Definitions

  • the invention relates to a hearing aid, in particular to a hearing aid.
  • Hearing aids are usually used to output (acoustic) sound signals to an ear or the hearing center of the respective hearing device user.
  • hearing aids include a loudspeaker, often referred to as a "handset", which is worn directly in the auditory canal of the respective ear of the hearing device user or is acoustically connected, for example, by means of a sound tube to this auditory canal.
  • a hearing aid for transmitting the sound signal may also be associated with a bone conduction implant, a cochlear implant or the like.
  • hearing aids are designed in particular as hearing aids to compensate for a reduction in the hearing of the hearing device user and thereby usually additionally comprise at least one microphone for detecting (ambient) noise and a signal processing unit, by means of which the detected sounds optionally filtered and then amplified to the speaker be issued.
  • a hearing device may also be a so-called tinnitus masker, by means of which a background or noise signal specific to the hearing device user is generated and output.
  • Modern hearing aids partly have means for (wireless) communication with a separate device.
  • a separate device is usually a control unit by means of which (wireless) processing settings can be transferred to the respective hearing aid, or - in the case of a binaural hearing aid system for supplying both ears of the hearing device user - to a second hearing aid.
  • the control unit may again be, for example to act a smartphone on which a software application for controlling the hearing aid is installed.
  • the separate device may also be an audio signal source which transmits audio signals to be played back to the hearing aid, such as a TV set, a smartphone or the like.
  • Such audio signals are, for example, pieces of music which are otherwise sound signals output via the loudspeakers of the TV set or, in the case in which the hearing device is a headset, also voice signals of a telephone.
  • the invention has for its object to improve a set up for wireless communication hearing aid.
  • the hearing aid according to the invention is preferably a hearing aid.
  • the hearing aid comprises a housing which has a mounting opening and a housing cover for closing this mounting opening.
  • the hearing device further comprises a signal processing unit, which is arranged in the housing, as well as a sealing body for sealing the housing against the entry of impurities, such as liquid, earwax, dust, etc.
  • the sealing body is preferably arranged thereto and provided to seal the housing from the inside thereof. This means that the sealing body in the intended mounting state of the hearing aid - that is, when the housing is closed - arranged in the interior of the housing and is preferably not visible from the outside of the hearing aid.
  • the hearing device also comprises an antenna body for wireless communication (ie signal transmission) with a (preferably separate from the hearing device), preferably electronic device. This antenna body is embedded in the sealing body (ie integrated in this).
  • the separate device is, for example, a control unit which is set up and provided to transmit setting parameters for the signal processing unit wirelessly to the hearing aid.
  • the separate device is a second, binaural hearing device or an electronic device that transmits audio signals wirelessly to the hearing aid, such as a smartphone, a TV set or the like.
  • the signal processing unit is preferably for processing, d. H. for example, for evaluation, filtering, analog-to-digital conversion and the like, the signals received by means of the antenna body ("radio signals"). Furthermore, the signal processing unit is also used in particular for processing sound signals which are detected by means of a microphone which may be included in the hearing aid.
  • the signal processing unit is designed in particular as a non-programmable electronic circuit (eg ASIC). Alternatively, the signal processing unit is formed by a microcontroller in which the functionality for carrying out the signal processing in the form of a software module is implemented.
  • the integration of the antenna body in the seal body leads to a reduction in the number of handled during assembly of the hearing aid items. As a result, assembly effort is saved advantageously. Furthermore, advantageously, space can also be saved.
  • the antenna body has a flat, foil-like structure.
  • "Film-like” means here and below that the wall thickness of the antenna body is small compared to its surface area.
  • the surface of the antenna body is preferably chosen so large that even comparatively weak radio signals can be received.
  • the area covered by the antenna body occupies about half or three quarters of the area covered by the housing, in particular by the housing cover. Due to the film-like structure, the antenna body is known to have a low dimensional stability (i.e., it may collapse or be easily damaged during handling), so that the stability and manageability of the antenna body is advantageously increased due to integration into the seal body.
  • the antenna body is expediently formed from a metal, in particular from copper. This allows a particularly good electrical conductivity and thus also a high reception quality.

  • the antenna body has an exposed, ie not overmolded with plastic, contact portion, by means of which the antenna body is preferably contacted by a solder connection to the signal processing unit, in particular indirectly via a conductor track of the circuit carrier.
  • a solder connection to the signal processing unit, in particular indirectly via a conductor track of the circuit carrier.
  • the use of an LSR as the material for the sealing body is particularly useful because such a liquid silicone regularly has a high temperature resistance compared to conventional injection moldable elastomers and thus is not damaged during the soldering process.
  • the antenna body is contacted to the signal processing unit, for example, by means of a clamping connection, a plug connection or a spring contact.
  • the antenna body it is conceivable within the scope of the invention for the antenna body to be exposed only on an inner side of the sealing body at a partial area of its surface. In the intended mounting state, this exposed portion is in contact with the corresponding contact spring.
  • the antenna body In the case of a spring-loaded contacting the antenna body is also preferably supported via the sealing body against the housing, so that a reliable electrical contact is made possible by means of the spring contact.
  • the antenna body is completely integrated in the sealing body and thus exposed at any point. In this case, the antenna body is contacted via a pointed contact pin with the signal processing unit. This contact pin pierces during assembly of the seal body this at least on the inside and thus is in galvanic contact with the antenna body.
