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.

Abstract: A hybrid ANC system that can allow a feedback microphone to receive the same external noise as a feedforward microphone. A processor can generate an anti-noise signal based on what both microphones received to cancel a broader range of frequencies of the external noise.
