[0031] The technical advantages of this solution are as follows: This solution adopts a double sound-absorbing layer structure, which can effectively improve the sound absorption capacity of the ceiling. Specifically, a sound-absorbing channel 15 is set on the first sound-absorbing layer 11, which further enhances the sound absorption capacity.

[0032] The first sound-absorbing layer 11 and the second sound-absorbing layer 13 in this solution can be made of sound-absorbing cotton, fireproof sound-absorbing board, sound-absorbing foam board or other loose structural layers with sound-absorbing capabilities.

[0033] As one embodiment of this invention, the lower end of the silencing channel 15 extends through the lower end face of the first silencing layer 11.

[0034] Furthermore, the silencing channel 15 is wavy. The silencing channel 15, combined with the loose structure of the first silencing layer 11, can significantly improve the silencing capability.

[0035] Furthermore, there are multiple silencing channels 15.

[0036] As one embodiment of this invention, the first mounting plate 12 is provided with a sound-absorbing hole 16.

[0037] As one embodiment of this invention, the ceiling assembly includes:

[0038] Frame 17 is installed on the building structure via hangers 18;

[0039] The adjustment component has its upper end mounted on the frame 17 and its lower end fixed on the second mounting plate 14. The adjustment component is used to adjust the position of the second mounting plate 14.

[0040] The technical advantage of this solution is that by adjusting the position of the second mounting plate 14, the position of the first sound-absorbing layer 11 can be adjusted.

[0041] As one embodiment of this example, the frame 17 includes a horizontal square tube 19 and a vertical square tube 20, which are fixedly connected. The horizontal square tube 19 is used to install the adjustment component, and the vertical square tube 20 is used to install the hanger 18.
