PROBLEM TO BE SOLVED: To provide a bone conduction speaker with excellent acoustic characteristics and quality. SOLUTION: The bone conduction speaker includes: a frame with a vibration transmission plate; a pot-shaped yoke which is fixed to an inner wall of the frame by a movable support body; a magnet which is fixed to the bottom surface of the yoke; and a coil, one end of which surrounds at least a part of the side surface of the magnet, and the other end of which is fixed to the vibration transmission plate. The bone conduction speaker is used to be brought into contact with human skin. COPYRIGHT: (C)2011,JPO&INPIT
