Abstract
Provided is an area reproduction system including a reproduction unit including a speaker array, a processing unit that processes a reproduction sound to be output from each of a plurality of speakers included the speaker array, based on a control line including a reproduction line that strengthens a sound wave radiated from the speaker array and a non-reproduction line that weakens the sound wave, so that an audio beam of a predetermined sound pressure or more is radiated only to the reproduction line, the control line being substantially parallel with the speaker array and being set in a position separated from the speaker array, and a directional angle control unit that adjusts a phase of the reproduction sound so that a radiating direction of the audio beam is deflected by a specified angle, in which each of the plurality of speakers outputs the processed and adjusted reproduction sound.
