Abstract

L'invention concerne un appareil à semi-conducteurs pour la reproduction de signaux acoustiques. Dans cet appareil qui comporte une partie réception AU et une partie de reproduction WT ainsi qu'un microphone M, un amplificateur V1, un filtre TP, un amplificateur V2 et un haut-parleur L, le microphone M recevant le signal acoustique est raccordé par l'amplificateur V1 à un convertisseur analogique/numérique A/D produisant des impulsions électriques discrètes contenant la formation du signal acoustique et les transmettant par l'intermédiaire d'une mémoire d'inscription/lecture S à un convertisseur numérique/analogique D/A qui fournit au microphone M un signal électrique analogue au signal acoustique originel. Application notamment aux magnétophones à semi-conducteurs.
