Hearing Aid Retaining Member Concha Abutment Design

The patent incorporates a protrusion on the earpiece that engages with a corresponding recess in the sportslock during the attachment process. This preliminary mechanical guidance ensures that the sportslock is pushed all the way onto the earpiece, preventing partial attachment that would cause skin annoyance or dome interference, while still maintaining ease of operation through the self-aligning feature.

The patent divides the sportslock into distinct functional segments: a body portion that contacts the ear, an elongated portion that provides structural support, and a retention feature (such as a flange or extended rim) that specifically prevents dome displacement. This segmentation allows each part to perform its specific function optimally - the body portion ensures secure attachment without skin irritation, while the retention feature independently prevents the dome from falling off inside the ear canal.
