Abstract
The utility model discloses a kind of sound panel and sound attenuator, including interior plank layer, outer plank layer and the damping layer or/and sheet-metal layers being set between the interior plank layer and the outer plank layer.The utility model soundproof effect is good.
Description
【Technical field】
The utility model is related to a kind of audio units, relate more specifically to the noise reduction of a kind of sound panel and the application sound panel
Case.
【Background technology】
Sound attenuator be test product under certain acoustic environment, obtain the sound performance of test product, be product inspection
Sound insulation detection environment is provided.The sound panel of existing sound attenuator is generally single layer aluminium sheet or individual layer boarding, oise insulation factor are opposite
It is relatively low, especially show middle low frequency, less desirable after low frequency and 1000hz sections, resultant effect is only every the sound for having fallen 9.1db
Pressure.For the relatively low loud speaker test of low frequency sensitivity, signal-to-noise ratio is not high, so that the stability of properties of product test is not
It is high.
Therefore, it is necessary to provide a kind of novel sound attenuator.
【Utility model content】
The purpose of this utility model is to provide the noise reductions of a kind of good sound panel of soundproof effect and the application sound panel
Case.
The technical solution of the utility model is as follows：A kind of sound panel including interior plank layer, outer plank layer and is set to described
Damping layer or/and sheet-metal layers between interior plank layer and the outer plank layer.
Preferably, setting is bonded between the sheet-metal layers and the damping layer.
Preferably, the sound panel further comprises between the air being set between the sheet-metal layers and the damping layer
Interlayer.
Preferably, the thickness of the interior plank layer is 20mm-30mm.
Preferably, the thickness of the outer plank layer is 5mm-15mm.
Preferably, the thickness of the sheet-metal layers is 2mm-5mm.
The thickness of the damping layer is 4mm-8mm.
The hardness of the damping layer is 20-60 degree.
The another technical solution of the utility model is as follows：A kind of sound attenuator, the sound attenuator include roof, bottom wall and connect
The wall of roof and the bottom wall is connect, the wall is using the sound panel described in above-mentioned any one.
Compared with the relevant technologies, the advantageous effect of sound panel and sound attenuator provided by the utility model is：
The utility model by increasing damping layer or/and sheet-metal layers between inside and outside plank layer, so as to increase every
The soundproof effect of soundboard, while sound wave is caused to be not easy to resonate in internal procedure is transmitted into, and decay and increase again.
【Description of the drawings】
Fig. 1 is the exploded view of sound panel provided by the utility model；
Fig. 2 is the optical cable of sound attenuator shown in Fig. 1；
Fig. 3 is the enlarged drawing of the part-structure of sound attenuator shown in Fig. 2.
【Specific embodiment】
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the utility model some embodiments rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 3, in the utility model, a kind of sound panel 10 is disclosed, including interior plank layer 1, outer plank layer
2 and the damping layer 3 or/and sheet-metal layers 4 that are set between the interior plank layer 1 and the outer plank layer 2, in the present embodiment,
There is provided damping layer 3 and sheet-metal layers 4 simultaneously.Setting can be bonded between the sheet-metal layers 4 and the damping layer 3, also may be used
To be arranged at intervals, during interval setting, the sound panel 10 further comprises being set to the sheet-metal layers 4 and the damping layer 3
Between air space 5.The thickness of the interior plank layer 1 is 20mm-30mm, and the thickness of the outer plank layer 2 is 5mm-
15mm, the thickness of the sheet-metal layers 4 are 2mm-5mm, and the thickness of the damping layer 3 is 4mm-8mm, the damping layer 3 it is hard
It spends for 20-60 degree.The utility model is preferred, the interior plank layer 1 be 25mm, the outer plank layer 2 be 10mm, the damping
Layer 3 is 6mm, and the sheet-metal layers 4 are 3mm.
It is interior plank layer 1, damping layer 3, sheet-metal layers 4, outer plank layer 2 successively from inside to outside, wherein hindering in the present embodiment
Buddhist nun's layer 3 and the position of sheet-metal layers 4 can be interchanged.
Damping layer 3 can be that damping material is filled between being its adjacent two layers, form damping layer 3 or elder generation
Damping layer 3 is molded into plate, then is bonded with other layers, damping material can be expanded material, such as sponge or poly-
Benzene foaming, polyethylene foam etc..Sheet-metal layers can be aluminium sheet, steel plate, copper coin etc..
As shown in Fig. 2, the utility model discloses a kind of sound attenuator 100, the sound attenuator 100 include roof (not shown),
The wall 102 of bottom wall 101 and connection roof and the bottom wall 101, the wall 102 are made of above-mentioned sound panel 10.Compared to
The structure of same thickness individual layer plank, the double-deck plank of wall application of the sound attenuator of the utility model add the knot of damping layer, sheet-metal layers
Structure may be such that oise insulation factor increases at least 10db or so more；The different medium of central filler damping layer and sheet-metal layers so that sound wave
It is not easy to resonate in internal procedure is transmitted into, and sound wave of decaying.
Above-described is only the embodiment of the utility model, it should be noted here that the ordinary skill for this field
For personnel, under the premise of not departing from the utility model and creating design, improvement can also be made, but these belong to this practicality
Novel protection domain.
