Designable combined hole sound absorption material
The invention discloses a designable combined hole sound absorption material. The material comprises a plate body, wherein a cavity used in cooperation with the plate body is formed in the rear face of the plate body, wave-shaped sound absorption holes, gourd-shaped sound absorption holes and hexagonal sound absorption holes are sequentially and alternately formed in the plate body from left to right, sound inlet holes used in cooperation with the wave-shaped sound absorption holes, the gourd-shaped sound absorption holes and the hexagonal sound absorption holes are formed in the front face of the plate body, sound outlet holes used in cooperation with the wave-shaped sound absorption holes, the gourd-shaped sound absorption holes and the hexagonal sound absorption holes are formed in the rear face of the plate body, transition holes communicating with the sound outlet holes are formed in the front face of the cavity, an inserting block is arranged on one side of the outer portion of the cavity, and an inserting hole used in cooperation with the inserting block is formed in the other side of the outer portion of the cavity. Compared with the prior art, the sound absorption device has the advantages of being good in sound absorption effect and convenient in use.
本发明公开了一种可设计的组合孔吸声材料，包括板体，所述板体的后面设有配合其使用的腔体，所述板体内部从左至右依次交替设有波浪形吸声孔、葫芦形吸声孔和六边形吸声孔，所述板体的前面设有配合波浪形吸声孔、葫芦形吸声孔和六边形吸声孔使用的进声孔，所述板体的后面设有配合波浪形吸声孔、葫芦形吸声孔和六边形吸声孔使用的出声孔，所述腔体的前面设有与出声孔相通的过渡孔，所述腔体的外部一侧设有插接块，所述腔体外部的另一侧设有配合插接块使用的插接孔。本发明与现有技术相比的优点在于：吸声效果好、便于使用。
