A direct current blocking capacitor built-in earphone and a mobile communication terminal using the same are provided to increase a mounting efficiency of components by reducing an area of a circuit board. A mobile communication terminal(300) includes an audio signal generator(310), an audio amplifier(320) and an earphone terminal(330). The audio signal generator decodes the digital audio file and generates the analog audio signal. The audio signal generator decodes compressed sound data received through a wireless communication network and generates the analog audio signal. The audio amplifier amplifies the analog audio signal. The earphone terminal outputs the analog audio signal amplified in the audio amplifier. A direct current blocking capacitor is not equipped between the audio amplifier and the earphone terminal. |
