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 apparatus for interfacing with an earphone, the apparatus comprising:
- an external port configured to interface with the earphone;
- and
- at least one processor configured to control to apply a voltage to a MIC_BIAS terminal if connection of the earphone to the external port is sensed, and continue to apply the voltage to the MIC_BIAS terminal when disconnection of the earphone is sensed.
An electronic device for interfacing with an earphone comprising:
- an external port configured for interface with the earphone;
- and
- at least one processor configured to control to apply a voltage to a MIC_BIAS terminal if connection of the earphone to the external port is sensed, and continue to apply the voltage to the MIC_BIAS terminal if disconnection of the earphone is sensed,
- wherein the generation of noise of the MIC_BIAS terminal caused by applying of a periodic voltage resulted from loose insertion of the earphone is prevented.
A method for interfacing with an earphone in an electronic device, the method comprising:
- checking if the earphone is uninstalled promptly after connection of the earphone is sensed in an external port;
- and
- if the earphone is sensed to be uninstalled, continuing to apply a voltage to a MIC_BIAS terminal,
- wherein the generation of noise of the MIC_BIAS terminal caused by applying of a periodic voltage resulted from loose insertion of the earphone is prevented.
