Abstract:
A System and method to provide a cost-effective implementation of a microphone package, very good microphone performance being achieved even with a high degree of miniaturization. A microphone package includes a MEMS microphone component having a microphone diaphragm, and a housing having a housing base and a housing cover, the housing enclosing the back-side volume of the microphone component, and an acoustic access channel to the microphone diaphragm being 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. An interposer is mounted inside the housing 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.
