PROBLEM TO BE SOLVED: To efficiently spread and reflect a reflected sound from a sounding means such as a speaker. SOLUTION: The sound reflection system includes: a sound reflector r for reflecting a sound flux, and an array speaker ASP for emitting the sound flux from a sound flux emission face P to the sound reflector r, a reflection face rs of the sound reflector r is formed to be a smoothly projected shape and is projected toward a direction wherein the sound flux is emitted. Through the configuration above, the sound flux can efficiently be spread in front and rear directions of the sound reflector r. COPYRIGHT: (C)2006,JPO&NCIPI
