To provide a vehicle approach notifying system capable of reducing unpleasantness to passengers while effectively outputting a notification sound to the outside of a vehicle.SOLUTION: A vehicle approach notification system 100 for notifying approach of a vehicle includes: a first speaker 51 and a second speaker 52 provided in a speaker case 53 included in the vehicle; a sound source 20 that outputs sound signals which are respectively input to the first speaker 51 and the second speaker 52 and correspond to a sound notifying the approach of the vehicle; and a phase controller 30 that controls a phase of at least one sound signal out of the sound signal input to the first speaker 51 and the sound signal input to the second speaker 52 so that sound pressure at left and right of the vehicle caused by the sound output from the first speaker 51 and the second speaker 52 is higher than sound pressure along a longitudinal axis of the vehicle.SELECTED DRAWING: Figure 3
【課題】車外に対して効果的に報知音を出力しつつ、搭乗者へ与える不快感を低減できる車両近接報知システムを提供する。【解決手段】車両の接近を報知するための車両近接報知システム100は、車両に搭載された1つのスピーカ筺体53内に設けられた第1スピーカ51および第2スピーカ52と、車両の接近を報知する音に対応する音信号であって、第1スピーカ51および第2スピーカ52に入力される音信号を出力する音源20と、第1スピーカ51および第2スピーカ52から出力される音の車両の左方および右方の音圧が車両の前後方向軸上の音圧よりも高くなるように、第1スピーカ51に入力される音信号および第2スピーカ52に入力される音信号のうちの少なくとも一方の音信号の位相を制御する位相制御部30と、を備える。【選択図】図3
