and applied.

Description

A kind of wall Acoustic treatment scattering object
[technical field]
The utility model relates to the sound part technical field, specifically a kind of wall Acoustic treatment scattering object.
[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 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, 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 0 reverberation time of certain weak point,, avoid auditory fatigue with 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 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 wall Acoustic treatment scattering object is provided, and has dispersion effect.
The utility model adopts following technical proposals: a kind of wall Acoustic treatment scattering object, mainly form by framework, plate and surface plate, it is characterized in that: the some plates that are parallel to each other are equipped with in described framework inside, the bottom of every plate is provided with the surface plate perpendicular with it, the other end of surface plate is connected on the batten of side panel of framework, forms one " L " shape sound-absorbing cavity between adjacent plate and the surface plate.
Above-mentioned plate is processed several gap slots foremost, at the notch insertion acoustical plate of gap slot.
Operating principle of the present utility model: sound wave enters in the cavity of scattering object formation, sound waves of different frequencies will reflect to different directions, optimized the uniformity of sound, simultaneously under the situation that does not change product thickness, strengthened the sound absorption frequency of product, sound wave through repeatedly reflection collision, is converted into heat energy with material generation rubbing action with acoustic energy in cavity, reached good Acoustic treatment effect.
The beneficial effects of the utility model, novel structure, simple has dispersion effect, guarantees the comfortableness that the auditor works long hours, and avoids auditory fatigue, can effectively control sound, avoids sound focus, improves 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 sectional drawing of Fig. 1.
Referring to Fig. 1, Fig. 2,1 is framework, and 2 is plate, and 3 is the sound-absorbing cavity, and 4 is side panel, and 5 is surface plate, and 6 is the broadside batten, and 7 is batten.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Referring to Fig. 1, Fig. 2, a kind of wall Acoustic treatment scattering object, mainly form by framework 1, plate 2 and surface plate 5, the plate 2 that 2N-1 (N 〉=2) sheet is parallel to each other is equipped with in framework inside, several sulculuses of place, the bottom of every plate processing, sulculus are used for mounting plane plate 5, and surface plate 5 is perpendicular with plate 2, the other end of surface plate 5 is connected on the batten 7 of side panel of framework, forms one " L " shape sound-absorbing cavity 3 between adjacent plate and the surface plate.Framework 1 can be the material with reflecting effect of any hard.
Manufacture craft of the present utility model:
1. earlier middle N piece plate is inserted on the upper and lower side frame of framework 1 inside;
2. the both sides inwall is respectively pasted by glue with N-1 (N 〉=2) batten and side frame, with glue both sides frame and upper and lower side frame is formed one again;
3. removing middle plate directly contacts with rear board, the plate of the right and left corresponding locational batten in side respectively is connected with surface plate by glue, batten the effect here is to increase adsorption area, make adsorptivity more stable, only outermost broadside batten is in order to form a cavity;
4. by glue rear board is sealed at last.
