Abstract
A hearing aid device having a telecoil and a power consuming element is disclosed. The hearing aid device further comprises an at least partial loop in the power supply line, which at least partial loop provides a magnetic signal that at least attenuates or cancels noise induced from the power draw of the power consuming component.
Claims18
A hearing aid device comprising:
- a housing configured to be positioned in, on or at an ear of a user,
- a power source arranged in the housing, a power connector configured to establish electrical contact with the power source, the power connector extending along a first power connector axis,
- a first power consuming component arranged on a first substrate, the first substrate arranged in the housing, the first power consuming component powered by said power source via said power connector,
- a noise sensitive component arranged in the housing at a distance from said first power consuming component, the noise sensitive component being sensitive to electromagnetic radiation, and
- a conductive supply line extending between the power connector and the first power consuming component,
- wherein a part of the conductive supply line has a geometry as at least part of a loop, and
- wherein the part of the conductive supply line is configured to emit a second magnetic field in response to the first power consuming component drawing power from the power source, so that a magnetic field originating from the power connector, due to the power draw, is at least reduced at the noise sensitive component by the second magnetic field.
