HEARING DEVICE
20210152958 · 2021-05-20 ·

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.

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. A first battery is positioned proximal to an earpiece speaker within the electronic device. At least one second battery is positioned at a different location within the electronic device that is not proximal to the earpiece speaker. A controller is electrically connected to a switch that is electrically connected in-line with the first battery. The controller selectively toggles the switch between first and second switches state. The controller initiates activation of a first software mode of the electronic device corresponding to operation of the earpiece speaker. In response to detecting the activation, the controller toggles the switch to the first switch state in which the switch limits current drawn from the first battery while the electronic device is in the first software mode, thus reducing baseband electromagnetic emissions emanating from the first battery.
