20220248155 · 2022-08-04 ·

A hearing device has a housing in which a receiver is arranged as an electrical component. An antenna arrangement is formed, which has a winding in the form of a coil, which is arranged around the receiver with the interposition of a shielding foil. The shielding foil has a section extending around the receiver and several lugs adjoining it, which project beyond the receiver, the lugs enclosing between them an interspace adjoining the receiver. The shielding foil has in particular two layers, namely a magnetic layer and an electrical shielding layer. By this arrangement an antenna arrangement with high sensitivity is formed and at the same time a shielded partial area is created in the inter-space in which further components can be arranged. Due to the design of the lugs, which are particularly flexible, they can be attached to an inner wall of a housing.

An electromagnetic magnetic shielding material is used deflect electronic and electromagnetic radiation away from an electronic device. In this manner, the electromagnetic shielding material deflects the electronic and electromagnetic radiation from a user of the device to protect the user from any electronic and electromagnetic radiation produced by the electronic device. Additionally, because the electronic and electromagnetic radiation is deflected away from the user, rather than absorbed, a user is able to safely use the electronic device with less or no exposure to electronic and electromagnetic radiation.

Electronic device that limits electromagnetic emissions from multiple batteries

An electronic device, method, and computer program product enable limiting electromagnetic emissions from current between batteries.
