Abstract:
A device with a microphone and a condensation collection apparatus to prevent migration of condensation to the microphone is provided. The device comprises a microphone; a board having an acoustic port therethrough, the microphone positioned to accept sound through the acoustic port; a moisture-resistant, acoustically transparent membrane over the acoustic port; an outer membrane that receives the sound for the microphone, the outer membrane being non-permeable to at least moisture; and a condensation collection apparatus between the outer membrane and the acoustically transparent membrane. The condensation collection apparatus comprises: an aperture through which the sound from the outer membrane passes; and one or more condensation collection features, at an outer-membrane facing side of the condensation collection apparatus, configured to: collect condensation that migrates from an inner side of the outer membrane; and prevent migration of the condensation, that is collected, through the aperture.
