    • 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.
    • 具有用于无线传输的传输设施的听觉设备将进一步小型化。 用于听力设备的传输设备,特别是具有包括电容器和线圈以及电线的振荡电路的听力设备设置在振荡电路中或其上,电线具有屏蔽。 电线包括具有信号线和屏蔽线的薄膜导体,其屏蔽电容并联连接到振荡电路的电容器。 屏蔽电容可以与电容器的电容一起以目标方式用作振荡电路电容。 以这种方式,将寄生屏蔽电容用作需要的电容。 由于薄膜导体的屏蔽电容仅受到最小的波动,所以只需要一个调谐电容器来调谐振荡电路。

    • The invention relates to a method for estimating an interference field for a real coil of a hearing apparatus comprising: simulating a field distribution of the interference field; calculating an interference field size for a number of coil segments of a virtual coil representing the real coil at a predetermined location and a predetermined orientation in the interference field; calculating an overall interference field size of the virtual coil with an individual, modifiable weight being applied to the interference field sizes of the coil segments; measuring a field size of the real coil at the predetermined location and the predetermined orientation; adapting the weights based on a comparison between the measured field size and the calculated overall interference field size for a rapid, calibrated estimation or calculation of the interference field.
    • 本发明涉及一种用于估计听力设备的实线圈的干扰场的方法,包括:模拟干扰场的场分布; 计算表示在预定位置处的实线圈的虚拟线圈的数量的线圈段的干涉场尺寸和干涉场中的预定取向; 计算虚拟线圈的总干扰场大小,其中单个可修改权重被施加到线圈段的干扰场尺寸; 测量预定位置处的实线圈的场尺寸和预定取向; 基于所测量的场大小与所计算的总干扰场大小之间的比较来适应所述权重,用于快速,校准的估计或干扰场的计算。
