用ステレオ再生装置。 A left channel speaker 1, a right channel speaker 2, a center speaker 3, and low frequency cutoff filters 4 and 5 connected to the input circuits of the left and right channels, respectively; the attenuators 6 and 7 and the attenuator 6
.
The left channel speaker 1 is driven by the sum signal of the full band signal of the left channel and the right channel signal whose band and amplitude are limited and whose phase is inverted, and the right channel speaker 2 is driven by the sum signal of the full band signal of the left channel. The central speaker 3 is driven by the sum signal of the band signal and the left channel signal whose band and amplitude are limited and whose phase is inverted. An in-vehicle stereo playback device characterized in that it is driven by
