Abstract
Provided is a notification device and notification method that reduce the output and power consumption of an amplifier or the like and allow a user to sufficiently feel the presence or absence of notification through vibration. A notification device () includes a sweep signal generator () configured to generate a detection sweep signal by continuously changing the frequency in a frequency band in which a speaker () can cause a user to feel a signal in the form of vibration, a vibration detector () configured to detect vibration outputted from the speaker (), and a sound measurement unit () configured to detect, as a sweep frequency band, a frequency band in which vibration indicates signal levels equal to or higher than a threshold. The sweep signal generator () generates a resonance sweep signal by changing the frequency in the sweep frequency band and causes the speaker () to generate vibration.
