Definitions

  • the present invention relates to a hearing aid according to the preamble of claim 1 and an analog / digital converter module according to that of claim 4.
  • DE 195 457 60 proposes to combine the analog / digital converter on a hearing aid with the microphone arrangement to form a structural unit and to shield them together against electromagnetic interference.
  • the integral analog / digital converter must be taken into account with regard to the design of acoustic resonance rooms directly coupled to the microphone.
  • the microphone arrangement and the analog / digital converter are not only constructed in a modular manner and then combined in an inseparable manner, but it is also considered to releasably combine the two modules.
  • an analog / digital converter module according to the invention is proposed with at least two analog inputs, which differ Have input impedances and / or different signal gains.
  • Fig. La - ld schematic, the structure of a microphone / analog / digital converter arrangement according to the invention with different shielding concepts
  • Fig. 2 schematically and simplified, a sectional view through an example of an inventive
  • FIG. 1 a a microphone arrangement 1 is encapsulated against the effects of electromagnetic interference signals by means of a screen 3.
  • the analog / digital converter 5 is mounted on the screen 3 of the microphone arrangement 1.
  • a further screen 7 is provided on the output side of the analog / digital converter, in particular also to prevent electromagnetic interference from the output of the analog / digital converter back to its analog input.
  • FIG. 1c this is optimized in that the analog / digital converter 5 is encapsulated in a screen 7a.
  • the shield 7b of the analog / digital converter 5 is interrupted on one side and is completed there by that of the microphone arrangement 1.
  • the outer shape of the microphone arrangement or its screen 3 there is a dependency between the outer shape of the microphone arrangement or its screen 3 and the design of the analog / digital converter 5.
  • 2 shows schematically and for example the structure of the combination of microphone arrangement and analog / digital converter according to the invention.
  • the shield housing 13 of the microphone arrangement 10 with acoustic input 11 carries a flexible, conductor track-coated film 15 with conductor tracks 17 of the converter digital output.
  • the analog / digital converter 16 is encapsulated with a thin screen 17, which, as shown at 17 c , completes and metallizes the potential of the screen housing 13 via a metallization layer of the film 15. As shown only schematically, the analog / digital converter is constructed within the screen 17. As shown only schematically, its analog input
  • the analog / digital converter used according to the invention can in principle be used with different input configurations. It has at least two inputs Ei and E 2 with different input impedances Zi and Z 2 and / or with different input amplifications Gi and G 2 , possibly even with different analog / digital converter characteristics. This enables the analog / digital converter to be used in a modular, flexible manner for different microphone arrangements.
