  • STATE DETECTION DEVICE FOR USE IN AN AUDIO INTERFACE
    Publication number: 20220386050
    Abstract: A state detection device in an audio interface includes: a first voltage detection circuit, a second voltage detection circuit and a state determination circuit. The first voltage detection circuit is coupled to a first contact and a second contact of an audio jack socket, for detecting a voltage across the first contact and the second contact to generate a first detection value. The second voltage detection circuit is coupled to a third contact of the audio jack socket, for detecting a voltage on the third contact to generate a second detection value. The state determination circuit is coupled to the first voltage detection circuit and the second voltage detection circuit, for determining a water ingress state of the audio jack socket according to the first detection value, and a connector type of an audio plug that is inserted into the audio jack socket according to the second detection value.
