PURPOSE: A coil type wire earphone winder is provided to improve feeling of wearing by a restoring force of a conventional coil type wire earphone and to supply an improved winder having good durability in comparison with a conventional reel type winder. CONSTITUTION: A coil type wire earphone winder includes a body(2) of the winder, a spring wire(5), a detent(7), a spiral spring(20), a winding reel(30). End of the spring wire(5) in the direction of the drawing is fixed to one end of the earphone through a central portion of the coil type wire and a portion of the coil type wire in the direction of jack is fixed to a predetermined groove of the body of the winder. When a user pulls the earphone to a desired position, a pitch of the coil type wire is extended and the spring wire(5) is drawn in the assembly of the winder. And then, if the earphone is released, the coil type wire generates a compressive force to restore an original shape thereof or retains the extended state retarded by the spring wire(5) positioned inside. A radius of curvature of the spring wire(5) is larger than the extended pitch of the coil type wire to thereby easily bend, to prevent the motion of the user and to prevent the deviation inside of the coil type wire.
