Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a mobile outdoor speaker structure, including an outer speaker compartment 1, an inner speaker compartment 2 is provided inside the outer speaker compartment 1, and an opening and closing mechanism 3 is also included;

[0023] Opening and closing mechanism 3: It includes a sealing plate 31, a sliding groove 32, a socket 37, and a limiting plate 38. The sliding groove 32 is symmetrically arranged on the upper and lower inner walls of the speaker outer chamber 1. The end of the sealing plate 31 away from the center of the speaker outer chamber 1 is fixedly connected to a sliding column. The outer surface of the sliding column is slidably connected to the interior of the vertically adjacent sliding groove 32. The front surface of the sealing plate 31 is provided with a rib groove at the end near the center of the speaker outer chamber 1. The upper end of the speaker outer chamber 1 is provided with a socket 37. The limiting plate 38 is inserted into the socket 37. The rib groove is installed in conjunction with the corresponding end of the limiting plate 38. The opening and closing mechanism 3 also includes a rotating shaft 33, a gear 34, a rack plate 35, and a rack plate 36. The rotating shaft 34... 3. The left and right ends of the rotating shaft 33 are respectively rotatably connected to the top wall of the speaker outer chamber 1. The lower end of each shaft 33 is fixedly connected to a gear 34. The first rack plate 35 is fixedly connected to the upper end of the left and right side surfaces of the speaker inner chamber 2. The first rack plate 35 is meshed with the horizontally adjacent gear 34. The second rack plate 36 is fixedly connected to the upper end of the rear surface of the sealing plate 31. The second rack plate 36 is installed in conjunction with the vertically adjacent gear 34. The bottom wall of the speaker outer chamber 1 is provided with symmetrically distributed guide grooves 16. The lower end of the speaker inner chamber 2 is fixedly connected with symmetrically distributed sliding blocks 17. The sliding blocks 17 are slidably connected with the vertically adjacent guide grooves 16. When the limiting plate 38 is pulled upward, when the limiting plate is in place... When plate 38 finishes insertion with the two vertically adjacent rib slots, the positions of the two sealing plates 31 are locked. Then, the sealing plates 31 are rotated outward. Each sealing plate 31 rotates around the central axis of the corresponding sliding column in a direction away from the center of the speaker outer chamber 1. When the sealing plate 31 is parallel to the side wall of the speaker outer chamber 1, the sealing plate 31 is pushed backward. The sliding columns slide backward inside the corresponding sliding grooves 32. The backward movement of the sealing plates 31 causes the corresponding rack plate 2 36 to move backward. When the rack plate 2 36 contacts the longitudinally adjacent gear 34, the gear 34 rotates, causing the transversely adjacent rack plate 1 35 to move forward, thereby causing the speaker outer chamber 2 to move forward. The sliding blocks 17 are all in the corresponding guide grooves 1. 6. The internal sliding mechanism provides sliding support and guide limit for the movement of the speaker outer chamber 2. When the sealing plate 31 is opened, the speaker outer chamber 2 is automatically released simultaneously. The upper end of the speaker outer chamber 1 is fixedly connected to a handle. The rear end of the lower surface of the speaker outer chamber 1 is rotatably connected to a moving shaft 14. Both ends of the moving shaft 14 are fixedly connected to moving wheels. The front end of the lower surface of the speaker outer chamber 1 is fixedly connected to a support foot 15. The speaker outer chamber 1 is moved by the handle, and the moving wheels follow the moving shaft 14 to rotate, assisting the movement of the speaker outer chamber 1. When the speaker outer chamber 1 reaches the desired position, the handle is stopped, and the support foot 15 and the two moving wheels provide stable three-point support for the speaker outer chamber 1.

[0024] The speaker enclosure 2 has the following components: a microcontroller 4 is installed on the upper part of the rear inner wall; a battery 7 is installed on the bottom wall of the speaker enclosure 2, with the output of the battery 7 electrically connected to the input of the microcontroller 4; a crossover 5 is installed in the middle of the rear inner wall of the speaker enclosure 2; a speaker 6 is installed at the lower end of the speaker enclosure 2, with a protective mesh 10 at the front of the speaker 6; the input of the crossover 5 is electrically connected to the output of the microcontroller 4, and the input of the speaker 6 is electrically connected to the output of the crossover 5; a display screen 8 is installed on the upper part of the front surface of the speaker enclosure 2; a mixing console 9 is installed on the upper part of the front surface of the speaker enclosure 2, with the input of the display screen 8 electrically connected to the output of the microcontroller 4; the mixing console 9 is bidirectionally electrically connected to the microcontroller 4; a through hole is provided at the rear end of the speaker enclosure 1; a power cord 11 is provided at the rear end of the speaker enclosure 2, with the output of the power cord 11 electrically connected to the input of the battery 7. The input end of the power cord 11 is electrically connected to an external power source via a plug 13. A fixing post 12 is fixedly connected to the rear end of the speaker enclosure 1. The middle part of the power cord 11 is wound around the outer surface of the fixing post 12. The mixing console 9 sends instructions to the microcontroller 4, which controls the crossover 5 to operate. The crossover 5 separates the input analog audio signal into different parts such as high, mid, and low frequencies, and then sends them to the corresponding high, mid, and low frequency units of the speaker 6, which then play the sound. Under the control of the mixing console 9, multiple input signals can be amplified, mixed, distributed, and processed for sound quality and audio effects. At the same time, the microcontroller 4 enables the display screen 8 to operate, which displays the music playback status. The input end of the power cord 11 can be electrically connected to an external power source via the plug 13. The power cord 11 supplies power to the battery 7, enabling the battery 7 to be charged.

[0025] The working principle of the portable outdoor speaker structure provided by this utility model is as follows: During operation, the operator first moves the speaker outer chamber 1 using the handle. The moving wheels follow the rotating shaft 14, assisting in the movement of the speaker outer chamber 1. When the speaker outer chamber 1 reaches the desired position, the operator stops pulling the handle. The support legs 15 and the two moving wheels provide stable three-point support for the speaker outer chamber 1. Then, the operator pulls the limiting plate 38 upwards. When the limiting plate 38 finishes engaging with the two vertically adjacent rib slots, the positions of the two sealing plates 31 are locked. The operator then rotates the sealing plates 31 outwards. The sealing plates 31 rotate around the central axis of the corresponding sliding column in a direction away from the center of the speaker outer chamber 1. When the sealing plates 31 are parallel to the side wall of the speaker outer chamber 1, the operator pushes the sealing plates 31 backwards. The sliding columns slide backwards within the corresponding sliding grooves 32. The backward movement of the sealing plates 31 causes the corresponding rack plate 36 to move backwards. When the rack plate 36 contacts the longitudinally adjacent gear 34, the gear 34 rotates, causing the transverse... The adjacent rack plate 35 moves forward, thereby causing the speaker outer chamber 2 to move forward. The sliding blocks 17 slide inside the corresponding guide grooves 16, providing sliding support and guiding limit for the movement of the speaker outer chamber 2. When the sealing plate 31 is opened, the speaker outer chamber 2 is automatically released simultaneously. Then, the operator issues a command to the microcontroller 4 through the mixing console 9. The microcontroller 4 controls the crossover 5 to operate. The crossover 5 separates the input analog audio signal into different parts such as high, mid, and low frequencies, and then sends them to the corresponding high, mid, and low frequency units of the speaker 6. The speaker 6 plays the sound. Under the control of the mixing console 9, multiple input signals can be amplified, mixed, distributed, and have their sound quality modified and sound effects processed. At the same time, the microcontroller 4 enables the display screen 8 to operate. The display screen 8 displays the music playback status. The operator can connect the input end of the power cord 11 to an external power source through the plug 13. The power cord 11 supplies power to the battery 7, enabling the battery 7 to be charged.

[0026] It is worth noting that the crossover 5 disclosed in the above embodiments can be an A1419 crossover, the mixing console 9 can be a DT8 professional 8-channel mixing console, and the microcontroller 4 controls the operation of the crossover 5, speaker 6, battery 7, display screen 8 and mixing console 9 using methods commonly used in the prior art.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
