PURPOSE:To create an AV space suited to needs by selecting optionally the output of a reproducer and the output of a sound field creating device as an output from a 2nd speaker. CONSTITUTION:A signal S1 inputted to an input terminal 1 is branched into two by a branching means 7, inputted to a branching means 8 and a sound field creating device 4, and an output signal S3 of the sound field creating device 4 is inputted to a 1st input terminal of a selection means 9. The signal inputted to the branching means 8 is divided into two, one output is amplified as it is at an amplifier 2 and subjected to electroacoustic conversion by a speaker 3, from which a sound wave M1 is outputted. The other output is inputted to a 2nd input terminal of a selection means 9 and the selected signal S5 is amplified by an amplifier 5 and subjected to electroacoustic conversion by a speaker 6, from which a sound wave M2 is sounded. Thus, the AV space in matching with the needs is created. |
