[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figure 1-3 A full-frequency floor speaker for multiple scenes includes a box body 1, a through slot 3 is arranged inside the box body 1, two grabbing devices 4 are arranged inside the through slot 3, and the two grabbing devices 4 are used to fix the box body 1. A button 8 is also installed at the lower end of the box body 1. A driving device 5 is installed inside the box body 1. The button 8 is electrically connected to the driving device 5, and the driving device 5 is used to drive the grabbing device 4 to rotate;

[0042] The two grasping devices 4 each include a first rod 41 and a second rod 44 installed inside the box body 1, a squeezing plate 45 is installed at the lower end of the second rod 44, a connecting plate 42 is installed at the lower end of the first rod 41, a first piston chamber 12 is arranged inside the connecting plate 42, a first piston column 11 is slidably connected to the lower end of the first piston chamber 12, an arc plate 43 is installed at the lower end of the first piston column 11, a first tube 10 is installed at one end of the connecting plate 42, a cylinder 46 is also installed inside the box body 1, one end of the first tube 10 is connected to the inside of the cylinder 46, a second piston column 47 is slidably connected to the inside of the cylinder 46, a suction cup 48 is installed at the lower end of the second piston column 47, and a magnet 49 is installed at the lower end of the suction cup 48;

[0043] A first spring 13 is also installed at the upper end of the arc plate 43 , and the connecting plate 42 is connected to the arc plate 43 via the first spring 13 . A third spring 50 is installed on the outer surface of the second piston column 47 , and the second piston column 47 is connected to the cylinder 46 via the third spring 50 .

[0044] according to Figure 1 and Figure 2 As shown, by relatively rotating the first rod 41 and the second rod 44, the first rod 41 and the second rod 44 drive the arc plate 43 and the extrusion plate 45 to relatively rotate, and the rotated arc plate 43 and the extrusion plate 45 protrude from the lower end surface of the box body 1, so that the first rod 41 and the extrusion plate 45 can be rotated and inserted into the ground, so that the box body 1 can be fixed on the ground;

[0045] When the landing scene is a hard ground, when the arc plate 43 contacts the hard ground, the hard ground will squeeze the arc plate 43 to slide upward, and the arc plate 43 drives the first piston column 11 to slide upward, and the first piston column 11 squeezes the liquid inside the first piston chamber 12 to the first tube 10. Figure 3As shown, the liquid is squeezed to the upper end of the second piston column 47 through the first tube 10, and the second piston column 47 is squeezed by the liquid to slide downward, and the second piston column 47 drives the suction cup 48 to contact the hard ground, so that the hard ground is adsorbed by the negative pressure of the suction cup 48. When an iron wall and floor are needed, the magnet 49 inside the suction cup 48 is magnetically attracted and adhered to the iron wall and floor, so that the box 1 is fixed on the hard ground, thereby realizing multi-scene use.

[0046] Example 2

[0047] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-4 In this embodiment, a balancing device 6 is installed inside the box 1, and the balancing device 6 is used to adjust the center of gravity of the box 1;

[0048] The balancing device 6 includes a first counterweight block 61 and a second counterweight block 64 which are slidably connected to the inside of the box body 1;

[0049] A first spring rope 62 is installed at one end of the first counterweight block 61, and a third spring rope 67 is installed at the other end of the first counterweight block 61;

[0050] A second spring rope 65 is installed at one end of the second counterweight 64 , and a fourth spring rope 68 is installed at the other end of the second counterweight 64 .

[0051] When the support conditions of the installation scene are limited, the floor-standing speaker may have an unstable center of gravity, causing the floor-standing speaker to tip over. Therefore, a second counterweight block 64 and a first counterweight block 61 are slidably arranged inside the box body 1. Figure 4 As shown, the second counterweight block 64 and the first counterweight block 61 are respectively arranged at the upper ends of the two grabbing devices 4. When the grabbing device 4 on the left side is in contact with the ground and the grabbing device 4 on the right side has no support, the first counterweight block 61 and the first spring rope 62 are slid to the left so that the first counterweight block 61 and the first spring rope 62 are located at the upper end of the left grabbing device 4, thereby increasing the weight at the left grabbing device 4, thereby changing the center of gravity of the box body 1 and bringing the center of gravity of the box body 1 close to the supporting grabbing device 4, thereby reducing the risk of the box body 1 tipping over.

[0052] Example 3

[0053] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-4 In this embodiment, the interior of the box body 1 is rotatably connected with a first winding column 63 and a second winding column 66;

[0054] The second spring rope 65 and one end of the first spring rope 62 are connected to the first winding post 63;

[0055] One end of the third spring rope 67 and the fourth spring rope 68 are connected to the second winding post 66;

[0056] The driving device 5 is also used to drive the first winding post 63 and the second winding post 66 to rotate.

[0057] The box body 1 is provided with a roller, on which the first counterweight 61 and the second counterweight 64 are in contact. The box body 1 is also provided with four guide pulleys, which are respectively arranged at the lower ends of the first spring rope 62, the second spring rope 65, the third spring rope 67 and the fourth spring rope 68.

[0058] according to Figure 4 As shown, the first winding column 63 and the second winding column 66 are driven to rotate by the driving device 5. When the left gripping device 4 supports the ground, the left gripping device 4 sends a signal to the first winding column 63, so that the first winding column 63 rotates, and the second spring rope 65 and the first spring rope 62 are pulled by the first winding column 63 to be wound on the outer surface of the first winding column 63, so that the second spring rope 65 and the first spring rope 62 pull the first counterweight block 61 and the second counterweight block 64 to slide to the left side;

[0059] When the right gripping device 4 supports the ground, the side gripping device 4 sends a signal to the second winding column 66, so that the second winding column 66 rotates, and the third spring rope 67 and the fourth spring rope 68 are pulled by the second winding column 66 to be wound around the outer surface of the second winding column 66, so that the third spring rope 67 and the fourth spring rope 68 pull the first counterweight block 61 and the second counterweight block 64 to slide to the right;

[0060] In summary, the center of gravity inside the box 1 can be changed according to the actual support position;

[0061] It should be noted that the second spring rope 65, the first spring rope 62, the third spring rope 67 and the fourth spring rope 68 all have elastic force, so that the pull rope can be extended;

[0062] By installing pressure sensors inside the arc plate 43 and the suction cup 48, when the arc plate 43 is inserted into the ground or the suction cup 48 hits the ground, the pressure sensor will be triggered, thereby sending a signal to the first winding column 63 and the second winding column 66 through the pressure sensor, so that the first winding column 63 or the second winding column 66 can rotate. When the pressure sensors of the two grasping devices 4 are triggered, it means that the ground at the lower end of the box body 1 can fully support the box body 1, so the pressure sensor will not send a signal to the first winding column 63 and the second winding column 66.

[0063] Example 4

[0064] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-5In this embodiment, the driving device 5 includes a motor 51 mounted on the inner wall of the box body 1, and a main gear 59 is mounted on one end of the motor 51;

[0065] An adjusting component is installed at one end of the first winding column 63 and the second winding column 66. The adjusting component includes a piston cylinder 57, an L-shaped groove 55, a piston plate 56, a square column 54 and a return spring 58. The piston cylinder 57 is slidably connected with the piston plate 56. The square column 54 is installed at one end of the piston plate 56. The square column 54 passes through one end of the piston cylinder 57. The square column 54 is provided with an L-shaped groove 55. A driven gear 52 is installed at one end of the square column 54. The main gear 59 is used to mesh with the driven gear 52. A return spring 58 is installed between the piston cylinder 57 and the driven gear 52.

[0066] One end of the driven gear 52 is rotatably connected to the second tube 14;

[0067] The two arc plates 43 are provided with an arc cavity 17 inside, and the arc plate 15 is slidably connected inside the arc cavity 17. One end of the arc plate 15 passes through the lower end of the arc plate 43, and the extrusion plate 45 is used to squeeze the arc plate 15 to slide;

[0068] One ends of the two second tubes 14 are communicated with the interiors of the two arc-shaped cavities 17 .

[0069] according to Figure 5 and Figure 6 As shown, when the arc plate 43 and the lower end of the squeezing plate 45 of the left end grabbing device 4 are suspended in the air, the two arc plates 43 and the squeezing plate 45 rotate relative to each other, so that the squeezing plate 45 abuts against the arc plate 15, thereby squeezing the arc plate 15 to slide through the squeezing plate 45, and the arc plate 15 squeezes the liquid inside the arc cavity 17, and the liquid enters the piston cylinder 57 at one end of the first winding column 63 through the second tube 14, and the liquid flows into one end of the piston plate 56 through the L-shaped groove 55, so that the liquid pushes the piston plate 56 to slide to one end, and the piston plate 56 pulls the square column 54 to slide to one end, so that the driven gear 52 and the main gear 5 9 is meshed, the main gear 59 is driven to rotate by the motor 51, the main gear 59 drives the driven gear 52 to rotate, the driven gear 52 drives the square column 54 to rotate, the square column 54 drives the piston cylinder 57 and the first winding column 63 to rotate, so that the first winding column 63 is pulled to the second spring rope 65 and the first spring rope 62 are wound on the outer surface of the first winding column 63, so that the second spring rope 65 and the first spring rope 62 pull the first counterweight block 61 and the first spring rope 62 to slide leftward, so that the first counterweight block 61 and the first spring rope 62 are located at the upper end of the left grabbing device 4, thereby increasing the weight at the left grabbing device 4;

[0070] When the arc plate 43 of the right end grabbing device 4 and the lower end of the extrusion plate 45 are suspended in the air, the working principle is the same as above. Figure 6As shown, the driven gear 52 of the right end grabbing device 4 is meshed with the main gear 59, the main gear 59 drives the second winding column 66 to rotate, and the second winding column 66 pulls the third spring rope 67 and the fourth spring rope 68 to be wound on the outer surface of the second winding column 66, so that the third spring rope 67 and the fourth spring rope 68 pull the first counterweight block 61 and the first spring rope 62 to slide rightward, so that the first counterweight block 61 and the first spring rope 62 are located at the upper end of the right side grabbing device 4, thereby increasing the weight at the left side grabbing device 4;

[0071] It should be noted that according to Figure 5 As shown, the squeezing plate 45 is made of elastic material and can be deformed. Therefore, when the lower ends of the two grabbing devices 4 are supported by the ground, the hard ground will squeeze the squeezing plate 45 to deform, so that the squeezing plate 45 will not squeeze the arc plate 15 to slide upward, and the squeezing plate 45 and the arc plate 43 are interlaced with each other;

[0072] It should be noted that according to Figure 5 As shown, when the ground is soil, the spring force of the spring piece 16 is relatively large, so when the arc plate 43 is inserted into the soil from the inside of the box body 1, the soil will not squeeze the spring piece 16 to slide, and the length of the arc plate 43 will not be inserted into the hard soil.

[0073] Example 5

[0074] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-7 In this embodiment, a first gear 24 is mounted on one end of the first rod 41, a second gear 25 is mounted on one end of the second rod 44, and the second gear 25 is meshed with the first gear 24;

[0075] A pushing component is also installed inside the box body 1, and the main gear 59 is used to drive the pushing component to slide, and the pushing component drives the first gear 24 to rotate;

[0076] The pushing component includes a second rack 22, which is slidably connected to the inside of the box 1, and is used to drive the two first gears 24 to rotate;

[0077] One end of the second rack 22 is slidably connected to the first rack 21, and the lower end of the first rack 21 is meshed with the main gear 59;

[0078] The second rack 22 is connected to the first rack 21 via a second spring 23 .

[0079] When the box body 1 is placed on the ground, the ground will first squeeze the button 8, so that the button 8 sends a signal to the motor 51, so that the motor 51 is powered on and rotates, and the motor 51 rotates clockwise, and the motor 51 drives the main gear 59 to rotate, and the main gear 59 drives the first rack 21 to slide to the right, so that the first rack 21 drives the two first gears 24 to rotate, and the two first gears 24 drive the second gear 25 to rotate, so that the first gear 24 and the second gear 25 drive the first rod 41 and the second rod 44 to rotate, and the arc plate 43 and the extrusion plate 45 are driven to rotate by the first rod 41 and the second rod 44, so that the arc plate 43 and the extrusion plate 45 can be inserted into the ground, and the arc plate 43 is used to detect whether the ground is suspended. When the lower end of the arc plate 43 is suspended, the liquid in the arc cavity 17 will enter the piston cylinder 57, thereby adjusting the position of the driven gear 52 at one end of the first winding column 63 or the second winding column 66, so as to selectively drive the first winding column 63 and the second winding column 66 to rotate.
