Publication number: 20120219166Abstract: A floating mass transducer for a hearing implant includes a cylindrical transducer housing that is attachable to a middle ear hearing structure and that has an outer surface with one or more electric drive coils thereon. A cylindrical transducer magnet arrangement is positioned within an interior volume of the transducer housing and includes a magnetic pair of an inner rod magnet and an outer annular magnet. Current flow through the drive coils creates a coil magnetic field that interacts with the magnetic fields of the transducer magnet arrangement to create vibration in the transducer magnet which is coupled by the transducer housing to the middle ear hearing structure for perception as sound. Opposing magnetic fields of the transducer magnet arrangement cancel each other to minimize their combined magnetic field and thereby minimize magnetic interaction of the transducer magnet arrangement with any external magnetic field.Type: ApplicationFiled: February 23, 2012Publication date: August 30, 2012Applicant: Vibrant Med-El Hearing Technology GmbHInventor: Geoffrey R.

Publication number: 20090253951Abstract: A floating mass transducer for assisting hearing in a person is provided. Inertial vibration in the floating mass transducer (100) produces vibrations in the inner ear. In an exemplary embodiment, the floating mass transducer comprises a magnet assembly (12) and a coil (14) secured inside a housing (10) which is attached to bone within the middle ear. The coil is more rigidly secured to the housing than the magnet. The magnet assembly and coil are configured such that conducting alternating electrical current through the coil results in vibration of the magnet assembly and coil relative to one another. The vibration is caused by the interaction of the magnetic fields of the magnet assembly and coil. Because the coil is more rigidly secured to the housing than the magnet assembly, the vibrations of the coil cause the housing to vibrate. The floating mass transducer may generate vibrations in the inner ear by being attached to the skull or through a mouthpiece.Type: ApplicationFiled: June 18, 2009Publication date: October 8, 2009Applicant: VIBRANT MED-EL HEARING TECHNOLOGY GMBHInventors: Geoffrey R.
