Headphone, Electronic Device, Cord Winding Device, and Cord Winding Method

摘要

An input cord used in a headphone apparatus and an electronic apparatus is wound around a winding device such as a reel, and assembly is facilitated without using jigs when a commutator mechanism relaying to a D/U on the other side through a passage cord is installed. A terminal board including metal slip rings is provided on the side of a lower flange of a reel in left and right headphone housings, and contact points (brushes) are provided on the side of a housing 2 at a position opposed to the terminal board.
