PURPOSE: A speaker is provided to reinforce the rigidity of an outer rim of a coupler by forming a first bent portion in the outer rim, thereby suppressing separated vibration of the coupler. CONSTITUTION: A housing (110) comprises a support plate (111) and a case that are combined with each other. A magnetic circuit part comprises a yoke, a magnet, and a pole piece. A sound generation part comprises a vibration plate (131), a coupler (133), and a voice coil. The outer periphery of the vibration plate is coupled to the case by an edge (137). A first bent portion is formed in the outer rim of the coupler to reinforce the rigidity of the outer rim. |
