摘要：A digital communication device such as a hearing aid or a headset has a powersupply, a signal processing device, means for receiving a wireless signal and a receiver orloudspeaker which produces an audio signal based on a modulated pulsed signal withhigh frequency shifting rate produced by the signal processing device. The receiver also
has a first and a second connection point for receiving the pulsed modulated signalwherein the sound-producing parts of the receiver are at least partially enclosed by ametal box, and a third connection point is provided which is in electrical contact with themetal of the metal box. The third connection point is connected to the electric circuitry ofthe communication device at a point having a stable and well defined electrical potential.In this way the electro- and magnetic radiation from the metal parts of the receiver isreduced.
