Definitions

  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals, which are processed according to a compensation of the respective hearing impairment and in particular amplified.
  • a hearing device for this purpose usually comprises an input transducer, for example in the form of a microphone, a signal processing unit with an amplifier, and an output transducer.
  • the output transducer is usually implemented as a miniature speaker and is also referred to as a handset or receiver. In particular, it generates acoustic output signals which are conducted to the patient's hearing and generate the desired auditory perception in the patient.
  • BTE hearing aids behind-the-ear, also behind-the-ear or BTE
  • a housing with components such as a battery and the signal processing unit is worn behind the ear.
  • the receiver can either be directly in the auditory canal of the wearer (so-called ex-earphone hearing aids or receiver-in-the-canal (RIC) hearing aids).
  • the receiver is arranged inside the housing itself and a flexible, also referred to as a tube sound tube directs the acoustic output signals of the receiver from the housing to the ear canal (hose hearing aids).
  • ITE hearing aids in-the-ear, also IDO or in-the-ear
  • CIC hearing aids are similar to ITE hearing aids, but are worn fully in the ear canal.
  • the standard housing of such an ITE hearing aid here is composed of individual parts that must be produced in various manufacturing processes. While the faceplate, that is to say the housing cover which conventionally carries the electronics of the hearing aid, can be produced by means of injection molding, the housing shells of ITE hearing aids are usually produced in the laboratory or by means of a 3D printing method (eg SDL-Delective Deposit Lamination method) The faceplate is then attached to the housing shell and adjusted to the contour of the shell, making the shell production in particular costly and expensive, which has an overall negative effect on the overall costs and the manufacturing process of an ITE hearing aid.
  • a 3D printing method eg SDL-Delective Deposit Lamination method
  • the invention is therefore based on the object to provide a way to make the production of such an ITE hearing aid simpler and more cost-effective.
  • the two partial shells here form the housing shell of the hearing aid housing.
  • the subshells form a common interior, in which hearing device components such as a microphone, a signal processing unit and other electronic components are arranged.
  • Both partial shells have an outer contour adapted to an ear canal of the hearing device wearer, at least in a partial area, so that the housing adapts its contour to the contour of the ear canal and provides the hearing aid wearer with a correspondingly comfortable wearing feeling.
  • the (usually curved) axis of the ear canal in this case also forms an axis of the housing in particular.
  • the subshells are releasably secured to each other forming the interior.
  • the partial shells are then attached to each other again.
  • the partial shells can be non-destructively separated from each other and open the housing accordingly.
  • the partial shells are pinned to form the interior.
  • preferably slim pins are used, which take up little space and can be easily removed again with the appropriate tool in the case of a desired separation of the two partial shells.
  • the housing additionally comprises a faceplate.
  • the faceplate closes the housing shell formed from the two partial shells and forms together with both partial shells of the housing of the hearing aid.
  • the faceplate is expediently prefabricated as a separate component independently of the partial shells, preferably also by means of an injection molding process. Accordingly, only one manufacturing process must be used to manufacture the housing.
  • the faceplate is expediently equipped with standard components such as microphones, battery contacts, inductive antenna and the like. Further, the faceplate may be formed with actuators, such as rotary or switching, which allow operation of the hearing aid (for example, by changing a hearing program).
  • the faceplate and the partial shells are preferably latched to form a closed housing.
  • the faceplate is formed integrally with at least one partial shell.
  • the faceplate in this case is therefore not a separate component but part of the at least one partial shell.
  • the faceplate is made in one piece with at least one partial shell.
  • At least the partial shells forming the interior for accommodating hearing device components can be positioned in the ear canal of a hearing device wearer.
  • This is the case in particular with "classic" ITE hearing aids.
  • the housing shell is inserted here in the ear canal, while the faceplate is visible and palpable from the outside.
  • the faceplate is positioned in the ear canal of a hearing aid wearer and accordingly no longer visible from the outside.
  • a hearing aid that can be inserted into the ear of a hearing aid wearer is designed with a previously described housing.
  • the directed to the housing dependent claims, as well as the benefits given for this purpose can be transferred to the hearing aid accordingly.
  • the hearing aid expediently comprises at least one microphone, a signal processing unit with an amplifier and a receiver, as well as further electronic and functional components.
  • the respective components are preferably disposed within the housing and / or are components of the housing.
  • the hearing aid is preferably designed as an ITE hearing aid.
  • the hearing aid is designed as a CIC hearing aid.
  • a housing 1 for a deployable in the ear of a hearing aid wearer hearing aid 3 is shown.
  • the housing 1 of the hearing aid 3 comprises two partial shells 5, 7, which form the housing shell 8 of the housing 1 and together have an interior space 9 to accommodate hearing aid components (not shown).
  • this is a classic ITE hearing device 3, in which the partial shells 5, 7 are positioned in the ear canal 10 of the hearing device wearer.
  • the partial shells 5, 7 each have, in a partial region 11, an outer contour 13 which is adapted to an ear canal 10 of the hearing aid wearer and enables a comfortable fit of the hearing device 3.
  • the partial shells 5, 7 share the housing 1 in the present case along a surface 15 extending parallel to the axis A of the ear canal 10 of the hearing aid wearer.
  • This division enables demolding of the two partial shells 5, 7 and thus opens up the possibility of producing the partial shells simply and inexpensively by means of injection molding ,
  • a division of the housing 1 along an oblique to the axis A of the ear canal 10 of the hearing aid wearer surface is possible.
  • the partial shells 5, 7 are releasably secured to each other while forming the interior 9.
  • pins are used, which allow a simple attachment to each other as well as a non-destructive opening of the housing shell 8 by separating the partial shells 5, 7th
  • the housing comprises a faceplate 17, which is also manufactured as a separate component by means of injection molding.
  • a faceplate 17 which is also manufactured as a separate component by means of injection molding.
  • an integral production of the faceplate 17 with at least one of the two partial shells 5, 7 is also possible.
  • FIGS. 2 and 3 the partial shells 5, 7 are each shown separately.
  • the demolded interior 9 is visible for receiving hearing device components
  • Fig. 3 shows the at least in the portion 11 of the ear canal 10 of the hearing aid wearer adapted outer contour 13th
