  • the protective device 90 ensures that the hearing aid 1 can only be operated when the circlip 30 is correctly mounted on the support stub 27.
  • the protective device 90 comprises a ring-side contact element 91 which is attached to the retaining ring 30, and a housing-side electrical interruption 92, which is arranged on the housing shell 15, specifically at a peripheral edge of the opening 21.
  • the ring-side contact element 91 is embodied, for example, as a conductive ring on an end face of the securing ring 30 facing the housing shell 15.
  • the housing-side interruption 92 interrupts a circuit which serves to supply power or the hearing aid 1. If the retaining ring 30 is tightened sufficiently firmly, the interruption 92 is bridged by the contact element 91 and the circuit is closed. This ensures that the hearing aid 1 can only be operated when the circlip 30 is properly mounted on the support stub 27.
  • the protective device 90 comprises a mechanical coupling 95 which mechanically couples the securing ring 30 to a locking mechanism 96 assigned to the battery flap 76.
  • the coupling 95 and the locking mechanism 96 are indicated here only symbolically.
  • the mechanical coupling 95 releases the locking mechanism 96 only when the locking ring 30 is correctly mounted on the support stub 27. Otherwise, the battery door 76 is blocked by the lock mechanism 96 so that it can not be closed.
  • the battery door 76 is open, however, again a circuit that ensures the power supply of the hearing aid 1, interrupted, and the hearing aid 1 can not be operated.
  • the user is caused to check the correct fit of the locking ring 30 when the hearing aid 1 is not functioning properly.
  • the contact element 91 and the interruption 92 serve to use the securing ring 30 as an on / off switch for the hearing aid 1.
  • the locking ring 30 thus comes as an additional function to a switching function.
  • the securing ring 30 is not screwed onto the holding stubs 27, but plugged with a click connection, so that the securing ring 30 is rotatably mounted.
  • the contact element 91 bridges the interruption 92 only in a certain rotational position of the securing ring 30. (The contact element 91 extends in this case only over a certain peripheral portion of the securing ring 30.)
  • the retaining ring 30 is used as an operating element for changing between different hearing device modes, etc.
  • the switching function of the locking ring 30 is, for example, by an injection-molded circuit carrier ("Molded Interconnect Device", short MID) or by a reed switch (also reed contact) -. by a switch actuated by a magnetic field - implemented.
  • Fig. 6 shows the locking ring 30 in an alternative embodiment, which largely corresponds to the preceding embodiments.
  • the connecting element 35 is arranged on the securing ring 30 here.
  • the connecting element 35 is also designed substantially analogously to the above embodiments and has, in particular, the ball joint head 52. When the securing ring 30 is screwed on, the connecting element 35 is aligned with the sound channel 62 (as in FIG Fig. 1 shown).
  • the connecting element 35 is made of metal and embedded in an injection molding process in the - made of plastic - locking ring 30.
  • connecting element 35 and securing ring 30 are produced in one piece (monolithic), for example as an injection molded part made of plastic or as a turned part made of metal.
  • a cerumen filter is integrated in the securing ring 30 (not shown here), which prevents penetration of dirt, in particular cerumen (earwax) into the sound channel 62.
