Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a bird's nest type multi-purpose combined audio system. Background Art

[0002] Speakers are devices that use electronic circuits to convert audio and electronic signals, reproducing and playing audio signals. There are many types of speakers, and line array speakers are composed of multiple linear array speakers, visually resembling a bird's nest. Having multiple speakers with the same amplitude and phase can make the sound transmission louder.

[0003] The existing patent document with the announcement number CN209120457U discloses a bird's nest-shaped multi-purpose speaker and a combination speaker, which is composed of a plurality of speakers and an arc-shaped connecting frame. The arc-shaped connecting frame connects the plurality of speakers through a connecting structure, so that the sound-displaying boards of the plurality of speakers are in an arc-shaped diffusion shape. In this device, the arc-shaped connecting frame connects the plurality of speakers through the connecting structure. Because the left and right panels of the speaker box have a certain inclination angle, the arc-shaped connecting frame makes the left and right panels of adjacent speakers abut and fit together when the plurality of speakers are connected, so that the sound-displaying boards of the plurality of speakers are in an arc-shaped diffusion shape. The sound waves of the combination audio system are dispersed, thereby making the sound wave radiation surface of the combination audio system fan-shaped, thereby increasing the sound wave coverage area of ​​the combination audio system, and can increase the number of audiences and the audience's sound experience in places with larger venues. However, it also has disadvantages. Each box in the device must be individually fixed and connected by screws. Because there are sixteen boxes in the design, the overall disassembly and assembly workload is large and the task is heavy. Moreover, when the audio system is working, the vibration and friction between each other will further cause the screws to loosen, which is not conducive to the fixation effect. The adjacent boxes will also be damaged due to mutual friction, and the overall use is inconvenient.

[0004] Therefore, in view of the fact that each box in the above-mentioned reference patent is fixed with screws, the overall disassembly and assembly workload is large and the task is heavy. Moreover, when the audio is working, the vibration will cause the adjacent boxes to rub against each other and cause damage. The screws are easy to loosen, which is not conducive to the fixing effect. It is inconvenient to use as a whole. A bird's nest-type multi-purpose combination audio system can be designed. After placing eighteen boxes at corresponding positions on the chassis, the cylinder is started to push the lifting ring to drive the connecting plate downward. The connecting plate pushes each block into the slot on the box, thereby quickly completing the fixation. It is convenient to disassemble and assemble, with less workload and high work efficiency. The boxes are separated by partitions to avoid damage caused by vibration caused by friction between the boxes. Utility Model Content

The overall workload is small and the disassembly and assembly efficiency is high. When the audio is enabled, the boxes 4 are separated by the partition plates 3 to avoid vibration and friction between the adjacent boxes 4 and damage, thereby extending the service life of the boxes 4.

[0024] See also Figure 1 and Figure 5 In this embodiment, a lifting plate 11 is provided on the inner side of the lifting ring 7, and a curtain 12 is fixedly connected to the outer side of the bottom of the lifting plate 11. After the lifting plate 11 rises, the bottom curtain 12 is expanded outward, and then the lifting plate 11 is lowered, so that the curtain 12 covers the outer side of each box body 4, which has a good dust-proof effect and prevents dust from accumulating in the holes and grooves on the box body 4. A metal ring 21 is fixedly connected to the outer side of the chassis 1, and eighteen magnetic blocks 22 are fixedly connected to the inner lower end of the curtain 12 in a circular array. After the curtain 12 is covered on the box body 4, the magnetic block 22 at the bottom can be adsorbed on the metal ring 21 on the outer side of the chassis 1, thereby fixing the curtain 12 to prevent it from being blown up by the wind and affecting the covering. Four universal wheels 23 are symmetrically fixedly connected to the bottom of the chassis 1, and the universal wheels 23 facilitate the movement of the pushing device.

[0025] See also Figure 2 and Figure 5In this embodiment, a lifting column 13 is fixedly connected to the bottom center of the lifting plate 11, and fixed plates 14 are symmetrically fixedly connected to the left and right ends of the bottom outer side of the lifting column 13.

A motor 17 is fixedly connected to the upper end of the U-shaped support seat 15. The output shaft of the motor 17 is fixedly connected to the threaded rod 16. When the motor 17 is started, the threaded rod 16 is driven to rotate. The threaded rod 16 drives the fixed plate 14 on the left to perform lifting movements, thereby controlling the lifting movement of the lifting column 13. A U-shaped support seat 2 18 is fixedly connected to the upper end of the chassis 1 and located on the right side of the center.

A guide block 20 is fixedly connected between the upper ends of the U-shaped support seat 15 and the U-shaped support seat 2 18, and the lifting column 13 is movably arranged to pass through the guide block 20. When the lifting column 13 moves up and down, the fixed plate 14 on the right slides on the outside of the guide rod 19, and the lifting column 13 itself slides on the outside of the guide block 20, maintaining its lifting stability.

[0026] When working, the eighteen boxes 4 are placed on the chassis 1 and placed between the two adjacent partition plates 3, with the rear side abutting the outer side of the fixing ring 2, and then the four cylinders 6 are started at the same time to push the lifting ring 7 to move downward, and the lifting ring 7 drives the eighteen connecting plates 8 to move downward, and the connecting plates 8 push each card block 9 downward to be inserted into the card slot 10 on the box body 4, and the disassembly and fixing are completed quickly. Each box body 4 is separated by the partition plate 3 to avoid vibration causing damage to the adjacent box bodies 4 due to friction. When the equipment is not in use, the motor 17 is started to drive the threaded rod 16 to rotate, and cooperate with the guide rod 19 and the guide block 20, the left and right fixed plates 14 drive the lifting column 13 to rise, and push the lifting plate 11 to a certain height, and then the curtain 12 at the bottom of the lifting plate 11 is dragged outward and covered on the outer side of the eighteen boxes 4, and the curtain 12 is fixed to the metal ring 21 on the outer side of the chassis 1 through the eighteen magnetic blocks 22 at the bottom, thereby having a good dustproof and isolation effect on the box body 4.

[0027] Through the above steps, after the eighteen boxes 4 are placed in the corresponding positions on the chassis 1, the four cylinders 6 are started at the same time to push the lifting ring 7 to move downward, and the lifting ring 7 drives the eighteen connecting plates 8 to move downward. The connecting plates 8 push each card block 9 downward and insert it into the card slot 10 on the box 4, so as to quickly complete the fixation and facilitate disassembly and assembly. The overall workload is small and the disassembly and assembly efficiency is high. When the audio is activated, the boxes 4 are separated by partition plates 3 to avoid vibration causing friction and damage to adjacent boxes 4, thereby extending the service life of the box 4, so as to solve the problem that each box 4 in the reference patent is fixed with screws, resulting in a large workload for disassembly and assembly of the box 4, and a heavy workload. Moreover, when the audio is working, vibration will cause adjacent boxes to rub against each other and cause damage, and the screws are easy to loosen, which is not conducive to the fixation effect, and the overall problem of inconvenience in use.
