Document Type and Number:
Japanese Patent JP6511353
Kind Code:
B2
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 (1) includes a sweep signal generator (4) configured to generate a detection sweep signal by continuously changing the frequency in a frequency band in which a speaker (6) can cause a user to feel a signal in the form of vibration, a vibration detector (7) configured to detect vibration outputted from the speaker (6), and a sound measurement unit (8) 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 (4) generates a resonance sweep signal by changing the frequency in the sweep frequency band and causes the speaker (6) to generate vibration.
