Abstract

The invention relates to an active noise reduction device applied to a multilayered glass window and belongs to the technical field of noise control. The active noise reduction device comprises a shell, an electromagnet, an acceleration transducer, a processor and a permanent magnet; the shell is a barrel-shaped shell body with a sealed bottom surface; the shell is adsorbed on the inner surface ofinner-layer glass of the multilayered glass window through an adsorption device; the electromagnet is fixedly arranged in the shell and one end face of the electromagnet is clung to the inner surfaceof the inner-layer glass; the other end face of the electromagnet is fixedly connected with the acceleration transducer; the processor is arranged in the shell and is electrically connected with theelectromagnet and the acceleration transducer respectively; the permanent magnet is of a sheet-shaped structure; the permanent magnet is arranged on the outer surface of outer-layer glass of the multilayered glass window, is arranged relative to the electromagnet in a window body and is adsorbed and fixed through a magnetic force of the electromagnet.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to an active noise reduction device applied to multiple glass windows. Background technique [0002] With the progress of modern society and the improvement of people's living standards, the problem of noise pollution has become increasingly prominent, which has seriously affected people's daily life and health. For the daily home environment, the problem of noise pollution is mainly reflected in several aspects such as industrial noise, construction noise, traffic noise, and social noise, and windows are the main transmission channel for the above-mentioned noise to enter the room. Therefore, the sound insulation performance of windows is highly valued by people. At present, windows with higher sound insulation generally adopt a two-layer or even three-layer glass structure, which has a larger sound insulation at medium and high frequencies. But in the low-frequency band, t...
