    • A mechanically more stable and more complexly molded sound channel is to be provided for a hearing apparatus. Provision is made to this end for a sound channel, which has three sections in the longitudinal direction, the middle section of which has a different curvature or a larger internal circumference than the two outer sections, to be produced by injection molding. Here a negative of the sound channel is fixed within the injection molded form, with the negative consisting of a first material. The injection molded form with a second material, which has a higher melting point than the first material, is then extruded. The negative is then melted or burnt out of the cast sound channel. Very complex sound channel forms, for instance also with cavities and branching, can be realized in this way.
    • 要为听力设备提供机械上更稳定和更复杂的模制声音通道。 为此,为了通过注射成型产生的声道在纵向方向上具有三个部分,其中部具有与两个外部部分不同的曲率或更大的内圆周的声道。 这里,声音通道的负值固定在注射成型中,负极由第一种材料构成。 然后挤出具有比第一材料更高的熔点的第二材料的注射成型。 然后,消极的东西被熔化或烧毁了铸造的声道。 非常复杂的声音通道形式​​,例如也可以通过空腔和分支来实现。

    • A behind-the-ear hearing aid is provided, with an elongated housing and an audio shoe, which is affixed to an end face of the housing in such a way that it can be removed, and a coupling device, with which the audio shoe is coupled to the housing by a sliding movement parallel to the end face of the housing. In addition, affixed to the audio shoe there is a securing device which includes a slider which can be moved crossways relative to the direction in which the audio shoe slides, which in a first position permits the sliding movement of the audio shoe and in a second position prevents the sliding movement. It is thus possible to mount the audio shoe on the hearing aid housing, and to make any necessary contacts, with a double linear movement which is easy to realize.
    • 提供了一种耳后助听器,其具有细长的壳体和音频靴,其以可拆除的方式固定到壳体的端面,以及耦合装置,音频靴 通过平行于壳体的端面的滑动运动而联接到壳体。 另外,固定在音频靴上的固定装置包括一个可以相对于音频靴滑动的方向横穿运动的滑动件,该滑动件在第一位置允许音频鞋的滑动运动,并且在第二位置 位置防止滑动。 因此,可以将音频靴安装在助听器外壳上,并且以易于实现的双线性移动来进行任何必要的接触。
