Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to an annular ceiling sound amplification device. Background Art

[0002] Ceiling sound reinforcement refers to the process of designing and arranging a ceiling structure to improve sound transmission. Typically, ceilings are a crucial component of interior decoration. By installing sound-absorbing panels on the ceiling to reduce sound reflection and echo, improving sound clarity and comfort, it effectively improves the transmission and quality of indoor sound, thereby achieving the purpose of sound reinforcement.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a ring-shaped ceiling sound reinforcement device, comprising a base plate 1, a mounting ring 2 fixed to the surface of the base plate 1, and a sound-absorbing panel 3 arranged inside the mounting ring 2. The sound-absorbing panel 3 is disc-shaped and made of polyester fiber, which is a common sound-absorbing material usually used to manufacture the sound-absorbing panel 3; it has good sound-absorbing performance, can effectively absorb sound waves, and has relatively low cost; a circle of first sound-absorbing cotton 4 in an annular state is fixedly connected to the circumferential side wall of the sound-absorbing panel 3, which is used to compensate for the gap between the sound-absorbing panel 3 and the mounting ring 2, and base blocks 12 are fixedly connected on both sides of the mounting ring 2. A slide groove 1201 is opened on the surface of the base block 12, and the slide groove 1201 is a T-shaped structure. A slider 6 is slidably connected inside the slide groove 1201, and a pressure strip 7 for limiting the position is fixedly connected to the end of the slider 6.

[0024] A sound-absorbing panel 3 is provided on the base plate 1 to reduce sound reflection and echo, improve the clarity of indoor sound, and thus achieve the purpose of sound amplification. The first sound-absorbing cotton 4 is used to compensate for the gap between the sound-absorbing panel 3 and the mounting ring 2, so as to ensure that sound does not escape through these gaps, thereby improving the sound absorption effect and further improving the acoustic environment of the room.

Compared with the existing bonding method, this method can flexibly fine-tune the rotation angle of the sound-absorbing panel 3 and has a wider applicability.

[0028] A bolt 11 is threadedly inserted into the pressure strip 7 for further tightening the sound absorbing panel 3 . By rotating the bolt 11 , the threaded end of the bolt 11 abuts against the surface of the sound absorbing panel 3 , thereby achieving the purpose of locking.
