HEADPHONE, ELECTRONIC DEVICE, CORD WINDING DEVICE, AND CORD WINDING METHOD

摘要

An input cord used for a headphone or an electronic device is wound up around a winding device such as a reel, and easy assembling is realized without using any jig when a commutator mechanism for relay to another D/U through the longer earbud cord is attached. A terminal board having a metal current-collecting ring is provided to the lower flange of a reel in each of left and right headphone housings, and a contact (brush) is provided to the housing (2) at the position opposed to the terminal board.
