Abstract

PURPOSE: To make possible the good transmission of sounds of sound multiplex motion pictures by equipment of simple constitution by providing a loop antenna or the like of crossed form near the audience position and transmitting plural sounds by using the carriers of different frequencies.
CONSTITUTION: An electromagnetic radiator 7 is constituted by a loop antenna 8 which is connected to a matching circuit 6 and assumes approximately 8-form as the two rings enclosing the seats 9... of the audiences cross. This radiator is buried on or under the floor. With this constitution, the RP signal multiplexed with plural sounds using the carriers of different frequencies is transmitted to the audiences within the two rings formed by the antenna 8 and in the region outside the loop of the antenna 8, the radiation electromagnetic energies from both rings negate with each other and the electromagnetic field level attenuates sharply. By the equipment of the simple constitution, the multiple sounds are well transmitted. The similar results are also obtained even by using a parallel line form antenna 8' terminating at a terminal impedance element 10.
