[0024] See also Figure 1-3 , This embodiment provides a technical solution: a ceiling speaker that is easy to install, including a mounting base 1 and a fixing mechanism 8;

[0025] Mounting base 1: The middle part of the mounting base 1 is rotatably connected with a rotating shaft 3, the middle part of the rotating shaft 3 is fixedly connected with a rotating rod 4, the rear end of the mounting base 1 is provided with evenly distributed fixed feet 2, and also includes a control switch group 9, the control switch group 9 is arranged outside the mounting base 1, the input end of the control switch group 9 is electrically connected to an external power supply, a motor 6 is arranged at the lower end of the front side of the mounting base 1, a worm 7 is arranged at the front end of the output shaft of the motor 6, a worm wheel 5 is arranged at the lower end of the rotating shaft 3, the worm wheel 5 is meshed and connected with the worm 7, the input end of the motor 6 is electrically connected to the output end of the control switch group 9, if the angle of the speaker 10 needs to be adjusted, the motor 6 can be turned on by the control switch group 9, the output shaft of the motor 6 rotates to drive the worm 7 to rotate, the worm 7 drives the worm wheel 5 to drive the rotating shaft 3 to rotate in the mounting base 1, so as to realize the angle adjustment of the speaker 10, and the angle of the fixing device is adjustable, and the sound effect can be adjusted by changing the angle of the speaker playback, which has strong flexibility;

[0026] The fixing mechanism 8 includes a rotating seat 82, a rotating disk 83, a fixed platform 84, a fixed seat 85, a guide column 86 and a guide groove 89. The fixed platform 84 is rotatably connected to the rotating disk 83. The rear end of the rotating disk 83 is fixedly connected to the rotating seat 82. The rear end of the rotating seat 82 is rotatably connected to the front end of the rotating rod 4. The sliding openings on the front side of the fixed platform 84 are slidably connected to the fixed seats 85 corresponding to the left and right positions. The rear ends of the two fixed seats 85 are fixedly connected to the guide column 86 on the sides close to the center of the fixed platform 84. The middle part of the rotating disk 83 is provided with evenly distributed guide grooves 89. The guide grooves 89 are slidably connected to the guide columns 86 adjacent to the front side. The fixing mechanism 8 also includes a locking assembly 87. The assembly 87 includes a shifting block 871, a connecting column 872, a locking block 873 and a locking groove 874. The upper ends of the rear sides of the rotating disk 83 and the fixed platform 84 are both provided with locking grooves 874. The two locking grooves 874 are symmetrically distributed up and down. The lower end of the locking groove 874 located on the rear side of the fixed platform 84 is rotatably connected with the locking block 873. The middle part of the rear end of the locking block 873 is fixedly connected with the connecting column 872. The rear end of the connecting column 872 is fixedly connected with the shifting block 871. The fixing mechanism 8 also includes a shifting rod 81, which is fixedly connected to the lower end of the rear side of the rotating seat 82. The fixing mechanism 8 also includes a fixing frame 88. The front ends of the two fixed seats 85 are both provided with fixing frames 88. The two fixing frames 88 are located at the left and right positions. Correspondingly, an audio device 10 is arranged between the two fixing frames 88, and the input end of the audio device 10 is electrically connected to the output end of the control switch group 9. First, the mounting seat 1 is installed in the preset area, and then the lever 81 is toggled counterclockwise. Since the central axes of the rotating seat 82, the rotating disk 83 and the fixed platform 84 coincide, the lever 81 drives the rotating seat 82 so that the rotating seat 82 drives the rotating disk 83 to rotate in the fixed platform 84, so that the guide groove 89 follows the rotation and changes the angle, forcing the guide groove 89 to slide and guide the guide column 86. Since the positions of the two guide grooves 89 correspond, the guide column 86 drives the adjacent fixing seat 85 on the front side to move away from the fixing platform in the slide groove at the front end of the fixing platform 84. 84 slides at the center, and drives the fixing frame 88 to slide, so that the two fixing frames 88 move away from each other. At this time, put the speaker 10 into one of the fixing frames 88, and push the lever 81 in the opposite direction to make the two fixing frames 88 close to each other so as to fix the speaker 10. After the fixation is completed, push the push block 871 in the clockwise direction. Since the central axis of the connecting column 872 and the locking block 873 coincide with each other, the pushing block 871 drives the connecting column 872 to rotate, and finally the transmission locking block 873 rotates to the locking groove 874 located at the upper end of the fixing platform 84, so that the fixing platform 84 and the rotating disk 83 are temporarily fixed, thereby realizing the locking of the two fixing frames 88. The fixing device is separately arranged from the speaker, which is convenient for quick disassembly and assembly of the speaker.

[0027] The working principle of a ceiling speaker that is easy to install provided by the utility model is as follows: when it is necessary to lay out a ceiling speaker that is easy to install, the audio layout staff needs to first install the mounting seat 1 in a preset area, and then toggle the lever 81 in a counterclockwise direction. Since the central axes of the rotating seat 82, the rotating disk 83 and the fixed platform 84 coincide, the lever 81 drives the rotating seat 82 so that the rotating seat 82 drives the rotating disk 83 to rotate in the fixed platform 84, so that the guide groove 89 follows the rotation and changes the angle, forcing the guide groove 89 to slide and guide the guide column 86. Since the positions of the two guide grooves 89 correspond, the guide column 86 drives the adjacent fixed seat 85 on the front side to slide in the slide groove at the front end of the fixed platform 84 away from the center of the fixed platform 84, and drives the fixed frame 88 to slide, so that the two fixed The rack 88 is away, at this time, the speaker 10 is placed in one of the fixing racks 88, and the lever 81 is toggled in the opposite direction to make the two fixing racks 88 close to each other so as to fix the speaker 10. After the fixation is completed, the block 871 is toggled in the clockwise direction. Since the central axis of the connecting column 872 and the locking block 873 coincide, the toggling block 871 drives the connecting column 872 to rotate, and finally the transmission locking block 873 rotates to the locking groove 874 located at the upper end of the fixing platform 84, so that the fixing platform 84 and the rotating disk 83 are temporarily fixed, so as to realize the locking of the two fixing racks 88. If the angle of the speaker 10 needs to be adjusted, the motor 6 can be turned on by controlling the switch group 9, and the output shaft of the motor 6 rotates to drive the worm 7 to rotate, and the worm 7 drives the worm wheel 5 to drive the rotating shaft 3 to rotate in the mounting seat 1, so as to realize the angle adjustment of the speaker 10.

[0028] It is worth noting that the motor 6 disclosed in the above embodiment can be selected as CM21-ER16.ER20, and the speaker 10 can be selected as IP-20WX. The control switch group 9 is provided with buttons corresponding to the motor 6 and the speaker 10 one by one and controlling the switching thereof.

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
