A sound-producing device for a vehicle includes sound-producing means, an opening provided in a vehicle body bottom part, and a duct connecting the sound-producing means to the opening, and it is possible, by amplifying the sound pressure of a sound generated by the sound-producing means through the duct and transmitting the sound to the outside of the vehicle via the opening of the vehicle body bottom part, to inform a pedestrian that the vehicle is approaching and alert them, and to reduce the sound pressure of the sound-producing means compared with a case in which there is no duct. Moreover, since an inlet and an outlet of the duct are offset from each other in a direction that intersects a vertical axis, it is possible to prevent water or small stones scattered by a tire from passing through the duct and to decrease the stiffness of the duct.
