Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing wedges, in particular to a mounting module for a sound-absorbing wedge. Background Art

[0002] A sound-absorbing wedge is a special sound-absorbing structure used in anechoic chambers. It is typically divided into a tip and a base. During installation, an air layer is left between the tip and the wall. From the tip to the base of the wedge, the acoustic impedance gradually transitions from the characteristic impedance of air to the impedance of the porous material, achieving excellent impedance matching and effectively absorbing incident sound energy.

[0003] Currently, sound-absorbing wedges are generally opposing modules, which are continuously spliced ​​and fixed during installation. However, once some independent modules are damaged after installation, they are difficult to disassemble independently and flexibly, which may cause damage to nearby sound-absorbing wedges, and replacement and assembly are not flexible enough.
