PURPOSE:To expand a sound field in 3-D and to facilitate a reproducing having a sound field feeling and a feeling of staying at a live performance by converting plural kinds of surrounding signals into sound waves and emitting them in space. CONSTITUTION:Surrounding signal processing means 1 and 2 applying a surrounding processing to stereo/audio signals R and L of the right and left channels to be reproduced and outputs at least two kinds of surrounding signals for each of the stereo/audio signals of the respective channels to an electric/ acoustic conversion means. Right hand speakers 7 and 8 of the electric/acoustic conversion means is supplied with the surrounding signal on the side of the right channel out of the surrounding signals, and converts at least two kinds of surrounding signals into the sound waves and emits them in space. Right hand speakers 9 and 10 is supplied with the surrounding signal on the side of the left channel out of the surrounding signals, and converts at least two kinds of surrounding signals into the sound waves and emits them in space. |
