Abstract

The aim of the invention is to increase hearing aid packing density. To this end, at least two elements that are to be assembled on the hearing aid and that are produced from different materials are produced by two- or multicomponent injection molding. For example, in the case of a two- or multipart shell of a hearing aid, the sealing (7a) is coinjected on a part ( 1) in the marginal area (3) together with the material of said shell part.</SDO AB>

Claims (16)

1. A method of producing hearing devices in which at least two parts made of different materials are produced and assembled, characterized in that the parts are produced, already joined-together, by two-component or multi-component injection-molding, said parts being produced from different material components.
2. The method as claimed in claim 1, characterized in that, as one of the parts, at least a portion of the housing is produced by two-component or multi-component injection-molding.
3. The method as claimed in either of claims 1 and 2, characterized in that, as one of the parts, a seal is produced by two-component or multi-component injection-molding, preferably at least a portion of the housing and a seal.
4. The method as claimed in one of claims 1 through 3, characterized in that, as one of the parts, an acoustic lead at the output of an electro-mechanical transducer of the hearing device is produced by two-component or multi-component injection-molding.
5. The method as claimed in one of claims 1 through 4, characterized in that, as one of the parts, an acoustic lead at the input of an acoustic-electric transducer is produced by two-component or multi-component injection-molding.
6. The method as claimed in one of claims 1 through 5, characterized in that a receiving seat for parts of the hearing device in the housing is produced, preferably together with at least a portion of the housing, by two-component or multi-component injection-molding.
7. The method as claimed in one of claims 1 through 6, characterized in that a boundary portion of a through-opening in the housing is produced, preferably together with at least a portion of the housing, by two-component or multi-component injection-molding.
8. The method as claimed in one of claims 1 through 7, characterized in that, on the outside of a housing portion, at least one predetermined surface area is produced, together with the housing portion, by two-component or multi-component injection-molding, preferably as a design element and/or as a surface area which has a feel which helps in using the hearing device.
9. A hearing device assembled from a plurality of parts, characterized in that at least two of the parts, made of different materials, are produced together by two-component or multi-component injection-molding.
10. The hearing device as claimed in claim 9, characterized in that one of the parts is a portion of the hearing device housing.
11. The hearing device as claimed in either of claims 9 and 10, characterized in that one of the parts is a seal, and the second part is preferably at least a portion of the housing.
12. The hearing device as claimed in one of claims 9 through 11, characterized in that one part is an acoustic lead at the output of an electro-mechanical transducer of the hearing device.
13. The hearing device as claimed in one of claims 9 through 12, characterized in that one of the parts is an acoustic lead at the input of an acoustic-electric transducer of the hearing device.
14. The hearing device as claimed in one of claims 9 through 13, characterized in that at least one receiving seat for a further part of the hearing device is provided in the housing, preferably for an electro-mechanical tranducer of the hearing device, and in that the receiving seat is produced together with at least one further part, preferably a portion of the housing, by two-component or multi-component injection-molding.
15. The hearing device as claimed in one of claims 9 through 14, characterized in that the housing has a through-opening for an operating member, preferably a switch member, and the border of the opening is one of the parts, preferably with the housing and/or the operating member as the second of the parts.
16. The hearing device as claimed in one of claims 9 through 15, characterized in that surface areas of different material than adjoining housing areas are formed on the outside of the housing, and are produced together with these by two-component or multi-component injection-molding.
