Description
Technical field
The present invention relates to the sound absorption structure of a kind of photosensitive resin material, belong to noise control technique field.
Background technology
In noise control engineering, the sound absorption material and structure kind of application is a lot, is broadly divided into by its sound absorption principle
Porous sound-absorbing material and resonance sound-absorbing material.Such as foamed aluminium and foam copper etc. broadly fall into porous sound-absorbing material, and thin plate
Resonance sound-absorbing structure, thin film resonance sound-absorbing structure, perforated plate resonance sound-absorbing broadly fall into resonance sound-absorbing material.And in recent years about making an uproar
The research of sound deepens continuously, the broader field by the application extension of resonance sound-absorbing structure.Although perforated plate resonance sound-absorbing is tied
Structure and microperforated panel soundabsorbing construction have many excellent compared with porous sound-absorbing material at sound absorption characteristics, flow resistance, the aspect such as corrosion-resistant
More feature, but still cannot meet some noise control being actually needed, particularly in the field that sound absorption space is severely limited
Under conjunction, low-frequency noise to be controlled will manifest deficiency, will strengthen its Low Frequency Sound Absorption, is necessary for being significantly increased cavity depth, and
This cannot accomplish in Practical Project often.
China Patent Publication No. is that CN104882138A is disclosed " sound absorption structure of porous foam carborundum sound-absorbing material ",
Its structure utilizes the foam silicon carbon material sound absorption principle of " stacking " structure, increases its acoustic absorptivity and acoustic resistance, improves low frequency and inhale
Sound effective value.But in terms of processing, the machining property of carborundum is poor, it is impossible to meet machining needs.And carborundum
Granular size be also most important in terms of sound absorption, as fruit granule is excessive, its sound absorbing capabilities can be affected very big, be greatly reduced
Sound absorbing capabilities, if therefore wanting to ensure, preferable sound absorbing capabilities must use tiny " cystose " granule, its machining accuracy,
Tradition processing industry is difficulty with, and is unfavorable for promoting the use of of this structure, it addition, this structure of disclosed sound absorption can not be abundant
The sound absorption characteristics utilizing lumen coupled resonance carry out sound energy consumption.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of sound absorption structure, simple in construction, uses photosensitive resin 3D to print
Molding, it is not necessary to machining, the sound absorption characteristics that simultaneously can make full use of lumen coupled resonance are carried out sound energy consumption, are improved sound absorption effect
Really.
It is an object of the invention to be achieved through the following technical solutions:
The sound absorption structure of a kind of photosensitive resin material, including splitter and base plate, splitter array is arranged in a wherein surface of base plate
On, described base plate and splitter use photosensitive resin integral type 3D printing shaping, be provided with perforation, set inside splitter on base plate
Being equipped with splitter cavity, splitter cavity is corresponding with perforation, is provided with microperforated panel on another surface of base plate.
A diameter of 0.1 ~ 0.8mm of micropore on described microperforated panel, the punching rate of microperforated panel is 0.3 ~ 0.5%.
The thickness of base plate is 5 ~ 10mm, and the height of splitter is 40 ~ 50mm, and the axis of splitter is perpendicular to the surface of base plate.
A diameter of 1 ~ 6mm of described perforation, the diameter of splitter cavity oral area matches with the diameter of perforation.
Compared with prior art, beneficial effects of the present invention is as follows:
1, the present invention uses the compound sound-absorption structural of base plate+splitter, and total has used the principle of impedance matching, and splitter is used for
Realizing effective transmission of low-frequency range sound wave, base is used for effectively consuming being transmitted to its interior sound wave.It addition, arrange on base plate
Microperforated panel together form lumen coupled resonance structure with the perforation on base plate, splitter cavity, make use of tube chamber coupling well
The sound absorption characteristics amounting to shake carry out sound energy consumption, further increase acoustically effective.
2, in the present invention, base plate and splitter use photosensitive resin integral type 3D printing shaping, it is not necessary to machining, overcome
Using Conventional silicon carbide material to add the defect of difficulty, promoting the use of of sound absorption structure the most of the present invention, meanwhile, photosensitive resin has
Good low frequency absorption performance.
