Smart glasses, method and device for automatic volume control, and smart glasses system

A device for automatic volume control, comprising:

• a processor;
• a non-transitory computer readable storage medium coupled to the processor;
• and
• one or more computer programs stored on the non-transitory computer readable storage medium and executable on the processor;
• wherein, the one or more computer programs comprise:
• instructions for obtaining an audio signal picked up by one or more microphones provided on a glasses body of smart glasses;
• instructions for determining whether the audio signal is a noise signal;
• instructions for, in response to the audio signal being the noise signal, calculating a noise level of the noise signal;
• and
• instructions for adjusting an output volume of one or more speakers provided on the glasses body of the smart glasses to an output volume corresponding to the noise level of the noise signal according to a preset corresponding relationship between noise levels and output volumes of the one or more speakers.

A smart glasses system, comprising:

• smart glasses, a smart terminal and a cloud system;
• wherein the smart glasses are connected to the smart terminal through a wireless network, and the smart terminal is connected to the cloud system through a wireless network;
• the smart glasses are configured for:
• obtaining, through one or more microphones provided on a glasses body of the smart glasses, an audio signal;
• determining whether the audio signal is a noise signal;
• and
• in response to the audio signal being the noise signal, calculating a noise level of the noise signal, and adjusting an output volume of one or more speakers provided on the glasses body of the smart glasses to an output volume corresponding to the noise level of the noise signal according to a preset corresponding relationship between noise levels and output volumes of the one or more speakers;
• the smart glasses are further configured for sending the adjusted output volume to the smart terminal;
• and
• the smart terminal is configured for synchronously updating an output volume of a speaker of the smart terminal to the adjusted output volume.
