Stereoreproduction system with common reverberation

Claim 1

STEREOPHONIC SOUND REPRODUCING APPARATUS FOR UTILIZING RIGHT AND LEFT STEREO SIGNAL COMPONENTS, SAID APPARATUS INCLUDING IN COMBINATION, MEANS FOR DERIVING FIRST AND SECOND STEREOPHONIC SIGNAL COMPONENTS, FIRST AND SECOND AMPLIFIER CHANNELS RESPECTIVELY FOR THE FIRST AND SECOND SIGNALS AND INCLUDING ASSOCIATED LOUDSPEAKERS FOR SEPARATELY REPRODUCING THE STEREO SIGNAL COMPONENTS, A FURTHER AMPLIFIER CHANNEL INCLUDING A LOUDSPEAKER, FILTER MEANS FOR DERIVING LOW FREQUENCY SIGNAL COMPONENTS FROM SAID FIRST AND SECOND AMPLIFIER CHANNELS AND FOR COUPLING SUCH LOW FREQUENCY SIGNAL COMPONENTS TO SAID FURTHER AMPLIFIER CHANNEL, A REVEBERATION DEVICE PRODUCING A DELAYED SIGNAL OF DECAYING AMPLITUDE COUPLED FROM SAID RIGHT AND LEFT AMPLIFIER CHANNELS TO SAID FURTHER AMPLIFIER CHANNEL FOR AMPLIFYING THE DELAYED SIGNAL OF DECAYING AMPLITUDE, SO THAT SAID FURTHER AMPLIFIER CHANNEL MAY REPRODUCE BOTH THE LOW FREQUENCY SIGNAL COMPONENTS AND REVERBERATED SIGNAL COMPONENTS FOR A STEREOPHONIC AND REVERBERATION EFFECT IN THE OVERALL SOUND PATTERN PRODUCED BY SAID LOUDSPEAKERS.
