Abstract
A method for waking up a smart device includes receiving sound information; determining whether the sound information includes a multi-frequency tone; and when the sound information includes the multi-frequency tone, waking up a preset function of the smart device based on the multi-frequency tone. A device for waking up a smart device as well as a smart device incorporating the device includes processing elements for performing the method. A non-transitory computer-readable storage medium stores computer instructions to cause processing elements to perform the method for waking up a smart device.
