Provided are an apparatus and a method for restoring from abnormal connection of an audio jack such as partial insertion of an audio jack plug and an audio jack receptacle. In an example, the method comprises the steps of: detecting an effective audio jack connection of an audio jack receptacle and a jack plug; detecting a change in state of a detection switch relating to audio jack connection; applying a vibration signal to a microphone terminal relating to audio jack connection; judging whether the state of the detection switch is uniformly maintained for a predetermined time; and separating a vibration signal from the microphone terminal. |
