[0026] Reference Figure 1 A broadcasting device includes: a first loudspeaker 100, a second loudspeaker 200, a guiding structure 300, and a locking structure 500. The second loudspeaker 200 is movably connected to the first loudspeaker 100, and the first loudspeaker 100 and the second loudspeaker 200 are electrically connected and capable of synchronously playing sound. The first loudspeaker 100 and the second loudspeaker 200 are connected through the guiding structure 300, and at least one of the first loudspeaker 100 and the second loudspeaker 200 is movable relative to the guiding structure 300, causing the first loudspeaker 100 and the second loudspeaker 200 to move closer to or further away from each other. The locking structure 500 is used to relatively fix the first loudspeaker 100 and the second loudspeaker 200. The first loudspeaker 100 and the second loudspeaker 200 can synchronously play sound at different positions, thereby effectively achieving a stereo broadcasting effect, and thus providing a good audio-visual experience in conjunction with video playback equipment. When the broadcast position needs to be adjusted, the guide structure 300 can drive at least one of the first loudspeaker 100 and the second loudspeaker 200 to move, thereby creating a relative displacement between them. The locking structure 500 then fixes the relative distance between the first loudspeaker 100 and the second loudspeaker 200. By adjusting the distance between the first loudspeaker 100 and the second loudspeaker 200, various broadcast position requirements within a scene can be accommodated, effectively achieving the effect of adapting to broadcast needs in different scenarios.

[0027] In some embodiments, reference is made to Figure 1The guide structure 300 includes a connecting rod 310. A first loudspeaker 100 and a second loudspeaker 200 are respectively connected to both ends of the connecting rod 310. At least one of the first loudspeaker 100 and the second loudspeaker 200 can slide relative to the connecting rod 310. A locking structure 500 is installed on the connecting rod 310 and can fix the connecting rod 310 and the first loudspeaker 100 and the second loudspeaker 200 to each other. The connecting rod 310 not only connects the first loudspeaker 100 and the second loudspeaker 200, but also guides their relative movement. When the first loudspeaker 100 and the second loudspeaker 200 move relative to each other, they will slide along the length of the connecting rod 310, making the movement between the first loudspeaker 100 and the second loudspeaker 200 more intuitive and stable. Furthermore, the connecting rod 310 can also position the locking structure 500, thereby facilitating its obstruction of the first loudspeaker 100 or the second loudspeaker 200, and thus achieving the effect of relatively fixing the first loudspeaker 100 and the second loudspeaker 200.

[0028] Specifically, the connecting rod 310 is a cylinder. Of course, the connecting rod 310 can also be a polygonal prism, thus preventing the first loudspeaker 100 and the second loudspeaker 200 from rotating. Specific implementation methods can be adjusted according to actual needs and are not limited here.

[0029] In some embodiments, reference is made to Figure 1 The guide structure 300 includes a support rod 320, a connecting rod 310, and the support rod 320, which are respectively connected to both sides of the first loudspeaker 100. The connecting rod 310 and the support rod 320 are respectively connected to both sides of the second loudspeaker 200. At least one of the first loudspeaker 100 and the second loudspeaker 200 can slide relative to the support rod 320. The support rod 320 can cooperate with the connecting rod 310 to support both sides of the first loudspeaker 100 and the second loudspeaker 200, thereby preventing them from tilting to the side when they move relative to each other, and ensuring that the first loudspeaker 100 and the second loudspeaker 200 can always maintain a stable connection.

[0030] In some embodiments, reference is made to Figure 1Multiple support rods 320 are connected to the left and right sides of the first loudspeaker 100 and the second loudspeaker 200, respectively. Support rods 320 and connecting rods 310 are connected to the upper and lower sides of the first loudspeaker 100 and the second loudspeaker 200, respectively. The support rods 320 and connecting rods 310 connect the first loudspeaker 100 and the second loudspeaker 200 from the upper and lower sides, while multiple support rods 320 connect the first loudspeaker 100 and the second loudspeaker 200 from the left and right sides. Therefore, the first loudspeaker 100 and the second loudspeaker 200 can be interconnected in multiple ways, effectively preventing misalignment between them.

[0031] Specifically, there are two support rods 320, which are respectively connected to the left and right sides of the first loudspeaker 100 and the second loudspeaker 200.

[0032] In some embodiments, reference is made to Figure 2 The first loudspeaker 100 and / or the second loudspeaker 200 are provided with a movable cavity 150, and the connecting rod 310 extends into the movable cavity 150. The movable cavity 150 is provided with a push spring 350, which can drive the connecting rod 310 to move away from the movable cavity 150 through its elastic force. The locking structure 500 is provided outside the movable cavity 150. The movable cavity 150 ensures that the connecting rod 310 can extend and retract relative to the first loudspeaker 100 and the second loudspeaker 200 during movement, thereby providing room for relative movement between the connecting rod 310 and the first loudspeaker 100 and the second loudspeaker 200. The push spring 350 and the locking structure 500 can apply force to the first loudspeaker 100 / second loudspeaker 200 from both the inside and outside of the movable cavity 150. As a result, the first loudspeaker 100 / second loudspeaker 200 will be clamped together by the push spring 350 and the locking structure 500, and can be fixed in the direction toward either end of the connecting rod 310. This ensures that the distance between the first loudspeaker 100 and the second loudspeaker 200 can be fixed in all states.

[0033] Specifically, both the first loudspeaker 100 and the second loudspeaker 200 are provided with a movable cavity 150, and each movable cavity 150 is provided with a push spring 350. The specific implementation method can be adjusted accordingly according to actual needs, and is not limited here.

[0034] In some embodiments, reference is made to Figure 2Both the first loudspeaker 100 and the second loudspeaker 200 can slide relative to the connecting rod 310. There are two locking structures 500; one of them prevents the first loudspeaker 100 from moving relative to the connecting rod 310, and the other prevents the second loudspeaker 200 from moving relative to the connecting rod 310. Since both the first loudspeaker 100 and the second loudspeaker 200 can slide, their relative distance can be easily adjusted. The two locking structures 500 can respectively fix the first loudspeaker 100 and the second loudspeaker 200, ensuring that either one remains fixed after movement, thus facilitating the determination of the distance between them.

[0035] In some embodiments, reference is made to Figure 3 The locking structure 500 includes a stop seat 510 sleeved on the outer periphery of the connecting rod 310. The stop seat 510 is provided with a fastening clamp 520 sleeved on the outer periphery of the connecting rod 310. The fastening clamp 520 can retract to clamp the connecting rod 310 or extend to release the connecting rod 310. The stop seat 510 can abut against the first loudspeaker 100 or the second loudspeaker 200 through its end and prevent its movement. After the fastening clamp 520 retracts and clamps the connecting rod 310, the stop seat 510 will be fixed relative to the connecting rod 310. Thus, the stop seat 510 can block the first loudspeaker 100 or the second loudspeaker 200, thereby facilitating the fixation of the first loudspeaker 100 or the second loudspeaker 200.

[0036] In some embodiments, reference is made to Figure 4 The fastening clamp 520 is elastic and has a deformation notch 525. When the fastening clamp 520 is compressed, it can elastically contract and narrow the deformation notch 525. The stop seat 510 is connected to a movable part 550 that can move to compress the fastening clamp 520 or move away from the fastening clamp 520. The elastic fastening clamp 520 can automatically recover after the movable part 550 moves away and relax the connecting rod 310. Therefore, by driving the movable part 550 to move closer to or away from the fastening clamp 520, the stop seat 510 can be directly and effectively fixed or unfixed, thereby facilitating the stop seat 510 to obstruct and position the first loudspeaker 100 and the second loudspeaker 200.

[0037] In some embodiments, reference is made to Figure 4The stop seat 510 is provided with a threaded section 515, and the fastening clamp 520 is installed on the threaded section 515 with a deformation notch 525 extending outward relative to the threaded section 515. The movable part 550 is threadedly connected to the threaded section 515 and can move relative to it. The threaded connection between the fastening clamp 520 and the threaded section 515 not only allows the fastening clamp 520 to move more stably relative to the movable part 550, but also allows the movable part 550 to tend to move axially relative to the threaded section 515 due to the elastic push of the fastening clamp 520. This allows the movable part 550 to spontaneously tighten against the threaded section 515 without operation, thus preventing the stop seat 510 from loosening due to accidental movement of the movable part 550.

[0038] In some embodiments, reference is made to Figure 4 Both the movable component 550 and the fastening clamp 520 are provided with inclined surfaces 530. When the movable component 550 moves closer to the fastening clamp 520, it can push the fastening clamp 520 through the inclined surfaces 530. The inclined surfaces 530 are inclined towards the central axis of the connecting rod 310. When the movable component 550 moves to push the fastening clamp 520, the inclined surfaces 530 will apply a force to the fastening clamp 520 in the direction of the central axis of the connecting rod 310, thereby forcing the fastening clamp 520 to elastically contract. This can achieve the effect of clamping and fixing the connecting rod 310 and the stop seat 510 together through the fastening clamp 520.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
