ABSTRACT:
The invention relates to a sound distribution system for a drive-in theatre. The system comprises means for converting the sound track of a film into an audio information signal and means for transmitting the signal to at least one sound reproducing apparatus. The sound reproducing apparatus is for use with a magnetic playback apparatus having at least one playback head and a cassette or cartridge receiving aperture. The sound reproducing apparatus includes a transducer having at least one transfer head and alignment means for receiving the transfer head and for maintaining the head in a spatial position relative to the alignment means, whereby when the sound reproducing apparatus is inserted into the receiving aperture the transfer head is aligned opposite a respective playback head of the playback apparatus so that the signals may be reproduced as sound by the playback apparatus.
