Problems solved by technology

Noise can not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work; with the development of urbanization, the noise pollution generated by various automobile industries and electrical equipment is also increasing. Seriously, at the same time, the pressure of people in the current society has caused more and more people to sleep less and less, and the quality is getting worse, especially the sleep quality of the elderly is worse, and the noise is caused by other than their own body One of the main reasons for short, poor quality

Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with illustrations and specific embodiments.

[0019] refer to figure 1 , figure 2 As shown, this kind of noise reduction device includes a box body 1 and a base 2, the box body 1 is installed on the base 2, the box body 1 is ellipsoidal and is composed of an upper sphere and a lower sphere, the box body 1 The edge is provided with a fixed shaft 13, and the fixed shaft 13 is located at one end of the long radius, and one side of the upper sphere and the lower sphere is connected by the fixed shaft 13 on the edge of the casing 1, and the other side of the upper sphere and the lower sphere is not connected, and the upper sphere and the lower sphere are connected. The lower sphere can be combined into an ellipsoid, and the sphere can be separated from the lower sphere by the ...

Abstract

A noise reducing device comprises a box and a base. The box is arranged on the base. The box is in an ellipsoid shape and is composed of an upper sphere and a lower sphere. The edge of the box is provided with a fixed shaft. The upper sphere and the lower sphere can be combined to form an ellipsoid. Through the other end of the fixed shaft, the upper sphere and the lower sphere can be separated; the air in the gap can be exhausted by a vacuum pump to change the concentration of air in the gap so as to form a vacuum environment in the gap, the noise is insulated by the vacuum, at the same time, the inner sphere and the outer sphere are provided with a homo-polar polar plate, the homo-polar plates will generate a repulsion force (homo-polar repulsion theory) to counteract the atmospheric pressure, thus the decibel value of noise in the box is smaller than a preset value, the quality of sleep and rest is improved, the noise pollution is reduced; an air duct is arranged in the base arranged on the lower end of the box, the air duct is bent to an angle of 90 to 180 degrees to impede the sound transmission, and thus the air duct can supply air to the box and insulates the sound at the same time.

Description

technical field [0001] The invention relates to the field of noise elimination, in particular to a noise reduction device. Background technique [0002] Since the industrial revolution, the creation and use of various mechanical equipment has brought prosperity and progress to human beings, but at the same time it has also produced more and more noise. Noise can not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work; with the development of urbanization, the noise pollution generated by various automobile industries and electrical equipment is also increasing. Seriously, at the same time, the pressure of people in the current society has caused more and more people to sleep less and less, and the quality is getting worse, especially the sleep quality of the elderly is worse, and the noise is caused by other than their own body One of the main reasons for short, poor quality. The inventio...
