Abstract: A vehicle approach notification unit produces a notification sound outside a vehicle when a predetermined driving condition is met to notify an approach of the vehicle. The vehicle approach notification unit has a cavity portion and a small speaker. The cavity portion is disposed to a component of the vehicle and has a sound space therein. The small speaker directly produces the notification sound including an audible frequency. The small speaker is disposed at the cavity portion and emits the notification sound into the sound space of the cavity portion. The cavity portion has a diaphragm or a sound outlet that emits the notification sound from the sound space of the cavity portion outside the vehicle.

Abstract: A vehicle approach notification unit is disposed in a vehicle for producing a notification sound. The vehicle approach notification unit has a speaker and a thin film. The speaker is disposed to a sound tube of a vehicle horn of the vehicle. The vehicle horn produces a resonant warning sound with a resonant frequency. The thin film partitions a space between the speaker and the sound tube. The speaker emits the notification sound into the sound tube so that the notification sound is emitted outside of the vehicle via the sound tube. The thin film restricts a sound wave having the resonant frequency from being transmitted, and allows a sound wave having a frequency producing the notification sound to be transmitted.

Abstract: A vehicle approach notification unit is mounted to a sound tube of an electromagnetic warning device producing a warning sound, and includes a dynamic speaker that produces a notification sound notifying a presence of a vehicle. The dynamic speaker is mounted to the sound tube and outputs the notification sound through the sound tube to outside of the vehicle. The sound tube has a warning sound outlet at an end of the sound tube and a through hole at a position different from the warning sound outlet.

Abstract: A vehicle approach notification unit disposed in a vehicle for producing a notification sound outside of the vehicle includes a small speaker producing the notification sound having an audible frequency. The small speaker is disposed on a sound tube of a horn of the vehicle, the horn producing a warning sound. The small speaker emits the notification sound into the sound tube, such that the notification sound is emitted from the vehicle via the sound tube. The small speaker is located in a midstream in a sound passage of the sound tube.

Abstract: A vehicle presence notification apparatus notifying a presence of a vehicle includes a directivity speaker and a directivity controller. The directivity speaker generates a false engine sound out of the vehicle. The directivity controller controlling a directivity of the false engine sound based on a speed of the vehicle. The directivity controller controls a ratio of a high-pitched frequency component to a low-pitched frequency component in the false engine sound based on the speed of the vehicle.
