PURPOSE: A speaker is provided to compress a damper by using a pressing piece which is formed in a frame when the damper is combined with the frame. CONSTITUTION: A magnetic circuit part(120), which generates a magnetic force, is combined with the lower side of a frame(110) outside a penetration hole(111). A vibrating part(130), which interacts with the magnetic circuit part, generates electric force inside the frame. The magnetic circuit part comprises a plate(121), a magnet(123), and a yoke(125). The vibrating part comprises a voice coil(131), a vibration plate(133), and a damper(135). The outer circumference of the damper is combined with the frame. The inner circumference of the damper is combined with the central outer circumference of a bobbin(131a). The damper prevents the left/right movement of the voice coil when the voice coil is vibrated. |
