Definitions

  • the invention is in the field of hearing aids and relates to a set, a method and a hearing aid according to the preambles of the corresponding independent claims.
  • Set and method according to the invention are used for the production of the hearing aid.
  • the hearing aid belongs to the category of hearing aids that are at least partially worn in the ear canal, which have a casting cavity in a provisional state and which are adapted to this auditory canal by pouring the casting cavity into an auditory canal.
  • the hearing aid according to the invention has a cast molded body which is precisely adapted to the auditory canal of a wearer.
  • the hearing aid according to the invention is preferably a hearing aid, a radio receiver or a device with a different acoustic function.
  • the hearing aid according to the invention can also have only one protective function, that is to say it can be, for example, a protective plug against noise or water.
  • Hearing aids of the type mentioned are described for example in the publications EP-0821541 (or US-6249587), EP-0821542 (or US-6097826) or EP-0821543 (or US-6052473).
  • the hearing aids described in these publications have a stretchable membrane which extends over the lateral surface of the device and on an outer end plate and on the inner end side forming speakers or attached to a speaker holding ring.
  • the faceplate, membrane and loudspeaker essentially delimit the casting cavity or the molding molded therein.
  • the electronic components of the device are at least partially poured into the molded body quasi-floating, such that their relative positions are also adapted to a certain extent to the shape of the individual auditory canal.
  • a pouring template equipped for supplying the casting material and the venting of the casting cavity is placed on the end plate, and optionally a positioning attachment for the exact positioning of the innermost part of the hearing device in the auditory canal on the inner end face.
  • the casting template and the positioning attachment are removed, as a result of which the hearing aid is essentially completed and can be worn immediately.
  • the problems which must be solved in particular in the development of said type of hearing aids are problems of miniaturization (in particular for appliances to be worn entirely in the ear canal, which have a diameter of less than 12 mm and a length of less than 25 mm) and Problems of safety of the casting process that should be practicable in the ear canal of the person who will be wearing the device (wearer).
  • the device should be in a substantially load-bearing condition, such that it can be handed over to the wearer without further processing or at most after a few simple manipulations.
  • it should also be able to meet conditions regarding functional adaptation to the needs of the wearer it should offer a high level of comfort and it should be able to be produced in an economically responsible framework.
  • the mentioned problems and wishes are addressed or fulfilled with the hearing aids according to the state of the art in various ways.
  • the devices according to the publications mentioned above meet the requirements of miniaturization, the minimal rework and the comfort.
  • the GiePrint in the distal (inner) area of the device is satisfactory.
  • the electronic components must be manipulated to fit the ear canal and are exposed to the casting process, which can damage them.
  • the molded body and the electronic components are firmly connected together in the finished device. In other words, if an electronic part is damaged by the casting process, if a faulty molding is cast in a casting process or if it is determined on the finished device that the selected electronics are not optimal for the wearer, the entire hearing aid must be replaced. The device can not be repaired. All of this has an economic burden.
  • the invention now has the object of providing a hearing aid to be worn at least partially in the auditory canal, which in a provisional state has a casting cavity and, in a definite state adapted to a specific auditory canal, a molded body having an individual shape cast in the casting cavity.
  • the hearing aid is intended to meet the abovementioned requirements with regard to miniaturization, safety, immediate availability, functional adaptability, wearing comfort, reparability and economy at least as well or better than known hearing aids of the same type. Furthermore, it is the object of the invention to provide a set and a method for producing the hearing device.
  • the hearing aid according to the invention consists in its provisional state of two or three elements (central and outer Giessraumelement and optionally separate channel element). In this state, it has no components serving the acoustic function (in particular no electronic components).
  • the two or three elements are connected by simply detachable connections, in particular positive snap connections. They define the casting cavity, give the provisional device sufficient stability for insertion into the ear canal, and are at least partially plastically deformable (bendable) for a first rough adaptation to the auditory canal.
  • the outer casting chamber element and optionally the separate channel element are removed from the molded body cast in the casting cavity, wherein the outer casting chamber element is replaced by a standardized, possibly limitedly deformable, electronic module.
  • the electronic module is attached using the same, releasable connection to the molding, as the remote, outer casting chamber element.
  • the hearing aid is not to be equipped for an acoustic function
  • another module takes the place of the electronic module, which has essentially the same shape as the electronic module, but which serves, for example, a passive protective function and is equipped accordingly.
  • the central G manraumelement has an inner and an outer ring, which are interconnected by a tubular, expandable membrane.
  • the diaphragm forms a surface of the device that can be adapted to an ear canal thanks to its expansibility, and the two rings essentially determine the shape of the inner and outer faces of the device.
  • the outer casting chamber element is matched in its shape to the outer ring of the central casting space element. It holds in the casting room essentially free the space for the electronic module and has an opening (pouring opening) for pressing the casting material and optionally a vent opening.
