摘要：
A telephone set base, for both wall and desk top mounting, has an elongate plastic molded base plate and a top housing. To improve stability a flat metal weight is positioned on the base plate and is spaced a small distance from the base plate to form an acoustic chamber. A speaker is mounted on the weight. A printed circuit board is mounted over the weight and modular jacks are attached to a flexible circuit member which connects to the printed circuit board, speaker, and other items. Recesses are formed in the base plate to provide for alternative arrangements of line cords and plug-in mounting on a wall. Slots in the base plate provide access to the recesses for cords entering at the ends of the base plate. A battery housing is provided.
