Definitions

  • the invention relates to a housing for receiving various functional elements of the BTE hearing aid.
  • BTE hearing aids usually have a sickle, half moon or banana shaped housing for receiving various functional elements, such as microphone, amplifier, handset, battery, etc., as well as one at the upper end of the housing attached hearing aid angle, mounting bracket or suspension hook for holding the hearing aid to the ear.
  • Such hearing aids are for example from the DE 199 30 935 C1 . DE 296 02 921 U1 , G 94 09547.7 or G 89 15 608.0 known.
  • Conventional housings are typically industrially mass produced housings of generally rectangular cross-section and predetermined dimensions. This results in disadvantages in terms of comfort and function.
  • the result of the substantially rectangular cross-section is that conventional housings usually do not lie over a large area but more or less only abut the inner surface of the auricle and the opposite lateral portion of the head, as illustrated in FIGS. 7 and 8.
  • bruising can easily result for the user, preventing a symptom-free fit.
  • the invention has for its object to provide a housing for a BTE hearing aid for receiving various functional elements of the BTE hearing aid, which provides a high level of comfort, is visually inconspicuous and even with violent head movement, e.g. during exercise, itself, i. without earmold, ensures an improved grip on the pinna, as well as a corresponding manufacturing process.
  • a housing for a BTE hearing aid which has the features of claim 1 or a method with the steps of claim 10.
  • the housing according to the invention is characterized in that the outer surface of the housing is adapted at least at the area of the retroauricular region of an auricle corresponding to the cymbal cavum in such a way that it conforms to the anatomical structures of this area of the retroauricular Region of the auricle can be snuggled form-fitting.
  • the housing according to the invention in the wearing state is therefore nestled at least on the region of the retroauricular region of the auricle corresponding to the cymbal cavum.
  • the housing according to the invention therefore ensures in the worn state a pressure and thus uncomfortable fit of the housing and a high level of comfort.
  • a hearing aid with the custom housing according to the invention can thus be reliably anchored in the retroauricular region of the auricle using only the individually available anatomical structures.
  • the housing according to the invention is not limited in its dimensions to standard dimensions or standard cross-sections. Rather, depending on the anatomical structures in the retroauricular region, the housing cross-section may vary over the housing length such that the housing volume defines the volume of the retroauricular region defined between the inner surface of the pinna and the opposite lateral portion of the head for placement of the various functional elements of the Hearing aid, such as microphone, amplifier, handset, battery, ear protectors, leisure / music electronics and speakers, so-called "in ear monitoring" elements, etc., optimally uses. In particular, beyond the area corresponding to the cymbal cavum, the housing can generally be extended over the entire length of the retroauricular region.
  • This extension of the housing in the longitudinal direction of the retroauricular region offers the possibility of appropriately distributing the various functional elements of the hearing aid over the entire housing length, which is determined solely by the length of the retroauricular region, in the housing volume in such a way that the housing in FIG Wear state in a side view of the head, ie in a plan view of the auricle, remains inconspicuous, ie does not go beyond the outer contour of the helix of the pinna.
  • the arrangement of the various functional elements can be selected in particular depending on the dimension of the functional elements and the respective available volume ranges of the housing.
  • the housing according to the invention is preferably designed as a hollow profile construction with at least one housing opening, which is formed on the part of the housing outer surface visible from the outside in the wearing state of the housing, ie in the part of the housing outer surface, which does not abut in the retroauricular region of the auricle in the wearing state of the housing but is accessible from the outside.
  • This ensures that that portion of the housing outer surface, which should be snugly nestled in the wearing state in the retroauricular region of the auricle, rests as consistently as possible without interruptions or unevenness due to constructive or manufacturing technology.
  • the hollow profile construction of the housing allows the weight of the housing and thus also the weight of the hearing aid to be minimized overall. This has a positive effect on the wearing comfort.
  • the hollow profile construction allows a maximum housing volume for distribution and arrangement of the various functional elements.
  • the at least one housing opening is closed by a so-called front plate, which is embedded in the housing opening in such a way that its outer surface merges substantially flush into the outer surface of the housing.
  • a trained basket, cage or plate-like executed functional element carrier can be removably inserted in a recess formed in the front panel, the all or individual functional elements, e.g. a power source (battery, battery, etc.) carries.
  • the functional element carrier By removing the functional element carrier, the corresponding functional elements, e.g. the power source, for the purpose of replacement, repair, etc. easily remove from the housing.
  • access to at least a part of the housing volume and / or at least part of the functional elements carried by the functional element carrier can be provided by a lid pivotally mounted on the functional element carrier.
  • a power source arranged in the housing can be exchanged via the cover without having to remove the functional element carrier from the housing.
  • the housing is made of a UV-curing polymer having a substantially constant wall thickness.
  • a sound outlet connection for example a connecting piece, for connecting a sound transmission hose leading into the auditory canal directly at the upper end of the housing may be suitably provided.
  • the housing according to the invention can be customized by an outside vorgeshene functional coating.
  • the coating gives a dull or glossy impression as well as a certain color shade can be achieved.
  • the housing according to the invention can be manufactured by a method as shown in claim 10. According to this method, first an impression, e.g. a real model made of plaster, silicone, plastic, etc. or a three-dimensional virtual model, at least the area of the retroauricular region of an auricle corresponding to the cymbal cavum. Subsequently, a housing blank is made, which corresponds at least in a portion of the individual impression. Finally, if necessary, the package blank is finally finished to customer specifications, e.g. ground, polished, coated, etc. to obtain the desired housing.
  • customer specifications e.g. ground, polished, coated, etc.
  • the impression can be made by a manually made impression (gypsum, silicone, plastic, etc.) of the at least the cymbal cavum corresponding section of the retroauricular Region of the auricle.
  • the individual impression thus obtained can then be digitized three-dimensionally using a CAD system to form a data set.
  • the area of the retroauricular region of the auricle corresponding to the cymbal cavum can also be optically scanned. On the basis of the scanning result, the virtual impression thus obtained can then be digitized three-dimensionally using a CAD system to form a data record.
  • the digitized creation of a virtual three-dimensional impression of at least the area of the retroauricular region corresponding to the cymbal cavum offers the possibility of forming the housing blank with the section corresponding to the individual impression by an additive construction method, which is also known as "rapid prototyping", such as laser sintering. Laser or stereolithography and thermojet process, which is controlled according to the record.
  • rapid prototyping such as laser sintering.
