Classification: CPC G | IPC G

Claim 9:
10. A vibration driving method, adapted to an electronic device, comprising:
outputting an audio signal to an audio player according to an application program;
executing an audio analysis module to analyze the audio signal;
determining, by the audio analysis module, whether the audio signal has a loudness with an audio frequency lower than a default frequency threshold according to an audio frequency distribution of the audio signal; and
outputting, by the audio analysis module, a vibration drive signal according to the loudness of the audio signal, when the audio analysis module determines that the audio signal has the loudness with an audio frequency lower than the default frequency threshold,
wherein the electronic device comprises a vibration module receiving the vibration drive signal, wherein a vibration intensity of the vibration module is positively correlated with the loudness,
wherein the vibration module comprises a first vibrator and a second vibrator, and the step of outputting, by the audio analysis module, the vibration drive signal according to the loudness of the audio signal comprises:
driving, by the audio analysis module, at least one of the first vibrator and the second vibrator according to the audio signal,
wherein the step of driving, by the audio analysis module, at least one of the first vibrator and the second vibrator according to the audio signal comprises:
outputting, by the audio analysis module, a first vibration drive signal to the first vibrator according to the first loudness, when the audio analysis module determines that the audio signal comprises a left channel signal and that 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
outputting, by the audio analysis module, a second vibration drive signal to the second vibrator according to the second loudness, when the audio analysis module determines that the audio signal comprises a right channel signal and that 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.
