Abstract
An electronic device and noise canceling method thereof is provided. The electronic device may include a housing; at least one output circuit arranged inside the housing and configured to generate a first signal; an opening formed on one side of the housing; a hole connected to the opening; a receptacle arranged inside the hole, and configured to receive an external connector, and electrically connected to the at least one output circuit; at least one sensor arranged within a predetermined proximity range to at least one of the opening and the receptacle; and a control circuit electrically connected electrically to the at least one output circuit, the receptacle, and the at least one sensor, wherein the control circuit is configured to detect the external connector approaching to at least one of the opening and the receptacle using the at least one sensor, to generate a second signal upon detection of the approaching external connector, and to control the at least one output circuit to change the first signal at least partly based on the second signal.
