Abstract
This practicality provides a kind of bass trap of mini singing pavilion, including：One curved panel, it is separately connected one first backboard and one second backboard at left and right sides of the curved panel, both sides are separately connected a fixation top plate and a fixation bottom plate to the curved panel up and down, and a noise reduction operatic tunes is collectively formed in the curved panel, first backboard, second backboard, the fixed top plate and the fixed bottom plate；The curved panel is equipped with multiple sound-absorption holes, and polyester fiber acoustical cotton is filled in the noise reduction operatic tunes.Low-frequency sound wave is absorbed by sound-absorption hole guiding in the noise reduction operatic tunes, it is received immediately by the gap of polyester fiber acoustical cotton, sound wave collision is generated in minimum space to generate heat and volatilize, arc panel can be in greater area of absorption room while low-frequency sound wave, energy centering high frequency sound wave carries out comprehensive reflection and diffusing reflection, so that medium-high frequency sound wave multi-angle is spread, is effectively improved low frequency response, standing wave is eliminated, keeps sound apparent.
Description
Technical field
The utility model is related to a kind of sound-absorbing structure, the bass trap of espespecially a kind of mini singing pavilion.
Background technology
Mini singing pavilion bass trap is the important component that acoustic environment is built in mini singing pavilion, due to mini singing pavilion
Spatial area is small, sound field is chaotic, will produce standing wave and microphone and the problems such as utters long and high-pitched sounds.Based on this, it is necessary to be directed to mini singing
The existing technological deficiency of pavilion provides a kind of mini dedicated bass trap of singing pavilion, can effectively improve low frequency response, elimination is stayed
Wave, it is necessary to keep sound apparent.
Invention content
For background technology problem encountered, the purpose of this utility model is to provide a kind of improvement low frequency response and disappear
Except the bass trap of the mini singing pavilion of standing wave.
To achieve the above object, the utility model uses a kind of bass trap of mini singing pavilion of following technological means, packet
It includes：One curved panel, the curved panel left and right sides are separately connected one first backboard and one second backboard, the curved panel
Upper and lower both sides are separately connected a fixation top plate and one fixes bottom plate, the curved panel, first backboard, second back of the body
A noise reduction operatic tunes is collectively formed in plate, the fixed top plate and the fixed bottom plate；The curved panel is equipped with multiple sound-absorbings
Hole, the noise reduction operatic tunes is interior to fill polyester fiber acoustical cotton.
Further, the noise reduction operatic tunes is in triangle cambered surface solid tubular structure.
Further, the polyester fiber of the polyester fiber acoustical cotton containing 80%-85%.
Further, multiple laminates are equipped in the noise reduction operatic tunes.
Further, the extending direction of the laminate is vertical with the upper and lower directions of the curved panel.
Further, the sound-absorption hole extends along the upper and lower directions of the curved panel.
Further, the fixed bottom plate and/or the fixed top plate are equipped with multiple fixed screw holes positions.
Further, a gap is equipped between first backboard and second backboard.
Compared with prior art, the utility model has the advantages that：Low-frequency sound wave is guided by sound-absorption hole to be absorbed
It into the noise reduction operatic tunes, is received immediately by the gap of polyester fiber acoustical cotton, sound wave collision is generated in minimum space and is generated
Heat simultaneously volatilizees, arc panel can in greater area of absorption room while low-frequency sound wave, can centering high frequency sound wave carry out it is complete
The reflection and diffusing reflection in orientation make medium-high frequency sound wave multi-angle spread, and are effectively improved low frequency response, eliminate standing wave, make sound more
Clearly.

Specific implementation mode
It is in conjunction with attached drawing and specifically real for ease of being better understood from the purpose, structure, characteristics and efficacy of the utility model
Applying mode, the utility model is described in further detail.
As shown in attached Fig. 1 to Fig. 4, the bass trap of the mini singing pavilion of the utility model, including：One curved panel 1, institute
It states 1 left and right sides of curved panel and is separately connected one first backboard 2 and one second backboard 3, about 1 both sides of curved panel difference
Connection one fixes top plate 4 and one and fixes bottom plate 5, the curved panel 1, first backboard 2, second backboard 3, described solid
Determine top plate 4 and a noise reduction operatic tunes 6 is collectively formed in the fixed bottom plate 5；The curved panel 1 is equipped with multiple sound-absorption holes 7, institute
State filling polyester fiber acoustical cotton 8 in the noise reduction operatic tunes 6.
Further, the noise reduction operatic tunes 6 is in triangle cambered surface solid tubular structure, inside filling polyester fiber acoustical cotton 8.
Further, the polyester fiber of the polyester fiber acoustical cotton 8 containing 80%-85%.
Further, multiple laminates 9 are equipped in the noise reduction operatic tunes 6 so that the noise reduction operatic tunes 6 is unlikely to deform and adds
Gu its appearance.
Further, the extending direction of the laminate 9 is vertical with the upper and lower directions of the curved panel 1.
Further, the sound-absorption hole 7 extends along the upper and lower directions of the curved panel 1, and the sound-absorption hole 7 is with upper
The level for stating laminate 9 forms different sequences, the arrangement that formation one creates an aesthetic feeling and sound-absorbing effect is good.
Further, the fixed bottom plate 5 and/or the fixed top plate 4 are equipped with multiple fixed screw holes positions 10, will be described
The bass trap of mini singing pavilion is fixed on wall.The bass trap needs of the mini singing pavilion are fixed on by the ground in corner
