Description

Bei der Betrachtung eines Fernsehbildes befindet ;ich der Beschauer im allgemeinen in geringem Ab- :tail(l voni Empfänger.

Auch ist es in Einzelfällen denkbar, (laß sie zur optischen Korrektur herangezogen wird. Der Antrieb und die Halterung der Membran müssen dabei, wie an sich bekannt, am Rand stattfinden. I )ic Zrichming zeigt beispielsweise schematisch ciiie Ausführungsfarin der Erfindung itn Schnitt. In dieser Zeichnung ist i (las Gehäuse eines Fernsehempfängers mit der Röhre z. Vor dein Schirm 3 dieser Röhre ist die aus durchsichtigem Kunststoff angefertigte Membran 4 angeordnet, die am Rand angetrieben und gehaltert wird. Zwei der Antriebsstellen 3 und 0 sind dargestellt. An dazwischenliegenden nicht gezeichneten Stellen ist sie elastisch gehaltert. Der Pfeil zeigt clie l',lickvorrichtung des Heschauers und Ztiliörei-s. When viewing a television picture is located ; I the spectator in general in a slight : tail (l voni recipient. The consequence of this is that the (") rtliclie (` consistency of picture and sound hei \ - (# rwenduug of a laterally arranged sound sl @ recl @ ers is unsuitable.
