Abstract
The utility disclose a acoustic diffusion sound absorption body combination belonging to acoustic field, especially a sound-adjusting acoustic absorption body which is mainly composed of sound-absorbing material layer, protection layer and decoration layer; it is characterized in that the acoustic absorption body is column-shaped. The utility has beneficial effect of novel and simple structure, agile combination, artistic aesthetic sensibility, convenient assemblage, dual sound insulation and diffusion effect, thereby ensuring comfort of sound listener and avoiding acoustic focusing and auditory fatigue, effectively controlling sound and eliminating strong harmful echo, and promoting language definition; The present utility has low cost, good performance, and is simply manufactured and widely used in indoor acoustic design for halls for performance or room for sound recording and playback such as recording room, control room, church, audiovisual studio, assembly hall and cinema.
Description
[technical field]
The combination of a kind of acoustics diffusion of the utility model sound absorber belongs to field of acoustics, the acoustics sound absorber that particularly a kind of sound is regulated.
[background technology]
Usually in interior decoration, especially drill in the room of the class hall and sound recording and playback in sight, the indoor tone quality design is absolutely necessary.Various Acoustic treatment materials are 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
The room of most sound recording and playback such as recording room, control room, audiovisual studio, movie theatre 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.
[summary of the invention]
Task of the present utility model overcomes the deficiencies in the prior art exactly, and a kind of acoustics sound absorber is provided, and has good acoustically effective.
The utility model adopts following technical proposals: a kind of acoustics sound absorber, and sound absorber mainly is made up of sound-absorbing material layer, overcoat, decorative layer, it is characterized in that, and the sound absorber profile is a column.
Described sound absorber profile is cylindrical.
Described sound-absorbing material layer adopts polyester fiber, sponge, glass wool, mineral wool, wool, aluminum foam plate or glass foam, cotton fiber, chemical fibre to make.
Be provided with framework between described sound absorber decorative layer and overcoat.
The cross section of described sound absorber is a polygon.
The bottom of described sound absorber is provided with base.
Described decorative layer is that the material material of entrant sound is made.
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.
The beneficial effects of the utility model, novel structure, simple, combination is rich in aesthetic flexibly, easy for installation, have sound absorption and scattering double effects concurrently, 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, and the room acoustics that is widely used in seeing the room of drilling the class hall, all kinds of sound recording and playback such as recording room, control room, church, audiovisual studio, assembly hall, movie theatre etc. designs.
[description of drawings]
Fig. 1 is the structural representation of sound absorber of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Referring to Fig. 1, Fig. 2,1 is decorative layer, and 2 is overcoat, and 3 is sound-absorbing material layer.
[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 acoustics sound absorber, sound absorber mainly is made up of sound-absorbing material layer, overcoat, decorative layer.
Simpler production process of the present utility model:
Sound absorber: referring to Fig. 1, Fig. 2, the attached one deck overcoat 2 of the external surface of sound-absorbing material layer 3 is packaged in the overcoat front surface with decorative layer 1 then.
