Abstract
La présente invention concerne un microphone, pourvu d'un élément (13) servant à mesurer la distance qui s'étend jusqu'à un émetteur sonore, tel que le visage d'un artiste. L'élément (13) de mesure de la distance peut être compris dans le transducteur acousto-électrique (7) du microphone, et il peut s'agir d'un télémètre (15, 16) à échos d'ultrasons piézo-électrique.
