The notification sound generating device comprises a loudspeaker (21), a control part (10), a resistor (22) and a correction part (S104). A speaker (21) for generating a notification sound around the vehicle; the control unit (10) outputs an audio signal for causing the speaker to generate a notification sound. The resistor (22) has a resistance value corresponding to a correction amount for correcting a sound pressure deviation of the speaker or a sound pressure value of the speaker. A correction unit (S104) corrects the audio signal on the basis of a physical quantity related to the resistance value of the resistor.
通知音产生装置包括扬声器(21)、控制部(10)、电阻器(22)以及校正部(S104);扬声器(21)在车辆的周围产生通知音;控制部(10)输出用于使扬声器产生通知音的音频信号;电阻器(22)具有电阻值,该电阻值与用于校正扬声器的声压偏差的校正量对应或与扬声器的声压值对应;校正部(S104)基于与电阻器的电阻值相关的物理量来校正音频信号。
