[0028] As Figures 1 to 7 shown, a teaching sound amplification device for teaching and training provided by a specific embodiment of the present utility model includes a loudspeaker body 1 and a belt 2 provided on the loudspeaker body 1. A receiving groove 3 is opened in the loudspeaker body 1, a bracket 4 is provided in the receiving groove 3, and a storage assembly for rolling up the belt 2 is provided on the bracket 4. By providing the storage assembly, it is convenient to store the longer belt 2 after the loudspeaker body 1 is used, preventing the belt 2 from being easily forgotten to be carried when the loudspeaker body 1 is used again next time. The storage assembly includes a storage cylinder 5 fixedly connected to the bracket 4. A cylinder 6 is rotatably connected in the storage cylinder 5. A connecting rod 7 is provided in the cylinder 6, and the belt 2 is fixedly connected to the connecting rod 7; further includes a support assembly provided on the bracket 4 for enhancing the stability of the loudspeaker body 1. By providing the support assembly, when the loudspeaker body 1 is placed on a table during teaching use and makes a relatively large sound to generate vibration, it will not tip over and affect the use. The support assembly includes a support plate 8 provided in the bracket 4. A limiting rod 9 is fixedly connected to the support plate 8. A limiting groove 10 is opened in the receiving groove 3, and the limiting rod 9 is slidably connected in the limiting groove 10.

[0029] As Figures 1 to 7As shown, specifically, a rotating plate 12 is fixedly installed on the upper part of the cylinder 6. A notch 13 is provided on the cylinder 6, and a slot 14 is provided on the storage cylinder 5. The belt 2 passes through the notch 13 and the slot 14. A push plate 15 is slidably connected to the storage cylinder 5. A connecting plate 16 is fixedly connected to the push plate 15, and a spring 17 is fixedly connected between the connecting plate 16 and the storage cylinder 5. A pressing rod 18 is rotatably connected to the push plate 15, and the pressing rod 18 is in close contact with the belt 2. Specifically, when it is necessary to store the belt 2 on the loudspeaker body 1 after the teaching and training, rotate the rotating plate 12 to drive the cylinder 6 to rotate. The rotation of the cylinder 6 drives the connecting rod 7 to rotate. Thus, under the rotation of the connecting rod 7, the belt 2 connected to the connecting rod 7 gradually winds around the cylinder 6. Since the belt 2 passes through the notch 13 and the slot 14, under the action of the spring 17, the pressing rod 18 is in close contact with the belt 2 and applies pressure to the belt 2. Therefore, during the process of the cylinder 6 rotating to pull the belt 2 to wind around the cylinder 6, under the action of the pressure, the belt 2 is always in a straight and tight state, so that the belt 2 can better wind around the cylinder 6 tightly in circles. A rubber cushion block 24 is provided on the belt 2. Stop rotating the rotating plate 12 until the rubber cushion block 24 moves to the top of the slot 14 during the storage process. At this time, the storage of the belt 2 in the storage cylinder 5 is completed. The setting of the rubber cushion block 24 can prevent it from being stuck at the top of the slot 14 and prevent the belt 2 from completely entering the storage cylinder 5 during storage. When taking out the belt 2 and wearing the loudspeaker body 1 on the body, pull the push plate 15 to drive the connecting plate 16 and the pressing rod 18 away from the belt 2 in the slot 14. At this time, the spring 17 is stressed and contracts to generate a reaction force. Then, pull the rubber cushion block 24 to drive the belt 2 to move upward. Thus, the belt 2 wound around the cylinder 6 gradually moves out of the storage cylinder 5. After the belt 2 completely moves out of the storage cylinder 5, the taking-out of the belt 2 is completed. Then, stop pulling the push plate 15. The push plate 15 moves back to its original position under the reaction force of the spring 17, so that the pressing rod 18 is reset to be in close contact with the belt 2 again.

[0030] As Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, specifically, a sliding groove 11 is provided in the cylinder 6, and the connecting rod 7 is slidably connected in the sliding groove 11. A short plate 19 is fixedly installed in the storage cylinder 5. A sealing plate 20 adapted to the storage cylinder 5 is provided in the storage cylinder 5, and the sealing plate 20 is bolted to the short plate 19. The sealing plate 20 can be removed by rotating the bolt. Then, pull the push plate 15 so that the pressing rod 18 no longer applies force to the belt 2 in a close contact manner. Thus, the connecting rod 7 in the sliding groove 11 can be pulled to take out the connecting rod 7 from the cylinder 6. During the process of the connecting rod 7 moving out of the cylinder 6, the belt 2 is driven to move out of the notch 13 and the slot 14. Therefore, the belt 2 can be replaced. After the replacement is completed, insert the connecting rod 7 into the cylinder 6 again, and the belt 2 passes through the notch 13 and the slot 14 again and returns to its original position.

[0031] AsFigure 2 , Figure 3 , Figure 5 and Figure 7 As shown, specifically, a semi-circular bump 21 is fixedly connected to the bracket 4, a clamping groove 22 adapted to the bump 21 is provided in the receiving groove 3, and the bump 21 is embedded in the clamping groove 22. A placement groove 23 adapted to the support plate 8 is provided in the bracket 4. A first rotating shaft is rotatably connected between the support plate 8 and the placement groove 23, and a second rotating shaft is rotatably connected between the bracket 4 and the receiving groove 3. When the loudspeaker body 1 is placed on the table, the bracket 4 is pulled so that the bump 21 is disengaged from the clamping groove 22 under the action of the pulling force, so that the bracket 4 rotates away from the receiving groove 3 with the second rotating shaft. During the process of the bracket 4 disengaging from the receiving groove 3, the support plate 8 rotates away from the placement groove 23 with the first rotating shaft of the bracket 4 and makes the limiting rod 9 slide in the limiting groove 10 until the bracket 4 is fully unfolded. At this time, the storage cylinder 5 on the unfolded bracket 4 contacts the table and supports the loudspeaker body 1 under the cooperation of the bracket 4 and the support plate 8, preventing the loudspeaker body 1 from tipping over due to the vibration generated by the sound. When the bracket 4 is rotated in the reverse direction with the second rotating shaft, the bracket 4 gradually moves into the receiving groove 3. At this time, the bracket 4 drives the support plate 8 to gradually enter the placement groove 23 with the first rotating shaft, and the limiting rod 9 on the support plate 8 gradually moves back in the limiting groove 10. Until the bracket 4 is completely reset and enters the receiving groove 3, the support plate 8 is completed to be reset. During the process of the bracket 4 entering the receiving groove 3, the bump 21 is re-engaged into the clamping groove 22, thereby completing the fixation of the bracket 4 in the receiving groove 3.
