Definitions

  • the present invention relates to a hearing aid according to the preamble of claim 1 and a method for producing a hearing aid according to the preamble of claim 9.
  • Hearing aids are extremely complex systems. In order to meet the respective needs of the consumer, it is necessary to provide a large number of different hardware configuration variants. This results in an extremely cost-effective variety for production as well as for sales and hearing aid adaptation, for example by A large number of different device configurations have to be created in production, appropriately labeled and checked, a corresponding stockkeeping is required in sales and other procedures have to be selected when adapting the device to the individual needs of the customer, depending on the device configuration.
  • the object of the present invention to solve this problem on the basis of a hearing aid of the type mentioned at the beginning.
  • the peripheral units are provided with an identification unit, the output of which is operatively connected to the input of a comparison unit.

  • the comparison unit acts on a configuration memory unit.
  • peripheral units Because at least a part, preferably all peripheral units identify themselves, and the comparison unit according to the reported identifications from the peripheral units, after comparison with several possibilities, peripheral units switch on, the existing hardware configuration saves the following notable advantages:
  • the output of the comparison unit is operatively connected to an operating selection input on the signal processing unit.
  • This enables only processing to be permitted on the signal processing unit, be it for operation as such or to be implemented already, which are also permitted in the actual system configuration.
  • Operating programs that e.g. To be implemented wirelessly via a transceiver, it can be checked for admissibility with regard to the prevailing system constellation.
  • the operative connection between peripheral units and the central signal processing unit is established via a bus and via interface units.
  • the central digital signal processing unit is connected in terms of hardware to the peripheral units provided in each case. that must be. The more options regarding the peripheral unit are provided, the more connections have to be provided for the central signal processing unit. This number dominates more and more the necessary chip area for the signal processing unit mentioned, which is particularly disadvantageous in the miniaturization aimed at in the hearing aid sector.
  • peripheral units can be largely used in audio signal components e.g. Sensors, actuators, amplifiers, filters, etc. on the one hand control components e.g. Subdivide transceivers, selector switches, memory etc.

  • the signal processing unit / bus / peripheral units can also be connected via other interface units, e.g. via AES-3 interface units from Audio Engineering Society and / or SPI interface units from Motorola.
  • the actual configuration also determines which signals are transmitted to the central signal processing unit and therefore which control parameters. If the peripheral units are automatically identified on the hearing aid according to the invention, this also opens up the possibility of automatically activating the prevailing configuration with peripheral units from a plurality of possible signal processing configurations, or e.g. to be implemented externally, e.g. via a transceiver, i.e. wireless. This also eliminates the problem that signal processing processes are implemented on a hearing aid that do not correspond to the present configuration with peripheral units.
