In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific implementation described herein is only used to explain this
Utility model is not used to limit the utility model.
The present invention is theoretical by using low frequency sound insulation high frequency sound-absorbing, and low-and high-frequency sound insulation drop is carried out using multiple sound insulation characteristic
It makes an uproar.Sound wave is propagated in air, and when inciding into homogeneous screen, part acoustic energy is reflected, and is partly absorbed, and also has part acoustic energy
Screen can be penetrated.Adequate shielding object is set acoustic energy can be prevented to penetrate, reduces sonic propagation of making an uproar, and enters therein make an uproar
Sound achievees the purpose that sound absorption by two ways.First, viscosity resistance consumes energy：When sound wave causes by material surface inside gap
During air vibration, relative motion is generated between air and solid channels and collaterals, since the viscosity of air generates corresponding viscosity resistance, is made
Vibration aerodynamic energy constantly transforms into thermal energy, so that acoustic wave energy is decayed.Second is that heat exchange is consumed energy：Sound wave by when occur
Air adiabatic compression heating, heat exchange and heat transfer with porous material reach acoustic energy attenuation with this.
As shown in Figure 1, the sound panel of one embodiment of the utility model includes porous plate 110 and substrate 120, porous plate 110
Sound insulation resonant cavity 130 is formed by being fixed on substrate 120.Multiple through holes 111 are offered on porous plate 110, through hole 111
Pitch-row and diameter are determined according to sound absorption resonant frequency, and the purpose of sqouynd absorption lowering noise is carried out with the noise met to different frequency.
Preferably, the aperture of the through hole 111 on porous plate is 3mm, pitch-row 6mm.Substrate 120 uses common plate, and it is preferable to use steel
Plate.In sound insulation resonant cavity 130 low density acoustic layer 140, high density are disposed with from porous plate 110 to 120 direction of substrate
Puigging 150 and high frequency sound absorbing layer 160 form the sound panel for being superimposed and being formed according to particular order by six layers of different materials, low
Density acoustic layer 140 and high density puigging 150 are while absorbing and completely cutting off low-frequency range noise to some high band noises
There is absorption insulating effect, high frequency sound absorbing layer 160 mainly absorbs and isolation high band noise simultaneously also there are some low-frequency range noises
Absorption and insulating effect.Sound panel in the present embodiment not only there is efficient absorb to completely cut off effect the noise of Low Medium Frequency section,
And also there is efficient absorb to completely cut off effect the noise of high band simultaneously, realize noise reduction purpose to greatest extent.
In the another embodiment of the utility model, buffer layer is additionally provided between high frequency sound absorbing layer 160 and substrate 120
170, buffer layer 170 is attached on substrate 120, is mainly used to reduce the vibration of sound panel so as to reduce making an uproar for sound insulation panel vibration generation
Sound, buffer layer 170 are ensureing the premise with good damping effect according to the relatively reasonable thickness of different material corresponding selections
Under, as far as possible mitigate sound panel entirety weight.
