发明名称 Electromagnetic input transducers for middle ear sensing
摘要 A hearing assistance system senses sound vibrations of an auditory element in the middle ear and provides a stimulus to an auditory sensory element. The vibrations are received through the tympanic membrane, and sensed at the tympanic membrane, malleus, incus, or other auditory element. An electromagnetic sensor includes receiving and reference elements, e.g. a permanent magnet and a coil, having a time-varying magnetic flux linkage due to the vibrations. The magnet and coil are pivotably coupled to an auditory element and a carrier, or vice-versa, for self-alignment. A resulting electrical signal on the coil is processed, then provided to an output stimulator for mechanical or electrical stimulation of the cochlea.
