Embodiment Construction
[0120] In order to fully illustrate the technical solutions implemented and used by the present invention to solve the technical problems. The invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the technical solution, implementation of the technical solution and protection scope of the present invention are not limited thereto.
[0121] figure 1 It is a generalized structural schematic diagram of the acoustic material structure of the present invention attached to the surface of the acoustic radiation structure. The acoustic material structure is used to attach to the surface of the sound radiation structure 1, the acoustic material structure includes an acoustic unit, the acoustic unit has an opening 3, the opening 3 runs through the acoustic unit, and the acoustic unit includes a sheet 2. There is a cavity 4 between the sheet 2 and the sound radiation structure 1 , and the cavity 4 communicates with the opening 3 ....
