Abstract
An ear jack for detecting an earphone plug is provided. The ear jack includes a housing, a plurality of pins, a first detection part, a second detection part, and a controller. The housing includes a cavity for inserting terminals of the earphone plug. The plurality of pins are installed on an inner circumference surface of the housing and are in selective contact with a corresponding terminal of the earphone plug. The first detection part detects insertion of a first terminal of the earphone plug. The second detection part detects the insertion of the first terminal. The controller detects the insertion of the earphone plug when the first detection part and the second detection part both detect the insertion of the first terminal.
Claims20
An ear jack for detecting an earphone plug comprising terminals of at least three poles, the ear jack comprising:
- a housing comprising a cavity for inserting the terminals of the earphone plug;
- a plurality of pins installed on an inner circumference surface of the housing and being in selective contact with a corresponding terminal of the earphone plug;
- a first detection part for detecting an insertion of a first terminal that is an end of the earphone plug;
- a second detection part for detecting the insertion of the first terminal, wherein the second detection part comprises a plate spring installed to be pressed upwards in a bottom surface of the housing so as to provide an electrical connection with the controller that is controlled based on the insertion of the first terminal;
- a controller for detecting the insertion of the earphone plug when the first detection part and the second detection part both detect the insertion of the first terminal;
- and
- an actuator installed between the second detection part and an end part of the earphone plug such that the actuator is pressed by the end part, and the actuator presses the plate spring to electrically connect and disconnect the plate spring from the controller.
A portable terminal comprising an ear jack, the ear jack comprising:
- a housing comprising a cavity for inserting terminals of at least three poles of an earphone plug;
- a plurality of pins installed on an inner circumference surface of the housing and being in selective contact with a corresponding terminal of the earphone plug;
- a first detection part for detecting an insertion of a first terminal that is an end of the earphone plug;
- a second detection part for detecting the insertion of the first terminal, wherein the second detection part comprises a plate spring installed to be pressed upwards in a bottom surface of the housing so as to provide an electrical connection with the controller that is controlled based on the insertion of the first terminal;
- a controller for detecting the insertion of the earphone plug when the first detection part and the second detection part both detect the insertion of the first terminal;
- and
- an actuator installed between the second detection part and an end part of the earphone plug such that the actuator is pressed by the end part, and the actuator presses the plate spring to electrically connect and disconnect the plate spring from the controller.
