Description

Technical Field

[0001] The invention relates to the field of portable audio, and in particular to a portable multifunctional lighting audio. Background Art

[0002] As people's demand for portable electronic devices increases, multifunctional lighting and audio have gradually become important tools for outdoor activities, home entertainment and commercial displays. Traditional portable audio usually has a single function and only focuses on sound output. In actual use, users often need to take into account multiple needs such as lighting, portability and stability. In addition, when used outdoors, traditional audio is prone to tipping over due to uneven ground or external force, affecting the use effect. In order to solve these problems, some improvement solutions have been proposed in the prior art, such as adding counterweights to enhance stability, or designing detachable sound amplification covers to improve sound effects. However, these solutions are often complex in structure, inconvenient to operate, and difficult to take into account multiple functions.

[0003] Therefore now develop a kind of portable multifunctional lighting sound system for the problems mentioned above. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the technical problem is: to provide a portable and multifunctional light and sound system.

[0005] The technical solution of the present invention is: a portable multifunctional light and sound system, comprising a first installation frame, a second installation frame is arranged at the rear side of the first installation frame, a speaker is installed at the front side of the first installation frame, two left-right symmetrical lights are arranged at the front side of the upper part of the first installation frame, a first limiting member is arranged between the lower parts of the first installation frame and the second installation frame, a plurality of weighted balls are placed in the first limiting member, a second limiting member is slidably arranged on the first limiting member, a pull ring is arranged at the bottom of the second limiting member, limiting blocks are slidably arranged on both sides of the left and right sides of the second limiting member, the limiting blocks are clamped with the first limiting member, and the A connecting rod is rotatably connected between the limit block and the second limit piece, and there are four connecting rods in total. A first spring is connected between the limit block and the second limit piece, and a second spring is connected between the limit block and the first limit piece. By pulling the pull ring downward, the connecting rod drives the limit blocks to slide inward, so that the first springs are compressed. At the same time, the pull ring drives the second limit piece to move downward, and the second springs are compressed. At this time, the first limit piece and the second limit piece no longer limit the counterweight ball, and the counterweight ball can move freely, thereby stabilizing the overall center of gravity of the speaker.

[0006] Optionally, it further includes a sound amplifying cover. The sound amplifying cover is installed on the front side of the first mounting frame. A first auxiliary plate is installed on the sound amplifying cover, which is used to assist in the installation of the sound amplifying cover. A first magnetic attraction block is connected to the rear side of the sound amplifying cover, and a second magnetic attraction block is connected to the front side of the first mounting frame. A second magnetic attraction block is also installed in the second mounting frame.

[0007] Optionally, it further includes a handle. The handle is rotatably arranged on the rear side of the second mounting frame. There are two torsion springs between the handle and the second mounting frame. Anti-slip blocks are arranged on the handle.

[0008] Optionally, it further includes a dust-proof net. The dust-proof net is arranged on the front side of the first mounting frame. A third magnetic attraction block is installed on the dust-proof net. Two second auxiliary plates are installed on the front side of the dust-proof net.

[0009] Optionally, it further includes a dust-proof plate. The dust-proof plate is rotatably installed on the upper side of the first mounting frame. A clamping member is arranged on the dust-proof plate, which is used to install and fix the dust-proof plate.

[0010] Optionally, a carrying handle is arranged between the first mounting frame and the second mounting frame.

[0011] Optionally, the outer sides of the limiting blocks are all inclined surface structures.

[0012] Optionally, it further includes an auxiliary grip structure. The auxiliary grip structure is arranged on the carrying handle.

[0013] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: 1. Through the collaborative design of the counterweight ball and the limiting structure, the present invention realizes the dynamic center of gravity adjustment function. When the sound box is tilted or moved, the user only needs to pull the pull ring, and the counterweight ball can roll freely to automatically adjust the center of gravity position, ensuring that the sound box remains stable in different usage scenarios. This not only improves the anti-tipping ability of the sound box but also enhances its applicability on outdoor or uneven ground, providing a safer and more reliable usage experience for users.

[0014] 2. The present invention adopts a modular design. Components such as the sound amplifying cover, dust-proof net, and dust-proof plate can be quickly installed and disassembled. The sound amplifying cover is fixed by magnetic attraction blocks, which is convenient for users to enhance the sound effect or protect the speaker according to their needs. The dust-proof net and dust-proof plate effectively prevent dust from entering and extend the service life of the sound box. In addition, the combined design of the handle and the carrying handle is convenient for carrying and can also be used as a support foot to adjust the angle of the sound box, meeting the diverse needs of users in different scenarios.

Detailed implementation manners

[0025] The following describes the implementation manners of the present invention with reference to the drawings.

[0026] Embodiment 1 A portable multi-functional light and sound, such as Figures 1-9As shown in the figure, it includes a first mounting frame 1. A second mounting frame 2 is provided at the rear side of the first mounting frame 1. A speaker 3 is installed at the front side of the first mounting frame 1. Two symmetrically arranged lights 4 are provided at the front side of the upper part of the first mounting frame 1. A handle 5 is provided between the first mounting frame 1 and the second mounting frame 2. An auxiliary grip structure 26 is provided on the handle 5. A first limiting member 6 is provided between the lower parts of the first mounting frame 1 and the second mounting frame 2. A plurality of counterweight balls 7 are placed in the first limiting member 6. A second limiting member 8 is slidably arranged on the first limiting member 6. A pull ring 9 is provided at the bottom of the second limiting member 8. Limiting blocks 11 are slidably arranged on both the left and right sides of the second limiting member 8. The outer sides of the limiting blocks 11 are both inclined surface structures. The limiting blocks 11 are clamped with the first limiting member 6. Link rods 10 are rotatably connected between the limiting blocks 11 and the second limiting member 8. There are four link rods 10 in total. First springs 12 are connected between the limiting blocks 11 and the second limiting member 8. Second springs 13 are connected between the limiting blocks 11 and the first limiting member 6. By pulling down the pull ring 9, the link rods 10 drive the limiting blocks 11 to slide inwards, causing the first springs 12 to be compressed. At the same time, the pull ring 9 drives the second limiting member 8 to move downwards, causing the second springs 13 to be compressed. At this time, the first limiting member 6 and the second limiting member 8 no longer limit the counterweight balls 7, and the counterweight balls 7 can move freely, thus making the overall center of gravity of the speaker stable.

[0027] It should be noted that when not in operation, the first limiting member 6 and the second limiting member 8 are clamped with the first limiting member 6 through the inclined plane structure of the limiting block 11, and the counterweight ball 7 is restricted within the first limiting member 6 and cannot move freely. At this time, the overall center of gravity of the speaker is fixed and remains in a stable state. When the user pulls down the pull ring 9, the pull ring 9 drives the second limiting member 8 to move downward. Since the second limiting member 8 and the limiting block 11 are connected by a connecting rod 10 and the connecting rod 10 is rotatably connected, pulling down the pull ring 9 will drive the limiting block 11 to slide inward through the connecting rod 10. When the limiting block 11 slides inward, the first spring 12 (connecting the limiting block 11 and the second limiting member 8) is compressed, and at the same time, the second spring 13 between the limiting block 11 and the first limiting member 6 is also compressed. Since the outer side of the limiting block 11 is an inclined plane structure, its inward sliding will gradually disengage from the clamping state with the first limiting member 6. When the limiting block 11 completely disengages from the clamping of the first limiting member 6, the first limiting member 6 and the second limiting member 8 no longer limit the counterweight ball 7, and the counterweight ball 7 can roll freely within the first limiting member 6. After the counterweight ball 7 rolls freely, it will automatically adjust its position according to the tilting or moving state of the speaker. For example, when the speaker tilts to one side, the counterweight ball 7 will roll to the lower side, thereby changing the center of gravity distribution of the speaker and restoring it to a balanced state. When reset is required, continue to pull down the pull ring 9 so that the limiting block 11 disengages from the clamping again. At this time, the second limiting member 8 is reset upward under the elastic force of the first spring 12 and the second spring 13, and at the same time, the connecting rod 10 drives the limiting block 11 to slide outward and reconnect with the first limiting member 6, and the counterweight ball 7 is restricted within the first limiting member 6 again, and the center of gravity of the speaker returns to the fixed state.

[0028] It further includes a sound amplification cover 14. The sound amplification cover 14 is installed on the front side of the first mounting frame 1. A first auxiliary plate 15 is installed on the sound amplification cover 14, and the first auxiliary plate 15 is used to assist in the installation of the sound amplification cover 14. A first magnetic attraction block 16 is connected to the rear side of the sound amplification cover 14, and a second magnetic attraction block 17 is connected to the front side of the first mounting frame 1. The second magnetic attraction block 17 is also installed in the second mounting frame 2.

[0029] It should be noted that the sound amplification cover 14 is installed on the front side of the first installation frame 1 and is used to enhance the acoustic effect of the speaker. A first auxiliary plate 15 is installed on the sound amplification cover 14. The function of the first auxiliary plate 15 is to assist in the installation of the sound amplification cover 14 to ensure that it can be accurately and stably fixed on the first installation frame 1. A first magnetic attraction block 16 is connected to the rear side of the sound amplification cover 14, and second magnetic attraction blocks 17 are installed on both the front side of the first installation frame 1 and inside the second installation frame 2. Through the magnetic attraction between the first magnetic attraction block 16 and the second magnetic attraction blocks 17, the sound amplification cover 14 can be quickly and firmly adsorbed on the first installation frame 1, and at the same time, it is convenient for users to disassemble and replace. When the sound amplification cover 14 approaches the first installation frame 1, the first magnetic attraction block 16 on the rear side of the sound amplification cover 14 will automatically adsorb to the second magnetic attraction block 17 on the front side of the first installation frame 1 to achieve the quick installation of the sound amplification cover 14. If disassembly is required, the sound amplification cover 14 is placed inside the second installation frame 2, and the second magnetic attraction blocks 17 inside the second installation frame 2 can also form additional adsorption points with the first magnetic attraction block 16 on the rear side of the sound amplification cover 14 to enhance the placement stability of the sound amplification cover 14.

[0030] Embodiment 2 Based on Embodiment 1, it further includes a handle 18. The handle 18 is rotatably arranged at the rear side of the second installation frame 2. Two torsion springs 19 are arranged between the handle 18 and the second installation frame 2, and an anti-slip block 20 is arranged on the handle 18.

[0031] It should be noted that the handle 18 is rotatably arranged at the rear side of the second installation frame 2 and is connected to the second installation frame 2 by two torsion springs 19. The function of the torsion springs 19 is to provide elastic support for the handle 18 so that it can automatically return to the initial position after rotation. When the user needs to carry or adjust the speaker, the handle 18 can be pulled outwards. The handle 18 maintains a certain tension under the action of the torsion springs 19, which is convenient for operation. The anti-slip block 20 is arranged on the handle 18 and is made of anti-slip material, which can increase the friction when the user holds it and prevent the speaker from slipping during carrying. After the user holds the handle 18, the speaker can be easily lifted to achieve portable movement. Since the handle 18 is connected to the second installation frame 2 through the torsion springs 19, its rotation range is flexible and can adapt to the holding habits of different users. When the speaker needs to be placed on the ground or other planes, the user can rotate the handle 18 outwards to a certain angle so that it can be used as a support foot. The rotation angle of the handle 18 can be adjusted by the elasticity of the torsion springs 19 to ensure that the speaker can be stably placed. The design of the anti-slip block 20 can also increase the friction between the handle 18 and the contact surface to prevent the speaker from sliding or tipping over.

[0032] It further includes a dust-proof net 21. The dust-proof net 21 is arranged on the front side of the first installation frame 1. A third magnetic attraction block 22 is installed on the dust-proof net 21, and two second auxiliary plates 23 are installed on the front side of the dust-proof net 21.

[0033] It should be noted that when the dust-proof net 21 needs to be installed, the second auxiliary plate 23 is relied on to hold the dust-proof net 21, and the quick installation can be completed through the adsorption connection between the third magnetic block 22 and the second magnetic block 17. It should be noted that the sound amplifying cover 14 and the dust-proof net 21 cannot be installed simultaneously, and the installation combination can be flexibly adjusted according to needs.

[0034] It further includes a dust-proof plate 24. The dust-proof plate 24 is rotatably installed on the upper side of the first installation frame 1. A clamping member 25 is provided on the dust-proof plate 24, and the clamping member 25 is used for installing and fixing the dust-proof plate 24.
