Abstract:
1. A hearing apparatus, comprising: a housing; and a receiver device removably electrically coupled to the housing, the receiver device having an electronic identification element configured to identify during an identification procedure an electrical characteristic of a receiver connected to an electrical cable assembly comprising a first actuation-signal cable, a second actuation-signal cable and a bi-functional, electrically conductive sheath cable, the sheath cable and the electronic identification element connected into the housing via a common single-pole connection, wherein the sheath cable is physically arranged about the first and second cables to electromagnetically shield the first and second cables from electromagnetic interference during normal operation of the hearing apparatus, wherein the electromagnetic shield provided by the sheath cable during the normal operation of the hearing apparatus constitutes a first function provided by the sheath cable, wherein the sheath cable is further arranged to electrically carry during the identification procedure an electrical measurement effective to identify the electrical characteristic of the receiver, wherein electrically-carrying said electrical measurement during the identification procedure constitutes a second function provided by the sheath cable.
