    • The invention relates to a hearing aid with a housing, a receiver disposed outside the housing and a transparent hearing tube to connect the receiver to the housing. At least one electrical line made of transparent, conductive polymer is provided in the hearing tube to connect the receiver electrically to an electronic signal processor disposed in the housing and at least one electrical insulator made of transparent, non-conductive polymer. A number of lines and insulators are advantageously disposed coaxially. The outer line is advantageously grounded. The impedance of the receiver and impedance of an amplifier output stage being part of the electronic signal processor and connected to the at least one line and the surface area of the line are advantageously tailored to one another so that the power transmission of the line is at a maximum. The hearing tube is completely transparent despite the electrical lines provided therein.
    • 本发明涉及一种具有壳体的助听器,设置在壳体外部的接收器和用于将接收器连接到壳体的透明听筒。 由透明导电聚合物制成的至少一条电线设置在听力管中,以将接收器电连接到设置在壳体中的电子信号处理器和由透明非导电聚合物制成的至少一个电绝缘体。 多个线和绝缘体有利地同轴地布置。 外线有利地接地。 接收器的阻抗和作为电子信号处理器的一部分并且连接到线路的至少一个线路和线路的表面区域的放大器输出级的阻抗有利地相互适应,使得线路的功率传输在 最大。 尽管其中提供电线,听力管是完全透明的。
