Zusammenfassung:A microphone assembly for a vehicle headliner includes a housing arranged to be received within a substrate layer of the headliner and having an upper portion and a lower portion. A circuit board is mounted in the upper portion and has a microphone element coupled thereto. An insert bracket includes a base and a shaft member extending upwardly therefrom, the base having a plurality of apertures aligned with the shaft member, wherein the shaft member engages the lower portion to connect the insert bracket to the housing. A sealing gasket having at least one channel defining an air path extending therethrough is arranged to be received within the shaft member and extend between the base and the upper portion, providing acoustic sealing between the insert bracket and the housing such that the air path directs sound from a cabin of the vehicle through the apertures to the microphone element.
