Step 201, detecting a variation of a mutual capacitance between the first electrode and the second electrode by the detection module.
In some embodiments, the detecting, by the detection module, a change amount of a mutual capacitance between the first electrode and the second electrode includes: detecting, by the detection module, a first mutual capacitance value between the first electrode and the second electrode; and calculating a difference value between the first mutual capacitance value and a preset second mutual capacitance value, and taking the difference value as the variation of the mutual capacitance value, wherein the second mutual capacitance value is a base capacitance.
For example, when an external object approaches or contacts the first electrode and the second electrode, the mutual capacitance value between the first electrode and the second electrode may change.
In some embodiments, the method further comprises: detecting, by the detection module, the first mutual capacitance value between the first electrode and the second electrode when an external object is not proximate to the earphone.
Illustratively, the base capacitance may be detected and pre-stored in advance.
In some embodiments, the first mutual capacitance value comprises an equivalent capacitance and a variation of the base capacitance; the equivalent capacitance is formed between the first electrode and the second electrode by a first capacitance, a second capacitance and a third capacitance which are caused by the fact that an external object approaches the earphone, wherein the first capacitance is the capacitance between the external object and the first electrode, the second capacitance is the capacitance between the external object and the second electrode, and the third capacitance is the capacitance between the external object and the system ground; the variation of the base capacitance refers to a variation of the base capacitance caused by a change in electric field distribution when the external object approaches.

Illustratively, the human external object may be, for example, the skin of an ear canal.
As can be seen, in this example, since the target value interval is an effective value interval of the variation of the mutual capacitance of the first electrode and the second electrode in the in-ear state of the earphone, in the subsequent use process, the earphone can be determined to be in the in-ear state according to that the variation of the mutual capacitance detected in real time is in the effective value interval, so as to ensure the accuracy of the detection result.
