Patent ID: 8705776

Claim:
A microphone package, comprising: one MEMS microphone component having a microphone diaphragm; one housing having a housing base and a housing cover, the housing enclosing the back-side volume of the microphone component, wherein an acoustic access channel to the microphone diaphragm is provided in the housing which is closed off with respect to the back-side volume and which connects at least one sound opening in the housing to one side of the microphone diaphragm; and an interposer, which is mounted inside the housing and which defines the acoustic access channel to the microphone diaphragm in that the interposer is coupled to the sound opening in the housing, and has at least one exit opening above which the microphone component together with the microphone diaphragm is mounted; wherein the interposer is configured as an essentially flat intermediate carrier having a peripheral convexly curved edge region, and wherein the interposer is connected to the housing base via its convexly curved edge region in a pressure-tight manner so that together with the housing base it forms the acoustic access channel, and at least the exit opening in the acoustic access channel is configured as a passage opening in the interposer.
