Definitions
- the present invention relates to an otoplastic with at least one acoustic / electrical transducer and / or at least one electrical / acoustic transducer, each with an acoustic input or output, the input or output having a coupling opening on the outer surface of the otoplastic shell via an acoustic conductor connected is.
- the acoustic inputs usually become 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, connected to coupling openings on the outer surface of the otoplastic shell, provided that these entrances and exits are not arranged directly in the surface area of the aforementioned shell.
- acoustic conductor components e.g. in the form of tubes
- the geometrical arrangement and orientation of the coupling opening on the outer surface of the otoplastic shell for input transducers is primarily given by the desired acoustic reception characteristic.
- the acoustic reception characteristic can be determined by the distance and the position of such coupling openings with respect to the otoplastic, a hearing aid.
- the position of a coupling opening on the output side also Output transducer is given, for example, by the relative position of the earmold in the ear canal and the eardrum.
- the coupling opening mentioned is to be arranged in such a way that the additional acoustic conductor mentioned can be optimally guided along the ear cup into the ear canal. If the position of this coupling opening is given by parameters of the type mentioned, then in the otoplastic and in accordance with the available
- Construction space integrated one or more transducers and connected to the coupling openings with the aforementioned acoustic conductors. If one takes into account that in such active earmoulds, such as the hearing aids mentioned, the space available for transducers to be recorded and further functional groups of the electronics, including the battery, is extremely small, it can be seen that it often takes a lot of effort, with the desired position of the coupling openings, the transducer and Integrate acoustic conductors into the earmold so that space and acoustic conditions are optimally taken into account.
- Coupling openings without having to take into account the space required by separate to make acoustic connections.
- the possibility should be opened to flexibly install the above-mentioned transducers where, from the aspect of the most compact possible design, the optimal location is independent of the position of the coupling openings on the outer surface of the otoplastic shell and without the acoustic connection lines to be provided or the construction volume to be provided for this To assign meaning.
- This is achieved with the mentioned otoplastic in that the acoustic conductor is bordered as a channel through the material of the otoplastic shell.
- the acoustic conductor mentioned is integrally molded into the otoplastic or its shell. Since a shell with a given wall thickness is to be provided on the otoplastic anyway, only an insignificant amount of space is required in the otoplastic for the acoustic conductors to be provided towards the coupling opening or openings, and the conductor can essentially be guided from any position. If necessary, several acoustic conductors or channels can also be routed in parallel at least in sections in terms of signal technology. For example, in an area of the otoplastic in which the space for a channel of the desired cross-sectional area is not available, two or more channels parallel in terms of signal technology can make it smaller
- Cross-sectional areas are passed or bypassed: the first-mentioned channel branches out, the branching channels reunite at the end of a given expansion section.
- the at least one channel mentioned has cross-sectional areas and / or cross-sectional shapes varying along its length, in sections, with which the acoustic transmission behavior is specifically optimized. In this way, networks of acoustic impedances are created along the channel, which allow optimum acoustic adaptation.
- the impedance matching can be implemented by at least one matching stub which opens into the channel.
- the otoplastic according to the invention can certainly be designed as a headphone section, the proposed procedure is particularly suitable for hearing aids.
- the channel is part of a ventilation system for the eardrum. This is made possible in particular by the possibilities of impedance matching described above.

- Signal flow / function block diagram a new procedure or a new arrangement for its execution, in which the dynamics of the application area of an earmold is taken into account for its shaping.
- the embodiments of otoplastics described after the manufacturing process are preferably all manufactured using this manufacturing process.
- an otoplastic to be a device that is applied directly outside the auricle and / or on the auricle and / or in the ear canal.
- These include outer ear hearing aids, in-the-ear hearing aids, headphones, noise protection and water protection inserts etc.
- the manufacturing process which is preferably used to manufacture the otoplastics described in detail below, is based on three-dimensionally digitizing the shape of an individual application area for an intended otoplastic, then creating the otoplastic or its shell using an additive assembly process.
- Additive construction processes are also known under the term "rapid prototyping". With regard to such additive processes already used in rapid prototype construction, reference is made, for example, to: • http://ltk.hut.fi/ ⁇ koukka/RP/rptree.html (1)
- Hot melt powder is applied to a powder bed, for example using a roller, in a thin layer.
- the powder layer is solidified by means of a laser beam, the laser beam being driven, inter alia, in accordance with a cut layer of the otoplastic or otoplastic shell by means of the 3D shape information of the individual application area.
- a solidified cut layer of the otoplastic or its shell is formed in the powder, which is otherwise loose. This is lowered from the powder laying level and a new powder layer is applied over it, which in turn is laser-hardened in accordance with a cut layer, etc.
- Laser or stereolithography A first cut layer or an otoplastic or an otoplastic shell is solidified on the surface of liquid photopolymer by means of a UV laser. The solidified layer is lowered and is replaced by
- the second cut layer of the otoplastic or its shell is solidified on the already solidified layer.
- the laser position control takes place, among other things. by means of the 3D data or information of the individual, previously recorded application area.
- Thermojet process The contour formation corresponding to a cut layer of the otoplastic or the otoplastic shell is carried out similarly to an inkjet printer by means of liquid application, etc. carried out according to the digitized SD form information, in particular also of the individual application area. Then the filed section "drawing" is solidified. Again, layer by layer is deposited to build up the otoplastic or its shell in accordance with the principle of the additive build-up method.
- SLS Selective Laser Sintering
- a thin layer of material is deposited on a surface in additive build-up processes, be it like laser sintering or
- Stereolithography over the entire surface, be it in the contour of a cut of the otoplastic or its shell, which is under construction, as in the thermojet process.
- the desired cut shape is then stabilized or consolidated.
- a new layer is placed over it as described and this in turn is solidified and connected to the already finished layer underneath.
- the otoplastic or its shell is created layer by layer by additive layer-by-layer application.
- laser sintering for example, one laser, usually mirror-controlled, solidifies the cut layers of several otoplastics or their shells one after the other before all the solidified cut layers are lowered together. Thereupon, after a new powder layer has been deposited over all the already solidified and lowered cut layers, the formation of the several further cut layers takes place again.
- the respective earmolds or their shells, digitally controlled are manufactured individually.
- Either a single laser beam is used to solidify the multiple cut layers and / or more than one beam is operated and controlled in parallel.
- An alternative to this procedure is to solidify a cut layer with a laser, while at the same time the powder layer is deposited for the formation of a further otoplastic or otoplastic shell.
- the same laser then solidifies the prepared powder layer, corresponding to the cut layer for the further plastic, while the layer solidified before is lowered and a new powder layer is deposited there.
- the laser then works intermittently between two or more otoplastics or otoplastic shells that are being built up, the dead time for laser use resulting from the powder deposit during the formation of one of the shells for Solidification of a cut layer of another otoplastic which is being built up is used.
- FIG. 1 schematically shows how, in one embodiment variant, laser sintering or laser or stereolithography is used to manufacture several otoplastics or their shells industrially in a parallel process.
- the laser with control unit 5 is above the material bed 1 for powder or liquid medium and beam 3 mounted. In position 1 it solidifies the layer Si of a first earmold or its shell, controlled with the first individual data set Di. Then it is moved to a second position on a displacement device 7, where it corresponds to the layer S 2 with the individual data set D 2 created another individual contour.
- a displacement device 7 where it corresponds to the layer S 2 with the individual data set D 2 created another individual contour.
- several of the lasers can be moved as a unit and more than one individual otoplastic layer can be created at the same time.
- layers of individual earmolds or their shells are solidified simultaneously on one or more liquid or powder beds 1, with several simultaneously individually controlled lasers 5.
- the powder dispensing unit 9 after completion of this solidification phase and after stopping the laser deposits a new layer of powder, while in the case of laser or stereo lithography, the layers that have just solidified or the structures that have already solidified are lowered in the fluid bed.
- laser 5 solidifies layer 5 , if it becomes active on the bed 1b, does the powder dispensing device 9a place a new powder layer over the layer S x just solidified on the bed 1 a or does the layer S x in the liquid bed 1 a lower.
- cut layers of more than one earmold or its shells are deposited at the same time, practically in one drawing by an application head or, in parallel, by several.
- materials for additive construction processes which result in a rubber-elastic and yet dimensionally stable shell can be formed, which, if desired, can be realized locally differently up to extremely thin-walled and nevertheless tear-resistant.
- the digitization of the individual application area in particular the application area for a hearing device, in particular in-the-ear hearing device, is carried out at a specialized institution, in the latter case at the audiologist.
- the individual form recorded there, as digital 3D information will be transmitted to a production center, in particular in connection with hearing aids, be it by sending a data carrier, be it by internet connection etc.
- the Otoplasty or its shell in this case the in-the-ear hearing aid shell, individually shaped.
- the finished assembly of the hearing device with the functional assemblies is also preferably carried out there.
- thermoplastic materials used generally lead to a relatively elastic, conforming outer shape
- shape with regard to pressure points in otoplastics or their shells is far less critical than was previously the case, which in particular for in-the-ear
- In-ear earmolds such as ear protection devices, headphones, water protection devices, but in particular also for in-ear hearing aids, can be used in a similar manner to rubber-elastic plugs, and the like their surface nestles optimally on the application area, the ear canal. It is easily possible to incorporate one or more ventilation channels into the in-ear earmold in order to ensure that the resulting, possibly relatively tight fit of the earmold in the
- the interior of the plastic can also be optimized and optimally used, also individually with regard to the individual unit constellation to be recorded, such as with a hearing aid.
- the central production of their shells enables central storage and management of individual data, both with regard to the individual application area and also the individual functional parts and their settings. If, for whatever reason, a shell needs to be replaced, it can easily be made again by calling up the individual data records, without the need for laborious readjustment - as was the case up to now.
- receptacles and holders for components for example: receptacles and holders for components, cerumen Protection systems, ventilation channels in in-ear earmolds, support elements which hold the latter in the ear canal in in-ear earmolds, such as so-called claws (English channel locks).
- FIG. 4 shows, for example and schematically, an in-the-ear otoplastic 11, for example an in-the-ear Hearing aid in which the acoustic output 13 to the eardrum is protected by a cerumen protective cap 15.
- this protective cap 15 has been applied to the shell 16 of the otoplastic 11 as a separate part and fixed, for example by gluing or welding.
- the cerumen protective cap 15 a is integrated directly onto the shell 16 a of the otherwise identical in-ear earmold 11 a by using the additive construction methods mentioned.
- FIG. 5 there are no such interfaces at the connection points schematically indicated by P in FIG. 4, where a material inhomogeneity or interface necessarily arises in conventional methods; the material of the shell 16a passes homogeneously into that of the cerumen protective cap 15a over.
- cerumen protection systems and other functional elements can be integrated using the above-mentioned manufacturing process.
- Ventilation channels are hardly suitable for the respective acoustic Adapted to requirements.
- active earmolds such as in-the-ear hearing aids, they can hardly help to effectively solve the feedback problem from the electromechanical output transducer to the acoustic / electrical input transducer.
- passive in-ear earmolds such as hearing protection devices, they are unable to support the desired protective behavior and at the same time maintain the desired ventilation properties.
- ventilation measures are proposed for in-ear earmolds, in particular for in-the-ear hearing aids or hearing protection devices, but also for otoplastics that only partially protrude into the ear canal, such as headphones, which at least partially remedy the above-mentioned disadvantages of known measures.
- - are at least partially open to the wall of the auditory canal, - which are completely closed against the wall of the ear canal.
- the cross-sectional shape of the ventilation grooves 20 provided can already achieve a certain degree of predictability and influence on the acoustic transmission conditions along this groove, if they are in contact with the inner wall of the auditory canal.
- the acoustic behavior is also dependent on the length with which the groove 20 extends along the outer wall 18 of the otoplastic.
- FIG. 7 (c) to (f) show further ventilation groove profiles which are additionally protected against cerumen.
- the profile of the groove 20c shown in Fig. 7 (c) is T-shaped.
- the cross-sectional shape of the wide groove part 27d to 27f is formed with a different shape, in accordance with FIG. 7 (d) in the form of a circular sector or in accordance with the sector of an ellipse, in accordance with FIG. 7 (e) in a triangular shape, in accordance with FIG. 7 (f) in a circular or elliptical manner.
- ventilation grooves 29 which, progressing in their longitudinal direction, define different profiles, as can be seen in FIG 8 are shown assembled from profiles according to FIG. Similar to the design of passive electrical networks, the acoustic transmission behavior of the groove in the ear canal can be mathematically modeled and checked, then integrated into the in-ear earmold or its shell.
- cerumen-protected sections can be provided on exposed parts in this regard, as shown at A in FIG. 8.
- the ventilation grooves provided longer than is basically the case due to the longitudinal expansion of an in-ear earmold under consideration.
- FIG. 9 this is achieved in that such grooves 31 with a configuration as are shown, for example, with reference to FIGS. 7 and 8 are guided in predetermined curves along the surface of the otoplastic, for example as shown in FIG. 9 , practical as grooves that wrap around the thread like an otoplastic.
- Further optimization flexibility is achieved in that not only one ventilation groove, but several are guided on the surface of the otoplastic, as is shown schematically in FIG. 10.
- the high flexibility of the groove design means that depending on the application area in the auditory canal, different dimensions are targeted
- Cerum protection and acoustic transmission conditions can be optimized ventilation grooves along the otoplastic surface.
- Ventilation systems with fully integrated channels This variant of the new ventilation systems is based on ventilation channels that are completely integrated into the otoplastic at least in sections and closed against the wall of the ear canal. This system is then explained on the basis of its training on an otoplastic shell. However, it should be emphasized that if no further units are to be integrated in the otoplastic in question and it is designed as a full plastic, the following explanations naturally also relate to a channel guide through the full plastic mentioned.
- FIG. 11 shows different cross-sectional shapes and area ratios of the proposed ventilation channels 33a to 33e.
- the ventilation duct 33a built into the otoplastic shell 35a has a rectangular or square cross-sectional shape.
- the ventilation channel 33c provided has a circular or elliptical cross-sectional shape, while in the embodiment variant according to FIG. 11 (d) it has a triangular cross-sectional shape.
- the otoplastic shell has a complex internal shape, for example a mounting part 37 integrated thereon.
- the ventilation channel 35e provided here is designed with a cross-sectional shape that also uses complex shapes of the otoplastic shell. Accordingly, it extends its cross-sectional shape partially complicates with the mounting bar 37 attached to the shell 35e.
- FIG. 12 shows a variant of a fully integrated ventilation duct 39, which has different cross-sectional shapes and / or cross-sectional dimensions along its longitudinal extent, as shown, for example, in the otoplastic shell 41, with which the acoustic transmission behavior can be optimized in the sense of realizing different acoustic impedance elements .
- ventilation channels in particular the closed construction shown in this section, may at least in sections at the same time act as acoustic conductor sections which are active on the output side on the output side Transducers, as can be used on the output side of microphones, for example in in-the-ear hearing aids.
- FIGS. 9 and 10 in analogy to FIGS. 9 and 10, show how, on the one hand, on the respective otoplastic 43, the integrated ventilation channels explained in this section are extended by appropriate web guidance or on the other hand like two or more of the channels mentioned, if necessary. with different and / or varying channel cross sections, analogous to FIG. 12, can be integrated on the otoplastic.
- sections 2a) and 2b) which can be combined as required, open up a myriad of design variants of the new ventilation systems and, in particular, a large degree of freedom, due to the various parameters that can be dimensioned, for optimal wax protection for the respective individual otoplastic and to create optimal acoustic transmission conditions.
- the specific individual configuration of the system is preferably calculated or modeled, taking into account the needs mentioned. Then the individual earmould is realized.
- the manufacturing process explained at the beginning with an additive construction principle, as is known from prototype construction, is particularly suitable for this, which is then controlled with the optimized model result.
- FIG. 15 schematically shows a longitudinal sectional view of an in-ear earmold
- FIG. 16 shows a schematic cross-sectional view of a section of this earmold.
- the earmold - e.g. for receiving electronic components - has a shell 45, which consists of stocking-like, thin-walled elastic material.
- Embodiment smooth on the outside - shell skin is ensured - where desired - by ribs 47 which are integrally fitted on the inside of the shell and which are made of the same material with respect to the shell skin.
- the course of the wall thickness of shell skin 45, the density and shape of the ribs 47 previously calculated and then the earmold built up according to the calculated data is extremely well suited for this.
- the design of the in-ear earmold just explained can be combined with a ventilation system, as was explained with reference to FIGS. 7 to 14.
- the ribs provided to influence the shape stability or bendability in certain areas of the otoplastic can also be formed with a different cross-sectional profile, possibly also progressively extending in their longitudinal extent from one cross-section to the other.
- the in-ear earmold can, as mentioned, in addition to the inner rib pattern, as shown in FIGS. 17 and 18, also External rib patterning can be provided. According to FIGS. 18 and 19, a pattern of ribs 51 is worked up on the outer surface of the otoplastic 49, possibly with different density, orientation and profile shape.
- this can be used for the otoplastics with a cavity considered here, but also for otoplastics with no cavity, for example with no electronic components, e.g. for
- Hearing protection devices or water protection devices Such an otoplastic is shown schematically in a cross-sectional illustration in FIG. 20.
- the interior 53 is made of extremely compressible material, for example
- Ventilation channels or free spaces can be formed at the same time, as is shown purely schematically and, for example, by the path P.
- the shell skin 55 or 45, according to FIGS. 15, 16 and 17, can certainly be made of electrically conductive material, which at the same time creates an electrical shielding effect for internal electronic components. This may also apply to the filling 53 according to FIG. 20.
- an otoplastic was shown using the example of an in-the-ear otoplastic, the shell of which is shape-stabilized with internal and / or external ribs, which results in an extraordinarily light and selectively formable construction.
- this design can also be used for outer ear earmolds if necessary.
- FIG. 21 shows a further embodiment variant of an in-the-ear earmold which can be bent or compressed in a targeted manner.
- the shell 61 of an otoplastic such as in particular the shell of an in-the-ear hearing device, has a corrugated or corrugated tube formation 63 in one or more predetermined areas, by means of which it can bend or is compressible.
- FIG. 21 shows this procedure using the shell of an in-ear earmold, this procedure can be implemented and if necessary also for an outer ear earmold. Again, the manufacturing method explained at the outset is preferably used for this purpose.
- the inner volume of the otoplastic can be filled with the filling material corresponding to the requirements, or built-in internals can be embedded in such filling material, which results in a higher stability of the device and improved acoustic conditions.
- an in-ear earmold 65 is shown schematically and in longitudinal section, in which the shape of the inner space 67 essentially corresponds to the shape of the electronics module 69 to be accommodated, which is shown schematically in FIG. 23.
- the otoplastic 65 is made of rubber-elastic material and, as shown in FIG. 23, can be put over the electronics module 69.
- the shape of the interior 67 is such that the one or more modules to be accommodated are positively positioned and held directly by the otoplastic 65. Because of this procedure, it is easily possible to use one and the same electronic module 69 with different ones
- the earmold practically becomes an easily replaceable disposable accessory for the in-the-ear hearing aid. Not only to change conditions in the application area, namely the Ear canal to take into account, but also simply for reasons of contamination, the earmold 65 can be easily replaced.
- This concept can even be used to carry out medical applications, for example in the case of ear canal infections, for example by applying medication to the outer surface of the otoplastic, or at least in order to use sterilized otoplastics at regular intervals.
- FIGS. 22 and 23 can of course be combined with the concepts set out in sections 2 and 3, and the otoplastic 65 is preferably manufactured according to the manufacturing process explained in section 1), which allows the formation of the most complex internal shapes for play and allows vibration-free recording of module 69.
- the phase plate 1 which is otherwise provided in conventional in-the-ear hearing aids, is built integrally with the otoplastic, for example as part of the module holder.
- the layer-by-layer build-up method described in section 1) is implemented, as shown by dash-dotted lines in FIG. 22 and in the direction indicated by the arrow AB, then it should be possible without further ado, the otoplastic in the mentioned direction AB according to requirements to be made from different materials in the respective areas.
- This also applies to the earmoulds set out in sections 2) and 3) and to those explained in the following sections 5), 6) and 7).
- FIG. 24 shows a further embodiment of an otoplastic, again as an example using an in-the-ear hearing device, which enables the internal internals to be replaced simply and quickly.
- it is proposed to design the otoplastic shell on an in-the-ear otoplastic with internals, as can be seen in FIG. 24.
- fast-acting closures such as snap-in closures, latch-in closures or even bayonet-like closures
- housing parts 73a and 73b on the in-ear earmold it is possible to quickly separate housing parts 73a and 73b on the in-ear earmold, to remove the internals such as electronic modules and to re-install them in a new shell, if necessary with a changed outer shape or basically in a new bowl, even if this is necessary for cleaning reasons, sterility reasons, etc.
- it is intended to throw away the already used shell it is readily possible to design the connections of the shell parts in such a way that the shell can only be opened in a destructive manner, for example by providing locking elements such as latches that are not accessible from the outside and cutting the shell open for their removal becomes.
- acoustic / electrical transducers or electro-acoustic output transducers to the surroundings of the hearing aid on the input or output side via acoustic conductors assembled as independent parts, namely tube-like structures. or, in particular with acoustic / electrical transducers on the input side, these with their receiving surface directly in the
- a converter module 75 has an acoustic input or output 77.
- the shell 79 of the otoplastic of an in-the-ear or of an outer ear hearing device or a headphone has an acoustic conductor 81 integrated in it. It lies at least in sections and, as shown in FIG. 25, within the wall of the otoplastic shell 79.
- the respective acoustic impedance of the acoustic conductor 81 is preferably adapted by means of acoustic stub lines or line sections 83.
- each is individually adapted to its respective wearer. Therefore, it would be extremely desirable to have every otoplastic manufactured, as mentioned in particular to mark every in-ear earmold, especially every in-ear hearing aid. It is therefore proposed to provide an individual marking in the otoplastic or in its shell, by indentations and / or by bulges, which, in addition to the individual customer, eg manufacturer,
- Product serial number, left-right application etc. may contain. Such a marking is created in a much preferred manner during the manufacture of the earmold using the removal method described under 1). This ensures that any confusion of the earmolds is excluded from production. This is particularly important in the subsequent, possibly automated assembly with further modules, for example the assembly of in-the-ear hearing aids.
- the dynamics of the application area can be recorded by means of X-ray images.
- the computing unit 97 controls the manufacturing process 99 for the earmold. If, for example, and as is usual until now, in-ear earmolds are manufactured with a relatively hard shell, the computing unit 97 calculates the best fit for the dynamic data stored in the storage unit 95 and, if necessary, as shown schematically at K, other manufacturing parameters the earmold, so that optimal wearing comfort is achieved in everyday life, while maintaining its functionality.
- the computing unit 97 determines which otoplastic areas are to be designed and how with regard to their flexibility, flexibility, compressibility, etc. On the output side, as mentioned, the computing unit 97 controls the manufacturing process 99, preferably in the process the manufacturing process as set out in Section 1) as the preferred process.
