<P>PROBLEM TO BE SOLVED: To provide a headphone having a little likelihood to affect performance even when a foreign body enters between a bushing and a cord. <P>SOLUTION: A headphone 1 of a first embodiment includes a driver unit 4, a cord 3, housings 5, and a bushing 13. The driver unit 4 generates a sonic wave on the basis of a supplied audio signal. The cord 3 is connected to the driver unit 4 in order to supply the audio signal from an external part to the driver unit 4. The housings 5 store the driver unit 4 and also have cord insertion holes 10 for inserting the cord 3. The bushing 13 is a cylindrical body for protecting the cord 3 from disconnection due to bending by covering an outer peripheral surface 3a of the cord 3 with a gap g. The bushing 13 is attached to the cord insertion holes 10. An adhesion part 17 to adhere to the outer peripheral surface 3a of the cord 3 in a ring shape is formed on an inner peripheral surface 13a of the bushing 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
