摘要： An exemplary earphone detecting circuit includes a signal input terminal, a voltage dividing circuit, a detecting circuit, and a signal output terminal connected electronically in that order. The signal input terminal is connected to an earphone jack of a portable electronic device. The signal output terminal is connected to a microcontroller of the portable electronic device. When the portable electronic device receives a call, the signal input terminal receives a signal and transmits the received signal to the detecting circuit through the voltage dividing circuit, the detecting circuit processes the signal transmitted to the signal output terminal to be constant.
