AI Technical Summary

Technical Problem

The prior art is difficult to effectively retrieve lost electronic devices when the electronic device is in a shutdown state, especially when the device is in a shutdown state, the positioning and search function cannot be used.

Method used

An electronic device is designed, including an audio amplifier chip, a short-range communication module and a speaker. When the electronic device is in a shutdown state, ringing commands are received through the short-range communication module. The audio amplifier chip directly responds and outputs audio through the speaker, reducing the power consumption of SOC and Codec.

Benefits of technology

It effectively reduces the power consumption of electronic devices during the retrieval process, extends the battery life of the device in the shutdown state, and increases the probability that the lost device will be successfully retrieved.
