Abstract
A notification device () includes a sweep signal generator () that generates a sweep signal by changing the frequency of a predetermined wave at a constant speed in a frequency band which allows exciters (EX, EX, EX, EX) to generate a vibration, a sweep signal divider () 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 () that determines from which exciters the higher-band sweep signal and lower-band sweep signal should be outputted, and an output signal adjuster () that makes an adjustment for outputting the higher-band sweep signal and lower-band sweep signal from the exciters determined.
