PROBLEM TO BE SOLVED: To provide an earphone interface circuit with small space occupancy in a printed-circuit substrate and to provide an audio player using the same.SOLUTION: The earphone interface circuit includes a first earphone jack, a second earphone jack, a first electrolytic capacitor, and a second electrolytic capacitor. The first earphone jack includes a first interference prevention unit that prevents interference between audio signals of a right channel and a left channel transmitted to the first earphone jack. The second earphone jack includes a second interference prevention unit that prevents interference between audio signals of a right channel and a left channel transmitted to the second earphone jack. |
