Earpiece positioning and retaining

摘要

A positioning and retaining structure for an in-ear earpiece. An outer leg and an inner leg are attached to each other at an attachment end and attached to a body of the earpiece at the other end. The outer leg lies in a plane. The positioning and retaining structure have a stiffness that is greater when force is applied to the attachment end in a counterclockwise direction in the plane of the outer leg than when force is applied to the attachment end in a clockwise direction in the plane of the outer leg. The positioning and retaining structure position an earpiece associated with the earpiece in a user's ear and retains the earpiece in its position.
