A notification device (1) includes a sweep signal generator (3) that generates a sweep signal by changing the frequency of a predetermined wave at a constant speed in a frequency band which allows exciters (EX1, EX2, EX3, EX4) to generate a vibration, a sweep signal divider (4) that divides the sweep signal into a higher-band sweep signal in a higher-frequency band including an overlap frequency band and a lower-band sweep signal in a lower-frequency band including the overlap frequency band, a signal output determination unit (2) that determines from which exciters the higher-band sweep signal and lower-band sweep signal should be outputted, and an output signal adjuster (9) that makes an adjustment for outputting the higher-band sweep signal and lower-band sweep signal from the exciters determined.
