Referring to fig. 1, fig. 1 is a diagram illustrating a method for authorizing and activating a device by sound waves according to an embodiment of the present invention, which may be applied to, but is not limited to, a device or software that requires authorized activation to use a related function or right. The method comprises the following steps:
s101, the hardware information of the equipment is coded into a first audio signal through the equipment to be authorized.
Specifically, the device to be activated to be authorized may be any device or system that requires an authorized activation to have an authority or a related function.
S102, circularly playing a first sound wave signal corresponding to the first audio signal through a loudspeaker of the to-be-authorized activated device, and simultaneously starting a microphone of the to-be-authorized activated device to record.
Specifically, the to-be-authorized activation device needs to be provided with a loudspeaker and a microphone and has the functions of playing sound and recording.
