Abstract
A modular hearing aid to fit in the user's ear, having a shell, a faceplate fixed to the shell, and an electronic module removably snapped into the faceplate. The module includes an open-topped battery compartment which is closed by a lid hinged to the faceplate rather than to the module. This eliminates a bulky hinge on the module and allows a smaller snap fastener between the module and faceplate. The volume control on the module projects through an opening in the closed lid.
