PROBLEM TO BE SOLVED: To provide a bone conduction speaker system that makes it possible to listen to music etc., without any sound leak to the outside when a bone conduction speaker is in use, and does not drive the bone conduction speaker or reduces the speaker output when not in use to eliminate harmful effects of sound leak. SOLUTION: The bone conduction speaker system comprises an audio signal input means, bone conduction speakers 2a and 2b which output audio vibrations based upon a signal inputted from the input means, and a speaker holding part 4 which holds the bone conduction speakers, and is characterized in that an abutting sensor 3 which detects the head abutting against the bone conduction speakers is arranged.
