Abstract:
A replaceable earmuff system with an arch-shaped member (headband) and first and second earmuff assemblies that are removably attached to the arch-shaped member. Each earmuff assembly has inner and outer earmuff housings and a spring. The inner earmuff housing is circular in shape with a flat base plate and a lip that extends around the perimeter of a first side of the inner earmuff housing. A circular protrusion, which has two opposing L-shaped slots, is situated in the center of the inner earmuff housing on a second side of the inner earmuff housing. The outer earmuff housing is saucer-shaped with a concave inner side and a convex outer side. A circular collar with two opposing keys that fit within the L-shaped slots is situated in the center of the concave inner side of the outer earmuff housing. The spring fits within the circular protrusion and the circular collar.
