Abstract:
Sound is blocked from entering a sound pickup area of a sound pickup device by placing a sound control structure adjacent to the sound pickup area. The sound control structure can include a sound absorbing material which can be placed in a first position that blocks sound, or in a second position that allows sound to pass. The sound control structure can alternately include levers that engage buttons on the sound pickup area that enable or disable the sound pickup area.
