Technical Field
The invention relates to the technical field of sound absorption materials, in particular to a designable combined hole sound absorption material.
Background
The perforated plate sound absorber is formed by perforating a thin plate, and a certain distance is kept between the perforated plate sound absorber and a wall when the perforated plate sound absorber is installed, so that a cavity is reserved behind the perforated plate sound absorber to form a resonant cavity type sound absorbing structure. Because the wavelength of the incident sound wave is far larger than the size of the small hole, after the incident sound wave enters the perforated plate, the air molecules in the perforation and the cavity generate vibration friction, and part of sound energy is consumed; when the frequency of the sound in the perforation is consistent with that of the sound in the cavity, violent resonance is generated, the sound wave overcomes the frictional resistance between the perforation and the inner surface of the cavity to do work, and then a large amount of sound energy is converted into heat to be dissipated, so that the purpose of sound absorption is achieved. When the sound absorption material in the prior art is used, the sound absorption effect is not good, the using effect is not good, the flexibility is low, and the sound absorption material is inconvenient to use.

Compared with the prior art, the invention has the advantages that: the designable combined hole sound absorption material can increase the contact area of sound waves and a plate body by utilizing the matching of the wave-shaped sound absorption holes, the gourd-shaped sound absorption holes and the hexagonal sound absorption holes, thereby achieving the purpose of sound absorption and improving the sound absorption effect; the matching of the transition hole and the cavity body can be utilized to carry out secondary sound absorption treatment on the sound waves after the sound absorption once, so that the sound absorption effect is improved; utilize the cooperation of grafting piece and spliced eye, can make a plurality of plate bodys combination use together, not only improved the use flexibility, easy operation moreover, labour saving and time saving, convenient to use.
As an improvement, the blocking blocks are alternately arranged inside the wavy sound absorption holes, the gourd-shaped sound absorption holes and the hexagonal sound absorption holes, so that sound and the blocking blocks can be fully rubbed to do work, a large amount of sound energy is consumed, and the purpose of sound absorption is achieved.
As an improvement, a blocking column matched with the transition hole for use is arranged behind the inner part of the cavity body, and the blocking column is of a hollow structure, so that sound and the blocking column can be fully rubbed to do work, a large amount of sound energy is consumed, and the purpose of sound absorption is achieved.
As an improvement, a sealing gasket matched with the inserting block for use is arranged in the inserting hole, so that a plurality of plate bodies can be tightly fixed together, sound can be prevented from being exposed, and the using effect is improved.
As an improvement, a silencing pad matched with the cavity is arranged behind the outer part of the cavity, so that the aim of sound absorption can be fulfilled.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A designable combined hole sound absorption material comprises a plate body 1, wherein a cavity 12 matched with the plate body 1 for use is arranged at the back of the plate body 1, a wave-shaped sound absorption hole 6, a gourd-shaped sound absorption hole 5 and a hexagon sound absorption hole 4 are sequentially and alternately arranged from left to right inside the plate body 1, a sound inlet hole 3 matched with the wave-shaped sound absorption hole 6, the gourd-shaped sound absorption hole 5 and the hexagon sound absorption hole 4 for use is arranged in front of the plate body 1, a sound outlet hole 10 matched with the wave-shaped sound absorption hole 6, the gourd-shaped sound absorption hole 5 and the hexagon sound absorption hole 4 for use is arranged at the back of the plate body 1, a transition hole 8 communicated with the sound outlet hole 10 is arranged in front of the cavity 12, an insertion block 7 is arranged at one side of the outside of the cavity 12, and an insertion hole 13 matched with the insertion block 7 for use is arranged at the other side of the outside of the cavity 12.
And blocking blocks 2 are alternately arranged inside the wave-shaped sound absorption holes 6, the gourd-shaped sound absorption holes 5 and the hexagonal sound absorption holes 4.
The rear surface of the inner part of the cavity 12 is provided with a blocking column 9 matched with the transition hole 8, and the blocking column 9 is of a hollow structure.
And a sealing gasket matched with the plug block 7 is arranged in the plug hole 13.
The rear surface of the outer part of the cavity 12 is provided with a silencing pad 11 matched with the cavity.
In the specific implementation of the invention, the structural schematic diagram of the designable combined hole sound absorption material shown in fig. 1 is combined, so that when the designable combined hole sound absorption material is used, sound waves firstly enter the wavy sound absorption holes 6, the gourd-shaped sound absorption holes 5 and the hexagonal sound absorption holes 4 through the sound inlet holes 3, and because of the different shapes of the wavy sound absorption holes 6, the gourd-shaped sound absorption holes 5 and the hexagonal sound absorption holes 4, the contact area of the sound waves and the plate body 1 can be increased, the purpose of sound absorption is achieved, and the sound absorption effect is improved. Because the blocking blocks 2 are alternately arranged inside the wavy sound absorption holes 6, the gourd-shaped sound absorption holes 5 and the hexagonal sound absorption holes 4, sound and the blocking blocks 2 can fully rub to do work, a large amount of sound energy is consumed, the purpose of sound absorption is achieved, and the sound absorption effect is improved. The sound waves processed once enter the cavity 12 through the sound outlet holes 10 and the transition holes 8, so that the contact area of the sound waves and the plate body 1 can be increased again, the purpose of sound absorption is achieved, and the sound absorption effect is improved. Because the blocking column 9 matched with the transition hole 8 for use is arranged behind the cavity 12, and the blocking column 9 is of a hollow structure, sound and the blocking column 9 can be fully rubbed to do work, a large amount of sound energy is consumed, the purpose of sound absorption is achieved, and the sound absorption effect is improved.
