Flexible hearing aid tip with an integral receiver
First Claim
Patent Images
1. A flexible tip for a hearing aid comprising:
- an inner portion of the tip defining a bore having a proximal end and a distal end, the proximal end of the bore adapted to be disposed adjacent an eardrum and a housing formed in the tip at the bore, the inner portion being formed of a first material having sufficient flexibility to allow the inner portion to navigate the S-shaped path of an ear canal while maintaining sufficient stability to prevent the bore from collapsing when the tip is inserted into an ear canal;
a receiver mounted within the housing; and
a mushroom shaped portion, integral with the inner portion, and extending radially from the proximal end of the inner portion, that creates a seal in the bony portion of an ear canal when the tip is inserted into an ear, the mushroom shaped portion being formed of a second material, the second material having a greater compliance than the first material.

Abstract
A flexible tip for a hearing aid includes a mushroom shaped tip, an inner portion having a bore and a receiver mounted within the bore. The receiver can be housing and sealed within a receiver housing. The receiver housing can include a spring having a high compliance along a longitudinal axis and transverse axis, to provide flexibility in the flexible tip. The spring can also having a high stiffness along a radial direction about the circumference of the spring to provide support of the flexible tip from radially directed loads.

19. A method for placing a receiver adjacent to an eardrum comprising:
-
providing a hearing aid with a flexible tip having an inner portion defining a bore and a mushroom-shaped portion integral with the inner portion, and extending radially from a proximal end of the inner portion, the flexible tip having the receiver mounted within the bore in a housing which is integrally formed in the bore, the inner portion being formed of a first material having sufficient flexibility to allow the inner portion to navigate the S-shaped path of an ear canal while maintaining sufficient stability to prevent the bore from collapsing when the tip is inserted into an ear canal, and the mushroom shaped portion being formed of a second material, the second material having a greater compliance than the first material; placing the hearing aid within an ear of a user; and placing the flexible tip adjacent to the eardrum within the ear of the user such that the mushroom shaped portion creaties a seal in the bony portion of an ear canal. - View Dependent Claims (20)
