[0023] The above-mentioned parts shell 1, speaker cover 2, speaker 3, PCBA circuit board 4 and bottom plate 5 are combined to form the ultra-thin subwoofer in the present technical solution. When in use, the assembled ultra-thin subwoofer is installed in the car audio system, so that voice broadcasting can be effectively performed in the interior space of the car when in use.

[0024] A partition plate 6 is installed on the inner wall of the speaker cover 2, one side of the partition plate 6 is integrally connected with a first side panel 7, the other side of the partition plate 6 is integrally connected with a second side panel 8, and a side strip 10 is connected to the outer wall of the partition plate 6 away from the speaker cover 2.

[0025] Preferably, the partition plate 6 is an arc-shaped structure, and the arc-shaped inner wall of the partition plate 6 is adapted to the curvature of the outer wall of the maximum outer diameter end of the speaker 3 .

[0026] During specific use, the arc-shaped end of the partition plate 6 contacts the arc-shaped outer wall of the upper end of the loudspeaker 3 during installation, so that the partition plate 6 can be normally installed on one side of the loudspeaker 3 .

[0027] Preferably, the speaker 3 and the PCBA circuit board 4 are mounted on the bottom plate 5 by screws, and both ends of the partition plate 6, the first side plate 7 and the second side plate 8 are in contact with the inner wall of the housing 1 and the surface of the bottom plate 5 respectively.
