PURPOSE: A multi-channel sound device is provided to replay stereo sound close to a real sound by replaying audio signals transmitted through a plurality of channels according to each channel. CONSTITUTION: A multi-channel sound device installed in a HMD(Head Mounted Display) is formed with a directly forward replay portion(130), a laterally forward relay portion(110,140), and a laterally backward relay portion(120,150). The directly forward replay portion(130) is used for replying a directly forward sound from a user's current position on the basis of the user's current position. The laterally forward replay portion(110,140) is used for replying a laterally forward sound from the user's current position on the basis of the user's current position. The laterally backward replay portion(130) is used for replying a laterally backward sound from the user's current position on the basis of the user's current position.
