Abstract
The invention aims to provide a rubber single-frequency noise barrier which can effectively reduce vibration and furthermore can convert a low single frequency to a white noise. The rubber single-frequency noise barrier according to the invention comprises a top seat, a bottom seat, and a rubber member which is arranged between the top seat and the bottom seat. The rubber single-frequency noise barrier is characterized in that the rubber member is internally provided with a plurality of sealed hard containers; and the containers are filled with water. In use, the rubber single-frequency noise barrier is used for mounting and fixing an easy-vibrating component. When the component vibrates, the self elasticity of the rubber member absorbs partial vibration, thereby weakening an integral noise. Furthermore, if the component performs a ruled single-frequency vibration, the vibration drives the water in the containers so that the water vibrates in the containers, thereby reducing vibration energy. Most important, vibration of the water generates the white noise, thereby converting the vibration energy of the single-frequency vibration to the white noise, shielding the boring single-frequency noise and improving the comfort degree of the people.
Description
Technical field
The invention belongs to noise Barrier Technology field, be related specifically to a kind of macintoss audio-frequency noise obstructing instrument.
Background technique
In vehicle traveling process, all parts of automobile inevitably produces certain noise, and in order to intercept noise, people carry the parts of easily vibration usually with rubber pad, to make vibration weakening during component working, thus reduce noise.But the rubber pad of simple structure is difficult to eliminate various vibration, particularly the poorest to the barriering effect of low-frequency vibration, correspondingly, this kind of rubber pad is also just difficult to the single-frequency noise eliminating low frequency.Driver, in startup procedure, if will hear single-frequency noise all the time, is easy to produce irritated mood.In addition, if the passenger in automobile needs to have a rest, single-frequency noise also can hinder people to fall asleep.On the contrary, although belong to noise together, white noise but has the effect helping to focus one's attention on and sleep, therefore, when low frequency single-frequency noise thoroughly cannot be shielded, if low frequency single-frequency noise is converted into white noise, the travelling comfort impression improving people also can be contributed to.
Summary of the invention
The object of the invention is to propose one can effective vibration damping, and low frequency single-frequency noise can be converted into the macintoss audio-frequency noise obstructing instrument of white noise.
Macintoss audio-frequency noise obstructing instrument of the present invention comprises footstock, base and the rubber body between footstock, base, and it is characterized in that described rubber body inside is provided with several airtight rigid containers, described container content has water.
In use, the parts of fixing easily vibration are installed with macintoss audio-frequency noise obstructing instrument.When component vibration, the elasticity that rubber body itself has can absorption portion be vibrated, thus weakens overall noise, in addition, if what parts sent is the vibration of regular single-frequency, so this vibration will drive the water in container, and water is beated in container, thus reduce the energy of vibration, crucially, beating of water can produce white noise, thus the Conversion of Energy vibrated by single product is white noise, cover irritating single-frequency noise, improve the comfort level of people.
If the amount of water is suitable, will produce with single-frequency noise and resonate, thus seriously undermine single-frequency noise, in the present invention, the amount of the water that each container content described has is all not identical, so just can cover more single-frequency frequency as much as possible, even people can also set the number of water in container especially according to the vibration frequency of institute's load-bearing component, accomplish to transform single-frequency noise targetedly.
Further, shape, the size of each container described are all not identical, produce more uniform white noise to enable rubber body.
Further, the internal surface of each container described is provided with irregular projection, when water is beated and projection collide, not only can cut down rapidly the energy (i.e. the energy of component vibration) of water, and the noise of generation can be made more there is no rule, flood single-frequency noise.
Further, the outer surface of each container described is provided with several and points to different needle bodies, to enable the noise of the water in container to multiple directions transmission, reduces the regularity of the vibration of whole noise obstructing instrument, thus reduces secondary single-frequency noise.
Macintoss audio-frequency noise leaf barrier structure of the present invention is simple, can effective vibration damping, and low frequency single-frequency noise can be converted into white noise, thus covers irritating single-frequency noise, and the comfort level of raising people, is very suitable for the vibration damping of automobile.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of macintoss audio-frequency noise obstructing instrument of the present invention.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the macintoss audio-frequency noise obstructing instrument of the present embodiment comprises footstock 1, base 2 and the rubber body 3 between footstock 1, base 2, described rubber body 3 inside is provided with several airtight rigid containers 4, described container 4 is built with water, and the amount of water that the shape of each container 4, size and its inside are equipped with is all not identical.
In use, the parts of fixing easily vibration are installed with macintoss audio-frequency noise obstructing instrument.When component vibration, the elasticity that rubber body 3 has itself can absorption portion be vibrated, thus weakens overall noise, in addition, if what parts sent is the vibration of regular single-frequency, so this vibration will drive the water in container 4, water is beated in container 4, thus reduces the energy of vibration, crucially, beating of water can produce white noise, thus covers irritating single-frequency noise, improves the comfort level of people; The amount of the water that the shape of each container 4, size and its inside are equipped with is all not identical, rubber body 3 so just can be made can to produce more uniform white noise, and cover more single-frequency frequency as much as possible, even people can also set the number of water in container 4 especially according to the vibration frequency of institute's load-bearing component, accomplish to transform single-frequency noise targetedly.
The internal surface of each container 4 is provided with irregular protruding 5, collides, not only can cut down rapidly the energy (i.e. the energy of component vibration) of water, and the noise of generation can be made more not have rule, flood single-frequency noise when water is beated with protruding 5.
The outer surface of each container 4 is provided with several and points to different needle bodies 6, to enable the noise of the water in container 4 to multiple directions transmission, reduces the regularity of the vibration of whole noise obstructing instrument, thus reduces secondary single-frequency noise.
