Abstract
A method for operation of an electronic device and an electronic device are provided. The method includes determining if an object is detected at a first terminal and a second terminal among a plurality of terminals of an ear jack. If the object is detected, the impedance of the second terminal is calculated, and a type of the object is determined according to the calculated impedance.
Claims18
A method of operation of an electronic device, the method comprising:
- detecting an electrical change of a left terminal among a plurality of terminals of an ear jack connector;
- determining that an object is inserted in the ear jack connector based on the detection;
- measuring a first impedance of the left terminal and a second impedance of a ground terminal among the plurality of terminals of the ear jack connector;
- determining whether the object is moisture according to the second impedance of the ground terminal in a state in which the object is detected at both the left terminal and the ground terminal;
- and
- in response to determining that the object is moisture, using a path other than a path associated with the ear jack when outputting an audio signal.
