[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The limiting frame 5 contacts the loudspeaker cover 1. A handle 11 is fixedly connected to the outside of the connecting plate 8. The handle 11 can drive the connecting plate 8 to move. One end of the spring 10 is fixedly connected to the loudspeaker cover 1, and the other end of the spring 10 is fixedly connected to the connecting nail 7. The spring 10 can drive the connecting nail 7 to automatically reset through elastic force. The limiting post 9 is slidably connected to the loudspeaker cover 1 and slidably connected to the connecting seat 4. The limiting post 9 can limit the connecting seat 4.

[0024] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6The connecting mechanism 6 includes a fixed frame 61. Two symmetrically distributed fixed frames 61 are fixedly connected to the outside of the speaker 2. Two symmetrically distributed flip frames 62 are hinged to the upper outside of the speaker cover 1. A limit block 63 is fixedly connected to one end of the flip frame 62 near the speaker cover 1. A second spring 64 is provided inside the flip frame 62. The flip frame 62 can drive the limit block 63 to flip. The limit block 63 is engaged with the fixed frame 61.
