ABSTRACT:
The hearing aid system includes a hearing aid case which is designed to be positioned behind the ear of a user, a tube for conducting sound from the case to the ear canal of the user, and a eartip for anchoring the end of the tube within the ear canal of the user. The tube is formed in a preformed shape of a material with sufficient rigidity to support the hearing aid in a proper position on the user's ear. The eartip may be one of several different designs which secures an end of the tube in place in the ear canal in a comfortable manner without the need for an expensive custom made ear mold and without complete occlusion of the ear canal. A combination of the light weight and small size of the case, the rigidity of the preformed tube, and one of the eartips for anchoring the tube in the ear canal allow the system to be held in place securely without the need for either an inflexible and aesthetically unpleasing ear hook or an expensive custom made ear mold.
