Improved earpiece

(57)    Abstract

Device called ear unit for stable fittings in an ear, characterised in that said ear unit (10) is shaped as a decremental curve and that the distance between the ends (5, 8) of the decremental curve is approximately equal to the distance between a first cavity from the under the tragus (4) of the ear and second cavity covered by the lower node (15) of the antihelix of the ear, the upper part of the curve projecting in underneath a flap (2) covering the lower part of the second cavity, and said ear piece having a curvature providing an improved attachment in that said curvature follows the bottom of the ear mussel (22). The ear unit (10) optionally comprises a part (T) extending downwards, the transition between said part (T) and the ear piece is formed in such a way that it aligns along the intertragic notch (14). The ear unit is optionally arranged with at least one unit from the group comprising ear phone and microphone. The ear unit is optionally arranged with a unit from the group of wireless communication unit for use with mobile phone and the like, and wired communication unit for use with music system and the like. Said ear unit (10) is arranged with a curvature (21) in such a way that it traces along the bottom of the ear mussel (22) when the ear unit (10) is positioned into the ear and optionally arranged with an incision (20) in such a way that it aligns along the intertragic notch (14) when said ear unit is brought into the ear. This provides a further stability and increased comfort
