CAFCFirst Claim
1. An ear unit for stably fitting in an ear having an antihelix, a tragus and a concha surrounded by the antihelix, wherein said ear unit is shaped as a decremental curve, said decremental curve being configured to correspond to the antihelix of the ear with a surface shaped in such a way that the decremental curve falls along an inner part of the antihelix and is partly positioned under the antitragus, wherein the decremental curve comprises two ends, a distance between the two ends being approximately equal to a distance between a first cavity formed under the tragus of the ear and a second cavity covered by a lower node of the antihelix of the ear, and wherein, when the ear unit is positioned in the ear, the ear unit is provided with a curvature conforming to an inner surface of the concha, andwherein the curvature extends to an outer circumferential surface of the ear unit, the outer circumferential surface contacting an inner circumferential surface of the antihelix when the ear unit is positioned in the ear.

Abstract
An ear unit for stably fitting in an ear includes a first surface facing inwardly toward the ear, a second, opposite surface facing outwardly from the ear and an outer circumferential surface formed between the first and second surfaces. The outer circumferential surface is shaped as a decremental curve. The distance between the ends of the decremental curve is approximately equal to the distance between a first cavity formed under the tragus of the ear and second cavity covered by the lower node of the antihelix of the ear. The first surface is provided with a curvature that provides a contact surface that substantially conforms to the concha, providing an improved attachment, thereby enabling the ear unit to fit closely against the concha when the ear unit is positioned into the ear.

10. An ear unit for stably fitting in an ear having an antihelix, a tragus and a concha surrounded by the antihelix, the ear unit comprising:
-
a first contact surface contacting an inner circumferential surface of the antihelix, said first contact surface being shaped as a decremental curve conforming to the inner part of the antihelix, wherein the decremental curve comprises two ends, a distance between the two ends being approximately equal to a distance between a first cavity formed under the tragus of the ear and a second cavity covered by a lower node of the antihelix of the ear; and a second contact surface contacting the concha, the second contact surface being provided with a curvature in a direction orthogonal to a normal of the first contact surface and configured to conform to an inner surface of the concha, thereby enabling the ear unit to fit closely against the concha when the ear unit is positioned into the ear, wherein the curvature extends to an outer periphery of the first contact surface. - View Dependent Claims (11, 12)

13. An ear unit for stably fitting in an ear having an antihelix, a tragus and a concha surrounded by the antihelix, wherein said ear unit is shaped as a decremental curve, said decremental curve being configured to correspond to the antihelix of the ear with a surface shaped in such a way that the decremental curve falls along an inner part of the antihelix and is partly positioned under the antitragus, wherein the decremental curve comprises two ends, a distance between the two ends being approximately equal to a distance between a first cavity formed under the tragus of the ear and a second cavity covered by a lower node of the antihelix of the ear, and wherein, when the ear unit is positioned in the ear, the ear unit is provided with a curvature conforming to an inner surface of the concha, said curvature being orthogonal to the decrimental curve.
