3.In addition, the porosity of the polyureas aeroge of the aeroge ear plug 100 of present embodiment and specific surface area also constantly change thereupon.
The micro-nano loose structure become with self-assembly due to the polyureas nanofiber in polyureas aerogel layer can effective attenuation acoustic wave energy, and therefore, the aeroge ear plug 400 of embodiment 5 can reach the effect of sound insulation and noise reduction, and soundproof effect is good.
The main body of the aeroge ear plug of the application comprises at least one section of sound insulation section, and sound insulation section is made up of polyureas aeroge.It should be noted that, main body can comprise multistage sound insulation section, and wherein, not every sound insulation section is all be made up of polyureas aeroge, as long as there be at least one section of sound insulation section to be made up of polyureas aeroge.In addition, when main body comprises the sound insulation section that multistage polyureas aeroge makes, the density of the polyureas aeroge of every section of sound insulation section can be identical, also can be different; When density is different, density can be increased gradually to the other end by one end of aeroge ear plug or reduce, also can in changing arbitrarily; The density of the polyureas aeroge of adjacent two sections of sound insulation sections is identical or different.It should be noted that, the density of the polyureas aeroge of the application is not limited with above-described embodiment, can also be 0.016g/cm
3~ 0.65g/cm
3between any number (comprising two endpoint values).
In addition, the porosity of the polyureas aeroge of the aeroge ear plug of the application can also be 35% ~ 99.9%, and the specific surface area of polyureas aeroge can also be 10m
2/ g ~ 1000m
2/ g.
The shape of the aeroge ear plug in above-described embodiment is column type or bullet-shaped, but the shape of the aeroge ear plug of the application is not limited thereto, can also become other shape according to the profile design of ear, such as, can also be T-shaped or 7 fonts etc.Same, the size of the aeroge ear plug of the application can design according to real needs.
In addition, the aeroge ear plug of the application can be used alone, and also can have in the arranged outside of main body and be wrapped on body and the external member suitable with body, external member and aeroge ear plug with the use of.The ratio of the thickness of external member and the diameter of aeroge ear plug is 0.1:100 ~ 5:1.External member can be made up of silica gel, polyurathamc or other materials with certain pliability.
Tradition aeroge ear plug need to pinch flat after fill in ear, and treat its low resilience, be full of fill up external auditory meatus completely, therefore, easily certain pressure is caused to external auditory meatus, after the time is slightly long, wearer has obvious discomfort, and this is sacrificing the soundproof effect obtained under the prerequisite of comfortable wearing sense.But the aeroge ear plug of the application urea aeroge of getting together for fun is made, and non-resilience type aeroge ear plug, directly puts into external auditory meatus by it during use, not only wears conveniently, also to external auditory meatus skin build-up of pressure, can not be conducive to application.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
