Abstract
A headphone includes a pair of ear cup assemblies attached to a headband. Each ear cup assembly includes a cushion, an earplate, a back plate and an acoustic transducer. These elements snap together and are held together by integral fasteners. Each ear cup assembly is attached to the headband by a ring-shaped yoke which is entrapped between the assembled back plate and ear plate. The result is a durable, lightweight structure which is easy to assemble on a mass production basis.
