VEHICLE APPROACH ALERT DEVICE
First Claim
1. A vehicle approach alert device comprising:
- a microcomputer having a memory that stores approach alert sound data to be output, and a signal generator that reads out the approach alert sound data from the memory and generates an approach alert sound voltage waveform signal indicative of a vehicle approach alert sound to be output based on the approach alert sound data, wherein;
the vehicle approach alert device alerts approach of a vehicle by outputting the vehicle approach alert sound from a sound outputting body according to the approach alert sound voltage waveform signal output from the microcomputer;
the microcomputer further includes;
an obtaining device that obtains a sound outputting body temperature as temperature of the sound outputting body; and
a sound pressure correcting device that corrects a voltage level of the approach alert sound voltage waveform signal generated by the signal generator to be larger as the sound outputting body temperature obtained by the obtaining device increases; and
the signal generator outputs a corrected approach alert sound voltage waveform signal of the sound pressure correcting device.
