1. An electronic device, comprising:
- a first processing unit;
a storage unit, configured to store at least one audio file, wherein the audio file comprises music data;
a first memory unit; and
a modulator-demodulator (modem), configured to perform audio processing for the electronic device during a phone call,wherein when the electronic device is used to play the audio file, the first processing unit reads the audio file from the storage unit, retrieves header information of the music data of the audio file, and writes the music data of the audio file into the first memory unit,wherein the modem accesses the music data of the audio file written by the first processing unit in the first memory unit, and performs audio decoding of the music data of the audio file based on the header information retrieved by the first processing unit,wherein the first processing unit enters a sleep state when the modem performs audio decoding.

10. An audio playing method for use in an electronic device, wherein the electronic device comprises a first processing unit, a storage unit, a first memory unit, and a modulator-demodulator (modem), and the storage unit stores at least one audio file, wherein the audio file comprises music data, the method comprising:
-
utilizing the first processing unit to read the music data of the audio file from the storage unit, retrieve header information of the music data of the audio file, and write the music data of the audio file into the first memory unit when the electronic device is used to play the audio file; and utilizing the modem to access the music data of the audio file written by the first processing unit in the first memory unit, and performing audio decoding of the music data of the audio file based on the header information retrieved by the first processing unit, wherein the first processing unit enters a sleep state when the modem performs audio decoding. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
