Abstract

Die Erfindung betrifft eine Kopfhörervorführeinrich­ tung, bei der ein Kopfhörer hängend an einem Anschluß­ stück befestigt ist, das unter entsprechendem Leiterabgriff mit einer Stromschiene verriegelbar und wieder von dieser lösbar ist. Die Stromschiene ist an einer Decken - bzw. Seitenwand eines Raumes, Standes od.dgl. befestigbar und an ein dem Kopfhörer zugeordnetem Vorführgerät an­ geschlossen. Die Einrichtung ist platzsparend und ermög­ licht insbesondere eine einfache Variierung der Zahl und Position der Kopfhörer.
