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.

1. An earphone comprising:
an acoustic driver that converts applied audio signals to acoustic energy; a housing containing the acoustic driver, the housing including a front chamber acoustically coupled to the acoustic driver, wherein the housing includes a nozzle that extends the front chamber towards the ear canal of a user when the earphone is worn; and an ear interface comprising:
an outlet extending from the body portion and into at least the entrance of the user's ear canal when worn by the user,
wherein the outlet at least partially surrounds the nozzle of the housing and provides a passageway for conducting acoustic energy to the user's ear canal, anda retaining member extending from the body portion,
wherein the retaining member is formed of a compliant material and applies pressure to the antihelix of the user's ear along substantially the entire length of the retaining member when the ear interface is worn by the user,the retaining member lies in a plane when not worn by the user, andthe plane in which the retaining member is angled relative to the housing, such that the retaining member is tilted outward from the side of the user's head when the earphone is seated in a user's ear.
