Microphone device (12) comprising at least one
microphone (14) with a receiving diaphragm (16) for detecting ambient sound (24) from the environment of a motor vehicle (10) and with a
transducer unit (18) for converting the detected ambient sound (24) into a
signal corresponding to the ambient sound (24), wherein the
signal is configured to generate an interior sound corresponding to the ambient sound (24) by means of a
loudspeaker device for the motor vehicle (10) in an interior of the motor vehicle (10), characterized in that the receiving diaphragm (16) is designed as a motor vehicle component for a mirror, through which an outer surface of the motor vehicle (10) is provided in a predetermined installation state,which the ambient sound (24) excites to a
mechanical vibration (26) corresponding to the ambient sound (24) and which transmits the
mechanical vibration (26) to a
signal generating element (20) of the
transducer unit (18) to generate the signal, wherein the receiving membrane (16) is designed as a mirror surface of an external mirror of the motor vehicle (10).
