摘要：An implantable floating mass transducer is described for a hearing implantsystem in an implant patient. A cylindrical transducer housing contains a cylindrical innermass magnet having an inner magnetic field with a first field direction. One or more signal
drive coils are on the outer housing surface for conducting a transducer drive signalcurrent to produce a signal magnetic field that interacts with the inner magnetic field tocreate vibration of the inner mass magnet which is coupled by the transducer housing tothe internal hearing structure for sound perception by the implant patient. A ring-shapeouter offset magnet is positioned around the outer housing surface with an outermagnetic field having a second field direction opposite to the first field direction so as tooffset the inner magnetic field to minimize their combined magnetic field and therebyminimize magnetic interaction of the transducer with any external magnetic field.
