PURPOSE:To reproduce a desired stereo sound field by reproducing a stereo input signal and a reverberation signal in a state approaching to an anechoic chamber in an audible sense by applying a signal processing so as to offset unrequired reflecting sound in a vehicle room on the input signal. CONSTITUTION:Reproducing sound by speakers for sterophonic reproduction to which the input signal are supplied via signal processing means (3-6) arrive at an audible position in the state where the reflecting sound in a small space in a sealed vehicle room is offset. Also, the reproducing sound by the speakers 9 and 10 for attaching reverberation to which the input signal is supplied via the signal processing means (3-6) arrive at the audible position as reverberation sound delayed by the reproducing sound by the speakers 7 and 8 for stereophonic reproduction. In such a way, it is possible to obtain the stereo sound field with superior reality, and to improve a spatial sense by a surrounding function without generating incongruity. |
