Abstract
An attenuation mechanism for an electronic device is presented. The attenuation mechanism includes an outer member that has an inner member oriented axially within the outer member. The inner member has an axial twist that causes a line of sight blockage between an exterior and an interior of a housing of an electronic device when the attenuation mechanism is mounted through the housing, such that sound and electromagnetic radiation is attenuated without obstructing cooling air that is flowing through the housing.
