Description
Technical field
The invention belongs to the technical field of acoustics sound absorption structure, more particularly to a kind of spatial extent efficient plane sound absorption
Body.
Background technology
The absorption of low frequency acoustic energy, typically one technological difficulties.Such as common sound absorbent perforated structure, generally by wearing
Orifice plate and cavity composition below, and want have preferable acoustically effective to low frequency, it is necessary to the comparison that cavity is done is thick, but in reality
In the application of border, it is undesirable that it takes excessive space.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of spatial extent efficient plane sound absorber, have to low-frequency sound wave
There is good assimilation effect, reduce structural thickness.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of spatial extent efficient plane sound absorber,
Sound absorption monomer including rectangular parallelepiped structure, the sound absorption monomer is hollow structure, and the sound absorption monomer is internally formed continuous, curved
Bent channel of acoustic wave, the side of the channel of acoustic wave correspondence sound source is provided with acoustic wave inlet, and the sound absorber is existed by some sound absorption monomers
On in-plane matrix form split formed, the direction of the acoustic wave inlet of each sound absorption monomer it is consistent.
As it is of the invention a kind of preferred embodiment, inside the sound absorption monomer by it is parallel, be spaced, be staggered
The dividing plate formation continuous channel of acoustic wave of S-shaped.
As another preferred embodiment of the present invention, spiral is formed by helical baffle plates inside the sound absorption monomer
The annular channel of acoustic wave of shape.
As another preferred embodiment of the present invention, filling sucting sound material in the channel of acoustic wave.
As the further improvement to above-mentioned embodiment, the sound-absorbing material is rock wool, melamine foamed cotton, glass
Cotton or melamine cotton.
Beneficial effect
In the present invention, the single radial cut labyrinth type channel of acoustic wave knot by continuous bend is designed to inside the monomer that absorbs sound is passed through
Structure, the frequency range of sound absorption is controlled by the length of channel of acoustic wave, and passage is lengthened, and sound absorption frequency range is moved to low frequency, for low-frequency sound wave
With good assimilation effect.This structure frequency band is absorbed sound play a major role be channel of acoustic wave length, therefore this hair
Bright thickness can accomplish very thin, and substantially increasing should scope.

Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
A kind of spatial extent efficient plane sound absorber as shown in Figure 1, includes the sound absorption monomer 1 of rectangular parallelepiped structure, such as Fig. 2
It is shown.Sound absorption monomer 1 can be made according to specifically used occasion using common materials such as metal, cement, gypsum, plastics.
Sound absorption monomer 1 is hollow structure, sound absorption monomer 1 be internally formed continuously, the channel of acoustic wave 101 of bending, sound wave is logical
The side of the correspondence sound source of road 101 is provided with acoustic wave inlet 102, and the sound absorber is by some matrix forms in the in-plane direction of monomers 1 that absorb sound
Split is formed, the direction of the acoustic wave inlet 102 of each sound absorption monomer 1 is consistent.
Such as embodiments 1 of the Fig. 3 for the structure of sound absorption monomer 1 inside channel of acoustic wave 101, inside sound absorption monomer 1 by it is parallel,
Every, the dividing plate 103 that the is staggered formation continuous channel of acoustic wave 101 of S-shaped.
Such as embodiments 2 of the Fig. 4 for the structure of 1 inside channel of acoustic wave of sound absorption monomer 101, helical form is passed through inside the monomer 1 that absorbs sound
Dividing plate forms spiral helicine annular channel of acoustic wave 101.
Filling porous sound-absorbing material in channel of acoustic wave 101, forms double absorption, strengthens the effect absorbed to audio frequency.Inhale
Sound material is rock wool, melamine foamed cotton, mineral wool or melamine cotton.
By the structure of single radial cut labyrinth type channel of acoustic wave 101 by continuous bend is designed to inside the monomer 1 that absorbs sound, pass through sound
The frequency range of the length control sound absorption of ripple passage 101, passage is lengthened, and sound absorption frequency range is moved to low frequency, is had for low-frequency sound wave good
Good assimilation effect.This structure frequency band is absorbed sound play a major role be channel of acoustic wave 101 length, therefore the present invention
Thickness can accomplish very thin, and substantially increasing should scope.
