Abstract:
An electronic device comprising a substrate, a cover delimiting at least a part of a main surface of the substrate to thereby form a cover-substrate arrangement enclosing a hollow space and having a through hole, an electroacoustic transducer configured for converting between an electric signal and an acoustic signal and being mounted on the substrate acoustically coupled with the hollow space in such a way that the hollow space constitutes a back volume of the electroacoustic transducer, wherein the electroacoustic transducer provides an acoustical coupling between the hollow space and an exterior of the cover-substrate arrangement via the through hole, an electronic chip mounted within the cover-substrate arrangement and electrically coupled with the electroacoustic transducer for communicating electric signals between the electronic chip and the electroacoustic transducer, and at least one electronic member mounted on the substrate within the cover-substrate arrangement and configured for providing an electronic function.
