PROBLEM TO BE SOLVED: To make a speaker box thin while securing the duct length of a sound path required to reproduce a low-pitched sound area at a sufficient level in a speaker device having the sound path within the speaker box. SOLUTION: This speaker device comprises a main cabinet 11, a main cabinet cover 12 and a front cabinet cover 13 and has the speaker box 10 having a plurality of opening parts on the front cabinet cover 13, a tweeter speaker 15 and woofer speaker 16 provided inside the speaker box 10 matching with the opening parts and the sound path 14 for performing phase inversion of sound outputted from the rear face of the speaker 16 and emitting the sound to the front. In the sound path 14, one opening is disposed facing the rear face of the speaker 16 and the other opening is connected to a sound path opening part 13c, and the path is turned back by the prescribed number of times between the openings to form the sound path 14. This can reproduce a low-pitched area at a sufficient level and make the speaker box 10 thin. COPYRIGHT: (C)2005,JPO&NCIPI
