Embodiments of the present invention provide user equipment, including: a capacitance detection apparatus, a control unit, a microphone, and a prompt apparatus, where the capacitance detection apparatus includes a touch control unit and a capacitance detection unit; the touch control unit is configured to sense a capacitance change of a touch area in which the touch control unit is located, and the microphone is located in the touch area; the capacitance detection unit is electrically connected to the touch control unit, and the capacitance detection unit measures a capacitance value of the touch area according to the capacitance change sensed by the touch control unit, and sends the capacitance value to the control unit; and the control unit determines whether the capacitance value is greater than or equal to a first preset value, and if yes, determines that the microphone is blocked, and controls the prompt apparatus to send prompt information. In this way, a problem of microphone blocking is thoroughly resolved, making an ongoing voice call smoother.
