Abstract:
An electronic device with directional MEMS microphone assembly is provided, including a MEMS microphone capsule with a PCB affixed thereto, and a housing affixed to the PCB. The microphone assembly includes a first internal port and a second internal port through the PCB, wherein the first and second internal ports fluidically communicate with the MEMS microphone capsule. The microphone assembly further includes first and second external ports through the housing, wherein the first external port is offset from the first internal port in an offset direction perpendicular to a thickness direction of the microphone assembly. The microphone assembly further includes first and second cavities located between the PCB and the housing, wherein the first cavity fluidically communicates with the first internal port and the first external port, and the second cavity fluidically communicates with the second internal port and the second external port.
