摘要

Cochlear implant headpieces with improved moisture resistance. The headpiece comprises a housing (102) including a housing microphone aperture (124), a microphone (108) within the housing, a membrane (148) between the housing microphone aperture and the microphone, a cap (104) including a sound port (158) and a shield (168), the cap being removably connectable to the housing and the headpiece being protected from particulate and moisture ingress.

主权项

1. A cochlear implant headpiece for use with a cochlear implant, comprising:
a housing including a housing microphone aperture; a microphone carried within the housing and associated with the housing microphone aperture; a transmitter carried by the housing that transmits signals to the cochlear implant; a housing membrane between the housing microphone aperture and the microphone; and a cap, including a sound port and a cap membrane over the sound port, configured to be positioned on the housing such that the sound port and cap membrane are aligned with the housing microphone aperture; wherein the housing and cap are configured such that they will be removably connected to one another, with the entire cap membrane spaced apart from the housing membrane, when the cap is positioned on the housing.
