US 2019/0379955 A1 · Gradient Micro-Electro-Mechanical (MEMS) Microphone Assembly

Abstract

MEMS microphone assembly which is formed by the combination of front and rear single piece boots, which are configured to mate, and a MEMS microphone. The front boot includes two ports for receiving sound waves which are provided to ports of the MEMS microphone. The front boot includes two collars to form the ports and which are used to align the MEMS microphone assembly in a housing containing the MEMS microphone assembly. Acoustic tubes transfer the sound waves from the ports to the MEMS microphone. There can be air channels provided with the acoustic tubes to reduce microphonics. The front and rear boots contain recesses to capture the MEMS microphone to simplify alignment and assembly.

Dependent claims

A micro-electro-mechanical systems (MEMS) microphone mounting assembly comprising:

a three-dimensional front boot having a front side and a back side, the front side containing two ports for receiving sound waves, the back side containing a recess for receiving at least a portion of a MEMS microphone;
and
a three-dimensional rear boot having a front side and a back side, the front side configured to mate with the back side of the front boot and containing a recess for receiving the remaining portion of a MEMS microphone,
wherein when mated, the front boot and the rear boot form a seal and would capture a MEMS microphone, and
wherein two acoustic tubes in acoustic communication with the two ports are formed in the front boot, the rear boot or both to carry sound waves from the two ports to the recesses for the MEMS microphone.
