Abstract
Using a 4-pin audio jack, 3-pin signal interfaces including the ground interface are assigned with conventionally used earphone/microphone functions (one microphone input and one speaker output), while the other interface corresponding to the fourth pin is assigned with a function of microphone input for voice recognition in high noise environment. This function is made effective only when a connected audio device requires such function.
