Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, a kind of compoiste sound-absorbing board, including micropore acoustical panel layer 1 and rock wool layer 5, the both ends difference of rock wool layer 5
It is provided with upper end metal layer and lower end metal layer, upper end metal layer is provided with reinforcement supporting layer, and reinforces supporting layer and be entrained in
It holds between metal layer and micropore acoustical panel layer 1.The thickness of rock wool layer can be set according to actual needs, it may be preferable that rock wool
The thickness range of layer is set as being greater than or equal to 12mm less than or equal to 13mm.It is provided on micropore acoustical panel layer 1 and makes an uproar for weakening
The wave groove of sound and oblique geometry hole, noise can collide when by micropore acoustical panel layer 1 with its wave groove,
To cause the portion of energy of sound wave to lose, reach erasure effect.In the present embodiment, reinforcing supporting layer is honeycomb sandwich layer 3.
Further, it is additionally provided with the on-woven layer of cloth 2 with soundproof effect, on-woven layer of cloth 2 includes the first bonded fabric
Layer 21 and the second on-woven layer of cloth 22, are mingled with the first on-woven layer of cloth 21 between micropore acoustical panel layer 1 and honeycomb sandwich layer 3,
It is mingled with the second on-woven layer of cloth 22 between lower end metal layer and rock wool layer 5, and lower end metal layer and rock wool layer 5 pass through binder
The two is bonded.Fibrous web-like possessed by on-woven layer of cloth 2 itself, when noise transmission is to this layer, meeting and fibrous layer
Net collides, and during collision, energy conversion has occurred, sound is caused to be weakened.And honeycomb sandwich layer is with high-strength
The bearing capacity of degree, internal layer be special hexagonal honeycomb, receiving pressure can be played as being adhered in sandwich, dispersion or
Person undertakes from extraneous pressure, makes compoiste sound-absorbing board uniform force.
Further, metal layer material in upper end is aluminium sheet, alternatively, lower end metal layer material is aluminium sheet, alternatively, upper end metal
Layer and lower end metal layer material are aluminium sheet.Certainly, upper end metal layer is also possible to other metals with lower end metal layer and is made, excellent
Aluminium sheet first is used, manufacturing cost can be saved on the basis of improving compoiste sound-absorbing board integral strength and sound-absorbing effect.
In order to reach better sound-absorbing effect, noise bring adverse effect is reduced, offers linear battle array on aluminum layer 4
Arrange the through-hole of arrangement.Wherein, aluminum layer 4 includes the first aluminum layer 41 and the second aluminum layer 42, and noise is passing through the first aluminium
When plate layer 41, the first aluminum layer 41 is in contact with honeycomb sandwich layer 3, can form approximate closed confined space, prevent air stream
It is dynamic, it is hindered sound wave, improves sound-absorption coefficient.Followed by, noise after weakening, when by the first aluminum layer 41, battle array
The thickly dotted through-hole arranged is arranged, since sound wave is when passing through aperture, can be collided with the first aluminum layer 41, Neng Goujin
One step weakens the intensity of noise, achievees the effect that noise reduction again.In the present embodiment, the through-hole diameter on aluminum layer preferentially selects
For φ 3mm, the preferential selection range of aluminium plate thickness is to be less than or equal to 1mm more than or equal to 0.5mm.Cost can reduced in this way
While, additionally it is possible to improve sound-absorbing effect.
Further, the rock wool layer 5 of 41 lower end of the first aluminum layer can further absorb the noise after weakening, inhale
Audio fruit is close to be fully absorbed, and can solve noise caused by various frequencies easily.Rock wool material used by rock wool layer 5
Belong to sound-absorbing porous material, sound absorption principle is that there are many minim gaps in the material, thus have certain aeration, works as sound
Wave causes the vibration of air in aperture or gap when being incident on the inside, the air particle of small hole center be free to response sound wave
Compression with sparse, the air particle vibration velocity against hole wall or material surface is slower, due to rub and air viscid resistance
Power makes the kinetic energy of air particle constantly be converted into thermal energy.In addition, heat exchange also constantly occurs in aperture between air and hole wall,
These are all absorbed quite a few because being converted into thermal energy.Since sound can be absorbed or be converted to the energy of other forms
Amount, therefore sound-absorbing effect can be played, and sound-absorbing effect is very good.
Further, the lower end of rock wool layer 5 is bonded with the second on-woven layer of cloth 22, and the second on-woven layer of cloth 22 is rock wool layer
5 provide the confined space of a myopia sealing, can hinder the flowing of air, therefore energy loss can occur in aperture for sound, from
And rock wool layer 5 reaches better sound-absorbing effect.And then, the lower section of the second on-woven layer of cloth 22 is also correspondingly provided with erasure effect
Second aluminum layer 42, function are identical as 41 role of the first aluminum layer.The characteristic of metal can not be penetrated using electromagnetic wave, it is multiple
Closing abatvoix and can also playing certain prevents Electromagnetic Interference.
Compoiste sound-absorbing board combination: rock wool layer is carried out with the second on-woven layer of cloth by binder be bonded, and micropore disappears
Interlayer between soundboard and rock wool layer is using the connection type being layering.
Whole working principle are as follows: noise enters from the front of micropore acoustical panel layer 1, first by micropore acoustical panel layer 1
Wave groove receives, and absorbs a large amount of particle Impact energy, causes extrusion friction to lose because penetrating incident acoustic wave, then wear
The back side for crossing micropore acoustical panel layer 1 generates the viscid effect of particle by the oblique geometry hole that the back side is equipped in cavity resonance, will
Noise stops absorption；Noise after weakening is again via the layer of the first on-woven layer of cloth 21, honeycomb sandwich layer 3 and the first aluminum layer 41
Layer weakens, and remaining noise energy particle is penetrated into the rock wool layer 5 of lower layer again, and rock wool layer 5 absorbs surplus particle, into one
Step obtains good sound-absorbing effect, finally via the effect of the second on-woven layer of cloth 22 and the second aluminum layer 42, to reach
Superpower noise reduction effect.In addition, honeycomb core structures are added in the utility model, entire abatvoix uniform force can be made, strengthened
The integral strength of compoiste sound-absorbing board.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
