[0002] With the increasing prevalence of outdoor public activities, loudspeaker systems have become indispensable equipment for events such as square dancing, outdoor performances, and group gatherings. These systems, with their powerful sound output capabilities, can meet the sound coverage requirements of large spaces, providing strong sound support for various outdoor activities. Existing devices typically have wheels installed at the bottom. While these allow for some movement on flat ground, they are less effective on uneven terrain such as steps or slopes. This often requires manual labor to move the device, increasing the user's physical burden and increasing the risk of damage during transport. As a result, these devices cannot meet the need for convenient movement in complex outdoor environments.

[0003] Therefore, a loudspeaker device was designed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a loudspeaker device. It solves the problem that although existing devices are equipped with wheels at the bottom for movement on flat ground, the wheels fail when facing uneven terrain such as steps or slopes, requiring manual labor for carrying. This increases the physical burden on users and makes the device prone to damage from bumps and knocks, failing to meet the need for convenient movement in complex outdoor environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A loudspeaker device includes a loudspeaker body, with rotating rods fixedly installed on both sides of the loudspeaker body. Movable components are rotatably installed on the outer walls of the two rotating rods, and three sets of movable wheels are fixedly installed on the outer walls of the movable components. Mounting components for fixing the movable wheels are also movably installed on the outer walls of the movable components.

[0006] Preferably, a telescopic rod is provided on the top of the speaker body, a vertical plate is fixedly installed on the bottom of the speaker body, and three sets of mounting brackets are fixedly installed on the outer wall of the moving part, the three sets of mounting brackets being designed in a triangle.

[0007] Preferably, the installed component includes a cylinder, which is fixedly connected to a corresponding mounting bracket, and the cylinder has a movable groove inside, which penetrates the cylinder.

[0008] Preferably, two locking blocks are slidably installed inside the movable groove, and the two cylinders are elastically connected by springs on the sides that are close to each other.

[0009] Preferably, each of the two locking blocks has a portion extending out of the cylinder, and the portion of the locking block extending out of the cylinder abuts against the moving wheel.

[0010] Preferably, the inner walls of the two movable slots away from the spring are respectively designed to be inclined, and a T-shaped rod is provided inside the end of the cylinder away from the mounting bracket. The outer wall of the T-shaped rod is threaded, and the T-shaped rod is threaded to the cylinder through the thread on the outer wall.

[0011] Preferably, a retaining bead is fixedly installed at one end of the T-shaped rod inside the cylinder, and the retaining bead abuts against both retaining blocks.

[0012] Preferably, the movable wheel includes an inner shaft that is slidably connected to a cylinder and is fixed to the cylinder by abutting against two locking blocks.

[0013] Preferably, a connecting piece is fixedly installed on the outer wall of the inner shaft, the outer wall of the connecting piece has honeycomb-shaped openings, and an outer ring is fixedly installed on the outer wall of the connecting piece.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention solves the problem of traditional outdoor speakers being difficult to move on uneven terrain by setting up a movable component that is rotatably connected to the speaker body via a rotating rod, along with three sets of triangular mounting brackets and casters. This allows the device to be easily moved on flat ground by pulling out a telescopic rod, and also to move smoothly on steps and other complex terrains by using the rotation of the movable component.

[0023] Example 1: Please see Figure 1-6A loudspeaker device includes a loudspeaker body 1. A telescopic rod 11 is provided on the top of the loudspeaker body 1. When the loudspeaker body 1 needs to be placed, a vertical plate 12 contacts the bottom surface and forms support. The vertical plate 12 is fixedly installed at the bottom of the loudspeaker body 1. Rotating rods 13 are fixedly installed on both sides of the loudspeaker body 1. Moving parts 2 are rotatably installed on the outer walls of the two rotating rods 13. Three sets of moving wheels 4 are fixedly installed on the outer walls of the moving parts 2, and mounting parts 3 for fixing the moving wheels 4 are also movably installed on the outer walls of the moving parts 2. Three sets of mounting brackets 21 are fixedly installed on the outer walls of the moving parts 2, and the three sets of mounting brackets 21 are triangularly designed. The mounting parts 3 include a cylinder 31, which is fixedly connected to the corresponding mounting bracket 21. A movable groove 311 is opened inside the cylinder 31, penetrating the cylinder 31. Two locking blocks 32 are slidably installed inside the movable groove 311. The cylinders 31 are elastically connected at their close sides by springs 33; each of the two locking blocks 32 extends beyond the cylinder 31, and the extended portions of the locking blocks 32 abut against the moving wheel 4; the inner walls of the two movable grooves 311 away from the springs 33 are respectively designed to be inclined; a T-shaped rod 34 is provided inside the end of the cylinder 31 away from the mounting bracket 21, and a thread 341 is provided on the outer wall of the T-shaped rod 34, through which the T-shaped rod 34 is threaded with the cylinder 31. The T-shaped rod 34 is connected to the cylinder 31. A retaining bead 3411 is fixedly installed at one end of the T-shaped rod 34 inside the cylinder 31. The retaining bead 3411 abuts against two retaining blocks 32. The movable wheel 4 includes an inner shaft 41, which is slidably connected to the cylinder 31 and fixed to the cylinder 31 by abutting against two retaining blocks 32. A connecting piece 43 is fixedly installed on the outer wall of the inner shaft 41. A honeycomb-shaped opening is formed on the outer wall of the connecting piece 43. An outer ring 44 is fixedly installed on the outer wall of the connecting piece 43. In another embodiment, two rings of connecting rods 42 are fixedly installed on the outer wall of the inner shaft 41. The connecting rods 42 are designed in a bent shape and the bending directions of the two rings of connecting rods 42 are opposite. The connecting rods 42 are made of soft rubber. The two sets of connecting rods 42 are arranged on both sides of the connecting piece 43. The outer ring 44 is fixedly connected to the other end of the two sets of connecting rods 42. The connecting piece 43 is made of hard rubber. The hardness value of the outer ring 44 is between that of the connecting piece 43 and the connecting rods 42.

[0024] By setting connecting rods 42 on both sides of the connecting piece 43, when the device is moving, if there are protruding foreign objects (such as small stones) on the ground and the foreign objects happen to be on the outer ring 44, the relatively soft connecting rods 42 will gradually release the foreign objects through bending, stretching and other deformation processes when encountering protruding foreign objects, which greatly reduces the hard impact of foreign objects on the edge of the outer ring 44 and the bottom connecting parts of the speaker. Both connecting rods 42 are designed to be evenly distributed with the axis of the inner shaft 41 as the center. The distance between two adjacent connecting rods 42 is greater than the honeycomb opening on the outer wall of the connecting piece 43 to prevent foreign objects from getting stuck between the connecting piece 43 and the connecting rods 42.

[0025] By setting the movable component 2 to be rotatably connected to the speaker body 1 via the rotating rod 13, and with three sets of triangular mounting brackets 21 and moving wheels 4, the device can not only be easily moved on flat ground by pulling out the telescopic rod 11, but also move smoothly on steps and other complex terrains by using the rotation of the movable component 2. This effectively solves the problem of traditional outdoor speakers being difficult to move on uneven terrain. By setting the vertical plate 12, the speaker body 1 can also be placed in contact with the bottom surface to form support. Together with the bottom vertical plate 12, the stability of the device when placed is enhanced, avoiding the risk of tipping over due to unstable placement. By rotating the T-shaped rod 34, the thread 341 on its outer wall is connected to the thread of the cylinder 31, which can drive the ball 3411 to move, thereby controlling the extension and retraction of the two blocks 32 in the movable groove 311; so that the inner shaft 41 of the movable wheel 4 can be easily installed on the cylinder 31. With two connecting rods 42 made of soft rubber and bent in opposite directions, a connecting piece 43 with honeycomb openings in the middle, and an outer ring 44 made of hard rubber, the soft rubber connecting rods 42 can effectively absorb vibrations during movement. The honeycomb openings of the connecting piece 43 further enhance the shock absorption effect, while the hard rubber outer ring 44 ensures the wear resistance and structural strength of the moving wheel 4, making the device more stable when moving and reducing the impact of vibrations on the internal components of the speaker.

[0026] Workflow When installing the movable wheel 4, first rotate the T-shaped rod 34 to move it outward along its own axis, which in turn moves the retaining ball 3411 inside the cylinder 31 along with the T-shaped rod 34 outward. Because the inner walls of the two retaining blocks 32 away from the spring 33 are designed to be inclined, when the retaining ball 3411 moves outward, it will slowly disengage from the inclined inner walls of the two retaining blocks 32. Under the elastic force of the spring 33, the two retaining blocks 32 retract inward and fit the inner shaft 41 on the movable wheel 4 onto the cylinder 31. Rotate the T-shaped rod 34 in the opposite direction to make the retaining ball 3411 slowly approach the two retaining blocks 32. With the help of the inclined design of the contact part between the retaining blocks 32 and the retaining ball 3411, the movement of the retaining ball 3411 will push the two retaining blocks 32 away from each other, at which time the spring 33 is stretched. When the two retaining blocks 32 move away from each other and protrude outward, the inner shaft 41 is fixed between the two retaining blocks 32 and the mounting bracket 21, completing the installation of the movable wheel 4. When movement is required on flat ground, the telescopic rod 11 is pulled out, causing the speaker body 1 and the telescopic rod 11 to tilt. The speaker body 1 can then be moved by the moving wheels 4. When encountering steps, since the moving part 2 and the rotating rod 13 are rotatably connected, the speaker body 1 can be moved on the steps by rotating the moving part 2. The connecting rod 42 inside the moving wheels 4 is made of soft rubber, and the outer wall of the connecting piece 43 is provided with honeycomb grooves, which effectively reduces the vibration generated by the moving wheels 4 during movement.
