Abstract

Disclosed is a melody alarm device for a road facility to prevent drowsy driving. The melody alarm device for a road facility to prevent drowsy driving, according to the present invention, comprises: a sound source generation tube having a plurality of holes formed through the tubular main body thereof and arranged at predetermined intervals; and an air suction guide member guiding a flow of ambient air into an inlet at the tip end of the tubular main body. According to this configuration, the present invention can provide the practical melody alarm device for a road facility to prevent drowsy driving, the device having a wind instrument shape in which an induced wind generated by a vehicle travelling on a road is introduced into the inlet of the tubular main body by the air suction guide member and discharged through the holes and a discharge hole at the rear end of the main body to generate a melody sound source and propagate the same to the surroundings, thereby significantly enhancing productivity and economic feasibility by means of a product configuration of a prop form and considerably enhancing availability and efficiency of a constructed facility and a degree of freedom for a constructed facility site.
