[0022] 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.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a special audio device for a projector, including a body 1, a connecting member 2 is fixedly connected to the side wall of the body 1, a sliding column 3 is slidably connected inside the connecting member 2, a sliding table 4 is slidably connected to the outer wall of the sliding column 3, a sliding groove 5 is opened inside the sliding table 4, an annular groove 6 is opened inside the sliding table 4, a turntable 8 is fixedly connected inside the connecting member 2, a rotating rod 9 is rotatably connected inside the turntable 8, one end of the rotating rod 9 is slidably connected inside the sliding groove 5, a spring 7 is sleeved on one end of the outer wall of the sliding column 3, and a fixing component is arranged at the bottom of the body 1.

[0024] Specifically, pressing the joint triggers the sliding mechanism. This action causes the slide column 3 to slide in the connector 2, and at the same time drives the slide 4 on the outer wall to move synchronously. As the slide 4 moves downward, the rotating rod 9 starts to rotate inside the turntable 8 and changes its own inclination angle accordingly. The rotation of the rotating rod 9 causes the other end of the rotating rod 9 to slide in the slide groove 5. When the slide 4 slides to the bottom of the connector 2, one end of the rotating rod 9 enters the annular groove 6 to lock the slide 4 in place. Pressing the joint again causes one end of the rotating rod 9 to slide out of the annular groove 6 and enter the slide groove 5. The setting of the spring 7 ensures rapid reset. This design makes the joint retractable and very convenient to operate. The overall structural design provides the necessary protection for long-term safe use.

[0025] Reference Figure 3 The fixed component includes a support platform 11, which is fixedly connected to the lower surface of the body 1. A base plate 10 is arranged at the bottom of the support platform 11, and a motor 12 is arranged inside the base plate 10. A forward and reverse screw rod 14 is fixedly connected to the output end of the motor 12. A plurality of turntables 13 are fixedly connected inside the base plate 10. The forward and reverse screw rods 14 are rotatably connected inside the turntable 13. A plurality of sliders 15 are threadedly connected to the outer wall of the forward and reverse screw rods 14. A connecting column 16 is fixedly connected to the side wall of the slider 15. A rotating wheel 17 is rotatably connected to the bottom of the support platform 11. An annular groove 18 is opened inside the base plate 10, and the connecting column 16 is slidably connected inside the annular groove 18.

[0026] Specifically, the motor 12 outputs a rotational force through the forward and reverse screw rods 14, driving the forward and reverse screw rods 14 to rotate inside the turntable 13. The rotation of the forward and reverse screw rods 14 is connected to the plurality of sliders 15 in different directions through threads, so that the sliders 15 make relative displacements on the outer walls of the forward and reverse screw rods 14. The displacement of the sliders 15 simultaneously drives the connecting columns 16 on the side walls thereof to move synchronously. The movement of the connecting columns 16 causes the rotating wheel 17 to rotate at the bottom of the support 11, thereby changing the direction of the support 11. This design allows the sound direction of the audio equipment to be easily changed without moving the entire equipment, thereby reducing the difficulty of operation and increasing the versatility of the audio equipment.

[0027] Working principle: when it is necessary to use the connector of this audio equipment for connection, first press the connector to make the slide post 3 slide inside the connector 2. While the slide post 3 moves, it drives the slide table 4 on its outer wall to move synchronously. During the downward displacement of the slide table 4, it drives the rotating rod 9 to rotate inside the turntable 8 and change its own inclination angle. The rotation of the rotating rod 9 makes the other end slide inside the slide groove 5. When the slide table 4 slides to the bottom of the connector 2, one end of the rotating rod 9 enters the annular groove 6 to lock the slide table 4. Pressing the connector again can make one end of the rotating rod 9 slide out of the range of the annular groove 6 and enter the slide groove 5, and realize rapid reset through the setting of the spring 7. Therefore, the structure can achieve the effect of retractable connector and convenient operation, which is convenient for the length of the connector. The invention provides a guarantee for the safe use of the period. When the sound direction of the audio device needs to be changed, the motor 12 is started. The motor 12 outputs a rotating force to the forward and reverse screw rods 14, driving the forward and reverse screw rods 14 to rotate inside the turntable 13. While the forward and reverse screw rods 14 rotate, they are connected with multiple sliders 15 in different directions through threads, so that the sliders 15 make relative displacement on the outer walls of the forward and reverse screw rods 14. While the sliders 15 are displaced, the connecting columns 16 of the side walls are driven to move synchronously. The movement of the connecting columns 16 can make the rotating wheel 17 rotate at the bottom of the support 11, thereby changing the direction of the support 11, thereby changing the sound direction of the audio device. There is no need to carry the entire device, which reduces the difficulty of operation and increases the versatility of the audio device.
