<P>PROBLEM TO BE SOLVED: To provide an earphone device which is excellent in fittingness and can provide more improved sound quality. <P>SOLUTION: In the earphone device, a housing 5 and a sound conduit 4 fitted projecting from the front of the housing are provided, the sound conduit 4 is arranged outside the front middle point P1 and a sound conduit tip part 4A is directed to be away from the housing front middle point P1. Consequently, when a user puts the earphone device on an ear, the housing never comes into contact with the antilobium and as the housing can be made wider than before, the diameter of a diaphragm in a driver unit put in the housing is increased, so that the user can listen to a sound of high sound quality while having a good feeling of wearing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
