Vehicle Approach Alert Device

摘要

A vehicle approach alert device includes: a memory memorizing a warning sound source data for emitting a warning sound from an external sound emitting unit and a canceling sound source data for emitting a canceling sound from an internal sound emitting unit. The canceling sound cancels the warning sound transmitted from the external sound emitting unit to inside of the vehicle. The vehicle approach alert device further includes: a control part configured to read the warning sound source data from the memory to cause the external sound emitting unit to emit the warning sound based on the warning sound source data, and to read the canceling sound source data from the memory to cause the internal sound emitting unit to emit the canceling sound based on the canceling sound source data to be synchronized with the warning sound.

1. A vehicle approach alert device that warns an approach of a vehicle by emitting a warning sound from an external sound emitting unit toward an outside of the vehicle, the vehicle approach alert device comprising:
an internal sound emitting unit emitting sound toward an inside of the vehicle; a memory memorizing a warning sound source data for emitting the warning sound and a canceling sound source data for emitting a canceling sound that cancels the warning sound transmitted from the external sound emitting unit to an inside of the vehicle; and a control part configured to
read the warning sound source data from the memory to cause the external sound emitting unit to emit the warning sound based on the warning sound source data, andread the canceling sound source data from the memory to cause the internal sound emitting unit to emit the canceling sound based on the canceling sound source data to be synchronized with the warning sound.
