wherein the additional function terminal is configured to provide power from the power source to the additional function circuit as drive power, and
wherein the additional function terminal is included in at least one of the microphone terminal, the audio terminal, and the ground terminal and a non-contact area is further provided between the additional function terminal and the at least one of the microphone terminal, the audio terminal, and the ground terminal.

2. The audio device of claim 1 , wherein the additional function circuit comprises an active noise cancelling (ANC) block.

3. An audio device connected to an electronic device, the electronic device comprising an active noise canceling (ANC) power source and an on/off switch that controls the ANC power source, the audio device comprising:
an audio side connector comprising:
a microphone terminal configured to output a microphone signal to the electronic device,
at least one audio terminal configured to receive an audio signal from the electronic device,
an ANC terminal, and
a ground terminal; and

an ANC block configured to receive a power input from the electronic device to remove noise around the audio device,
wherein the ANC terminal is configured to provide power from the ANC power source to the ANC block as drive power, and
wherein the ANC terminal is included in any one of the areas of the microphone terminal, the audio terminal, and the ground terminal and a non-contact area is further provided between the ANC terminal and the at least one of the microphone terminal, the audio terminal, and the ground terminal.

4. The audio device of claim 3 , wherein the audio terminal comprises a left (L) channel audio terminal and a right (R) channel audio terminal.

5. The audio device of claim 4 , wherein, when the ANC terminal is included in the area of the audio terminal, the non-contact area is further provided between the ANC terminal and the R channel audio terminal to partition the ANC terminal and the R channel audio terminal in the area of the audio terminal.

6. The audio device of claim 3 , wherein the electronic device is equipped with an electronic device side connector comprising:
