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 users ear and retains the earpiece in its position.

1. A positioning and retaining structure for an earphone, the positioning and retaining structure comprising an outer edge and an inner edge, each extending from a base to be coupled to the earphone and meeting at a tip distant from the base,
wherein the base comprises a cushion structure shaped to substantially fill the concha of a user when the earphone is worn in user's ear, the outer edge having differing radii of curvature along its length, including a first section at the base having a first radius of curvature and a second section near the tip having a second radius of curvature greater than the first radius of curvature, such that the outer edge is more-sharply curved near the base and less-sharply curved near the tip.
