  • Microphone assembly with barrier to prevent contaminant infiltration
    Patent number: 9078063
    Abstract: A microphone assembly includes a cover, a base coupled to the cover, a microelectromechanical system (MEMS) device disposed on the base. An opening is formed in the base and the MEMS device is disposed over the opening. The base includes a barrier that extends across the opening and is porous to sound. The remaining portions of the base do not extend across the opening.
