Abstract
An apparatus and method for interfacing with an earphone are provided. The method includes checking if the earphone is uninstalled promptly after the connection of the earphone is sensed in an external port and if it is sensed that the earphone is uninstalled, continuing to apply a voltage to a MIC_BIAS terminal. The generation of a noise of the MIC_BIAS terminal caused by applying of a periodic voltage resulted from loose insertion of the earphone is prevented.
Claims20
An electronic device to interact with an earphone, the electronic device comprising:
- an external port configured to receive a plug of an earphone;
- and
- at least one processor configured to:
- control an application of a voltage to a MIC_BIAS terminal of the electronic device when an insertion of the plug into the external port is sensed by the electronic device,
- detect that the inserted plug is loose in the external port by sensing periodic signal changes of a sensed pin associated with an installation or an uninstallation of the plug, and
- in response to detecting that the plug is loose in the external port, provide a notification of the detected loose plug to prevent a generation of a noise from the MIC_BIAS terminal caused by an application of a periodic voltage resulting from the loose plug.
