Abstract
A sound-directed-outside-vehicle emitting device includes a storage unit 2-A for storing criteria by each of which to determine whether or not a running zone is a high-risk zone, each of the criteria describing a status of the vehicle, and a navigation device 1-A for acquiring information showing a status of the vehicle. The sound-directed-outside-vehicle emitting device compares the information acquired by the navigation device 1-A with the criteria stored in the storage unit 2-A to determine whether the above-mentioned vehicle is running through a high-risk zone, and does not stop the output of a warning sound when determining that the vehicle is running through a high-risk zone even if a switch 4 for commanding a stop of the output of the warning sound is operated.
