Abstract
In at least one embodiment, a microphone assembly including an enclosure, a first printed circuit board (PCB) and a microphone assembly is provided. The microphone assembly includes a sub-casing, a micro-electro-mechanical systems (MEMS) transducer, and a second PCB. The MEMS transducer positioned in the sub-casing and the second PCB supports the MEMS transducer. The first PCB defines a first acoustic path positioned below the second PCB and the MEMS transducer. The second PCB defines a first audio port positioned directly below the MEMS transducer. The enclosure defines a first acoustic opening that is positioned directly below the first acoustic path to enable an audio input signal to pass through the first audio port and to an underside of the MEMS transducer. The enclosure defines a second acoustic opening that is positioned at a distance of between 3 to 30 mm from the first acoustic opening.
