Abstract:
A portable device and a method for entering a power-saving mode are provided. Audio stream is generated by an audio player, and an audio signal is generated according to the audio stream and then transmitted to an earphone via a cable by a digital-analog converter. At least one electrical characteristic on the cable is sensed to generate at least one sensing signal. The at least one sensing signal is sampled to generate at least one data signal. Whether the earphone is inserted into an ear canal is determined according to the at least one data signal. For determining whether the earphone is inserted into the ear canal, an impedance frequency response related to the earphone is obtained according to the at least one data signal, and whether the earphone is inserted into the ear canal is determined according to a characteristic of peaks of the impedance frequency response.

Claim (Index 9):
The portable device as claimed in  claim 8 , wherein the controller comprises:\n a frequency response detector transferring both of the current data signal and the voltage data signal from a time domain to a frequency domain and obtaining the impedance frequency response related to the earphone according to the current data signal and the voltage data signal which are in the frequency domain; a decision unit comparing a number of peaks of the impedance frequency response with a number of leaks of a reference impedance frequency response and determining that the earphone is not inserted into the ear canal of the user when the number of peaks of the impedance frequency response is different from the number of leaks of the reference impedance frequency response.
