Abstract
The utility model relates to a sound-absorbing earplug, which is composed of a half-open flexible rubber coating (1) and a rubber plug (2). Nanometer sound-absorbing fiber (3) is arranged inside the flexible rubber coating (1), which is plugged by the rubber plug (2). The utility model is adaptable for the shapes of human ears, which ensures comfortable application. The nanometer fiber placed inside the utility model is capable of absorbing noise of various decibels, which thoroughly eliminates noise nuisance and does not affect normal voice transmission.
Description
Technical field
This utility model belongs to ear preventer field, especially relates to a kind of sound-absorbing earplug.
Background technology
Used sound-absorbing sound insulation earplug all is to adopt rubber, plastic or other material to add common sound-absorbing material, as compositions such as cotton fibers usually at present.The materials of this earplug have certain soundproof effect for common acoustic, but do not have deadening for bigger high-decibel noise, and the noise sound wave still can import tympanum into by earplug, and tympanum is worked the mischief.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sound-absorbing earplug, to improve the effect of sound-absorbing.
Technical scheme
This utility model provides a kind of sound-absorbing earplug, is made up of the flexible rubber lagging and the flexible rubber plug of an end opening, and the nanometer acoutic fibre board is housed in the flexible rubber lagging, is clogged by the flexible rubber plug.
Described flexible rubber plug is shaped as the nipple head.
The flexible rubber condom has some blades on every side as cylindrical, and the thickness of blade is attenuation gradually from the center of circle to the edge, and the diameter of blade becomes big by opening part gradually to the other end.
All has compressible microcellular structure on described flexible rubber lagging, flexible rubber plug, the blade.
The composite material of the material selection natural rubber of described flexible rubber lagging and rubber stopper, natural emulsion, silicone rubber, polyvinyl resin, EVA resin or these materials, the processing technique of selecting for use are die press technology for forming;
Described nanometer acoutic fibre board is electrostatic spinning nano porous fibre or the electrostatic spinning nano fiber that contains the plumbous granule of nanometer, nano carbon particle mass percent 3% ~ 30%, and selected material is polyester, polyethylene, polypropylene, polyacrylonitrile, cellulose fibre raw material.
Beneficial effect
The nipple shape rubber stopper of the rubber sleeve of this utility model outside adapts to the shape of people's ear, makes its adapted comfortable, and its inner nanofiber can absorb the noise of various decibels, and harm thoroughly abates the noise.
Because the several layers blade arranged, every layer of blade all with the auditory meatus driving fit, intercepted most volume, and each interlobate space stored air, form the transmission that air cushion has better been resisted high frequency noise, also do not influence the transmission of normal voice.
Since earplug be by the flexible rubber that certain restoring force is arranged make and its on have compressible microcellular structure, so in use compaction plug pleasant in, the earplug shape that can have more auditory meatus is slowly recovered and is sealed then, and sealing effect is better, reaches good noise reduction.

The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of sound-absorbing earplug, it is by the flexible rubber lagging 1 that includes nanometer acoutic fibre board 3, the rubber stopper 2 of sealing flexible rubber lagging 1 opening and the nanometer acoutic fibre board 3 of plug in flexible rubber lagging 1, and the cover body is equipped with 3 blades 4.
The composite material of the material selection natural rubber of flexible rubber lagging 1, rubber stopper 2 and blade 4, natural emulsion, silicone rubber, polyvinyl resin, EVA resin or these materials, the processing technique of selecting for use is a die press technology for forming, all has compressible microcellular structure on it.
Flexible rubber lagging 1 opening is the nipple head, and cover is as cylindrical, and middle hollow is put nanometer attraction fiber 3 to add, and the thickness of blade 4 is attenuation gradually from the center of circle to the edge, and the diameter of blade 4 becomes big by opening part gradually to the other end.
Nanometer acoutic fibre board 3 is electrostatic spinning nano porous fibre or the electrostatic spinning nano fiber that contains the plumbous granule of nanometer, nano carbon particle mass percent 3% ~ 30%, and selected material is polyester, polyethylene, polypropylene, polyacrylonitrile, cellulose fibre raw material.
