To provide an acoustic vehicle alerting system that can generate alert sound that allows a pedestrian to easily distinguish whether a vehicle is moving toward the pedestrian or passing around the pedestrian.SOLUTION: An acoustic vehicle alerting system 10 includes: a diaphragm 210 disposed in an internal space and configured to generate sound; and a sound emitter 200 configured to output alert sound to the outside of a vehicle. A control device 100 controls the sound emitter 200. The sound emitter 200 includes: a first sound guide pipe 221 oriented to the front face of the vehicle; and a second sound guide pipe 222 and a third sound guide pipe 223 that are oriented to directions different from that of the first sound guide pipe 221. The first sound guide pipe 221, the second sound guide pipe 222, and the third sound guide pipe 223 resonate the sound emitted from the diaphragm 210 and thus amplitude the sound with frequency according to the pipeline length. The pipeline length of the first sound guide pipe 221 is different from the pipeline lengths of the second sound guide pipe 222 and the third sound guide pipe 223.SELECTED DRAWING: Figure 1

    【課題】車両が歩行者に向かって進行しているか、車両が歩行者の周囲を通過するか、歩行者が判別しやすい通報音を発生することができる車両接近通報装置を提供する。【解決手段】車両接近通報装置10は、音を発生する振動板210が内部の空間に配置されるとともに、車両の外側に向けて通報音を出力する発音器200を備える。制御装置100は、発音器200を制御する。発音器200は、車両の正面前方に向けられている第1導音管221と、第1導音管221とは異なる方向に向けられている第2導音管222及び第3導音管223とを備える。第1導音管221、第2導音管222及び第3導音管223は、振動板210から発せられる音を共鳴させることで、管路長に応じた周波数の音を増幅する構造を備える。第1導音管221の管路長と、第2導音管222及び第3導音管223の管路長は異なる。【選択図】図1
