PROBLEM TO BE SOLVED: To provide a "speaker system" for suppressing force, which can be the cause of a vibration, generated when air moved forward/backward by the vibration of a diaphragm in a speaker body passes through a cylindrical body, while keeping the original function of the cylindrical body having a spiral partitioning board. SOLUTION: The speaker system 10 includes: the speaker body 11; the cylindrical body 13 for introducing a sonic wave from the speaker body 11; and the spiral partitioning board 14 arranged inside the cylindrical body 13. The spiral partitioning board 14 includes: a first spiral part 141 and a second spiral part 142 where spiral directions are respectively opposite. COPYRIGHT: (C)2011,JPO&INPIT
