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.

Abstract translation: 用于稳定地装配在耳中的耳朵单元包括朝向耳朵内侧的第一表面，从耳朵向外面向第二相对表面和形成在第一和第二表面之间的外周表面。 外圆周表面成形为一个递减曲线。 减量曲线的端部之间的距离近似等于在耳朵的耳屏下方形成的第一腔和耳朵的耳轮的下部节点覆盖的第二腔之间的距离。 第一表面设置有提供基本上符合外耳的接触表面的曲率，提供改进的附件，从而使得当耳朵单元定位在耳朵中时耳朵单元能够紧密地配合在外耳上。
