  • Patent number: 8036407
    Abstract: An embodiment provides a continuous wear hearing device to be worn entirely within the ear canal, comprising a receiver assembly sized to be positioned in the bony portion of the canal, a battery assembly and a microphone assembly. The receiver assembly includes a receiver for supplying acoustic signals to the tympanic membrane. The battery assembly is coupled to the receiver assembly and includes a metal-air battery and a battery vent. The microphone assembly is coupled to the battery assembly and includes a microphone and a microphone sound port. The sound port faces a medial direction with respect to the canal. The orientation and position of the microphone in the canal are configured to reduce fouling of the port by cerumen. The positioning of the microphone assembly defines an air cavity disposed between the microphone assembly and the battery assembly with the port and the vent fluidically coupled to the cavity.

  • Patent number: 7551747
    Abstract: Embodiments of the invention provide a protective cap assembly for a CIC hearing aid. The assembly comprises a perforated cap configured to be mounted over the lateral end of the hearing aid to protect the hearing aid from contaminants. At a least a portion of the cap includes a protective coating and a plurality of perforations. The placement and size of the perforations can be configured to provide sufficient aeration and drainage to reduce a relative humidity of the cap interior when the hearing aid is positioned in the ear canal. The perforations also operate as sound conduction channels for conducting sound to the cap interior. The perforations have a minimum size wherein a single perforation provides sufficient acoustic transmittance to a hearing aid component such that a hearing aid performance parameter is not substantially adversely affected. They can also be configured to provide splash protection for the cap interior.
