[0027] The following is combined with Figure 1-7 To further explain this application in detail,

[0028] The present application embodiment discloses a speaker. Figure 1 and Figure 2 A sound system, comprising a sound system body 1; a protection component 2 is disposed at the rear end of the sound system body 1, a limiting component 3 is disposed on the surface of the protection component 2, and a shielding component 4 is disposed on the surface of the protection component 2;

[0029] Reference Figure 2-Figure 5 The protection component 2 includes two fixing plates 21 fixedly installed on the left and right sides of the rear end of the sound body 1. A slide groove 22 is opened inside the fixing plate 21. A fixing rod 23 is fixedly installed inside the slide groove 22. A slider 24 is slidably connected to the surface of the fixing rod 23. A pull rod 25 is fixedly installed on the top of the slider 24. A gripping rod 26 is fixedly installed on the top of the pull rod 25. The upper and lower ends of the fixing rod 23 are respectively fixedly installed on the upper and lower inner walls of the slide groove 22. The top of the pull rod 25 extends to the outside of the fixing plate 21. The gripping rod 26 is fixedly connected to the top of the two pull rods 25. The operator pulls the gripping rod 23 upwards. 6, the pulling rod 25 will be driven to extend to the outside of the fixed plate 21, so that the operator can lift the audio body 1. The top wall of the slide groove 22 is fixedly installed with a buffer spring 27, and the bottom end of the buffer spring 27 is fixedly installed with a buffer block 28. The inside of the fixed plate 21 is rotatably connected with a roller 29. The bottom end of the buffer block 28 and the top end of the slider 24 are in adaptive contact. When the pulling rod 25 is pulled to slide upward, it will press on the bottom end of the buffer block 28. At this time, the buffer spring 27 is compressed to prevent the pulling rod 25 from directly colliding with the top wall of the slide groove 22, thereby preventing the pulling rod 25 from being damaged. The roller 29 is rollingly connected to the surface of the pulling rod 25.

[0030] Reference Figure 6-Figure 7The limiting component 3 includes a support rod 301 fixedly installed at the bottom of the proximal end of the two fixed plates 21, the surface of the support rod 301 is rotatably connected to a rotating plate 302, a groove 303 is provided on the front end surface of the rotating plate 302, vertical grooves 304 are provided on the left and right sides of the groove 303, rolling rods 305 are rollingly connected inside the two vertical grooves 304, a rotating plate 306 is fixedly connected on the surface of the rolling rod 305, a card slot 307 is provided at one end of the rotating plate 306 close to the rotating plate 302, a threaded plug rod 308 is threadedly connected to the internal thread of the rotating plate 306, a card block 309 is fixedly installed inside the groove 303, and the proximal ends of the two fixed plates 21 are fixedly installed The reset spring 310, the rotating plate 306 and the groove 303 are adapted and snap-fitted, the block 309 and the slot 307 are adapted and snap-fitted, the end of the threaded rod 308 away from the rotating plate 306 extends to the outside of the rotating plate 306, and the end of the threaded rod 308 away from the rotating plate 306 is in a conical shape. The operator can rotate the threaded rod 308 so that its top abuts against the ground, so that the threaded rod 308 supports and limits the rotating plate 306. At this time, the rotating plate 302 supports and limits the audio body 1. The two reset springs 310 are adapted and contacted with the left and right ends of the rotating plate 302 respectively, and the other end of the reset spring 310 is fixedly installed with a pressing block 311.

[0031] Reference Figure 2 The shielding component 4 includes side grooves 41 opened at the opposite ends of the two fixed plates 21, and the surfaces of the two fixed plates 21 are slidably connected with shielding plates 42. The top-view cross-sectional shape of the shielding plate 42 is a "concave" shape. The inner walls on the left and right sides of the shielding plate 42 are fixedly connected with protrusions slidably connected to the inside of the side grooves 41. The height of the shielding plate 42 is greater than the height of the rotating plate 302. The shielding plate 42 blocks the groove 303 to prevent the rotating plate 302 from being exposed to the outside, thereby preventing the edges of the surface components of the rotating plate 302 from scratching people using the audio body 1.

[0032] Working principle: When the operator needs to carry the audio body 1, he first holds the grip 26 and pulls the pull rod 25 fixed at the bottom to move upward. At this time, the pull rod 25 drives the fixed slider 24 to move upward inside the slide groove 22, and the slider 24 moves upward on the surface of the fixed rod 23 until the top of the slider 24 abuts against the bottom end of the buffer block 28. At this time, the slider 24 will push the buffer block 28 to compress the buffer spring 27. The elastic force of the buffer spring 27 prevents the slider 24 from directly colliding with the top wall of the slide groove 22, and in the process of the pull rod 25 sliding upward, it will slide on the surface of the roller 29. When the buffer spring 27 is compressed to the limit state, the operator can directly lift the grip 26 and then lift the audio body 1 and carry it.

[0033] After the audio body 1 is brought to the expected position, the operator pushes the shielding plate 42 upwards. At this time, the shielding plate 42 slides upward inside the side groove 41 and no longer blocks the rotating plate 302. Since the pressing block 311 is in contact with the side wall of the rotating plate 302 under the action of the elastic force of the return spring 310 in the initial state, and at this time the rotating plate 302 is away from the side of the support rod 301 and faces upward, the operator can then compress the two return springs 310 to make the pressing block 311 disengage from the side wall of the rotating plate 302. At this time, the operator rotates the rotating plate 302 so that the end away from the support rod 301 faces downward, and then the operator pulls the top of the rotating plate 306 so that the rotating plate 306 opens The slot 307 is disengaged from the block 309, and then the rotating plate 306 is continued to be pushed to rotate so that the top of the rotating plate 306 faces the ground, and at this time, the rolling rod 305 moves upward inside the vertical slot 304 until the rolling rod 305 moves to the top of the vertical slot 304. Then the operator rotates the threaded rod 308 again to move the threaded rod 308 away from the rotating plate 306 until the cone of the threaded rod 308 abuts against the ground. At this time, the threaded rod 308 supports the rotating plate 306, and the rotating plate 306 supports the rotating plate 302, and the rotating plate 302 supports the audio body 1, so that the audio body 1 will not move at will during use.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
