Abstract
The invention discloses a kind of efficient acoustic materials, including internal layer and outer layer, the internal layer is arranged in outer top, it is provided with sound absorbing layer between the internal layer and outer layer, it is both provided with vacuum chamber at the top and bottom of the sound absorbing layer, the vacuum chamber is provided with resonating membrane, and the sound absorbing layer is internally provided with reinforced sheet.The present invention is by being arranged vacuum chamber, resonating membrane and sound absorbing layer, sound first passes around vacuum chamber, vacuum chamber can greatly obstruct the transmission of sound, and the sound entered after vacuum chamber can generate resonance to the resonating membrane made of tinfoil, weaken the intensity of sound, it eventually enters into the sound absorbing layer being made of a foam material to be obstructed by it, can be good at playing sound-absorbing effect, be conducive to improve soundproof effect.
Description
Technical field
The present invention relates to acoustic material technical field, more particularly to a kind of efficient acoustic material.
Background technology
With the development of the modern industry, environmental pollution is also with generation, and noise pollution is exactly one kind of environmental pollution,
As the big harm to the mankind.Noise pollution is regarded as three main environments in world wide with water pollution, atmosphere pollution
Problem.The acoustic material of the prior art is simple in structure, is often made of the compound felt rug of acoustic material, soundproof effect is poor, urgently
It is to be modified.
Therefore, it is necessary to solve the above problems to invent a kind of efficient acoustic material.
Invention content
The purpose of the present invention is to provide a kind of efficient acoustic materials, pass through vacuum chamber, resonating membrane and sound absorbing layer, vacuum chamber
The transmission that sound can greatly be obstructed can generate resonance to the resonating membrane made of tinfoil into the sound after vacuum chamber, cut
The weak intensity of sound, the sound absorbing layer being made of a foam material are obstructed by it, can be good at playing sound-absorbing effect, in solution
State the problem of being proposed in background technology.
To achieve the above object, the present invention provides the following technical solutions：A kind of efficient acoustic material, including internal layer and outer
Layer, the internal layer setting are provided with sound absorbing layer, the sound absorbing layer top and bottom between outer top, the internal layer and outer layer
It is both provided with vacuum chamber, the vacuum chamber is provided with resonating membrane, and the sound absorbing layer is internally provided with reinforced sheet.
Preferably, the sound absorbing layer is made of a foam material.
Preferably, the resonating membrane is set as tinfoil.
Preferably, the reinforced sheet is made of Steel material.
Beneficial effects of the present invention are：Vacuum chamber is first passed around by the way that vacuum chamber, resonating membrane and sound absorbing layer, sound is arranged,
Vacuum chamber can greatly obstruct the transmission of sound, and the sound entered after vacuum chamber can produce the resonating membrane made of tinfoil
Raw resonance, weakens the intensity of sound, eventually enters into the sound absorbing layer being made of a foam material and obstructed by it, can be good at playing
Sound-absorbing effect is conducive to improve soundproof effect.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
In figure：1 internal layer, 2 outer layers, 3 sound absorbing layers, 4 vacuum chambers, 5 resonating membranes, 6 reinforced sheets.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of efficient acoustic materials as shown in Figure 1, including internal layer 1 and outer layer 2, the internal layer 1 to set
It sets at 2 top of outer layer, sound absorbing layer 3 is provided between the internal layer 1 and outer layer 2,3 top and bottom of the sound absorbing layer are both provided with
Vacuum chamber 4, the vacuum chamber 4 are internally provided with resonating membrane 5, and the sound absorbing layer 3 is internally provided with reinforced sheet 6.
Further, in the above-mentioned technical solutions, the sound absorbing layer 3 is made of a foam material, and is made of a foam material
Sound absorbing layer 3 can be to sound barrier；
Further, in the above-mentioned technical solutions, the resonating membrane 5 is set as tinfoil, into the sound energy after vacuum chamber 4
It is enough that resonance is generated to the resonating membrane 5 made of tinfoil, weaken the intensity of sound；
Further, in the above-mentioned technical solutions, the reinforced sheet 6 is made of Steel material, reinforces made of Steel material
Piece 6 can improve whole stability.
Operation principle of the present invention：
With reference to Figure of description 1, sound-absorbing material is in use, the sound entered from internal layer 1 or from outer layer 2 first passes around vacuum
Chamber 4, vacuum chamber 4 can greatly obstruct the transmission of sound, and entering the sound after vacuum chamber 4 can be to total made of tinfoil
Vibrating diaphragm 5 generates resonance, weakens the intensity of sound, eventually enters into the sound absorbing layer 3 being made of a foam material and obstructed by it, can be very
Good plays sound-absorbing effect, is conducive to improve soundproof effect, the reinforced sheet 6 made of Steel material can improve whole consolidate
Property.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
