1. An acoustic reproduction system, comprising:
a sound producing device configured to emit a directional sound;
a sound reflector positioned between a viewer and a viewing target by the viewer and having a plurality of sound reflecting surfaces that reflects the directional sound emitted by the sound producing device, wherein
the plurality of sound reflecting surfaces have mutually different inclination directions; and
the sound producing device is further configured to emit the directional sound from a ceiling side to a first sound reflecting surface of the plurality of sound reflecting surfaces and from a floor side to a second sound reflecting surface of the plurality of sound reflecting surfaces.
