    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.

    Abstract: A microphone packaging assembly (100) provides a printed circuit board (pcb) (106) for coupling to a microphone device (102) having a bottom acoustic port (104). The pcb provides an acoustic port opening (108) which aligns with the bottom acoustic port (104) of the microphone device (102). A solder pad pattern (110) is disposed on the pcb (106). The solder pad pattern (110) is configured to provide both electrical connection (114) and an incomplete solder seal (116) having purposeful acoustic leak to the microphone device (102). A conformable coating (126) provides a seal to the purposeful acoustic leak. A single acoustic test can be performed to detect proper environmental protection and acoustic sealing of the packaged assembly (100).
