Sound insulation window based on magnetic buffer ventilation

Abstract

The invention discloses a sound insulation window based on magnetic buffer ventilation, and belongs to the technical field of sound insulation. According to the sound insulation window based on magnetic buffer ventilation, in the scheme, a rolling cloth is pulled out from a winding device by rightwards pulling a traction column, and the traction column is clamped on a T-shaped locking rod at any position; through the mutual repulsion effect between magnetic strips and annular magnet blocks, movable liquid bags are driven to move rightwards until making contact with dislocation cushion blocks,so that noise passes through gaps between the movable liquid bags and the dislocation cushion blocks, and is absorbed; and under the mutual attraction effect of the movable liquid bags and magnet sheets, capillary fiber thorns adsorbed on the outer sides of outer rubber layers stand, thus the noise is absorbed, the capillary fiber thorns are arranged to be similar to barbs on the animal tongue, the dust is filtered accordingly, and with accumulation of the dust, built-in sound storage grooves can be filled to simulate multi-void structures, so that the sound insulation effect is further improved.

Description

technical field [0001] The invention relates to the technical field of sound insulation, and more specifically relates to a sound insulation window based on magnetic buffering and ventilation. Background technique [0002] Sound insulation refers to the isolation, isolation, separation, etc. of sound or noise through certain objects, so sound insulation materials are needed. The decibel number related to the incident sound energy on one side of the material and the transmitted sound energy on the other side is the insulation volume of the material, usually expressed by the symbol R (dB). A type of material, component or structure, characterized by heavy mass and high density, such as steel plate, lead plate, concrete wall, brick wall, etc., which are generally used in office places or KTV. [0003] Sound insulation materials or components will have different sound insulation effects due to different use occasions and different test methods. For sound insulation materials, t...

Problems solved by technology

[0004] In the prior art, soundproof glass has been applied to aluminum alloy windows, but when the aluminum alloy windows are closed for sound insulation, the windows will not be able to breathe freely. During a long rest, the indoor carbon dioxide concentration and PM2.5 content will also increase, which is harmful to people. There is a certain threat to health, so it is necessary to open the window to maintain indoor air circulation, so there is a contradiction in use
