The invention discloses an analog sound generating device and an analog sound generating method. The analog sound generating method comprises the following steps: a control unit (110) determines the width of a road on which a vehicle (CR) runs according to the current position of the vehicle (CR), by reference to road width information in map information (MPD) stored in a storage unit (120); the control unit (110) determines a reaching range within which analog sound is output outside the vehicle according to the determined road width; then, the control unit (110) determines the set volume of the analog sound output from a left loudspeaker and a right loudspeaker of an analog sound generating unit (130) according to the determined reaching range; as a result, the analog sound with volume corresponding to the set volume of the analog sound output from the left loudspeaker and the right loudspeaker of the analog sound generating unit (130) is output outside the vehicle. Therefore, when the possibility that a report object exists in the surrounding correspondingly changing along with the width of the road on which the vehicle runs is taken into consideration, the volume of the analog sound can be properly controlled.
