Abstract

PURPOSE:To locate the sound images to any direction, by locating >=3 pieces of speakers at points with equal distance from a listener and varying the sound volume of the respective speakers. CONSTITUTION:Speakers 5, 5', 6, 6' are located at equal distance from a listener 4. a signal applied to a terminal 15 is divided into four, the level is adjusted at attenuators 11-14, amplified at amplifiers 7-10, and applied to the speakers 5, 5', 6, 6'. Thus, by varying the level ratio of the attenuators 11-14, the sound image 16 can be located at points within a distance A from the speakers in front of the listener 4.
