摘要

Aspects, to provide a continuous wear hearing device that includes a microphone assembly receiver assembly, and battery assembly, which is sized to be placed in the bony portion of the ear canal, the ear canal completely be (entirely) wear. The receiver assembly includes a receiver for providing an acoustic signal to the eardrum. Battery assembly includes a battery vent and metal-air battery and is connected to the receiver assembly. Microphone assembly includes a microphone and voice port and microphone, is connected to the battery assembly. Voice ports, facing inward direction with respect to the ear canal. Orientation and position of the microphone in the ear canal is configured to reduce the contamination of the port by earwax. The position of the microphone assembly, and defining a cavity disposed between the battery assembly and a microphone assembly, and vent port is coupled to the cavity fluidly.
