Abstract:
An ear pad to be mounted to a base body to which a speaker unit is fixed includes an elastic body in which a plurality of elastic members having different coefficients of restitution are laminated together in a sound emitting direction of the speaker unit. A skin material covers an exterior of the elastic body. The elastic body includes a first elastic member arranged at a side of the base body, and a second elastic member laminated on and fixed to the first elastic member. The first and second elastic members respectively have ring shapes having a substantially same external diameter. The second elastic member has an inner peripheral surface having a different dimension compared to an inner peripheral surface of the first elastic member, and has a portion having a larger inner diameter than an inner diameter of the first elastic member.
