Abstract
A kind of novel duct-type earplug, comprise shell body, inner housing and earplug cover, the annular concave platform of described inner housing and shell body one end outer circumference surface forms interference fit, inside and outside shell forms a toroidal cavity, described inner housing is provided with a through major axis body relative to one end of shell body, this major axis is external is equipped with an earplug cover, described earplug cover comprises earplug cover body, first cover body, second cover body and the 3rd cover body, described first, second, 3rd cover body is ring taper, described first cover body, second cover body, 3rd cover body sets gradually along earplug cover outer circumference surface is descending from earplug cover near one end of inner housing.Owing to adopting above-mentioned structural design, namely by inner and outer shell, and be placed on three grades of earplug covers on inner housing, the utility model is made to be easy to enter ear canal internal, not only obtain good seal, greatly improve comfort level, too increase the expression effect of earplug.
Description
Technical field
The utility model relates to ear phone technology field, especially a kind of novel duct-type earplug.
Background technology
Earphone as the necessary accessory of electronic product, enjoy people play a part in the process of the enjoyment that various electronic product brings very important.
Earplug in the past adopts hard material to make mostly, earplug is arranged on duct outside, by extruding ear's outline in case anti-avulsion falls; But, due to the difference in size of the external auditory meatus of different people, the earplug being unsuitable for wearer usually can bring sense of discomfort, sound insulation bad, leak the problems such as sound and earplug skid off from duct.Earplug to bring sense of discomfort problem to duct is worn for solving, people can be nested with silica gel sheath or sponges cover on earplug, although this settling mode solves the problem of sense of discomfort to a certain extent, but because silica gel sheath or sponges cover easily come off, not only thoroughly can not deal with problems, but also cause the high cost of earplug.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For the deficiencies in the prior art part, it is good that the purpose of this utility model is to provide a kind of soundproof effect, do not leak sound, not easily deviates from from duct, ensures the novel duct-type earplug of earplug comfortable wearing sense.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of novel duct-type earplug, comprise shell body, inner housing and earplug cover, the annular concave platform of described inner housing and shell body one end outer circumference surface forms interference fit, inside and outside shell forms a toroidal cavity, described inner housing is provided with a through major axis body relative to one end of shell body, this major axis is external is equipped with an earplug cover, described earplug cover comprises earplug cover body, first cover body, second cover body and the 3rd cover body, described first, second, 3rd cover body is ring taper, described first cover body, second cover body, 3rd cover body sets gradually along earplug cover outer circumference surface is descending from earplug cover near one end of inner housing.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, namely inner and outer shell is passed through, and the three grades of earplug covers be placed on inner housing, the utility model is made to be easy to enter ear canal internal, not only obtain good seal, greatly improve comfort level, too increase the expression effect of earplug.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, each label respectively: (1) shell body, (2) inner housing, (3) earplug cover, (4) annular concave platform, (5) major axis body, (6) earplug cover body, (7) first cover bodies, (8) second cover bodies, (9) the 3rd cover bodies.
Embodiment
The utility model is described in further detail to provide embodiment below in conjunction with accompanying drawing:
Refer to Fig. 1, a kind of novel duct-type earplug of the utility model, comprise shell body 1, inner housing 2 and earplug cover 3, described inside and outside shell is made up of rigid plastics, described inner housing 2 forms interference fit with the annular concave platform 4 of shell body 1 one end outer circumference surface, inside and outside shell forms a toroidal cavity, described inner housing 2 is provided with a through major axis body 5 relative to one end of shell body 1, an earplug cover 3 is equipped with outside this major axis body 5, described earplug cover is made up of silica gel, quality is soft, described earplug cover 3 comprises earplug cover body 6, first cover body 7, second cover body 8 and the 3rd cover body 9, described first, second, 3rd cover body is ring taper, described first cover body 7, second cover body 8, the diameter of the 3rd cover body 9 is respectively 14mm, 12mm, 10mm, described first cover body 7, second cover body 8, 3rd cover body 9 sets gradually along earplug cover outer circumference surface is descending from earplug cover 3 near one end of inner housing 2, the structural design of above, because the earplug cover adopting the silica gel of quality softness to make can make the utility model easily insert the inside of duct, meet the user demand of different people, there will not be the phenomenon that earplug comes off from duct, also there will not be and wear the senses of discomfort such as pain that earplug brings for a long time, also because the utility model is close to ear canal wall face, the environment that in duct, formation one is airtight can be made, there will not be sound insulation bad, leak the situation of sound, ensure that the expression effect of earplug.
Certainly, the utility model also has other to be out of shape.In a word, according to the prompting of above-described embodiment and the apparent variation made, and other every changes not departing from the utility model essence, all should be included within the scope described in claim.
