Classification: CPC G | IPC G

Claim 16:
17. A vibration driving method, adapted to an electronic device, comprising:
outputting an audio signal to an audio player according to an application program, wherein the audio signal comprises a left channel signal and a right channel signal;
executing an audio analysis module to analyze the left channel signal and the right channel signal;
determining, by the audio analysis module, whether the left channel signal has a first loudness with a first audio frequency lower than the default frequency threshold according to a first audio frequency distribution of the left channel signal, and whether the right channel signal has a second loudness with a second audio frequency lower than the default frequency threshold according to a second audio frequency distribution of the right channel signal;
outputting, by the audio analysis module, a first vibration drive signal according to the first loudness, when the audio analysis module determines that the audio signal comprises the left channel signal having the first loudness with the first audio frequency lower than the default frequency threshold; and
outputting, by the audio analysis module, a second vibration drive signal according to the second loudness, when the audio analysis module determines that the audio signal comprises a right channel signal having a second loudness with a second audio frequency lower than the default frequency threshold,
wherein the audio analysis module further defines whether an external device is located on a left or right side of the electronic device according to an external device setting, so as to determine whether to output the first vibration drive signal or the second vibration drive signal to a third vibrator disposed in the external device.
