[0001] This utility model relates to the technical field of speakers, and more particularly to a portable Bluetooth speaker. Background Technology

[0002] With the increasing popularity of outdoor camping, cycling, mountain climbing, and other leisure activities, portable Bluetooth speakers have become essential audio devices for consumers' outdoor activities due to their core advantages of wireless connectivity, compact size, light weight, and portability. To adapt to the diverse hanging needs of outdoor use (such as hanging on tent poles, backpack straps, tree trunks, etc.), existing portable Bluetooth speakers are usually equipped with lanyards to improve the flexibility of use in different scenarios, which is in line with their core positioning of "portable and easy to carry".

[0003] In related technologies, existing portable Bluetooth speakers use a lanyard design. In practical applications, this structure is difficult to adapt to diverse hanging needs. Most lanyards are of fixed length and cannot be adjusted according to the size of the hanging carrier (such as thickness and height). If they are too long, the speaker will shake and get tangled; if they are too short, they cannot be hung at all, resulting in poor adaptability. The few adjustable lanyards mostly use Velcro binding or simple sliding buckles, which have poor locking stability and are prone to loosening on their own due to vibration or tension, causing the speaker to fall and get damaged.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The portable Bluetooth speaker of this utility model embodiment will now be described with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, the portable Bluetooth speaker of this utility model embodiment may include a speaker body 1 and a suspension assembly 2.

[0018] It should be noted that a storage slot 11 is provided on one corner of the speaker body 1 described in this embodiment, and the protective shell 21 is assembled in the storage slot 11.

[0019] Specifically, a first strong magnet (not shown in the figure) is fixed inside the storage slot 11, and a second strong magnet (not shown in the figure) is fixed on both sides of the protective shell 21. When the user needs to replace the hanging rope 24, the suspension assembly 2 can be removed.

[0020] In one embodiment of this utility model, such as Figures 1 to 3 As shown, the suspension assembly 2 includes a protective shell 21, two reset structures 22, a limiting structure 23, and a suspension rope 24.

[0021] The protective shell 21 is mounted on the speaker body 1. Two reset structures 22 are both located inside the protective shell 21. A limiting structure 23 is located inside the protective shell 21 and limits the two reset structures 22. The two ends of the hanging rope 24 are respectively wrapped around the two reset structures 22, and the middle part extends to the outside of the protective shell 21.

[0022] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the reset structure 22 includes a rotating rod 221, a rotating wheel 222, a torsion spring 223, a first rotating plate 224, and a first locking block 225.

[0023] Two rotating rods 221 are respectively axially connected to the two sides of the inner wall of the protective shell 21. Two rotating wheels 222 are respectively set on the two rotating rods 221. Two torsion springs 223 are respectively sleeved on the two rotating rods 221, and their two ends are respectively connected to the opposite ends of the corresponding rotating wheels 222 and the two sides of the inner wall of the protective shell 21. Two first rotating plates 224 are respectively set on the opposite ends of the two rotating rods 221, and multiple first locking blocks 225 are evenly distributed in a ring on each first rotating plate 224.

[0024] As one possible scenario, according to one embodiment of the present invention, the top corner of the first locking block 225 is chamfered (not shown in the figure), so that when the second locking block 235 is reset, it can easily enter between every two first locking blocks 225 along the chamfer.

[0025] In one embodiment of this utility model, such as Figure 5 As shown, the limiting structure 23 includes a square shell 231, a pressing rod 232, a square block 233, a second rotating plate 234, a second locking block 235, a transmission rod 236, and an elastic element 237.

[0026] The square shell 231 is installed inside the protective shell 21 by a support rod and is located between the two first rotating plates 224. It has a sliding hole 2311 and through holes 2312 on both sides of the sliding hole 2311. The pressing rod 232 slides in the sliding hole 2311. The two square blocks 233 slide in the square shell 231 and are hinged to the pressing rod 232 by a transmission rod 236. The two second rotating plates 234 are respectively installed on the opposite sides of the two square blocks 233. Each second rotating plate 234 has a plurality of second locking blocks 235 evenly distributed in a ring. The second locking blocks 235 are adapted to the first locking blocks 225. The elastic element 237 is sleeved on the pressing rod 232 and its two ends are respectively connected to the square shell 231 and the protective shell 21.

[0027] It should be noted that the protective shell 21 has two first through holes 211 and a second through hole 212. The second through hole 212 is located between the two first through holes 211, and the pressing rod 232 passes through the second through hole 212 and extends to the outside of the protective shell 21.

[0028] Specifically, a baffle is provided on the end of the pressing rod 232 located on the outside of the protective shell 21 to prevent the pressing rod 232 from getting stuck inside the protective shell 21 after pressing.

[0029] It should be noted that the two ends of the suspension rope 24 are respectively wrapped around the two rotating wheels 222, and the middle part passes through the two first through holes 211 and extends to the outside of the protective shell 21.

[0030] Specifically, the suspension rope 24 is made of nylon rope, which has high tensile strength and excellent wear resistance. It is not easy to break or wear when repeatedly wound and stretched, which is suitable for the frequent adjustment of the suspension rope 24 and effectively extends its service life.

[0031] Specifically, when a user needs to hang this utility model, firstly, pressing the pressing rod 232 causes the two transmission rods 236 to rotate, thereby causing the two square blocks 233 to slide along the square shell 231 in opposite directions. This, in turn, causes the second rotating plate 234 and multiple second locking blocks 235 to gradually move away from the multiple first locking blocks 225. Secondly, pulling the middle part of the hanging rope 24 causes the winding end of the hanging rope 24 to gradually move away from the rotating wheel 222. At the same time, the rotating wheel 222 rotates, thereby driving the rotating rod 221 and the first rotating plate 234 to gradually move away from the rotating wheel 222. 24 and multiple first locking blocks 225 rotate, and at the same time, torsion spring 223 rotates under force. When the suspension rope 24 is pulled to a suitable length, the pressing rod 232 is released. At this time, due to the rebound of the elastic element 237, the pressing rod 232 is reset, which in turn drives the transmission rod 236, square block 233, second rotating plate 234 and multiple second locking blocks 235 to reset in sequence. Thus, multiple second locking blocks 235 limit multiple first locking blocks 225, preventing them from rotating. Finally, the utility model can be suspended by the suspension rope 24.

[0032] When the user needs to retract the suspension rope 24, pressing the pressing lever 232 causes the multiple second locking blocks 235 to move away from the multiple first locking blocks 225. Due to the rebound of the torsion spring 223, the rotating wheel 222, rotating rod 221, first rotating plate 224, and multiple first locking blocks 225 are rotated in sequence. The rotating wheel 222 causes the two ends of the suspension rope 24 to be wound around it. Finally, releasing the pressing lever 232 limits the multiple first locking blocks 225 through the multiple second locking blocks 235, preventing them from rotating.

[0033] In summary, the portable Bluetooth speaker of this utility model embodiment achieves precise extension and locking of the length of the suspension rope 24 through the linkage of the reset structure 22 and the limiting structure 23, and can be flexibly adjusted according to the size of different suspension carriers, completely solving the pain points of fixed length of existing suspension ropes 24, inconvenient adjustment or loose locking, and adapting to diverse outdoor scenarios.
