Abstract
An earphone control circuit and method, an earphone, as well as an audio output device and method are provided. The earphone control circuit includes a detecting module for detecting whether an earphone is in a wearing state and outputting a detection signal indicating that the earphone is in a wearing state or in a non-wearing state. The earphone control circuit further includes a determining module for outputting a first control signal indicating that the earphone is in a wearing state or outputting a second control signal indicating that the earphone is in a non-wearing state according to the detection signal.
Claims16
An earphone control circuit, comprising:
- a detecting subcircuit for detecting whether an earphone is in a wearing state and outputting a detection signal indicating that the earphone is in a wearing state or in a non-wearing state;
- a determining subcircuit for outputting a first control signal indicating that the earphone is in the wearing state or outputting a second control signal indicating that the earphone is in the non-wearing state according to the detection signal, the first control signal and the second control signal being used to control to output an audio signal through the earphone or a speaker;
- and
- a switch subcircuit for turning on and off the earphone control circuit,
- when the earphone control circuit is turned on, the determining subcircuit outputs the first control signal indicating that the earphone is in the wearing state or outputs the second control signal indicating that the earphone is in the non-wearing state;
- and
- when the earphone control circuit is turned off, the determining subcircuit always outputs the first control signal indicating that the earphone is in the wearing state.
An earphone control method, comprising:
- detecting whether an earphone is in a wearing state;
- outputting a detection signal indicating that the earphone is in a wearing state or in a non-wearing state;
- outputting a first control signal indicating that the earphone is in the wearing state or outputting a second control signal indicating that the earphone is in the non-wearing state according to the detection signal, the first control signal and the second control signal being used to control to output an audio signal through the earphone or a speaker;
- and
- turning on and off an earphone control circuit arranged on the earphone,
- when the earphone control circuit is turned on, the determining subcircuit outputs the first control signal indicating that the earphone is in the wearing state or outputs the second control signal indicating that the earphone is in the non-wearing state;
- and
- when the earphone control circuit is turned off, the determining subcircuit always outputs the first control signal indicating that the earphone is in the wearing state.
