Abstract

An apparatus for wirelessly transmitting the sound signal from a television receiver to a separate player device, specifically a set or equipment of headphones, by means of an auxiliary signal, characterized in that in the television receiver the sound signal is, for example, modulated in amplitude in a carrier wave of a higher frequency, is transmitted as ultrasonic sound, and is demodulated and reproduced in the reproductive device with the help of an ultrasonic receiver.
