Description

Technical Field

[0001] The utility model relates to the technical field of acoustic wedges, in particular to a fixing and disassembling device for acoustic wedges. Background Technique

[0002] An acoustic wedge is a special sound absorber, which requires that the sound waves incident on its surface are almost completely absorbed. The acoustic wedge consists of a base part and a wedge part. The base part is the part with an unchanged bottom cross-section, and the wedge part is the part with a gradually increasing cross-section starting from the tip. Since the cross-section of the wedge part of the acoustic wedge gradually increases from small to large, it is more matched with the characteristic impedance of air, so that the incident sound waves are almost completely absorbed without reflection.

[0003] When the acoustic wedge is directly exposed and needs to be replaced after long-term use, the existing acoustic wedges for anechoic chambers are installed on the wall of the anechoic chamber through a connecting plate fixedly connected to its back during use. The installation and disassembly are difficult, which is not conducive to its maintenance. Content of the Utility Model
