When the speaker is not in use, the rotating seat 3 can be controlled to rotate, so that the sound module 4 rotates to the position corresponding to the inside of the fixed frame 1, so that the sound module 4 can be protected, and the sound module 4 is effectively prevented from being affected by the outside world and possibly damaged.

[0031] like Figure 2 and Figure 5As shown, the fixed back plate 9 is slidably connected to a sliding plate 10 inside; springs are fixedly connected between the top and bottom of the sliding plate 10 and the side walls of the fixed back plate 9; a wire outlet hole is opened inside the sliding plate 10, and a sealing ring 11 is installed at the position corresponding to the boundary of the wire outlet hole; during operation, when the speaker is installed, the connecting wire 8 of the rotating seat 3 can be passed through the wire outlet hole and led out from the top or bottom of the fixed frame 1, and during the rotation of the rotating seat 3, the connecting wire 8 will pull the sliding plate 10, so that the wire outlet hole will move with the connecting wire 8, effectively avoiding the connecting wire 8 from accumulating too much inside the fixed frame 1 after being pulled, which easily causes the connecting wire 8 to be entangled, knotted and broken, making the use of the speaker more convenient.

[0032] like Figure 4 and Figure 6 As shown, the fixed pad 2 is internally slidably connected with a push block 12; a spring is fixedly connected between the side wall of the push block 12 and the inner side wall of the fixed pad 2; the push block 12 is arranged at a position of the fixed frame body 1 close to the fixed back plate 9; during operation, when the fixed pad 2 is fixed by the expansion bolt, the push block 12 is pushed by the spring, so that the push block 12 can push the fixed position, so that the pressure between the expansion bolt and the bolt hole is greater, thereby making the friction between the expansion bolt and the bolt hole greater, so that the fixing effect of the fixed frame body 1 is better.

[0033] like Figure 1 to Figure 2 As shown, a protective cover 13 is fixedly connected to the side wall of the fixed frame 1; the protective cover 13 is arranged at a position corresponding to the top of the fixed frame 1; during operation, when the speaker is installed, the protective cover 13 can be installed toward the top of the fixed frame 1, and when the speaker is used, when water drips from the top of the speaker, the water is deflected by the protective cover 13, which can effectively prevent water from entering the rotating seat 3 and the interior of the sound module 4, which can easily cause a short circuit in the circuit of the sound module 4, resulting in damage to the sound module 4.

[0034] like Figures 1 to 3As shown, a plurality of guide slots 14 are provided on the side wall of the rotating seat 3; a limiting block 15 is fixedly connected inside the fixed frame body 1; the guide slot 14 is slidably connected to the limiting block 15; a plurality of guide blocks 16 are fixedly connected to the rotating shaft 6; the guide block 16 is rotatably connected at the internal position of the guide slot 14; during operation, when the sound module 4 is flipped into the fixed frame body 1, when water drops on the side wall of the fixed frame body 1, the water can be diverted by providing the guide slot 14 on the side wall of the rotating seat 3, thereby effectively avoiding water sticking to the surface of the rotating seat 3. At the same time, the guide slot 14 is restricted by the limiting block 15 and the guide block 16, so that the rotating seat 3 is less likely to tilt during rotation, and the rotation of the rotating seat 3 is more stable.

[0035] like Figure 2 , Figure 4 and Figure 6 As shown, a first support block 17 is fixedly connected to the outer wall of the fixed frame body 1; a pair of parallel and symmetrical first support blocks 17 are provided at the top and bottom of the fixed frame body 1; a pair of second support blocks 18 are fixedly connected to the side wall of the fixed back plate 9; the first support block 17 and the second support block 18 are arranged correspondingly; a plurality of protection blocks 19 are fixedly connected between a pair of the second support blocks 18; during operation, when the connecting wire 8 is led out through the top or bottom of the fixed frame body 1, the connecting wire 8 can be protected by the support of the first support block 17, and at the same time, a corresponding placement groove can be opened at the position where the connecting wire 8 does not pass through, so that the fixed frame body 1 can be placed inside the installation groove More stable, at the same time, the connecting wire 8 can be further protected by the support of the protection block 19, and the situation that the connecting wire 8 is squeezed and may be broken is effectively avoided.

[0036] like Figure 5 As shown, a guide rod 20 is fixedly connected to the interior of the fixed back plate 9; the guide rod 20 is arranged corresponding to the sliding direction of the sliding plate 10; the sliding plate 10 is slidably connected to the guide rod 20; when working, during the sliding process of the sliding plate 10, the sliding plate 10 is limited by the guide rod 20, which can make the sliding plate 10 more stable during the sliding process, and effectively avoid the sliding plate 10 from deflecting, which may cause the sliding of the sliding plate 10 to be stuck.

[0037] like Figures 5 and 6As shown, a sealing groove 22 is opened on the side wall of the fixed frame body 1; the sealing groove 22 is arranged at a position corresponding to one side of the fixed back plate 9; a sealing strip 21 is fixedly connected to the side wall of the fixed back plate 9; the sealing strip 21 and the sealing groove 22 are arranged correspondingly; during operation, when the fixed back plate 9 is fixed to the side of the fixed frame body 1, the sealing strip 21 is engaged with the sealing groove 22, so that the sealing between the fixed back plate 9 and the fixed frame body 1 can be made stronger, thereby protecting the rotating seat 3 and the sound module 4 inside the fixed frame body 1.

[0038] like Figure 2 and Figure 7 As shown, a positioning block 23 is fixedly connected to the end of the rotating shaft 6; the positioning block 23 is rotatably connected to the internal position of the fixed frame body 1; during operation, when the rotating shaft 6 rotates inside the fixed frame body 1, the rotation of the positioning block 23 is restricted by the fixed frame body 1, so that the rotating shaft 6 is less likely to tilt during the rotation process, and the rotation of the rotating shaft 6 is more stable.

[0039] like Figure 7 As shown, a plurality of anti-wear balls 24 are provided between the fixed frame body 1 and the positioning block 23; the side walls of the anti-wear balls 24 are in contact with the side walls of the fixed frame body 1 and the positioning block 23; during operation, when the positioning block 23 rotates inside the fixed frame body 1, by providing the anti-wear balls 24 between the fixed frame body 1 and the positioning block 23, the sliding friction between the fixed frame body 1 and the positioning block 23 can be converted into rolling friction, so that the friction force between the fixed frame body 1 and the positioning block 23 is smaller, thereby reducing the wear between the fixed frame body 1 and the positioning block 23.

[0040] During operation, when the speaker needs to be installed, an installation groove can be opened at the installation location, and a bolt hole can be opened at the position corresponding to the fixed pad 2. Then, the fixed frame 1 is inserted into the internal position of the installation groove, and the fixed frame 1 is fixed by cooperating with the bolt hole through the expansion bolt, and the installation of the speaker is completed. Later, during the use of the speaker, the rotating shaft 6 can be controlled to drive the meshing gear 7 to rotate, so that the meshing gear 7 is engaged with the meshing groove 5, and the rotating seat 3 is driven to rotate, so that the sound module 4 can be directed to the end of the fixed frame 1, so that a sound can be emitted. When the speaker is not in use, the rotating seat 3 can be controlled to rotate, so that the sound module 4 rotates to the position corresponding to the inside of the fixed frame 1, so that the sound module 4 can be protected, and the sound module 4 is effectively prevented from being affected by the outside world and possibly damaged.

[0041] During the installation of the speaker, the connecting wire 8 of the rotating seat 3 can be passed through the wire outlet hole and led out from the top or bottom of the fixed frame 1. During the rotation of the rotating seat 3, the connecting wire 8 will pull the sliding plate 10, so that the wire outlet hole will move with the connecting wire 8, effectively avoiding the connecting wire 8 from accumulating too much inside the fixed frame 1 after being pulled, which may easily cause the connecting wire 8 to become entangled, knotted or broken, making the use of the speaker more convenient.

[0042] When the fixed pad 2 is fixed by the expansion bolt, the pushing block 12 is pushed by the spring, so that the pushing block 12 pushes the fixing position, so that the pressure between the expansion bolt and the bolt hole is greater, thereby making the friction between the expansion bolt and the bolt hole greater, so that the fixing effect of the fixed frame 1 is better.

[0043] During the installation of the speaker, the protective cover 13 can be installed toward the top of the fixed frame 1. During the use of the speaker, when water drips from the top of the speaker, the water can be deflected by the protective cover 13, which can effectively prevent water from entering the rotating seat 3 and the interior of the sound module 4, which can easily cause a short circuit in the circuit of the sound module 4 and cause damage to the sound module 4.

[0044] When the sound module 4 is flipped into the fixed frame 1 and water drops on the side wall of the fixed frame 1, the water can be diverted by opening a guide groove 14 on the side wall of the rotating seat 3, thereby effectively preventing water from sticking to the surface of the rotating seat 3. At the same time, the guide groove 14 is restricted by the limit block 15 and the guide block 16, so that the rotating seat 3 is less likely to tilt during rotation, making the rotation of the rotating seat 3 more stable.

[0045] When the connecting wire 8 is led out through the top or bottom of the fixed frame 1, the connecting wire 8 can be protected by the support of the first support block 17. At the same time, a corresponding placement groove can be opened at the position where the connecting wire 8 does not pass, so that the fixed frame 1 can be placed inside the installation groove More stable, at the same time, with the support of the protection block 19, the connecting wire 8 can be further protected, effectively avoiding the situation where the connecting wire 8 is squeezed and may be broken.

[0046] During the sliding of the sliding plate 10, the sliding plate 10 is limited by the guide rod 20, which can make the sliding plate 10 more stable during the sliding process, and effectively avoid the sliding plate 10 from tilting, which may cause the sliding of the sliding plate 10 to get stuck.

[0047] When the fixed back plate 9 is fixed to the side of the fixed frame 1 , the sealing strip 21 is engaged with the sealing groove 22 , so that the sealing between the fixed back plate 9 and the fixed frame 1 can be made stronger, thereby protecting the rotating seat 3 and the sound module 4 inside the fixed frame 1 .

[0048] When the rotating shaft 6 rotates inside the fixed frame 1 , the fixed frame 1 limits the rotation of the positioning block 23 , so that the rotating shaft 6 is less likely to tilt during the rotation process, and the rotation of the rotating shaft 6 is more stable.

[0049] When the positioning block 23 rotates inside the fixed frame 1, by arranging the anti-wear balls 24 between the fixed frame 1 and the positioning block 23, the sliding friction between the fixed frame 1 and the positioning block 23 can be changed into rolling friction, so that the friction force between the fixed frame 1 and the positioning block 23 is smaller, thereby reducing the wear between the fixed frame 1 and the positioning block 23.
