PURPOSE: To move a sound image continuously in an optional direction in real time by detecting the direction of sound image movement and obtaining an output of SP for each reproduction so as to move the sound image at a sound field variable device.
CONSTITUTION: The input device consists of a variable resistor group 1, a resistance value conversion means 2, an input device 3, a signal input means 4, a sound field variable device 5, an amplifier 6, and a speaker 7. Then the variable resistor group 1 and the resistance conversion means 2 calculate the constant of the sound image moving direction set to the sound field variable device and related to the function defined definitely to each resistance. Thus, the sound image is moved in an optional space position continuously in real time.
