Abstract
A vehicle approach alert device includes: a first output sound voltage waveform signal generator having a first output sound generator that generates a first signal corresponding to output sound data read out from a memory device, and a first sound volume variable device that controls a voltage level of the first signal; a second output sound voltage waveform signal generator having a second output sound generator that generates a second signal corresponding to the output sound data read out from the memory device, and a second sound volume variable device that controls a voltage level of the second signal; a mixer circuit that mixes the first signal and the second signal; and an amplifier that outputs a vehicle approach alert sound with flowing current, which corresponds to a voltage of a mixed signal, through a sound output body.
