Abstract:
The hearing device (1) comprises an outer part (2) to be worn behind a hearing device user's ear (5), an inner part (3) to be worn within the hearing device user's ear (5), and a connecting portion (12) operationally interconnecting said outer part (2) and said inner part (3). An output transducer (8) is comprised in said outer part (2) or in said connecting portion (12). Said inner part (3) comprises an input transducer (6) and, operationally interconnected between said input transducer (6) and said output transducer (8), a signal processing unit (7). Preferably, said connecting portion (12) is detachably connected to said outer part (2) or to said inner part (3) or to both, said outer part (2) and said inner part (3). The connecting portion (12) comprises a tube member (23) for providing guidance for acoustic sound (10) outputted from said output transducer (8) to said inner part (3). Preferably, a wired electrical connection (13) is integrated in said tube member (23), wherein via said wired electrical connection (13), electrical energy is transferred from the outer (2) to the inner (3) part, and wherein signals and data are transmitted via said wired electrical connection (13), preferably using a bus system. The wired electrical connection (13) may furthermore serve as an antenna (22).
