[0033] Specific examples are given below.

[0034] See also Figures 1 to 10As shown, a portable sports speaker described in an embodiment of the present invention includes a speaker body 1; a plurality of first slide grooves 17 are opened on the top of the speaker body 1; a connecting plate 12 is provided on the top of the speaker body 1; a plurality of first sliders 16 are fixedly connected to the bottom of the connecting plate 12; the first sliders 16 and the first slide grooves 17 are correspondingly arranged and slidingly matched; an outer gear ring 13 is rotatably connected to the middle part of the connecting plate 12; a plurality of gears 14 are rotatably connected to the inner side wall of the connecting plate 12; the connecting plate 12 and the gear 14 are meshing transmission; a baffle 15 is fixedly connected to the top of the gear 14; the baffle 15 is an arc structure; the ends of the adjacent baffles 15 are correspondingly arranged; the speaker body 1 will work normally when in use, and when the speaker body 1 needs to be placed in a dustproof manner, the user can move the connecting plate 12 along the first slider 16 and the first slide groove 17 is aligned, and then the connecting plate 12 is inserted into the top of the speaker body 1. The connecting plate 12 makes the first slider 16 enter the inside of the first slide groove 17 and generate friction, so that the connecting plate 12 is fixed on the top of the speaker body 1. Then the user can rotate the outer gear ring 13 to make the outer gear ring 13 rotate. When the outer gear ring 13 rotates, it will mesh with the gear 14 and make the gear 14 rotate. When the gear 14 rotates, it will drive the baffle 15 to move together. When the adjacent baffles 15 move, they will approach each other. During the process of the baffles 15 approaching, the gap between them will gradually shrink until the adjacent baffles 15 contact and form a closed shape, thereby realizing dust-proof treatment of the speaker body 1; rotating the outer gear ring 13 can make the baffle 15 seal the speaker body 1, realize dust-proof treatment of the speaker body 1 when the device is placed, and reduce dust and other impurities attached to the surface of the speaker body 1 when it is placed for a long time.

[0035] See also Figure 3 and Figure 4As shown, a first fixed groove 2 is provided in the middle of the baffle 15; a plurality of first springs 22 are fixedly connected to the inner side wall of the first fixed groove 2; a slide plate 23 is fixedly connected to the end of the first spring 22; the slide plate 23 and the first fixed groove 2 are in sliding fit; a second fixed groove 24 is provided in the middle of the baffle 15; the slide plate 23 and the second fixed groove 24 are in sliding fit; the slide plate 23 and the second fixed groove 24 are both arc-shaped structures; a first magnet 25 is fixedly connected to the middle of the slide plate 23; a second magnet 26 is fixedly connected to the inner side wall of the second fixed groove 24; the first magnet 25 and the second magnet 26 are correspondingly arranged; the first magnet 25 and the second magnet 26 are both arc-shaped structures; when the baffle 15 approaches each other, the first fixed groove 2 and the second fixed groove 24 The distance will also be closer. During the movement of the baffle 15, the distance between the first magnet 25 and the second magnet 26 will gradually decrease. The first magnet 25 will be attracted by the second magnet 26, so that the slide plate 23 will slide along the first fixed groove 2 and enter the second fixed groove 24 under the magnetic force of the first magnet 25 and the second magnet 26. Because the depth of the second fixed groove 24 is less than the thickness of the slide plate 23, the slide plate 23 will fill the gap between the second fixed groove 24 and the first fixed groove 2 and the second fixed groove 24; the slide plate 23 will move under the magnetic force of the first magnet 25 and the second magnet 26 and close the gap between the baffles 15, thereby reducing the gap width at the connection between the baffles 15 and enhancing the dust-proof sealing of the baffle 15 on the speaker body 1.

[0036] See also Figure 4 As shown, the middle part of the skateboard 23 is rotatably connected with a plurality of balls 3; the balls 3 are arranged in an array; when the skateboard 23 moves, it moves with the balls 3, and when the balls 3 move, they come into contact with the first fixed groove 2 and rotate, and when the balls 3 rotate, the sliding friction between the skateboard 23 and the first fixed groove 2 is converted into rolling friction, thereby reducing the friction between the skateboard 23 and the first fixed groove 2, so that the skateboard 23 can more stably fill the gap between the second fixed groove 24 and the first fixed groove 2.

When the pressure rod 43 moves, the second spring 42 will be in a stretched state, and at the same time, the pressure rod 43 will push the top plate 44 to move along the cavity 4 and enter the first slide groove 1 7, when the top plate 44 moves, its bottom will contact the first slider 16 and make the first slider 16 move along the surface of the top plate 44. Because the top plate 44 is a trapezoidal structure, the first slider 16 will slowly rise along the first slide groove 17. At this time, the friction between the first slider 16 and the first slide groove 17 on the connecting plate 12 will gradually decrease. When the pressure rod 43 cannot move, the friction between the connecting plate 12 and the speaker body 1 is at a minimum state. At this time, the user can easily remove the connecting plate 12 from the surface of the speaker body 1; pressing the pressure rod 43 can make the top plate 44 push the first slider 16 to move along the first slide groove 17, so that the connecting plate 12 and the speaker body 1 will be separated, thereby improving the convenience of disassembling the connecting plate 12 and shortening the time required for disassembling the connecting plate 12.

[0038] See also Figure 6 As shown, a plurality of cross bars 52 are fixedly connected to the inner side wall of the second spring 42; a first elastic rod 5 is fixedly connected to the middle part of the top plate 44; the first elastic rod 5 and the cross bar 52 are in contact with each other; during normal operation, the first elastic rod 5 will contact the cross bar 52, and when the first slider 16 enters the first slide groove 17, the first slider 16 will contact the first elastic rod 5, and the first elastic rod 5 will bend under the squeezing action of the cross bar 52 and the first slider 16 and squeeze the side wall of the first slider 16, so that the first slider 16 will squeeze the first slide groove 17, increase the positive pressure of the first slider 16 on the first slide groove 17, increase the friction between the first slider 16 and the first slide groove 17, and improve the stability of the connecting plate 12 when it is fixed on the top of the speaker body 1.

[0039] See also Figures 1 to 10As shown, the bottom of the speaker body 1 is rotatably connected to a first connecting belt 6; a second slide groove 63 is opened in the middle of the first connecting belt 6; the bottom of the speaker body 1 is rotatably connected to a second connecting belt 62; the second connecting belt 62 and the second slide groove 63 are correspondingly arranged and slidably matched; the first connecting belt 6 and the second connecting belt 62 are made of breathable material, and the user can wrap the first connecting belt 6 and the second connecting belt 62 around the arm when using the speaker body 1, and then insert the second connecting belt 62 into the second slide groove 63 so that friction will be generated between the first connecting belt 6 and the second connecting belt 62. When the first connecting belt 6 and the second connecting belt 62 completely fit the user's arm, the speaker body 1 will also be fixed on the user's arm, further improving the convenience of carrying the speaker body 1, so that the user can use the speaker body 1 more easily when exercising.

[0040] See also Figure 7 As shown, a pair of sponges 7 are fixedly connected to the inner wall of the second slide groove 63; the sponges 7 are symmetrically arranged; when the user wears the speaker body 1 to exercise, sweat will be generated on the arm, and the sweat will enter the interior of the sponge 7 through the first connecting belt 6 and be absorbed by the sponge 7, reducing the discomfort caused by sweat when the user wears the speaker body 1. At the same time, the second connecting belt 62 will squeeze the sponge 7 after entering the second slide groove 63, and the sponge 7 will fill the gap between the second slide groove 63 and the second connecting belt 62, further improving the stability of the connection between the second connecting belt 62 and the first connecting belt 6.

[0041] See also Figure 7 and Fig. 9 As shown, a plurality of circular plates 8 are fixedly connected to the middle part of the second connecting belt 62; a plurality of circular grooves 82 are opened in the middle part of the sponge 7; the circular plates 8 and the circular grooves 82 are correspondingly arranged and slidably matched; when the second connecting belt 62 enters the second slide groove 63, it will move with the circular plates 8, and the circular plates 8 will also enter the second slide groove 63 and contact the circular grooves 82 on the surface of the sponge 7. When the user pulls the second connecting belt 62 out of the second slide groove 63, the circular plates 8 will squeeze the circular grooves 82 and the sponge 7, so that the sweat inside the sponge 7 will be discharged, thereby reducing the residual sweat inside the sponge 7 and accelerating the drying speed of the sponge 7.

[0042] See also Figures 8 to 10As shown, a plurality of protrusions 9 are symmetrically fixed to the middle part of the second connecting belt 62; the end of the protrusion 9 is an arc-shaped transition; the inner side wall of the second slide groove 63 is provided with a plurality of grooves 92; the grooves 92 and the protrusions 9 are correspondingly arranged and are slidably matched; when the second connecting belt 62 enters the second slide groove 63, it will move with the protrusion 9, and the protrusion 9 will also enter the second slide groove 63 and contact the groove 92. Because the end of the protrusion 9 is an arc-shaped transition, the protrusion 9 will pass through several grooves 92 when it moves under the pressure of the user. When the protrusion 9 enters and disengages from the groove 92, the second connecting belt 62 will pause when moving, so that the user can quickly receive feedback when adjusting the first connecting belt 6 and the second connecting belt 62. When the second connecting belt 62 is adjusted to a suitable position, the protrusion 9 will enter the groove 92, so that the second connecting belt 62 and the second slide groove 63 are subjected to the friction of the protrusion 9 and the groove 92, further enhancing the stability of the connection between the first connecting belt 6 and the second connecting belt 62.

[0043] See also Fig.10 As shown, a plurality of second elastic rods 101 are fixedly connected to the middle part of the protrusion 9; an anti-skid pad 102 is fixedly connected to the middle part of the second elastic rod 101; in a normal state, the second elastic rod 101 is in a bent state, and when the second connecting belt 62 is adjusted, the protrusion 9 will enter the groove 92, and when the protrusion 9 moves, it will also move with the second elastic rod 101 and the anti-skid pad 102, and the second elastic rod 101 and the anti-skid pad 102 will enter the groove 92 and be squeezed by the groove 92, and the anti-skid pad 102 will contact the second slide groove 63 and generate friction, and the second elastic rod 101 will bend under the action of pressure and exert pressure on the anti-skid pad 102, so that positive pressure is generated between the anti-skid pad 102 and the second slide groove 63 and the friction is increased, thereby increasing the friction between the protrusion 9 and the groove 92, and further improving the stability of the second connecting belt 62 located inside the first connecting belt 6.

[0044] Working principle: when the speaker body 1 needs to be placed in a dustproof manner, the user can align the connecting plate 12 along the first slider 16 and the first slide groove 17, and then insert the connecting plate 12 into the top of the speaker body 1. The connecting plate 12 will cause the first slider 16 to enter the first slide groove 17 and generate friction, so that the connecting plate 12 is fixed to the top of the speaker body 1. Then the user can rotate the outer gear ring 13 to make the outer gear ring 13 rotate. When the outer gear ring 13 rotates, it will mesh with the gear 14 and make the gear 14 rotate. When the gear 14 rotates, it will drive the baffle 15 to move together. When the adjacent baffles 15 move, they will approach each other. During the process of the baffles 15 approaching, the gap between them will gradually shrink until the adjacent baffles 15 are close to each other. When the baffles 15 are in contact, a closed shape is formed to achieve dustproof treatment for the speaker body 1; when the baffles 15 are close to each other, the distance between the first fixing groove 2 and the second fixing groove 24 will also be close. During the movement of the baffle 15, the distance between the first magnet 25 and the second magnet 26 will gradually decrease. The first magnet 25 will be attracted by the second magnet 26, so that the slide plate 23 will slide along the first fixing groove 2 and enter the second fixing groove 24 under the magnetic force of the first magnet 25 and the second magnet 26. Because the depth of the second fixing groove 24 is less than the thickness of the slide plate 23, the slide plate 23 will fill the second fixing groove 24 and the gap between the first fixing groove 2 and the second fixing groove 24; when the slide plate 2 When the connecting plate 12 is disassembled, the user can press the pressure rod 43 to make the pressure rod 43 slide along the speaker body 1. When the pressure rod 43 moves, the second spring 42 is in a stretched state. At the same time, the pressure rod 43 pushes the top plate 44 to move along the cavity 4 and enter the first slide groove 17. When the top plate 44 moves, its bottom part contacts the first slider 16 and makes the first slider 16 move along the surface of the top plate 44. Because the top plate 44 is a trapezoidal structure, the first slider 16 will slowly rise along the first slide groove 17. At this time, the friction between the first slider 16 and the first slide groove 17 on the connecting plate 12 will gradually decrease. When the pressure rod 43 cannot move, the friction between the connecting plate 12 and the speaker body 1 is at a minimum state. At this time, the user can easily remove the connecting plate 12 from the surface of the speaker body 1; when the first slider 16 enters the first slide groove 17, the first slider 16 will contact the first elastic rod 5. The first elastic rod 5 will bend under the squeezing action of the cross bar 52 and the first slider 16 and squeeze the side wall of the first slider 16, so that the first slider 16 will squeeze the first slide groove 17;When the user uses the speaker body 1, the first connecting belt 6 and the second connecting belt 62 can be wrapped around the arm, and then the second connecting belt 62 can be inserted into the second slide groove 63 so that friction is generated between the first connecting belt 6 and the second connecting belt 62. When the first connecting belt 6 and the second connecting belt 62 completely fit the user's arm, the speaker body 1 will also be fixed on the user's arm; when the user wears the speaker body 1 for exercise, sweat will be generated on the arm, and the sweat will enter the sponge 7 through the first connecting belt 6 and be absorbed by the sponge 7, thereby reducing the sweat generated when the user wears the speaker body 1. When the second connecting belt 62 enters the second chute 63, it will squeeze the sponge 7, and the sponge 7 will fill the gap between the second chute 63 and the second connecting belt 62; when the second connecting belt 62 enters the second chute 63, it will move with the circular plate 8, and the circular plate 8 will also enter the second chute 63 and contact the circular groove 82 on the surface of the sponge 7. When the user pulls the second connecting belt 62 out of the second chute 63, the circular plate 8 will squeeze the circular groove 82 and the sponge 7, so that the sweat inside the sponge 7 will be discharged; when the second connecting belt 62 enters the second chute 63, the circular plate 8 will squeeze the circular groove 82 and the sponge 7, so that the sweat inside the sponge 7 will be discharged. When the second connecting belt 62 is adjusted to a suitable position, the protrusion 9 will enter the groove 92, so that the second connecting belt 62 and the second chute 63 can be moved together. The second connecting belt 62 is subjected to the friction between the protrusion 9 and the groove 92; when the second connecting belt 62 is adjusted, the protrusion 9 will enter the groove 92, and the protrusion 9 will also move with the second elastic rod 101 and the anti-skid pad 102, and the second elastic rod 101 and the anti-skid pad 102 will enter the groove 92 and be squeezed by the groove 92, and the anti-skid pad 102 will contact and generate friction with the second slide groove 63, and the second elastic rod 101 will bend under the pressure and exert pressure on the anti-skid pad 102, so that positive pressure is generated between the anti-skid pad 102 and the second slide groove 63 and the friction is increased. ;
