ELECTRONIC DEVICE WITH TIME UPDATE FUNCTION AND TIME UPDATE METHOD
First Claim
1. An electronic device with a time update function, comprising:
- a radio module configured for receiving signals broadcast from a broadcast station and outputting the received broadcast signals as audible audio signals;
an audio input port configured for receiving audio signals generated by the radio module;
a clock module configured for providing real time;
a storage module configured for storing an initial time; and
a processing module configured for determining a system time according to the stored initial time and the real time provided by the clock module, determining whether the audio signals received by the audio input port comprise current time information, and determining whether the system time is consistent with the current time information if the audio signals from the audio input port comprises current time information, the processing module further replacing the initial time with the current time information to adjust the system time if the system time is inconsistent with the current time information.

Abstract
An electronic device with time update function includes a radio module, a clock module, an audio input port, a storage module, and a processing module. The radio module receives and outputs audible signals from the broadcasts of a broadcasting station. The audio input port receives audible sound generated by the radio module, and the clock module provides a source of real time. The processing module determines whether the signals received by the audio input port include current time information, and if so whether the system time is consistent with the current time information. The processing module updates the stored initial time with the current time information and adjusts the system time as necessary. A time update method is also provided.
