Patent ID: 8823501

Claim:
A vehicle presence notification apparatus that generates a notice sound in an area outside of a vehicle when a driving condition to report a presence of the vehicle is satisfied, the vehicle presence notification apparatus comprising: an audible-sound generation piezoelectric speaker that provides a primary resonance portion existing in an audible frequency band, wherein: when vehicular information satisfies a predetermined first condition, the vehicular information being a travel state of the vehicle, the audible-sound generation piezoelectric speaker is caused to perform an audible notice sound direct generation to generate directly a notice sound that is audible; when the vehicular information satisfies a predetermined second condition, the audible-sound generation piezoelectric speaker is caused to perform an ultrasonic emission to emit an ultrasonic wave that is prepared by applying an ultrasonic modulation to a signal to form a notice sound; and when a vehicle speed of the vehicle is less than a predetermined value, the vehicular information satisfies the predetermined first condition, whereas when the vehicle speed of the vehicle is equal to or greater than the predetermined value, the vehicular information satisfies the predetermined second condition.
