Referring to fig. 1 and 2, the present invention provides a sound-proof cassette, including a first housing 10 and a second housing 20 stacked with the first housing 10; a damping sealing assembly 30 is arranged between the first shell 10 and the second shell 20, an installation cavity 210 is arranged on one side of the second shell 20 far away from the first shell 10, the threading pipe 40 is connected with the first shell 10 and communicated with the installation cavity 210, and an electric wire 410 led out from the threading pipe 40 extends into the installation cavity 210 for connecting an electric appliance; the damping seal assembly 30 is used to seal the installation cavity 210 and the threading tube 40, so that sound generated in the installation cavity 210 cannot be transmitted along the threading tube 40. That is, the sound emitted from the room of the partition wall on the side corresponding to the outlet side of the installation chamber 210 of the sound insulation cassette cannot be transmitted to other rooms through the installation chamber 210 and the threading pipe 40.

The damping sealing assembly 30 is arranged between the first shell 10 and the second shell 20, so that sound emitted from the installation cavity 210 cannot be transmitted through the threading pipe 40, the sound transmission in the cassette is blocked, the sound insulation performance of the light wall is improved, the construction complexity is not increased, and more adverse damage to the wall is not caused. For example, the sound generated by the socket hole and the electrical appliance will not be transmitted into the conduit 40 through the installation cavity 210. In one embodiment of the utility model, the cassette is used for lightweight walls such as keel-gypsum plasterboard partitions, keel-calcium silicate boards and walls having a mass per unit area of less than 90 kg/m. In other embodiments, the composite structure of the first housing 10, the damping seal assembly 30 and the second housing 20 may be provided for sound insulation as long as the sound insulation is required for the wall, and is not limited herein.

The damping seal assembly 30 includes a first seal 310 and a second seal 320, the first seal 310 is disposed between the first housing 10 and the second housing 20, and the second seal 320 is disposed between the first housing 10 and the second housing 20 and partially extends into the conduit 40. The first casing 10 and the second casing 20 can be sealed by the first sealing member 310, and the second sealing member 320 partially extends into the threading tube 40, and forms a seal between the installation cavity 210 and the threading tube 40, so that the sound generated through the installation cavity 210 can be isolated. And the second shell 20 and the first shell 10 are arranged in a stacked mode, so that too much installation space is not occupied, the installation is convenient and fast, and the disassembly is simple.

The first housing 10 is provided with a first mounting hole 110, and the second housing 20 is provided with a second mounting hole 220 corresponding to the first mounting hole 110; one end of the threading pipe 40 passes through the first mounting hole 110 and the second mounting hole 220 in sequence and is flush with one end surface of the second housing 20 close to the mounting cavity 210. The conduit 40 is used to introduce the electric wire 410 into the installation cavity 210, so that an electric appliance such as a socket installed outside the installation cavity 210 can be powered on. In an embodiment of the present invention, one end of the threading tube 40 is flush with the inner side surface of the second housing 20 close to the installation cavity 210, so that the space in the installation cavity 210 is not occupied, the overall size of the first housing 10 and the second housing 20 can be saved, the size of the whole device is smaller, and the damage to the wall can be minimized.
