DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: it includes a base 1 and a speaker body 2, the speaker body 2 is rotatably connected to the upper end of the base 1, a positioning component is arranged at the connection between the upper end of the base 1 and the bottom of the speaker body 2, a fixing groove 3 is opened in the middle position of the lower end of the base 1, a pair of clamping plates 31 are slidably connected in the fixing groove 3, a driving component for synchronously driving the clamping plate 31 is arranged in the upper side wall of the fixing groove 3, a central rotating shaft 11 is rotatably connected to the center position of the upper end of the base 1, the upper end of the central rotating shaft 11 is fixed to the bottom of the speaker body 2, an arc structure is arranged on one side close to the clamping plate 31, and an anti-slip pad 32 is fixed, a pair of limiting grooves 6 are opened in the upper side wall of the fixing groove 3, and a limiting block is fixed at the upper end of the clamping plate 31 and at a position corresponding to the limiting groove 6.

[0019] The driving assembly includes a driving groove 4 and a bidirectional screw 41. The driving groove 4 is opened in the upper side wall of the fixing groove 3. A pair of threaded sleeves 42 are slidably connected in the driving groove 4. The bottom of the threaded sleeve 42 is fixed to the clamping plate 31 by a connecting block. The driving groove 4 is rotatably connected with the bidirectional screw 41. The bidirectional screw 41 passes through the threaded sleeve 42 and is threadedly connected with the threaded sleeve 42. A rotating plate 43 is rotatably connected to the outside of the base 1 and at a position corresponding to the bidirectional screw 41. The rotating plate 43 is fixed to the end of the bidirectional screw 41.

[0020] The positioning assembly includes a positioning hole 21 and a positioning column 5. The positioning hole 21 is opened on the outer periphery of the bottom of the speaker body 2. The positioning column 5 is installed on the upper end of the base 1 and its position is aligned with the positioning hole 21. The upper end of the positioning column 5 is inserted into one of the positioning holes 21. A telescopic groove 51 is opened at the upper end of the base 1 and at a position corresponding to the positioning column 5. The bottom of the positioning column 5 is slidably connected in the telescopic groove 51, and a spring is fixed between the bottom of the telescopic groove 51.

[0021] Working principle: By rotating the counter-rotating plate 43, the bidirectional screw 41 can be rotated, thereby driving the threaded sleeve 42 to move in the opposite direction in synchronization in the driving groove 4, and finally the clamping plate 31 can move in the opposite direction in synchronization in the fixing groove 3. Therefore, the fixing part is placed between the clamping plates 31, so that the base 1 can be fixed on the fixing part, such as a tree branch or a bicycle handlebar. In this process, the arc structure on the side close to the clamping plate 31 and the anti-slip pad 32 can increase the stability of the clamping fixation, and can be fixed on more non-planar objects, increasing the scope of application. After fixation, the rotation of the speaker body 2 can be used to change the opening direction of the sound expansion port, so that the sound propagated in the speaker body 2 can be better heard. In this process, the positioning column 5 needs to be pressed down, and when the spring is compressed, it is pulled out of the positioning hole 21 so that the speaker body 2 can rotate freely. After rotating to the specified position, the positioning column 5 is released, reset, and reinserted into the positioning hole 21. The operation is simple and convenient.
