Abstract
A shell in shell hearing aid system and hearing aid wax guard apparatus. The hearing system includes a hearing aid electronic and transducer unit having a housing and stem. The system further includes a custom shell component that is formed for affixation around the stem. The system further includes an end cap that connects to the end of the stem and holds the custom shell around the stem. The end cap can be the hearing aid wax guard apparatus having a series of flap seals, a bell-shaped dome and tear drop speaker opening.
Claims23
A hearing aid apparatus, comprising:
- a electronics and transducer unit;
- a custom shell connected to and surrounding a portion of the unit;
- and
- an end cap connected to the unit.
A hearing aid kit, comprising:
- an electronics and transducer unit having a housing and a stem having a protrusion and a barb;
- an inner shell optionally adapted to fit onto and surround the stem and to cradle a portion of the housing, the inner shell having a housing shell portion and a stem-shell portion;
- an outer shell adapted to be formed around the inner shell, the outer shell having an outer surface molded to an ear canal;
- and
- an end cap having an opening adapted to receive the barb, the end cap being adapted to retain the inner and outer shells on the stem.
A hearing aid system, comprising:
- an electronics and transducer unit having a housing and a stem having a protrusion and a barb, the housing having an operational face including a transducer opening;
- an inner shell surrounding the stem and cradling a portion of the housing, the inner shell having a housing shell portion, a stem-shell portion and an opening through which the protrusion and barb protrude;

- a housing having a dome and a hollow interior, the housing being oriented about a longitudinal axis;
- a side channel through the dome and oriented generally perpendicular to the longitudinal axis;
- an opening to the side channel, the opening defining a tear drop a portion of the tear drop being disposed through the channel, and another portion of the teardrop forming an indentation;
- and
- an opening to the hollow interior oriented about the longitudinal axis opposite the dome, the opening defining a lip adjacent the opening.
A hearing aid, comprising:
- an electronics and transducer unit having a stem and a housing;
- means to receive and surround a portion unit;
- means to surround the means to receive and surround a portion of the unit;
- and
- means to retain the means to receive and surround the unit on the unit.
