To facilitate correction of sound pressure of notification sound to be output from a speaker.SOLUTION: A notification sound generation device includes: a speaker 21 for generating notification sound in the periphery of a vehicle; a control section 10 for outputting a sound signal to allow the speaker 21 to generate the notification sound; and a resistance 22 having a resistance value corresponding to a correction amount to compensate for sound pressure variations of the speaker 21 or a resistance value corresponding to a sound pressure value of the speaker. The sound signal is corrected based on a physical quantity correlated with the resistance value of the resistance 22.SELECTED DRAWING: Figure 1

    【課題】スピーカから出力される報知音の音圧の補正を容易に行えるようにする。【解決手段】車両の周囲に報知音を発生させるスピーカ21と、スピーカ21に報知音を発生させるための音声信号を出力する制御部10と、を備える。さらに、スピーカ21の音圧ばらつきを補正するための補正量に対応する抵抗値またはスピーカの音圧値に対応する抵抗値を有する抵抗22を備える。そして、抵抗22の抵抗値と相関する物理量に基づいて音声信号を補正する。【選択図】図1
