IN-EAR EARPHONE WITH CAPACITIVE SENSING FUNCTION
First Claim
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.

Abstract
An in-ear earphone with a capacitive sensing function is provided. The earphone includes a case, a speaker, a circuit board, and a capacitive sensing unit. The case has an extension tube and an accommodating portion. An ear tip is sleeved on the extension tube. The accommodating portion accommodates the speaker, the circuit board, and the capacitive sensing unit. A sound emitting surface of the speaker faces the extension tube. The circuit board is electrically connected to the speaker, and a sensing chip is disposed on the circuit board. The capacitive sensing unit includes a sensor and a conducting element. The sensor is electrically connected to the sensing chip through the conducting element. When the extension tube is inserted into an ear canal of a user, the sensor returns a sensing signal to the sensing chip, and the sensing chip sends a control signal to control sound output of the speaker.
