Description

Technical Field

[0001] This utility model relates to the field of audio technology, and in particular to a combination audio system. Background Technology

[0002] Modular sound systems are high-fidelity audio systems with modular design at their core. They achieve sound quality optimization and scene adaptation through the flexible combination of independent functional components. Their advantages lie in the fact that the split structure reduces signal interference, supports the upgrade of individual modules as needed to improve performance, and is compatible with multi-channel expansion and digital ecosystem functions, making them suitable for performance scenarios of various sizes.

[0003] Existing modular audio systems often use customized brackets or bolts for fixing, resulting in low efficiency of physical connections between devices and difficulty in rapid assembly and disassembly. At the same time, the fixed installation structure makes it impossible to achieve precise angle adjustments, which limits the sound field coverage. Especially in complex acoustic environments, it is difficult to solve acoustic defects such as sound interference and comb filtering through angle optimization. Therefore, this paper proposes a modular audio system to overcome the above-mentioned defects. Utility Model Content

[0007] As a further description of the above technical solution: the rotating shaft has a circular groove inside, and the diameter of the circular groove matches the diameter of the threaded rod. The top of the outer side of the threaded rod has a retaining groove, and the vertical length of the retaining groove matches the vertical length of the ratchet, so that the ratchet can lock the rotation of the threaded rod and prevent the threaded rod from loosening at an angle.

[0008] As a further description of the above technical solution: a slide bar is provided on the outside of the linkage column, and a positioning groove is provided inside the rotating shaft. The shape and size of the positioning groove cross-section match the shape and size of the slide bar cross-section, so that the linkage column can move inside the rotating shaft under the push of the threaded rod.

[0009] As a further description of the above technical solution: the front end of the stop block is provided with a protrusion, and the vertical length of the protrusion matches the vertical length of the ratchet, so that the protrusion of the stop block can move inside the housing and fit with the ratchet, thereby locking the rotation angle of the ratchet.

[0010] As a further description of the above technical solution: the left end of the second quick-connect module is fixedly provided with a slot, and the shape and size of the slot cross-section are matched with the shape and size of the card block cross-section. The upper end of the card block is provided with a groove, and the shape and size of the groove cross-section are matched with the shape and size of the buckle cross-section, so that the card block is engaged with the buckle through the second quick-connect module.

[0011] As a further description of the above technical solution: the upper and lower ends of the movable card plate are provided with through holes, and the diameter of the through holes matches the diameter of the release lever, so that the buckle and the card block can be disengaged by pulling the release lever.

It also allows users to quickly adjust the speaker layout according to the site's shape and acoustic requirements. Whether it's a planar array or a stereo surround configuration, the sound coverage and uniformity can be optimized through fine-tuning of the angle. Furthermore, it simplifies the installation process, reducing labor and time costs. The adjustable angle feature effectively reduces sound interference and reflection interference, improving sound quality. It is suitable for diverse scenarios ranging from small and medium-sized events to large-scale performances. Additionally, the connecting parts can be folded for storage when the speakers are placed, saving space and reducing the risk of damage to the connectors. Attached Figure Description

A release lever 17 is welded inside the buckle 15.

[0026] As a further implementation of the above technical solution: the lower end of the knob 5 is attached to the upper end of the rotating shaft 2, the outer side of the stop block 11 is attached to the outer side of the ratchet 10, the end of the return spring 16 away from the stop block 11 is fixedly connected to the inside of the housing 1, and the outer side of the release lever 17 is slidably connected to the inside of the moving plate 13, so that by rotating the knob 5, the brake ring 7 is braked and rubbed against the inside of the housing 1, and then the ratchet 10 is used to lock the angle between the first quick-connect module 8 and the second quick-connect module 12.

[0027] As a further implementation of the above technical solution: a circular groove is provided inside the rotating shaft 2, and the diameter of the circular groove matches the diameter of the threaded rod 3. A slot is provided on the top of the outer side of the threaded rod 3, and the vertical length of the slot matches the vertical length of the ratchet 10, so that the ratchet 10 can lock the rotation of the threaded rod 3 and prevent the threaded rod 3 from loosening at an angle.

[0028] As a further implementation of the above technical solution: a slide bar is provided on the outside of the linkage column 6, and a positioning groove is provided inside the rotating shaft 2. The shape and size of the positioning groove cross-section match the shape and size of the slide bar cross-section, so that the linkage column 6 can move inside the rotating shaft 2 under the push of the threaded rod 3.

[0032] Working principle:

[0033] When using this utility model, rotate the rotating shaft 2 at the upper end of the housing 1. The rotating shaft 2 drives the first quick-connect module 8 and the second quick-connect module 12 to adjust their angles. When the angle is adjusted to a suitable angle, the user can hold the fixed rotating shaft 2 and rotate the knob 5. The knob 5 drives the threaded rod 3 at the lower end to rotate. The fixing ring 4 keeps the threaded rod 3 rotating in the rotating shaft 2. The threaded rod 3 drives the linkage column 6 to move, causing the linkage column 6 to move downward inside the rotating shaft 2. This causes the brake ring 7 at the lower end of the linkage column 6 to rub against the damping structure inside the housing 1 for braking. At the same time, the stop block 11 locks the rotation angle of the ratchet 10 to prevent the rotating shaft 2 from loosening. Then, the two chassis are connected. A quick-connect module 8 is connected to a second quick-connect module 12. The locking block 9 at the right end of the first quick-connect module 8 compresses the latch 15 inside the second quick-connect module 12, and causes the latch 15 to move upward and compress the first spring 14 with the moving plate 13, so that the locking block 9 and the latch 15 are engaged, completing the assembly of the speaker. By releasing the pull rod 17, the latch 15 is moved upward, releasing the connection between the latch 15 and the locking block 9, allowing the speakers to be separated. Then, the stop block 11 is pulled and the return spring 16 is compressed, so that the stop block 11 is disconnected from the ratchet 10, and the inner sides of the first quick-connect module 8 and the second quick-connect module are attached to the left and right ends of the housing 1, saving space for speaker placement.
