PROBLEM TO BE SOLVED: To provide a sound output system which represents a result of authentication of a person passing a gate by using sound effects.SOLUTION: A sound output system comprises: a gate (1) having a reader (1a) which acquires identification information when a communication medium that can transmit the identification information approaches the reader (1a); a control device (2) having a transmission unit (25) which transmits a sound source signal when the identification information acquired by the reader (1a) is authenticated; a directional speaker (3) which is electrically connected with the control device (2) and outputs the sound source signal; and a non-directional speaker (4) which outputs the sound source signal transmitted from the transmission unit (25). |
