Abstract: A flat panel speaker has a construction in which an actuator 10 vibrates a panel to radiate sound, the panel being held at a peripheral portion thereof on a frame by gaskets, wherein the gasket provided at a position opposite from a position at which the actuator is placed has a higher hardness than that of the gasket provided at another position. The side on which the gasket having the higher hardness is placed is a substantially fixed end to facilitate vibration of the panel, thereby improving sound quality.
