DETAILED DESCRIPTION

[0032] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments: Example 1: A multifunctional speaker for outdoor use, see Figure 1-Figure 8, including a protection frame 11, a roller 12, a fixing frame 13, a clamping mechanism 2 and a closing mechanism 3. A sound 1 is placed inside the protection frame 11. Four fixing frames 13 are fixedly connected to the bottom of the protection frame 11, and each fixing frame 13 is rotatably connected to a roller 12. A clamping mechanism 2 is provided on the protection frame 11, and a closing mechanism 3 is provided on the upper part of the protection frame 11. The clamping mechanism 2 includes a first guide rod 21, a clamping frame 22, a first spring 23, a lower pressure plate 24 and a second spring 25. Four first guide rods 21 are fixedly connected to the left and right sides of the inner wall of the protection frame 11. The clamping frame 22 is slidably connected between the four first guide rods 21 on the left, and the clamping frame 22 is slidably connected between the four first guide rods 21 on the right. Each first guide rod 21 is sleeved with a first spring 23, and the two ends of the first spring 23 are respectively connected to The clamping frame 22 is connected to the protective frame 11, and the bottom of the protective frame 11 is connected to the lower pressure plate 24 through the second spring 25. The closing mechanism 3 includes a first closing plate 31, a second closing plate 32, a torsion spring 33, a blocking block 34 and a fourth spring 35. The first closing plate 31 is rotatably connected to the left side of the upper part of the protective frame 11, and the second closing plate 32 is rotatably connected to the right side of the upper part of the protective frame 11. The first closing plate 31 is sleeved with torsion springs 33 on both the front and rear sides, and the second closing plate 32 is sleeved with torsion springs 33 on both the front and rear sides. The two ends of the torsion spring 33 are respectively connected to the first closing plate 31, the second closing plate 32 and the protective frame 11. The left part of the second closing plate 32 is slidably connected to two blocking blocks 34 through two fourth springs 35. A through hole is opened on the right side of the first closing plate 31, and the top of the blocking block 34 is an inclined surface.

[0033] When in use, the speaker 1 is placed in the protective frame 11, and the clamping frame 22 clamps and limits the speaker 1. Under the action of the first spring 23 and the second spring 25, the speaker 1 can be cushioned to prevent the speaker 1 from vibrating violently during movement, thereby causing damage to the speaker 1 and affecting the sound quality. Then, the first closing plate 31 and the second closing plate 32 are closed, and the torsion spring 33 is deformed. The second closing plate 32 is closed first, and then the first closing plate 31 is closed. The first closing plate 31 contacts the positioning block 34, thereby squeezing the positioning block 34 to move inward. The fourth spring 35 is compressed, and when the first closing plate 31 passes over the blocking block 34, the fourth spring 35 is reset, driving the blocking block 34 to move outward and reset. In this way, the first closing plate 31 and the second closing plate 32 can be locked, and then the top of the speaker 1 can be protected to prevent the speaker 1 from shaking up and down. When the speaker 1 needs to be taken out, the blocking block 34 is manually pressed inward to no longer block the first closing plate 31, and the torsion spring 33 is reset, driving the first closing plate 31 and the second closing plate 32 to rotate and open, and then the speaker 1 can be taken out.

[0034] Example 2: Based on Example 1, please refer to Figure 1 , Figure 2 and Fig. 9, and also includes a buffer mechanism 4, which includes a buffer plate 41, a fifth spring 42 and a second guide rod 43. Two second guide rods 43 are slidably connected to the upper and lower sides of the front of the protection frame 11. A buffer plate 41 is fixed between the front sides of the two second guide rods 43 on the upper side, and a buffer plate 41 is fixed between the front sides of the two second guide rods 43 on the lower side. Each second guide rod 43 is sleeved with a fifth spring 42, and the two ends of the fifth spring 42 are respectively connected to the second guide rod 43 and the protection frame 11. When the protection frame 11 tilts forward, since the paper plate on the speaker 1 is relatively fragile, the impact force can be buffered under the buffering action of the buffer plate 41 and the fifth spring 42, and the speaker 1 and the protection frame 11 can be supported. In this way, the speaker 1 can be protected to prevent the paper plate at the speaker position of the speaker 1 from being damaged.

[0035] See also Figure 2 , Fig.10 and Fig.11 , and also includes a protection mechanism 5, which includes a push plate 51, a guide frame 52 and an air cushion 53. The guide frames 52 are fixedly connected to the upper and lower sides of the front of the protection frame 11. The push plates 51 are connected to the two buffer plates 41. The two push plates 51 are slidably connected to the adjacent guide frames 52. The front wall of the protection frame 11 is connected to two air cushions 53. The front of the protection frame 11 has two strip holes, and the two air cushions 53 are connected to the adjacent protection frame 11. When the protection frame 11 tilts forward, the buffer plate 41 moves backward to drive the push plate 51 to move backward, and then pushes the air in the guide frame 52 into the air cushion 53, so that the air cushion 53 supports the sound box 1, cushions the sound box 1 when it tilts, and cushions the impact force when it tilts, so that the sound box 1 can be protected and prevented from being damaged. When the buffer plate 41 is reset, it drives the push plate 51 to move forward and reset, so that the air in the air cushion 53 is drawn back for the next use.

[0036] See also Figure 1 , Figure 2 , Fig.12 , Fig.13 and Fig.14, and also includes an extension mechanism 6, which includes a pull rod 61, a fixed frame 62, a clamping frame 63 and a sixth spring 64. Two fixed frames 62 are fixedly connected to the rear side of the protection frame 11, and a pull rod 61 is slidably connected between the two fixed frames 62. A clamping hole is opened on the pull rod 61, and a clamping frame 63 is clamped between the rear sides of the two fixed frames 62. The left and right sides of the clamping frame 63 are sleeved with a sixth spring 64, and the two ends of the sixth spring 64 are respectively connected to the clamping frame 63 and the fixed frame 62. When the speaker 1 and the protection frame 11 need to be moved, the clamping frame 63 is pulled backward, the sixth spring 64 is stretched, and then the pull rod 61 is pulled out, and then the clamping frame 63 is released, and the sixth spring 64 is reset, driving the clamping frame 63 to move forward and reset into the clamping hole on the pull rod 61. In this way, the pull rod 61 can be locked, and then the movement of the protection frame 11 and the speaker 1 can be controlled. When reset is required, the above operation can be repeated.

[0037] See also Figure 2 , Fig.15 and Fig.16 , also includes a stabilizing mechanism 7, the stabilizing mechanism 7 includes a seventh spring 71, a clamping plate 72, a lower pressure frame 73 and an eighth spring 74, the two rear fixing frames 13 are slidably connected to two clamping plates 72, each clamping plate 72 is sleeved with a seventh spring 71, the two ends of the seventh spring 71 are respectively connected to the rear fixing frame 13 and the clamping plate 72, the left and right sides of the rear lower part of the protective frame 11 are slidably connected to the lower pressure frames 73, the lower part of the lower pressure frame 73 is an inclined surface in contact with the clamping plate 72, the bottom of the pull rod 61 is in contact with the tops of the two lower pressure frames 73, each lower pressure frame 73 is sleeved with two eighth springs 74 on the upper part, and the two ends of the eighth spring 74 are respectively connected to the lower pressure frame 73 and the protective frame 11. When the pull rod 61 moves downward, the lower pressure frame 73 is squeezed to move downward, the eighth spring 74 is compressed, the lower pressure frame 73 squeezes the clamping plate 72 to move inward and contact the roller 12 on the rear side, and the seventh spring 71 is stretched. In this way, the roller 12 can be prevented from rolling and affecting the stability of the speaker 1. When it is necessary to move, the pull rod 61 moves upward, the eighth spring 74 is reset, and the lower pressure frame 73 is moved upward and separated from the clamping plate 72. The seventh spring 71 is reset, and the clamping plate 72 is moved outward and separated from the roller 12. In this way, automatic braking can be achieved, and the operation is convenient.
