Patent number: 7322930Abstract: Implantable microphone devices that may be utilized in hearing systems are provided. An implantable microphone device allows the implantable microphone's frequency response and sensitivity to be selected. A microphone device with an increased membrane flexibility and a decreased acoustic compliance of the sealed cavity. Vibrations of a membrane are transmitted through a primary air cavity and through an aperture of a microphone. Keeping a flexible membrane and decreasing the sealed air cavity compliance are the preferred way to simultaneously increase overall sensitivity of the device, and move the resonance peak to higher frequencies.Type: GrantFiled: August 5, 2003Date of Patent: January 29, 2008Assignee: Vibrant Med-El Hearing Technology, GmbHInventors: Eric M. Jaeger, Geoffrey R. Ball, Duane E. Tumlinson

Patent number: 6676592Abstract: A dual coil floating mass transducer for assisting a person's hearing is provided. Inertial vibration of the housing of the floating mass transducer produces vibrations in the inner ear. A magnet is disposed within the housing biased by silicone springs so that friction is reduced between the magnet and the interior surface of the housing. Two coils reside within grooves in the exterior of the housing which cause the magnet to vibrate when an electrical signal is applied to the coils.Type: GrantFiled: November 1, 2002Date of Patent: January 13, 2004Assignee: Symphonix Devices, Inc.Inventors: Geoffrey R.

Publication number: 20010003788Abstract: A floating mass transducer for improving hearing in a hearing impaired person is provided. The floating mass transducer (100) may be implanted or mounted externally for producing-vibrations in a vibratory structure of an 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 fixed to an ossicle of a 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 vibrations of the housing are conducted to the oval window of the ear via the ossicles.Type: ApplicationFiled: November 30, 2000Publication date: June 14, 2001Inventors: Geoffrey R. Ball, James M. Culp, Craig Mar, Tim Dietz, John D. Salisbury

Patent number: 6139488Abstract: An implantable hearing device is coupled to a tympanic membrane and an oval window of a human subject's ear. The implantable hearing device includes an amplifier, a first transducer electrically coupled to the amplifier, and a second transducer also electrically coupled to the amplifier. A first compliant connecting member elastically couples the tympanic membrane to the first transducer. A second compliant connecting member elastically couples the second transducer to the oval window. Ambient sounds are transmitted from the tympanic membrane to the first transducer by the first compliant connecting member, thus generating an audio signal. The audio signal is amplified by the amplifier, which drives the second transducer. The second compliant connecting member transmits the amplified sounds to the oval window, possibly via one or more ossicles or prostheses. The hearing of the human subject is thus improved.Type: GrantFiled: September 1, 1998Date of Patent: October 31, 2000Assignee: Symphonix Devices, Inc.Inventor: Geoffrey R. Ball

Patent number: 5913815Abstract: 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: GrantFiled: December 6, 1995Date of Patent: June 22, 1999Assignee: Symphonix Devices, Inc.Inventors: Geoffrey R.
