Enhanced comfort earbud

摘要

An earbud that uniformly conforms to the ear canal and maintains a constant and comfortable radial pressure on the ear canal regardless of size. The earbud is designed to extrude distally when placed inside a small canal and yet still conforms to the canal while maintaining the aforementioned comfortable radial pressure. A wax bridge may be added to provide an added layer of wax protection to the earbud.

主权项

1. An earbud for insertion into an external ear canal, comprising:
a cylindrically shaped body having proximal and distal ends and having a cavity located at its distal end for receiving and connecting to a hearing aid's receiver or audio tube; a flange made of resilient material extending radially and distally from the circumference of the proximal end of the body and terminating in a relatively more rigid retainer ring, wherein the circumference of the flange increases with longitudinal distance from the proximal end of the body up to a maximum value at an apex and then decreases to the circumference of the retainer ring; wherein the longitudinal distance from the apex of the flange to the retainer ring is shorter than the longitudinal distance from the apex of the flange to the proximal end of the body and further wherein the rate at which the circumference of the flange decreases with respect to longitudinal distance from the apex of the flange to the retainer ring is greater than the rate at which the circumference of the flange increases with respect to longitudinal distance from the proximal end of the body to the apex of the flange; and, an acoustic port located at the proximal end of the body for conducting sound produced by the hearing aid receiver into the external ear canal.
