Abstract
Sounds of two spiral horns of a treble horn and a bass horn are pronounced in a unitized form. A warning sound generator comprises a power supply circuit (1) for receiving the output of a battery (30) to output drive current, a sound output circuit section (4) for receiving the drive current to output a composite sound of the treble horn and bass horn of the previously stored spiral horns, an amplifier circuit section (5) for amplifying the composite sound outputted from the sound output circuit section (4) after receiving the drive current, and a speaker (9) for pronouncing the sound amplified by the amplifier circuit section (5) to the outside.
