Abstract
A stereophonic apparatus uses three speakers respectively installed toward a front of a vehicle on both shoulders of a seat back of a driver's seat and toward a back of the vehicle on an exact center in front of a driver. This configuration provides more effectively exerted positioning effects for a virtual sound source realized by using the three speakers, especially for the effects in a frontward field of sound.
