Abstract:
Hearing apparatuses with transmission facilities for the wireless transmission are to be miniaturized further. A transmission facility for a hearing apparatus and in particular a hearing device with an oscillating circuit including a capacitor and a coil as well as an electrical line is provided in or to the oscillating circuit, with the electrical line having a shielding. The electrical line includes a film conductor with a signal line and shielding line, the shielding capacitance of which is connected in parallel to the capacitor of the oscillating circuit. The shielding capacitance can be used together with the capacitance of the capacitor in a targeted fashion as an oscillating circuit capacitance. In this way, the parasitic shielding capacitance is used as a wanted capacitance. As the shielding capacitance of the film conductor is only subjected to minimal fluctuations, it only requires a small tuning capacitor for tuning the oscillating circuit.
