Specific implementation mode
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the two-dimentional male-type photonic crystal structure of the invention with microperforated panel, including substrate 1,
Substrate 1 is the square that the length of side is 50mm, and the substrate 1 is equipped with circular clad 3, and 3 internal diameter of clad is 10mm, thick
Degree is 10mm, and material is rubber, and becket 5, cavity thickness 8mm, preferably aluminium ring, gold are installed in the cavity in clad 3
Belonging to the microperforated panel 2 being equipped in ring 5 at least there are two through-hole, a diameter of 0.5mm of through-hole, 2 thickness of microperforated panel is 1mm,
Clad 3 is equipped with oscillator 4, and oscillator 4 is circular platy structure, and oscillator 4 can be adhesive on clad 3 by glue.
In the present invention, concrete structure is to introduce perforated microstructure on male-type two-dimension phonon crystal structure, described
The protrusion of structure is rubber adhesive 3 and oscillator 4, and using the structure of internal cavities inside rubber adhesive 3, internal empty
The outer layer of chamber has attached one layer of aluminium ring, microperforated panel 2 is added in 3 cavity of clad, cavity can be as the back of microperforated panel 2
Cavity.As shown in figure 4, bigger than the oise insulation factor of single layer steel plate in the Frequency section oise insulation factor that frequency is 100-500Hz or so
Very much, and also there is bigger sound insulation peak value, in conjunction with the analysis to unit cell band gap properties and characteristics of mode, it is possible to understand that
It is the frequency band there are band gap, band gap causes oise insulation factor to increase, and frequency continues to increase, the steel plate phase of oise insulation factor and thickness of the same race
Than oise insulation factor is still relatively good.
With the increase of 4 density of oscillator, the initial frequency and cutoff frequency of first band gap reduce, and band gap width is bright
Aobvious to increase, the density for increasing oscillator 4 is conducive to improve the low bandgap of male-type photonic crystal structure, and then increases harden structure and exist
The oise insulation factor of low frequency.With the increase of 3 density of clad, the initial frequency and cutoff frequency of first band gap reduce, but band gap
Width is obviously reduced；With the increase of filling rate, the increase of the not cut-off frequency of initial frequency increase tendency of first band gap becomes
Gesture is apparent, but band gap width increases obviously.Increase the thickness of clad 3 and the hollow-core construction using clad 3, drop can be reached
The purpose of low first band gap frequency, and the hollow-core construction of clad 3, and can be as the back cavity of microperforated panel 2, Jin Erke
Increase the oise insulation factor of other frequency ranges, also, the frequency of perforated microstructure role with the sound absorption characteristics using perforated microstructure
Section is can be reached by designing its structural parameters.It insulates against sound curve to the improved structure for only having hollow-core construction to be not added with micropunch
Therefore analysis, passes through it is recognised that sound insulation low ebb most the underlying cause is caused to be the noise of plate radiation and constructs internal micropunch
Structure can the noise of appropriate baffle radiation targetedly set in conjunction with male-type phonon crystal low frequency forbidden band characteristic itself
Count 3 radius of clad, 3 height of clad, the quality of hollow radius and oscillator 4, so that it may be put forward simultaneously to different frequency sections to realize
The effect of high oise insulation factor.
