Abstract
A damper for a loudspeaker has an improved linearity of the amount of strain caused by the vibrational energy to vibrational energy exerted on the damper to enable the loudspeaker to reproduce sounds in a high fidelity. The damper is formed such that the modulus of elasticity with respect to a direction perpendicular to the surface of the damper is uniform on a circle with its center at the center of the damper, and portions respectively on concentric circles with their centers at the center of the damper are different in modulus of elasticity with respect to a direction perpendicular to the surface of the damper from each other.
