Abstract
Disclosed are a sound source output apparatus based on amplification power source control according to a volume level and an operating method thereof. The sound source output method according to the exemplary embodiment of the present disclosure includes a volume level sensing step of sensing a volume level; a control step of generating a voltage control signal by determining an amplification power voltage for an amplification operation based on the sensed volume level; a power applying step of applying the adjusted amplification power voltage based on the voltage control signal; an audio signal generating step of generating an audio signal by performing an amplifying operation of the sound signal which is converted based on the amplification power voltage; and an audio output step of outputting the audio signal.
