US Patent 9014409 Battery door

An earcup assembly for a headset may include a housing having a first side adapted to engage the head of a user when in use and a second side opposite thereto. A recess provided in the second side of the housing receives and stores a battery. A battery door is arranged to slidably engage the second side of the housing such that the battery door may be moved between a first, open position in which the recess is accessible to a user and a second, closed position in which the recess is covered by the battery door. Preferably, the earcup assembly includes active noise reduction circuitry. One or a pair of such earcup assemblies may be arranged to form a headset, wherein the assemblies are coupled to a headband via yokes.
