Abstract (en)
[origin: WO02074010A1] A microphone is equipped with an element (13) for mesuring the distance to a sound emitter, for example the face of an artist. The distance measurement element (13) can be part of the acousto-electric transducer (7) of the microphone, and it can be a piezo-electric ultrasound echo range finder (15, 16).
