Problems solved by technology

This kind of flat sound-absorbing ceiling or sound-absorbing wall cannot target any sound source, and can only have a strong sound-absorbing effect on the sound that propagates perpendicular to the wall or ceiling, so the sound-absorbing effect is greatly reduced

Embodiment

[0028] see figure 1 and figure 2 , this embodiment discloses a sound-absorbing ceiling, which includes a plurality of freely arranged pyramidal sound-absorbing units 1 and edge sound-absorbing units 2; The board 3 is composed of pyramids, the surface of the sound-absorbing board 3 is covered with baking varnish; the edge sound-absorbing unit 2 is a sound-absorbing board 3 whose shape matches the pyramid sound-absorbing unit 1, the surface of the sound-absorbing board 3 is covered with baking varnish, and the edge sound-absorbing unit 2 is arranged on The edge of the ceiling.

[0029] The biggest difference between the sound-absorbing ceiling of the present invention and the prior art is that the ceiling surface is changed from a plane to a plurality of pyramidal sound-absorbing units 1 . A plurality of pyramidal sound-absorbing units 1 form a composite sound-absorbing ceiling composed of multiple conical surfaces. The sound-absorbing panels 3 of the pyramidal sound-absorbin...

Abstract

The invention provides a sound-absorbing ceiling which comprises a plurality of pyramid sound-absorbing units and edge sound-absorbing units, wherein the pyramid sound-absorbing units are freely distributed; the pyramid sound-absorbing units are vertically and horizontally distributed in the middle of the sound-absorbing ceiling; the pyramid sound-absorbing units are formed by at least three sound-absorbing plates arranged in a pyramid form; baking varnishes are coated on the surfaces of the sound-absorbing plates; the edge sound-absorbing units are arranged as the sound-absorbing plates having the shape matched with the shape of the pyramid sound-absorbing units; the baking varnishes are coated on the surfaces of the sound-absorbing plates; the edge sound-absorbing units are distributed at the edges of the ceiling. The sound-absorbing ceiling can absorb the sound propagating along different directions and the sound-absorbing effect is greatly promoted.

Description

technical field [0001] The invention relates to the field of decorative building materials, in particular to a sound-absorbing ceiling. Background technique [0002] Ceiling is a common product in construction, and its main function is interior decoration, making the interior of the building more beautiful. For some noisy environments, the walls and ceilings inside the building also have sound-absorbing requirements. [0003] Common sound-absorbing walls or ceilings are flat designs and covered with sound-absorbing materials for sound absorption. The sound-absorbing effect of this product depends entirely on the sound-absorbing material itself. Moreover, for the indoor environment, the location of the sound source is uncertain, which means that the noise will be emitted from any point in the room to the surroundings, resulting in sound waves emitted in different directions. This kind of planar sound-absorbing ceiling or sound-absorbing wall cannot target any sound source,...
