[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] like Figure 1 As shown, this embodiment proposes a portable multimedia speaker, which mainly includes a speaker body 1 and a moving mechanism 2. The speaker body 1 is located on the moving mechanism 2, that is, by means of the mobility of the moving mechanism 2, the speaker body 1 (the overall structure of this embodiment) is in a state that is easy to move.

[0028] Specifically, the moving mechanism 2 mainly includes a moving base 21, a protective shell 22, and several moving wheels 23. The protective shell 22 and each moving wheel 23 are fixedly connected to both ends of the moving base 21. That is, in this embodiment, the moving mechanism moves by means of the rolling of each moving wheel 23, so that the moving mechanism moves in a more labor-saving way. Each moving wheel 23 is preferably a universal wheel with a self-locking function, so that when the moving mechanism moves to the designated position, it can be fixed (locked tightly), so that the moving mechanism 23 can stay at the designated position.

[0029] The speaker body 1 is located in the protective housing 22, which means that the protective housing 22 can protect the speaker body 1 (including but not limited to the situation where it accidentally tipes over when this embodiment is moved), thereby improving the safety of the speaker body 1 and ensuring that the speaker body 1 works stably.

[0030] The protective housing 22 has a first opening 221 and a second opening 222 at its two ends, respectively. The first opening 221 and the second opening 222 correspond to the front and back of the speaker body 1, respectively, so that the staff can connect the power cord to the speaker body 1 and prevent the protective housing 22 from blocking the sound waves emitted by the speaker body 1.

[0031] like Figures 2-4 As shown, both the first opening 221 and the second opening 222 are provided with a baffle plate 3. Each baffle plate 3 is rotatably connected to the protective housing 22. That is, when the present embodiment is not in working state, the first opening 221 or the second opening 222 is covered or blocked by rotating the baffle plate 3 corresponding to the first opening 221 or the second opening 222, so that the protective housing 22 is in a closed state, ensuring the protective effect of the protective housing 22 on the speaker body 1.

[0032] The longitudinal section of the movable base 21 is a "U" shaped structure, with the speaker body 1 located on top of it. Specifically, the movable base 21 includes a receiving groove, in which the speaker body 1 is located. This allows the movable base 21 to constrain the speaker body 1, thereby preventing the speaker body 1 from being displaced under stress during use and falling off the movable mechanism 2 along the first opening 221 or the second opening 222, thus ensuring the overall structural stability of this embodiment.

[0033] The protective housing 22 is provided with an extended rotating part 223, which is integrally formed with the protective housing 22 to ensure the connection strength between the two. Each baffle plate 3 is rotatably connected to the extended rotating part 223. Each baffle plate 3 has an extended rotating part 223 on both sides, so that each baffle plate 3 has a rotation point and a support point at both ends, ensuring that each baffle plate 3 can rotate and flip stably. Moreover, the presence of each extended rotating part 223 allows each baffle plate 3 to rotate 270° around its rotation point with the extended rotating part 223.

[0034] Both the first opening 221 and the second opening 222 are provided with two baffles 3. Each baffle 3 is symmetrically and evenly distributed around the protective shell 22. That is, two adjacent baffles 3 can be flipped in a double-door manner to open the corresponding first opening 221 or second opening 222. Compared with opening the first opening 221 or second opening 222 in a single-door manner, the operating space requirement is smaller and it is more convenient for staff to operate this embodiment.

[0035] The protective housing 22 is provided with several gravity locks 4. Each gravity lock 4 mainly includes a lock base and a lock element. Each lock base is fixedly connected to the protective housing 22, and each lock element is slidably connected to the lock base. Each lock element is preferably an inverted "L" shaped structure, so as to prevent the lock element from detaching from the lock base under the influence of gravity. With the help of gravity, the lock element moves to the lowest point and abuts against each baffle 3, thereby fixing the baffle 3 by restricting the rotational movement of the baffle 3, so that this embodiment can maintain a stable structure.

[0036] The adjacent surfaces (end faces) of adjacent shielding plates 3 are all arc-shaped structures. In this way, when each shielding plate 3 is rotated 270° on the protective housing 22, it can avoid being completely attached to the protective housing 22. Moreover, there is a gap between each adjacent shielding plate 3 after rotation, so that the operator can reset the shielding plate 3 by inserting his / her finger into the gap between the arc-shaped structure and the protective housing 22 and then applying force (provided that the fixing effect of the gravity lock 4 on the shielding plate 3 is canceled), thus achieving the rapid reset of the shielding plate 3.

[0037] Meanwhile, the protective housing 22 is provided with several heat dissipation grooves to dissipate the heat generated by the speaker body 1 during operation. Furthermore, the presence of each heat dissipation groove allows the operator to access more surfaces of the shield 3 by inserting their fingers into the heat dissipation grooves during the reset process, making it easier for the operator to exert force and further improving the portability of resetting each shield 3.

[0038] The protective housing 22 is provided with a lifting structure 5, which includes several lifting handles 51. Each lifting handle 51 is preferably integrally formed with the protective housing 22 to ensure the connection strength between the two. This prevents the lifting handle 51 from breaking when the operator lifts the embodiment by pulling the lifting handle 51 to avoid steps or other obstacles, which could lead to the protective housing 22 and the speaker body 1 located therein tipping over and causing damage to the speaker body 1 or other uncontrollable losses. Preferably, each lifting handle 51 forms an "H" shape on the protective housing 22, allowing the operator to lift the embodiment with one hand or both hands, effectively improving the flexibility of use. When lifting with both hands, the force points are evenly distributed on both sides of the protective housing 22, and the symmetrical force points on both sides can balance the load, preventing the protective housing 22 from tilting or shaking due to uneven force on one side, thus reducing the risk of accidental fall.
