Method of preparing a hearing aid, and a hearing aid
The present invention relates generally to hearing aids and to methods of manufacturing hearing aids. The invention further relates to shells for hearing aids and methods of manufacturing thereof. The invention, more particularly, relates to custom-made BTE hearing aids. A shell comprising a first part, and a second part, wherein said first part is adapted to fit the contour of the cleft between a pinna and the skull of an individual is provided. The shell may be part of a hearing aid ( 17 ) that is connected with a tube ( 9 ) in a first end and an earplug ( 20 ) in a second end. In a third aspect of the invention a method of preparing the shell is disclosed and in a fourth aspect a method of manufacturing a hearing aid is also disclosed.
1. A method of preparing a Behind-The-Ear hearing aid for an individual hearing aid user, said method comprising the steps of
providing an impression having a first part and a second part, the first part being directly cast by contact with the cleft between the skull and a pinna of said user, and the second part being adapted to complete the impression, said step of providing an impression comprising providing an impression of a part of an armature of a spectacle frame,
molding a shell using the impression as a form, said step of molding a shell including providing an indentation adapted to fit said part of the armature of the spectacle frame,
cutting said shell, whereby to provide a housing that has an aperture encircled by an edge,
providing a faceplate, which faceplate has an entrance opening,
adhering said faceplate to said edge,
providing a module for supporting an amplifier assembly and a battery compartment, and
inserting and securing said module through said entrance opening, whereby to complete the Behind-The-Ear hearing aid.
2. The method according to claim 1 comprising arranging at least one microphone in said housing.
3. The method according to claim 1 , comprising arranging an acoustic output transducer in said housing.
4. The method according to claim 3 , comprising connecting a sound tube to said housing.
5. The method according to claim 4 , comprising a step of providing an outlet opening arranged at least partially in said second part.
6. The method according to claim 5 , comprising connecting said sound tube to the acoustic output transducer out through said outlet opening.
7. A Behind-The-Ear hearing aid comprising a housing, a faceplate and a module,
wherein said housing is manufactured by providing an impression having a first part and a second part, the first part being directly cast by contact with the cleft between the skull and a pinna of said user, and the second part being adapted to complete the impression, said impression including an impression of a part of an armature of a spectacle frame, molding a shell using the impression as a form, said shell including an indentation adapted to fit said part of the armature of the spectacle frame, and cutting said shell, whereby to provide a housing that has an aperture encircled by an edge,
wherein said faceplate has an entrance opening and is adhered to said housing at said edge, and
wherein said module includes an amplifier assembly and a battery compartment, and is adapted for mounting in the housing by inserting and securing said module through said entrance opening.
