PROBLEM TO BE SOLVED: To provide a headphone the cable of which does not run short in length even when a voice output apparatus is placed to either of left and right sides. SOLUTION: Ear pads 3R, 3L are respectively provided with connectors 5R, 5L. The connectors 5R, 5L respectively include terminals L, R, G, the terminal L is used for a left side sound signal, the terminal R is used for a right side sound signal, and the terminal G is used for grounding. Then the terminal L in the connector 5R and the terminal L in the connector 5L, the terminal R in the connector 5R and the terminal R in the connector 5L, and the terminal G in the connector 5R and the terminal G in the connector 5L are respectively coupled to each other by wires passing through a connection unit 4. Thus, even when the cable from the voice output unit (player) is connected to either of the connectors 5R and 5L, a normal sound is delivered to the headphone 1. COPYRIGHT: (C)2006,JPO&NCIPI |
