Abstract

PURPOSE:To obtain the reverberation thereby to improve the attended feeling by mixing and delaying right and left signals so that they may be fed to a speaker other than right and left speakers. CONSTITUTION:The left and right signals at terminals 1 and 2 are fed through a pre-amplifier 3, a power amplifier 4 and cross-over net works 6 and 10 to left signal speakers 7 and 8 and left signal speakers 11 and 12. On the other hand, the output of the amplifier 3 is mixed and delayed at 13 so that it is fed through an amplifier 14 and a filter 16 to left and right mixed signal speakers 17 and 18. As a result, it is possible to hear in a car compartment the stereo-phonic signals which have their indirect sounds interpolated.
