Abstract
The utility model relates to the technical field of sound parts, in particular to an interface acoustic processing sound absorption body which is mainly composed of a base which is made of hard materials. The interface acoustic sound absorption body is characterized in that the outer shape of the base is a hollow multilateral body, multiple layers of sound absorption material layers are arranged inside the base, the interface acoustic sound absorption body has the beneficial effects that the structure is novel and simple, the sound absorption effect is provided, the long time work comfortableness of sound listeners is guaranteed, the auditory fatigue is avoided, sound can be effectively controlled, harmful strong reflected sound is eliminated, sound focus is avoided, the speech definition is improved, and furthermore the interface acoustic sound absorption body has simple manufacture, low cost and good performance, and is worthy of being extended and applied.
Description
[technical field]
The utility model relates to the sound part technical field, specifically a kind of interface Acoustic treatment 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 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 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.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 interface Acoustic treatment sound absorber is provided, and has acoustically effective.
The utility model adopts following technical proposals: a kind of interface Acoustic treatment sound absorber, mainly form a base by hard material, and it is characterized in that: described base profile is a gengon, and base inside is provided with the several layers sound-absorbing material layer.
Described base profile is a prismatoid.
Be provided with a layer entrant sound decorative layer in the outer visual layers of sound absorption material.
Have square groove on the rear side panel of described base, the aluminium web plate is housed in the square groove.
Operating principle of the present utility model: when the sound absorption material of sound wave by sound absorber, can go deep into material internal, acoustic energy is converted into heat energy, reach good acoustically effective with material generation rubbing action.Square groove on the base rear side panel also has certain entrant sound effect concurrently to sound simultaneously.
The beneficial effects of the utility model, novel structure, simple has acoustically effective, guarantees the comfortableness that the auditor works long hours, and avoids auditory fatigue, can effectively control sound, eliminates harmful strong reflection 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 another example structure schematic diagram of the present utility model.
Referring to Fig. 1, Fig. 2,1 is base, and 2 is sound-absorbing material layer, and 3 is the entrant sound decorative layer, and 4 is square groove, and 5 is the aluminium web plate.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Referring to Fig. 1, a kind of interface Acoustic treatment sound absorber, mainly form a base 1 by hard material, described base profile is a prismatoid, base inside is provided with several layers sound-absorbing material layer 2, the material of sound-absorbing material layer can be that glass fiber also can be any porous absorption material, (as: polyester fiber, sponge, glass wool, wool, aluminum foam plate or glass foam, cotton fiber, chemical fibre); Be provided with a layer entrant sound decorative layer 3 between sound-absorbing material layer and base inner wall, entrant sound decorative layer 3 can be the cotton carpet veneer of one deck.
Referring to Fig. 2, the utility model can also have square groove 4 on the rear side panel of base, aluminium web plate 5 is housed in the square groove.
Simpler production process of the present utility model:
1. three side panels and a rear board are linked together earlier and form the base of acoustic(al)absorbent with screw;
2. the several layers glass fiber is fastened with glue together, cut into the sound absorber shape, fill in then;
3. insert respectively in four metal square grooves on four limits of last layer of glass, compresses, and is stained with one deck cotton mat then on this layer glass fiber, is inserted at last in the base of sound absorber;
4. with screw that last side panel and other three side panels is fastening;
5. with screw last one deck is had metal edges and outside the illiteracy has the glass fiber of cotton mat and four side panels to link together.
Claims (5)
1. an interface Acoustic treatment sound absorber is mainly formed a base by hard material, it is characterized in that: described base profile is hollow gengon, and base inside is provided with the several layers sound-absorbing material layer.
2. interface as claimed in claim 1 Acoustic treatment sound absorber is characterized in that: described base profile is a prismatoid.
