PURPOSE: A speaker using a circular type asymmetric driving method is provided to improve a frequency response characteristic and a sound effect by forming a vibration plate having an outer block of a circular shape, an asymmetric driving point, an asymmetric frame. CONSTITUTION: A speaker is formed with an asymmetrically circular type vibration plate(27), a circular frame(30), a symmetric or an asymmetric damper(22), a gasket(28), and a component(33). The asymmetrically circular type vibration plate(27) and the circular frame(30) have an outer block of an elliptical shape, respectively. The circular frame(30) is used for supporting the outer block of the asymmetrically circular type vibration plate(27). A voice coil is adhered on an arbitrary point of the remaining region except for a center of a circle of the asymmetrically circular type vibration plate(27). The circular frame(30) has an asymmetric structure. The asymmetric damper(22) has the asymmetric structure.
