Claims4
An ear tip, which is mounted on one side of an earphone and configured to be inserted into a wearer's external auditory canal to stably fix a position of the earphone, the ear tip comprising:
- a main body part having a hollow cylindrical structure corresponding to an outer circumferential surface of the earphone;
- a coupling part formed to have a ring structure along an inner circumferential surface of an upper portion of the main body part and having a protrusion structure corresponding to a recessed coupling structure formed on the outer circumferential surface of the earphone;
- one or more protrusion parts formed to have a ring structure along an inner circumferential surface of a lower portion of the main body part and having a protrusion structure protruding by a predetermined height, the protrusion part being disposed to be spaced apart from the coupling part by a predetermined distance;
- and
- an external auditory canal contact part having a structure radially protruding from an outer circumferential surface of a lower end of the main body part and extending upward by a predetermined height, the external auditory canal contact part being configured to contact with an inner surface of the wearer's external auditory canal,
- wherein a plurality of the protrusion parts is formed on the inner circumferential surface of the lower portion of the main body part so as to be spaced apart from one another by a predetermined distance, and
- wherein the plurality of the protrusion parts are spaced apart from one another by the predetermined distance and grouped into a single group, and protruding lengths of the plurality of the protrusion parts constituting the single group relatively increase toward a lower side, a middle side, or an upper side.
