PROBLEM TO BE SOLVED: To inform, in a sound reproduction device for informing approach of a vehicle, the approach of the vehicle in consideration of the degree of danger even in a sudden start or sudden acceleration which gives a high degree of danger.SOLUTION: A sound reproduction device has a sound source part 1, an amplifier 2 amplifying a signal outputted from the sound source part 1, and a speaker 3 reproducing the signal amplified by the amplifier 2, and between the sound source part 1 and the amplifier 2, is provided with a control part 6 which is inputted with a vehicle speed signal 4 and a torque demand signal 5 outputted according to the running state of a vehicle and controls the amplifier 2 interlinkingly with these signals. With this construction, sound volume of the speaker 3 can be temporarily increased by a certain amount in a sudden start or sudden acceleration of the vehicle. Accordingly, even in the case of giving a higher degree of danger such as in the sudden start or sudden acceleration of the vehicle, it becomes possible to more accurately inform pedestrians and so forth of approach of the running vehicle to attract attention, and very high safety can be ensured.

    【課題】車両の接近を知らせる音響再生装置において、危険度の高い急発進時や急加速時においても、車両の接近の危険度合いを考慮して知らせることを目的とする。【解決手段】音源部1と、音源部1から出力された信号を増幅する増幅器2と、増幅器2で増幅された信号を再生するスピーカ3とを有し、音源部1と増幅器2の間に、車両速度信号4と、車両の走行状態に応じて出力されるトルク要求信号5を入力し、これらの信号に連動して増幅器2を制御する制御部6を設けた構成により、車両の急発進時や急加速時にスピーカ3の音量を一時的に一定量大きくすることができるため、車両の急発進時や急加速時のような危険度がより高い場合でも、歩行者等に対して走行車両の接近を更に的確に知らせて注意喚起を図ることができるようになり、極めて高い安全性を確保することができる。【選択図】図1
