Under the connection between the connecting rods 21 and the sliding rods 22, the protective cover 2 can slide along the surface of the slide groove 23 and ensure that it is not separated from the loudspeaker.

[0029] Furthermore, two groups of mounting rods 24 are provided, and the two groups of mounting rods 24 are fixedly connected to both sides of the upper housing 11. One end of the T-slot 25 is opened on the surface of the upper housing 11, and the other end of the T-slot 25 is opened inside the mounting rod 24. Under the action of the mounting rod 24, the protective cover 2 can be moved along the T-slot 25 to the other side of the upper housing 11 for placement, making it more convenient during use.

[0030] Furthermore, a rotating groove is opened at both ends of the rotating rod 28, and both ends of the rotating shaft 27 are rotatably connected to the surface of the rotating groove.

[0031] Furthermore, a quick-release mechanism is provided on the surface of the mounting shell 13, and the quick-release mechanism includes a mounting block 3, which is fixedly connected to the inner surface of the lower housing 1. A limiting groove 31 is provided inside the mounting block 3, and a support spring 32 is fixedly connected to the surface of the limiting groove 31. A limiting plate 33 is installed on the surface of the limiting groove 31, and a hemispherical block 34 is fixedly connected to the surface of the limiting plate 33. A through hole 35 is provided on the surface of the mounting shell 13.

[0034] Working principle: When using the loudspeaker, first slide the protective cover 2 along the surface of the upper housing 11. At this time, the connecting rod 21 and the sliding rod 22 also slide on the surface of the slide groove 23. When moving to the installation rod 24, the protective cover 2 rotates around the sliding rod 22, so that the protective cover 2 rotates to the side of the upper housing 11. At the same time, the connecting rod 21 and the sliding rod 22 slide along the surface of the T-slot 25. When sliding to the top of the T-slot 25, the rotating rod 28 is rotated so that the rotating rod 28 engages with the surface of the limiting rod 29, thereby limiting the protective cover 2.

[0035] When installing the mounting shell 13, first place the mounting shell 13 in the middle of the four groups of mounting blocks 3, and press the inner surface of the lower housing 1 at the same time, so that the hemispherical block 34 is squeezed and moves into the limiting groove 31.
