摘要： A magnet assembly (100) for location around portions of bones in the middle ear comprises one portion (102) which is a magnet and another portion (104) which is a magnetic material, the portions being hinged to one another so that they are held around the bone by the magnetic field and are adapted for optimal coupling with a magnetic field produced by a coil in a magnetic induction hearing aid.
摘要翻译：用于定位在中耳部的骨头周围的磁体组件（100）包括作为磁体的一部分（102）和作为磁性材料的另一部分（104），所述部分彼此铰接以使其保持通过磁场围绕骨骼，并适于与由磁感应助听器中的线圈产生的磁场进行最佳耦合。

摘要： A magnetic induction hearing aid H where the microphone 20, the amplifying electronics 22, the battery 26 and a coil 28 are contained in a single housing 30 which is located deep in the ear canal 34. A magnet 32 is attached to portions of the middle ear by means of a malleus clip 60 or by implantation between the tympanic membrane 68 and the malleus 36. The magnet 32 is vibrated by interaction with the magnetic field produced by the coil 28. Two amplifier designs are disclosed for use with different levels of hearing loss. The magnet 32 can be coated with hydroxyapatite for permanent attachment to the body. The magnet 32 is coated with hydroxyapatite by an ion implantation process, a plasma spraying technique or a method of applying the hydroxyapatite while a precoating polymeric material has not fully solidified.

摘要翻译：一种磁感应助听器H，其中麦克风20，放大电子设备22，电池26和线圈28被容纳在位于耳道34深处的单个壳体30中。磁体32附接到中间部分通过马蹄形夹60或通过植入鼓膜68和肘骨36之间的植入来进行耳朵。磁体32通过与线圈28产生的磁场的相互作用而振动。两个放大器设计被公开用于不同听觉水平失利。磁体32可以涂覆羟基磷灰石，以永久性地附着到身体上。磁体32通过离子注入工艺，等离子体喷涂技术或在预涂聚合材料尚未完全固化的情况下施用羟基磷灰石的方法涂覆羟基磷灰石。
