ELECTRONIC DEVICE FOR OUTPUTTING SOUND AND SOUND OUTPUT METHOD USING SAME

An electronic device outputting a sound according to embodiments of the disclosure may comprise memory storing at least one instruction, a processor executing the at least one instruction, at least one speaker, and an audio processing module processing the input audio signal and outputting the processed input audio signal to the at least one speaker. The audio processing module may include a digital amplifier amplifying a digital audio signal, a digital-to-analog converter (DAC) converting the digital audio signal into an analog audio signal, an analog amplifier amplifying the analog audio signal, a boost amplifier boosting the analog audio signal to a reference high voltage or more, and at least one noise gate removing noise included in the analog audio signal. The digital amplifier may apply a positive (+) digital gain to the digital audio signal. The analog amplifier may apply a negative (-) analog gain to the analog audio signal.
