  • Method for determining a wearing state of an earphone, and earphone system
    Patent number: 12089031
    Abstract: A method for determining a wearing state of an earphone. Acceleration data are acquired using an acceleration sensor. A time characteristic of the acceleration data is ascertained, and curve segments are ascertained. The curve segments are each formed by first and second sections. A first wearing state of the earphone is determined, in which the earphone is worn on the ear, if a curve segment including a first section having a positive course and a second section having a negative course is ascertained, and if a first characteristic shape is ascertained for the curve segment. A second wearing state of the earphone is determined, in which the earphone is not worn on the ear, if a curve segment including a first section having a negative course and a second section having a positive course is ascertained, and if a second characteristic shape is ascertained for the curve segment.
