Abstract
The present invention relates to a kind of green muffler plate, sound attenuation hole is provided with the muffler plate body, the noise elimination hole number is 24, it is in 4*6 matrix distributions on the muffler plate body, the rounded hole of sound attenuation hole, sound attenuation hole is connected with noise elimination capsule, and the noise elimination capsule is in truncated rectangular pyramids shape cavity, the trapezoidal structure in noise elimination capsule section.The noise elimination capsule section is in isosceles trapezoidal structure.The muffler plate of the present invention, by setting some noise elimination pore structures on plate body surface, pass through the up-narrow and down-wide structure setting unique with noise elimination capsule of sound attenuation hole so that after sound enters the noise elimination capsule inside muffler plate outside muffler plate by sound attenuation hole, it is difficult to spill, to take the effect of noise elimination.
Description
Technical field
The present invention is more particularly directed to a kind of green muffler plate.
Background technology
The one kind of acoustical panel as modern architecture industry building material, for absorbing sound, main function is to be used for interior
Noise reduction, reverberation time etc. is reduced, make indoor sound more clear-cut, limpid, not muddy.Current acoustical panel mostly using acoustical cotton or
Person's sound-absorbing material is compounded in outside plate body, for abatvoix plate body structure without too big change, because sound-absorbing material may produce
Raw odor contamination, therefore, researches and develops a kind of structure class muffler plate and also has been to be concerned by more and more people.
The content of the invention
The present invention proposes a kind of green muffler plate regarding to the issue above.
Specific technical scheme is as follows：
A kind of green muffler plate, it is characterised in that including muffler plate body, noise elimination is provided with the muffler plate body
Hole, the noise elimination hole number are 24, are in 4*6 matrix distributions on the muffler plate body, the rounded hole of sound attenuation hole, disappear
Acoustic aperture is connected with noise elimination capsule, and the noise elimination capsule is in truncated rectangular pyramids shape cavity, the trapezoidal structure in noise elimination capsule section.
A kind of green muffler plate, it is characterised in that the noise elimination capsule section is in isosceles trapezoidal structure.
Beneficial effects of the present invention are：
The muffler plate of the present invention, it is only by sound attenuation hole and noise elimination capsule by setting some noise elimination pore structures on plate body surface
Special up-narrow and down-wide structure setting so that after sound enters the noise elimination capsule inside muffler plate outside muffler plate by sound attenuation hole,
It is difficult to spill, to take the effect of noise elimination.
Brief description of the drawings
Fig. 1 is sectional view of the present invention.
Fig. 2 is top view of the present invention.
Embodiment
To make technical scheme become apparent from clearly, the present invention is described further below in conjunction with the accompanying drawings,
Any scheme drawn to the technical characteristic progress equivalencing of technical solution of the present invention and conventional reasoning each falls within guarantor of the present invention
Protect scope.
Description of reference numerals
Muffler plate plate body 1, sound attenuation hole 2, noise elimination capsule 3.
A kind of green muffler plate, it is characterised in that including muffler plate body, be provided with and disappear on the muffler plate body
Acoustic aperture, the noise elimination hole number are 24, are in 4*6 matrix distributions on the muffler plate body, the rounded hole of sound attenuation hole,
Sound attenuation hole is connected with noise elimination capsule, and the noise elimination capsule is in truncated rectangular pyramids shape cavity, the trapezoidal structure in noise elimination capsule section.The noise elimination
Capsule section is in isosceles trapezoidal structure.
Beneficial effects of the present invention are：
The muffler plate of the present invention, it is only by sound attenuation hole and noise elimination capsule by setting some noise elimination pore structures on plate body surface
Special up-narrow and down-wide structure setting so that after sound enters the noise elimination capsule inside muffler plate outside muffler plate by sound attenuation hole,
It is difficult to spill, to take the effect of noise elimination.
