PROBLEM TO BE SOLVED: To provide a sound effect sounding device capable of transmitting information of direction.SOLUTION: In a sound effect sounding device 1, a control unit 10 transmits a piece of information, to be transmitted to a vehicle crew, by sound effect from a plurality of speakers SP, outputs a frequency signal with the same timing for the plurality of speakers SP, and outputs a basic sound effect therefrom. Thereafter, the control unit outputs sound effects, where at least one of the sound pressure and sound output time zone is different, from a plurality of speakers SP, by controlling the frequency signals to the plurality of speakers SP, thus imparting a directivity, for directing the consciousness to any one of the plurality of speakers SP, to the piece of information.SELECTED DRAWING: Figure 1 |
