The present invention relates to an active noise control audio input/output device comprising: a sound input unit which receives a sound signal; at least two sound output units which output a sound signal; a connection unit which is inserted to a connection terminal of a terminal and includes a first sound signal input terminal, a second sound signal input terminal, a sound signal output terminal, a ground terminal, and a power input terminal, to relay a signal generated between the audio input/output device and the terminal; a circuit unit which is positioned and is electrically connected between the sound output unit and the connection unit and transmits an electric signal generated in the terminal and the audio input/output device; and an active noise control unit which is electrically connected to the circuit unit to recognize a noise generated around the audio input/output device and generates a cancelation sound of the noise. According to the invention, the power input terminal which supplies power to the active noise control unit is provided at the connection unit, it is possible to thereby drive an active noise control function by the power supplied from the terminal, a separate power supply means is not required to facilitate portability, it is possible to reduce the weight generated from a power supply means loaded in the audio input/output device, it is possible to thereby minimize discomfort at the time of wearing, positions of a plurality of input/output terminals provided at the connection unit correspond to positions of contact pins of standard three-pole and four-pole connection terminals, it is possible to normally input and output a sound through the audio input/output device even when the audio input/output device of the invention having the standard 3-pole and four-pole connection terminals without power supply is connected, and thus there is an advantage of providing high compatibility. |
