| 20080292125 | Method and an Arrangement for Damping a Resonance Frequency - A method and an arrangement for damping the resonance frequency in a vibrator for bone anchored hearing aids in which sound information is mechanically transmitted via the skull bone directly to the inner ear of a person with impaired hearing. A microphone picks up the sound, a signal processor amplifies and filters the signal from the microphone and a vibrator converts the electrical signal into vibrations. The signal processor of the hearing aid is used for damping the resonance frequency peak of the vibrator. For this purpose the signal processor includes electronic filters that are arranged to reduce the amplification in the signal processing chain of the hearing aid as much as the desired dampening of the resonance frequency peak of the vibrator. | 11-27-2008 |
| 20080319250 | Vibrator - An electromagnetic vibrator for generating vibrations in bone conducting hearing aid devices. The vibrator includes a magnetic device, a vibrator plate and an inner spring member providing an air-gap between the magnetic device and the vibrator plate. The vibrator is housed in a casing and an outer spring is arranged between the vibrator and the casing to isolate movements of the magnetic device relative to the casing. The outer spring is part of the surrounding casing and is mechanically attached to the vibratory transmitting element via an elastic sealing element. The sealing function of the hearing aid housing is provided by the outer spring attachment. | 12-25-2008 |
| 20100209873 | ANCHORING ELEMENT - Aspects of the present invention are generally directed to an anchoring element comprising a screw shaped central part, a flange which functions as a stop when the anchoring element is installed into the skull bone, and a tubular peripheral part which is connected to the central part via said flange, wherein the peripheral part together with the central part is arranged to cut into the bone tissue when the anchoring element is installed into the bone tissue. | 08-19-2010 |
| 20100298626 | BONE CONDUCTION DEVICE HAVING A MULTILAYER PIEZOELECTRIC ELEMENT - A bone conduction device comprising a multilayer piezoelectric element. The multilayer piezoelectric element comprises two stacked piezoelectric layers, and a flexible passive layer disposed between the piezoelectric layers. The device also comprises a mass component attached to the multilayer piezoelectric element; and a coupling attached to the multilayer piezoelectric element configured to transfer mechanical forces generated by the multilayer piezoelectric element and the mass component to a recipient's skull. | 11-25-2010 |
