| description | A wearable device is provided and includes a plurality of speakers including a first speaker, a second speaker, and an Nth speaker, a plurality of digital to analog converter (DAC)s including a first DAC connected to the first speaker, a second DAC connected to the second speaker, and an Nth DAC connected to the Nth speaker, an audio signal processing module including N DAC output paths configured to filter an audio signal according to each frequency band and output the audio signal, a memory; and a processor electrically connected to the plurality of DACs, the audio signal processing module, and the memory, wherein the memory includes instructions causing the processor to, when the audio signal is reproduced, analyze a frequency component included in the audio signal, activate the N DAC output paths when the frequency component included in the audio signal has a full band range, activate only a DAC output path for processing a specific frequency band among the N DAC output paths when the frequency component included in the audio signal has only the specific frequency band, and output the audio signal through a speaker connected to the activated DAC output path. |
