Abstract
A microphone assembly includes a printed circuit board that defines a tab that is configured to extend into an opening defined by a substrate layer of a headliner. The microphone assembly includes a microphone element mounted on the tab. The microphone assembly includes a sealing element that surrounds the tab and the microphone element and is configured to fill the opening and define an air path from a cabin side of the substrate layer to the printed circuit board or the microphone element.

A microphone assembly comprising:
- a printed circuit board (PCB) defining a tab that extends from the PCB and is configured to extend into an opening defined by a substrate layer of a vehicle headliner;
- a microphone element directly mounted on the tab such that a port of the microphone element for receiving sound waves is oriented toward the tab;
- and
- a sealing element surrounding the tab and the microphone element and being configured to fill the opening and define an air path between a surface of the sealing element exposed to air and the tab.
A microphone assembly comprising:
- a printed circuit board (PCB) defining a tab that is configured to extend into an opening defined by a substrate layer of a headliner;
- a microphone element directly mounted on the tab and including a port for receiving sound waves;
- and
- a sealing element surrounding the tab and the microphone element and configured to fill the opening and define an air path between a surface of the sealing element exposed to air and the port of the microphone element.
A headliner assembly for a vehicle comprising:
- a headliner including:
- an acoustically transparent layer that is exposed to a cabin of the vehicle;
- and
- a base substrate layer defining an opening that extends through the base substrate layer;
- and
- a microphone assembly including:
- a printed circuit board (PCB) defining a tab configured to extend into the opening,
- a microphone element directly mounted to the tab, and
- a sealing element configured to fill the opening, surround the tab and the microphone element and define at least a portion of an air path between the cabin and the microphone element.
