20080232624 | Hearing device with current-conducting metal arm - The influence of interference from power supply lines in hearing devices is to be reduced. Thus a hearing device with an antenna for receiving and/or sending inductive signals, a signal processing device, to which the antenna is connected, a power supply unit for supplying power to the signal processing device and an electrical conductor for electrical connection of the power supply unit to the signal processing device is provided. The electrical conductor is L-shaped or U-shaped and closely follows the contours of the power supply unit. In addition the electrical conductor forms a part of an essentially round or rectangular ring, the axis of which has a main directional component perpendicular to the longitudinal axis of the antenna. A magnetic field created by the conductor is thus perpendicular to the antenna, so that its magnetic interference influence is reduced. | 09-25-2008 |

20090041278 | Hearing apparatus with adjusted components - To minimize an unusable free volume in a housing of a hearing apparatus, a hearing apparatus is proposed, which includes a housing, which has a predetermined form and at least one active, electronic component, which is arranged in the housing, with the component having a form, which is adjusted to the form of the housing and/or to the form of another component of the hearing apparatus. As a result, the unusable residual volume in the hearing apparatus can be minimized and a smaller form of the housing can in general thus be achieved. | 02-12-2009 |
20090274328 | APPARATUS AND METHOD FOR REDUCING INTERFERENCE EFFECTS IN THE CASE OF A WIRELESS DATA TRANSMISSION IN HEARING DEVICE APPLICATIONS - An apparatus and a method are provided for reducing an interference input coupling caused by asymmetrically embodied field lines of at least one hearing device component into a receiving antenna of a wireless data transmission facility of a hearing device. The apparatus includes at least one first means arranged in the hearing device, by means of which the asymmetry of the field lines is reduced and the field distortion is corrected. In addition, the receiving antenna can be geometrically adjusted to the outer interference field of the hearing device components such that interference currents induced in the antenna by means of field input coupling compensate. | 11-05-2009 |
20100195857 | HEARING AID WITH INTERFERENCE COMPENSATION AND METHOD FOR CONFIGURATING THE HEARING AID - For reducing the influence of interference fields on hearing aids, a hearing aid is provided with an electronic component into which a first and a second electromagnetic disturbance component can be injected by providing a predetermined electromagnetic interference field. The electrical component is formed asymmetric and/or a compensation component is arranged on the electrical component such that the first and the second interference components largely compensate for one another. A compensation plate or an element which is provided in any case, such as a microphone, may be used as the compensation component. If the electrical component is a coil, then its core may, for example, be conical or configured such that its winding density varies. | 08-05-2010 |
