Summary: | An earphone comprises a processing unit, a camera shooting module and a touch control sensor. The camera shooting module shoots an ear canal image and obtains an ear canal curvature characteristic point. The touch sensor senses a first contact feature point and a second contact feature point of the earphone and the outer ear. The processing unit draws an imaginary circle. The imaginary circle hasa preset radius, passes through the first contact feature points and the second contact feature points, and surrounds the ear canal curvature feature points. An imaginary connecting line is arranged between the circle center of the imaginary circle and the ear canal curvature feature point. When the ear canal curvature feature points are located above the circle center of the imaginary circle, ifthe first contact feature point is located on the left side of the virtual on-line, the earphone is determined to be worn on the left ear, otherwise, determining that the earphone is worn on the rightear and switching the corr |
