The vibration-lead plate includes: a coil plate-spline, mounted between a voice coil plate having a voice coil formed in the shape of a spiral track and a vibration plate to vibrate according to the movement of the voice coil plate for generating sound, and formed in the center so as to be adhered to the voice coil plate; an edge-spline, connected to one side of the coil plate-spline and the edge of the vibration plate so as to variably correspond to vibrations; and a vibration plate outside portion, connected to one side of the edge-spline and adhered to the outside portion of the edge of the vibration plate.
