Abstract
A headset includes a connector configured to couple to a terminal, where the connector of the headset includes at least one functional pin. The headset further includes a sensor circuit and a logic control circuit. The sensor circuit is coupled to a functional pin of the connector of the headset using the logic control circuit. The sensor circuit is configured to sense a wearing status of the headset, and output a trigger signal to the logic control circuit when the wearing status changes. A sensor is added to the headset, and sensor information is fed back to the terminal.
Claims20
A headset, comprising:
- a connector configured to couple to a terminal, wherein the connector comprises a first functional pin and a second functional pin;
- configured to:
- sense a wearing status of the headset;
- and
- output a trigger signal to a logic control circuit when the wearing status changes, wherein the logic control circuit is configured to:
- couple at least one functional pin to the sensor circuit;
- receive the trigger signal from the sensor circuit;
- and
- change, based on the trigger signal, a first voltage value on the at least one functional pin to a second voltage value to trigger the terminal to perform a target operation event based on the second voltage value, wherein the target operation event is preset for the second voltage value;
- a voltage regulator comprising a voltage regulation input end and a voltage regulation output end;
- a first switching switch comprising:
- a first control end;
- a first fixed end;
- a first connection end;
- and
- a second connection end;
- and
- a comparator comprising:
- a first voltage input end coupled to the first functional pin and configured to input a third voltage value from the first functional pin;
- a second voltage input end coupled to the voltage regulation output end and configured to input a reference voltage value from the voltage regulation output end;
- and
- coupled to the first control end and configured to:
- output a comparison result;
- determine, based on the comparison result, whether the first functional pin is coupled to a power supply circuit or a microphone (MIC) circuit of the terminal;
- control the first fixed end to couple to the first connection end when the first functional pin is coupled to the power supply circuit;
- and
- control the first fixed end to couple to the second connection end when the first functional pin is coupled to the MIC circuit.
A terminal configured to be coupled to a headset having a sensor circuit and a connector comprising a first functional pin and a second functional pin, the terminal comprising:
- a headset jack configured to connect to the connector, wherein the terminal is configured to be coupled to the headset using the first functional pin and the second functional pin when the connector is plugged into the headset jack;
- a microphone (MIC) circuit;
- a power supply circuit coupled to the headset jack and configured to supply power to the sensor circuit;
- a sensor identification circuit coupled to the headset jack and configured to determine whether a sensor signal is transmitted to the headset;
- and
- a switching switch coupled to the headset jack and configured to control the terminal to provide the MIC circuit or the power supply circuit for the headset.
A control method implemented by a headset comprising a logic control circuit and a connector including a functional pin coupled to the logic control circuit, the method comprising:
- sensing a wearing status of the headset using a sensor in a sensor circuit of the headset;
- outputting a trigger signal to a logic control circuit of the headset based on the wearing status;
- changing, using the logic control circuit, a first voltage value on the functional pin to a second voltage value, wherein the connector is configured to couple the headset to a terminal;
- and
- triggering, based on the second voltage value, the terminal to perform a target operation event, wherein the target operation event is preset for the second voltage value.
