Abstract

An audio device and an output method thereof are provided. The audio device includes: an envelope detector configured to detect an envelope of an input audio signal; a power supply which includes a linear power supply (LPS) and a switching-mode power supply (SMPS); an amplifier configured to amplify the input audio signal; an output unit configured to output the audio signal amplified by the amplifier; and a controller configured to compare a voltage level of the detected envelope with a preset level, select one of the LPS and the SMPS based on a result of the comparison, and control the power supply to supply power from the selected one of the LPS and the SMPS to the amplifier.

Description

[0001] This application claims U.S. Provisional Patent Application No. 61 / 693961 filed with the USPTO on August 28, 2012 and Korean Patent Application No. 10-2013-0048530 filed with the Korean Intellectual Property Office on April 30, 2013 priority, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Exemplary embodiments generally relate to providing an audio device and an output method thereof, and more particularly, to an audio device that selects a power supply according to a change of a sound source and an output method thereof. Background technique [0003] The audio device amplifies an input audio signal to output the amplified audio signal through a speaker. Power having a level higher than or equal to that of the audio signal is supplied to an amplifier that amplifies the audio signal. [0004] Types of power supplies may be classified into linear power supplies (LPS) and switch mode power supplies (SMPS). Generall...
