PURPOSE: An external sound inflowing earphone is provided to tilt not only the insertion part of an external auditory meatus but also an external sound inflow path by considering the design of a sound transmission path and ventilation, sound insulation, sound discharging, and the strengthening and relaxing of speaker vibration. CONSTITUTION: An earphone includes a body(100) and a wearing part(200). The body includes a speaker(150), which generates a speaker sound according to an electric signal and a cover which surrounds a speaker. A speaker sound path(210) transfers the speaker sound to an external auditory meatus in the body. The wearing part includes a cushion(240) which is worn in the external auditory meatus while being included in the holder surrounding the speaker sound path. The body includes one or more external sound paths which flow the external sound of the outside of the body in the body. The wearing part includes one or more transferring paths in which the external sound is transferred from the external sound path to the external auditory meatus. The external sound paths and the transferring paths respectively insulate the speaker and the speaker sound path with sounds.
