ABSTRACT:
An in-canal hearing aid is inserted and worn within the auditory canal of a hard-of-hearing wearer. This hearing aid has a generally-cylindrical body with a resilient stretchable outer layer and an adjustably expandable member therewithin for changing the diameter of the generally cylindrical body without significantly changing the length thereof. Hearing aid amplifying circuitry are contained within the generally cylindrical body. The body is hingedly flexible and a flex circuit connector is used to support the amplifying circuitry. These features permit rounding the curve of the auditory canal when the hearing aid is inserted. The body of the hearing aid can be selectively expanded for a snug, comfortable fit. A touch control permits the wearer to adjust the volume by touching a single control stem extending from the external end of the hearing aid.
