Abstract
A vehicle approach alert device includes: a microcomputer having a memory that stores approach alert sound data, and a signal generator that generates an approach alert sound voltage waveform signal based on the approach alert sound data. The vehicle approach alert device alerts approach of a vehicle by outputting a vehicle approach alert sound from a sound outputting body according to the approach alert sound voltage waveform signal. The microcomputer further includes: an obtaining device that obtains a sound outputting body temperature; and a sound pressure correcting device that corrects a voltage level of the approach alert sound voltage waveform signal to be larger as the sound outputting body temperature increases.
