Wearing detection apparatus and method, and earphone

A method for wearing detection, wherein the method is applied to a wearing detection apparatus comprising at least one first capacitive sensor and at least one second capacitive sensor, wherein the first capacitive sensor is disposed at an inner side of the second capacitive sensor, and the method comprises:

• detecting a first coupling capacitance between a touch object and the first capacitive sensor and a second coupling capacitance between the touch object and the second capacitive sensor when an earphone mounted with the wearing detection apparatus is touched by the touch object;
• and
• determining whether the earphone is worn by the human ear according to a difference value between the first coupling capacitance and the second coupling capacitance wherein the determining whether the earphone is worn by the human ear according to a difference value between the first coupling capacitance and the second coupling capacitance, comprises:
• determining that the earphone is worn by the human ear if the difference value between the first coupling capacitance and the second coupling capacitance is greater than a first threshold and the first coupling capacitance is greater than a second threshold;
• or
• determining that the earphone is not worn by the human ear if the difference value between the first coupling capacitance and the second coupling capacitance is less than or equal to a first threshold.

An earphone, comprising:

• the wearing detection apparatus which comprises:
• at least one first capacitive sensor and at least one second capacitive sensor, wherein the first capacitive sensor is disposed on an inner side of the second capacitive sensor;
• and
• a processor configured to detect a first coupling capacitance between a touch member touching the earphone and the first capacitive sensor and a second coupling capacitance between the touch member and the second capacitive sensor when the earphone is touched, and to determine whether the earphone is worn by a human ear according to a difference value between the first coupling capacitance and the second coupling capacitance;
• wherein the processor is specifically configured to:
• determine that the earphone is worn by the human ear if the difference value between the first coupling capacitance and the second coupling capacitance is greater than a first threshold and the first coupling capacitance is greater than a second threshold;
• or
• determine that the earphone is not worn by the human ear if the difference value between the first coupling capacitance and the second coupling capacitance is less than or equal to a first threshold.
