1. An in-ear earphone with a capacitive sensing function, comprising:

  • a case, having an accommodating portion and an extension tube, wherein an ear tip is sleeved on the extension tube;

    a speaker, disposed in the accommodating portion, wherein a sound emitting surface of the speaker faces the extension tube;

    a circuit board, disposed in the accommodating portion, and electrically connected to the speaker, wherein a sensing chip is disposed on the circuit board; and

    a capacitive sensing unit, comprising a sensor and a conducting element, wherein the sensor is disposed in the case, and is electrically connected to the sensing chip through the conducting element;

    wherein when the extension tube of the case is inserted into an ear canal of a user, the sensor returns a sensing signal to the sensing chip through the conducting element, and the sensing chip sends a control signal according to a capacitance change of the sensing signal, so as to control an operation of the speaker.
