Definitions
- the present invention relates to an earmold with at least one acoustic / electrical converter and / or at least one electrical / acoustic transducer, each with an acoustic input or output, the input or output with a coupling opening on the outer surface the earmold shell via an acoustic conductor connected is.
- acoustic inputs too acoustic / electrical input transducers, microphones and / or the acoustic outputs of electrical / acoustic output transducers, loudspeakers, via acoustic conductor components, e.g. in the form of tubes, with coupling openings on the outer surface of the Otoplastikschale connected, provided these inputs or outputs not directly in the surface area of the mentioned Shell are arranged.
- This procedure is under various aspects disadvantageous.
- the geometric arrangement and orientation of the Coupling opening on the outer surface of the earmold to input transducers is primarily given by desired acoustic reception characteristic. So can through the distance and the location of such coupling openings, concerning the earmold, a hearing aid, the acoustic Receiving characteristic to be determined. Also the location a coupling opening on the output side of a Output transducer is e.g. by the relative position of Otoplasty in the ear canal and eardrum given.
- the mentioned coupling opening should be arranged that the mentioned additional acoustic conductor optimally the Pinna can be guided along in the auditory canal. Is the position of this coupling opening by parameters of Given the type mentioned, then must in the earmold and according to the available Design space one or more transducers integrated and with the mentioned acoustic conductors with the Coupling openings are connected.
- the space for recording transducer and further functional groups of the electronics including battery is extremely small, it can be seen that often a lot of trouble, if desired location of the Coupling openings, the transducers and acoustic conductors in to integrate the earmould so that the space and The acoustic conditions optimally taken into account becomes.
- the mentioned acoustic conductor molded integrally into the earmold or its shell.
- a shell is provided with a given wall thickness, will be provided for the acoustic conductor towards the coupling orifices, only negligible construction volume claimed in the earmold and the conductor guide can be essentially of any to any position. If necessary, you can also several acoustic conductors or channels at least sections are signal-wise led in parallel.

- Laser sintering solidifies e.g. the one laser, usually mirror-controlled, one behind the other the cut layers several earmolds or their shells, before all solidified cut layers are lowered together. Then, after laying a new layer of powder over all already solidified and lowered cut layers, in turn, the formation of several more Sectional layers.
- this parallel production will be the respective earmolds or their shells, digital controlled, individually manufactured.
- An alternative to this procedure is, respectively using a laser to solidify a cut layer while at the same time for the formation of another earmold or Otoplastikschale the powder layer is deposited. After that the same laser becomes the prepared powder layer, according to the cut layer for the further plastic solidified while lowered the previously solidified layer and there is a new powder layer is deposited. The laser then works intermittently between two or more Erective earmolds or earmold shells, the powder deposited by the formation of one of the Schalen resulting laser insert dead time for the Solidification of a cut layer of another in construction understood earmold is exploited.

- the layer-to-layer build-up method set forth in section 1) as in FIG. 22 dash-dotted lines and in the direction indicated by the arrow AB
- the otoplastic in the above-mentioned construction direction AB it would be readily possible for the otoplastic in the above-mentioned construction direction AB to be arranged according to requirements respective areas made of different materials.
- This also applies to the earmolds described in Sections 2) and 3) as well as to those explained in the following sections 5), 6) and 7).
- Fig. 24 is another embodiment of a Otoplasty, again as an example using an in-ear hearing aid, which is a simple, quick Replacement of internal fittings allows. in principle is suggested to be attached to an in-ear earmold Built-in earmold shell multi-piece and form assemblable, as Fig. 24 shows.
- outer ear and in-ear hearing aids usual, intended acoustic / electrical converter or electro-acoustic output transducer input or on the output side assembled as separate parts acoustic conductors, namely tube-like structures, with the environment of the hearing aid to couple, or, especially at the input side acoustic / electrical Transducers, these with their receiving surface directly in the Place areas of the surfaces of the hearing aid, if necessary only through small cavities and Protective measures separate from the environment.
- One Converter module 75 has an acoustic input and output 77 on.
- This concept allows along the Hearing placed and where desired acoustic To provide input openings 85, this over in the Otoplasty or its shell 87 integrated acoustic Head 89 to the intended acoustic / electrical Coupling converter 91, essentially independent of where these transducers 91 are installed in the hearing aid. So is in Fig. 26 only shown for example, two transducers to centralize a module and its inputs with the desired receiving openings 85 through the mentioned guide the acoustic conductor 89 to connect.
- each one is individually for their adapted to each carrier. That's why it would be extreme desired, each manufactured earmold, as mentioned especially any in-ear earmold, especially so each in-ear hearing aid to mark. It will therefore proposed in the earmold or in the Shell, by indentations and / or by bulges one provide individual labeling, which together with the. individual orderer, e.g. Manufacturer, Product serial number, left-right application, etc. included can. Such labeling is far more preferred Manner in the manufacture of the earmold with the created under 1) Abtrag psychologist. This will be Ensures that from the production any confusion Otoplastics is excluded. Especially important this is the case for the following, possibly automated Assembly with other modules, such as the Assembly of in-ear hearing aids.

- Bezüglich akustischem Verhalten: Die heute bekannten Belüftungsrinnen sind kaum an die jeweiligen akustischen Erfordernisse angepasst. So können sie kaum, bei aktiven Otoplastiken, wie z.B. bei Im-Ohr-Hörgeräten, dazu beitragen, die Rückkopplungsproblematik von elektromechanischem Ausgangswandler zu akustisch/elektrischem Eingangswandler wirksam lösen zu helfen. Auch bei passiven Im-Ohr-Otoplastiken, wie Gehörschutz-Einrichtungen, vermögen sie nicht, das erwünschte Schutzverhalten zu unterstützen und gleichzeitig die erwünschten Belüftungseigenschaften beizubehalten.
- Cerumenempfindlichkeit: Die heute eingesetzten Belüftungsrinnen in der Aussflächen von Im-Ohr-Otoplastiken sind äusserst Cerumenbildungs-empfindlich. Diese vermag, je nach deren Intensität, rasch die vorgesehene Belüftungsrinnen bezüglich ihrer Belüftungseigenschaften zu beeinträchtigen, wenn nicht gar vollständig zu verstopfen.
