<p>The present invention relates to an audio input/output device and provides an audio input/output device comprising: a connection section which comprises a plurality of sound signal output ends, a ground end, and a voice signal input end, and which is inserted into the ear-jack end of a terminal so as to relay a signal generated in the audio input/output device and the terminal; and an active noise control section which recognizes the noise generated around the audio device and generates a canceling sound against the noise, wherein the active noise control section is supplied with power required for carrying out an active noise control function from the terminal via any one of the plurality of sound signal output ends or the voice signal input end. The present invention does not require a separate battery or a charging means for using the active noise control function, and is thus easy to carry. In addition, the present invention can minimize discomfort while being worn by reducing the weight of the battery, etc. Also, the present invention can reduce the size of the audio input/output device because no space for storing a separate battery therein is necessary.</p> |
