Abstract
A MEMS component includes a MEMS sound transducer having a membrane structure and an assigned counterelectrode structure, and a circuit unit, which is electrically coupled to the MEMS sound transducer and which in a first operating mode of the MEMS sound transducer in the audio frequency range detects an audio output signal of the MEMS sound transducer on the basis of a deflection of the membrane structure relative to the counterelectrode structure, the deflection being brought about by an acoustic sound pressure change, and in a second operating mode of the MEMS sound transducer in the ultrasonic frequency range to drive and read the MEMS sound transducer as an ultrasonic transceiver.
