Abstract
Disclosed is a voltage control device including a voltage detector detecting an output voltage output from an output port of a mobile communication device; and a voltage control circuit bypassing the output voltage to an earpiece in which a speaker and a microphone are integrally formed when the output voltage detected by the voltage detector is between a first voltage and a second voltage higher than the first voltage.
