Abstract:
1. A vehicular annunciation device comprising: an electromagnetic alarm device being a single element, the electromagnetic alarm device including: a vehicle proximity notification device including a parametric speaker configured to cause an ultrasonic speaker to emit a notification ultrasonic wave to an outside of the vehicle for notifying a pedestrian of proximity of the vehicle, according to a traveling state of the vehicle and/or when a sensor detects a pedestrian, the notification ultrasonic wave being generated by implementing ultrasonic modulation on a proximity notification sound, which is different from an alarm sound, wherein the vehicle proximity notification device is configured to cause the ultrasonic speaker to emit an alarm ultrasonic wave when the alarm switch device is manipulated, the alarm ultrasonic wave being generated by implementing ultrasonic modulation on a second alarm sound including a fundamental tone at a second frequency, which is different from the first frequency.
