Abstract: A wearable audio device sized to fit within an ear of an user comprises an outer housing; a circuit board positioned within the outer housing; a battery having an anode and a cathode, the battery being connected to the circuit board; a speaker adjacent the battery; and an electromagnetic interference (“EMI”) shield tab coupled to the anode. The EMI shield tab may be configured to shield the speaker from EMI generated by the circuit board and to provide an electrical interconnection to the anode. The EMI shield tab may be comprised of a high magnetic flux permeable metal material

Abstract: The present disclosure provides for an arrangement of components within a hearable device, such as earbuds, to reduce H field coupling for E noise improvement. A battery is positioned above a magnet and speaker, such that the battery is not coaxially aligned with either the magnet or the speaker. An internal positive tab of a battery is positioned farthest from a speaker yoke, while an internal negative tab of the battery is closer to the speaker yoke. Magnetic flux poles of a contact magnet have different contributions for electric field coupling.
