Abstract
Circuits, methods, and apparatus for improved audio connectors. One example provides an audio connector, that, for purposes of activating circuitry to receive signals from a microphone, does not detect the presence of an audio jack until the audio jack is inserted far enough into the audio connector that a microphone contact on the audio jack comes into contact with a microphone signal pin on the audio connector. To prevent the redirection of audio signals away from an audio jack when the audio jack is partially extracted from the audio connector, such partial extractions are not detected by audio signal pins.
Claims20
An audio connector having a front and a back and comprising:
- a first detection switch located near the back of the audio connector;
- and
- a second detection switch located between the first detection switch and the front of the audio connector.
A method of detecting an insertion of an audio jack into an audio connector comprising:
- providing a resistance to the audio jack with at least one retention clip;
- detecting a partial insertion of the audio jack;
- providing a first signal, the first signal indicating the partial insertion;
- detecting a further insertion of the audio jack;
- and
- providing a second signal, the second signal indicating the further insertion.
An electronic device comprising:
- an audio connector having a front and a back and comprising:
- a first detection switch located near the back of the audio connector;
- and
- a second detection switch located between the first detection switch and the front of the audio connector;
- a first circuit coupled to the first detection switch;
- and
- a second circuit coupled to the second detection switch.
