MICROPHONE ASSEMBLY WITH BARRIER TO PREVENT CONTAMINANT INFILTRATION
摘要
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.
