Wearable device, method, and computer-readable storage medium for providing audio corresponding to emergency siren

Abstract

A wearable device includes memory, including one or more storage mediums, storing instructions, a speaker, and at least one processor including processing circuitry, and the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to, based on an emergency state of a user, to provide audio corresponding to an emergency siren, output a first audio signal, through the speaker, on a first frequency range with first sound pressure and after outputting the first audio signal, output a second audio signal through the speaker on a second frequency range having audible sensitivity higher than audible sensitivity in the first frequency range with second sound pressure greater than the first sound pressure, wherein a resonant frequency of the speaker is changed from the first resonant frequency to the second resonant frequency lower than the first resonant frequency in accordance with outputting the first audio signal.
