Novel sound absorber structure

Abstract

The invention relates to a novel sound absorber structure which is characterized in that a cuboid structure is adopted; two rectangular hanging bars are disposed in the cuboid structure; longer edges of the rectangular hanging bars coincide with diagonal lines of upper and lower bottom faces of the cuboid structure respectively; and intersection points of the diagonal lines of the upper and lower bottom faces of the cuboid structure are a hanging force bearing point and a solidification force bearing point of the two rectangular hanging bars respectively. Because of structural integrality of the structure provided by the invention, collapse and deformation of materials caused by changes of temperature and humidity are avoided; sound absorption performance of sound absorption materials is kept stable; appearance and shape are kept unchanged; and effects are good.

Description

technical field [0001] The invention relates to a space sound absorbing body, in particular to a novel sound absorbing body structure. Background technique [0002] Space sound absorbers are usually high-efficiency sound-absorbing products installed on the top of halls or gymnasiums. Because all of its six interfaces are exposed to the space sound field, the sound absorption efficiency is high, and the edge effect of the material makes it have a large sound absorption coefficient. In order to increase, it has a wide range of applications in the field of architectural acoustics. Space sound-absorbing body products made by traditional crafts generally have the disadvantages of large volume and heavy weight, which lead to poor decorative effect, complicated installation process, high cost, etc.: 1) High self-weight of space sound-absorbing body , Complicated installation - Due to the need for metal frames and metal meshes to be fixed, the space sound absorbing body products ma...

AI Technical Summary

Problems solved by technology

Space sound-absorbing body products made by traditional crafts generally have the disadvantages of large volume and heavy weight, which lead to poor decorative effect, complicated installation process, high cost, etc.: 1) High self-weight of space sound-absorbing body , Complicated installation - Due to the need for metal frames and metal meshes to be fixed, the space sound absorbing body products made by traditional crafts generally have the disadvantages of large volume and heavy weight, so their cost is high, the installation process is complicated, and the project cost is high; 2) The metal frame material and metal mesh surface of the space sound absorber have sound reflection, which will seriously affect the comprehensive sound absorption function of the sound absorber and reduce the sound absorption efficiency of the space sound absorber; 3) The decorative effect is poor

It hangs abruptly on the top of the building and cannot be evenly distributed. Usually, it can only guarantee functionality and cannot take into account the overall aesthetics; The frame is prone to deformation due to reasons such as shrinkage and uneven load-bearing

In addition, the weather resistance of the sound-absorbing material itself is poor, and factors such as prolonged exposure to the air or moisture will cause it to collapse, deform, etc., affecting its sound-absorbing effect
