An object of the invention is to solve a problem that a cable exposed to an outside of a sound-emitting unit is tangled in fingers. In order to achieve the object, a headphone (1) includes: a sound-emitting unit (2) housing a speaker (48) having a diaphragm (49); and a cable unit (43) configured to transmit an electric signal to the speaker. The cable unit detachable from the sound-emitting unit is inserted in the sound-emitting unit from a bottom of the sound-emitting unit, disposed at an axially outer side than the diaphragm in a sound radiation direction of the diaphragm within the sound-emitting unit, and pulled from a top of the sound-emitting unit to an outside of the sound-emitting unit.


The merging support device is loaded on a movable body and acquires a current position of the movable body. The merging support device presents the recommended merging area when the movable body is on the merging lane. The recommended merging area is an area on the main lane where merging is recommended, and is preferably an area of a predetermined distance from an ending position of the merging lane.
