Abstract
A speaker assembly includes a magnetic field counteracting component arranged on an end face of an audio component facing a battery with positive and negative electrode tabs. When a counteracting current into a conductor forms a counteracting magnetic field acting on the audio component, the counteracting magnetic field counteracts an interfering magnetic field acting by the battery on the audio component. The conductor includes a first end and a second end such that, in a thickness direction of the battery, the first end corresponds to a position of a positive electrode tab and the second end corresponds to a position of a negative electrode tab.
