<P>PROBLEM TO BE SOLVED: To provide a small-sized and lightweight loudspeaker with which a plurality of persons are capable of simultaneously listening to sounds generated from earphones, and which does not include any lead wire or connector. <P>SOLUTION: The loudspeaker 1 includes an eddy-like sound conduction path 4 of which a spatial cross-sectional area becomes larger gradually from a starting terminal portion 4a and an ending terminal portion 4b, and earphone mounting portions 3 arranged oppositely at positions across the starting terminal portion 4a of the sound conduction path 4. The sound conduction path 4 is formed from a partition 14 which is formed like an eddy, and cover members 12, 13 holding the partition 14 from both sides, and each of the earphone mounting portions 3 is formed in shape of recess corresponding to an outer surface shape of an earphone to be mounted. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
