The present invention relates to an earphone having a function of semi-automatically opening and closing an external sound and, more particularly, to an earphone having a function of semi-automatically opening and closing an external sound, which allows an external sound to be introduced in the earphone by communicating the inside of the earphone with the outside thereof through a semi-automatic operation process. The earphone having a function of semi-automatically opening and closing an external sound includes: a housing having a sound source passage opened in one direction therein, including a speaker mounted on the sound source passage, and having a communication hole formed on the outer peripheral surface to communicate the sound source passage with the outside; a rotating part rotatably mounted on the outer peripheral surface of the housing, and having a through hole communicating with the communication hole to communicate the sound source passage with the outside; and an elastic member mounted on the housing to add elasticity to the rotating part, wherein the communication hole and the through hole communicate with each other by rotation of the rotating part so as to communicate the sound source passage with the outside, and the elastic member adds elasticity to the rotating part such that the rotating part is semi-automatically rotated in a remaining section when the rotating part is rotated by a predetermined angle by an external force. |
