PURPOSE: A speaker is provided to reduce a collision of a tinsel wire to a vibrating plate by vibrating one end of the tinsel wire and the vibrating plate identically. CONSTITUTION: A speaker includes a frame(110) having penetration holes in a center thereof, a magnetic circuit portion(120), a vibrating portion(130), a damper, a terminal(140), a lug(160), and a tinsel wire(150). The magnetic circuit portion is attached to an outer portion of the frame outside of the penetration holes and generates a magnetic force. The vibrating portion includes a vibrating plate(131) and a voice coil which vibrates the vibrating plate in a reaction with the magnetic circuit portion when a power is supplied. An edge of the damper is coupled with an inner portion of the frame and a center of the damper is coupled with an outer circumference of the voice coil. One node of the terminal is implemented in a region formed by the frame, the vibrator and the damper. The other node of the terminal is implemented on an outer side of the frame and connected to an outer power source. The lug includes a connection slice(161) attached to an upper surface of the vibrator, a first connection slice(163), a connection slice(165), and a second connection slice in parallel with the vibrating plate. The tinsel wire transfers an outer power to the voice coil.
