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. An earphone comprising:
an acoustic driver having a sound-radiating surface; a housing containing the acoustic driver; and a removable ear interface comprising:
a body portion that fits beneath the tragus and anti-tragus and occupies the lower concha of a user's ear when worn by the user,an outlet extending from the body portion and into at least the entrance of the user's ear canal when worn by the user, anda leg extending from the body portion and terminating at an extremity, wherein the leg is formed of a complaint material and applies an upward and backward pressure to the antihelix of the user's ear along substantially the entire length of the leg when the ear interface is fit into the user's ear, and the extremity of the leg seats at the end of the anti-helix under the base of the helix of the user's ear; wherein the sound radiating surface moves along a first axis; the housing includes a front chamber acoustically coupled to the acoustic driver and a nozzle acoustically coupled to the front chamber, the nozzle extending the front chamber towards the user's ear canal along a second axis that is not parallel to the first axis; and the outlet of the ear interface at least partially surrounds the nozzle of the housing.
