Abstract
The utility model discloses an in-ear-type earplug protection rubber sleeve, belonging to the technical field of earphones. The in-ear-type earplug protection rubber sleeve mainly comprises a protection rubber sleeve body. The protection rubber sleeve body comprises an inner sleeve and an outer sleeve. The first sound passage of the inner sleeve is arranged on the inner sleeve in a penetrating way. The outer sleeve surrounds the external side of the inner sleeve. Each of the inner sleeve and the outer sleeve is provided with an open end and a connecting end which is connected with an end part. The in-ear-type earplug protection rubber sleeve has the advantages that the structure is simple, the protection rubber sleeve can be firmly combined with an earplug, impurities are not apt to be attached onto the protection rubber sleeve, cleaning is facilitated and the protection rubber sleeve can be widely used in the electronic industry such as earphone manufacture and the like.
Description
Technical field
The utility model relates to the earphone technical field, relates in particular to a kind of In-Ear earplug protective boot.
Background technology
Along with development of science and technology, communication and information industry develop rapidly, and in daily life, the use of electronic product more and more widely.Products such as mobile phone, notebook computer, Mp3 have all entered people life, in order under noisy occasion, to continue to use these products, need usually to connect earplug, but earplug fill in duct and can oppress the duct nerve, cause sense of discomfort to the user.Solution now commonly used is cover one sponges cover on earplug, and is also insecure but sponges cover combine with earplug to alleviate the compressing to duct, come off easily, and sponges cover adheres to impurity easily, is not easy to clear up.
The utility model content
Technical problem to be solved in the utility model is: a kind of In-Ear earplug protective boot is provided, and simple in structure, protective boot is combined with earplug firmly, be difficult for adhering to impurity again, be convenient to cleaning.
For solving the problems of the technologies described above, the technical solution of the utility model is: In-Ear earplug protective boot, comprise the protective boot body, cover and overcoat in described protective boot body comprises, put in described and be provided with first sound channel that runs through described interior cover, described outer sleeve is around in the described interior cover outside, and described interior cover and overcoat have an opening end and the link that the end links together.
As a kind of improvement, be provided with the gap that is used for being suitable for described overcoat distortion between described interior cover and the overcoat.
As further improvement, described link is provided with second sound channel, the described gap of the described second sound channel connection.
As a kind of improvement, the inboard of described interior cover is provided with the annular flange flange of the draw-in groove that is used for the described earplug of buckle.
After having adopted technique scheme, the beneficial effects of the utility model are: because protective boot adopts elastomeric material to make, can adopt the injection molding moulding, be convenient to produce in batches, user's wearing more comfortable has simultaneously reduced the pain of earplug compressing duct and outer surface smoother, be difficult for adhering to impurity, be convenient to cleaning; Because the protective boot body overlaps and overcoat in comprising, double-decker makes protective boot more firm with combining of earplug, difficult drop-off again.
Because be provided with the gap that is used for being suitable for the overcoat distortion between interior cover and the overcoat, protective boot can produce deformation, makes protective boot tightr with contacting of duct, has increased user's comfortable wearing sense.
Because link is provided with second sound channel that is communicated with gap between the overcoat with interior cover, makes that the sound permeability is stronger, has increased the efficiency of transmission of sound.
Because the inboard of interior cover is provided with the annular flange flange of the draw-in groove that is used for the buckle earplug, makes protective boot more firm with combining of earplug, difficult drop-off.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
