Method to reduce H-field coupling for E-noise and a kind of non-coaxial integrated earbuds
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.
1. A hearable device, comprising:
a housing;
a battery within the housing, the battery having an internal positive tab and an internal negative tab;
a contact magnet within the housing, the contact magnet positioned beneath the internal negative tab of the battery; and
a speaker within the housing and positioned beneath the internal positive tab of the battery.
2. The hearable device of claim 1 , wherein the speaker comprises a yoke having a North pole and a South pole, the North pole being oriented adjacent a bottom surface of the battery.
3. The hearable device of claim 1 , the contact magnet having a North pole and a South pole, the South pole being oriented adjacent a bottom surface of the battery.
4. The hearable device of claim 1 , wherein the contact magnet has a triangular cross section.
5. The hearable device of claim 1 , wherein the contact magnet is laterally adjacent to the speaker.
6. The hearable device of claim 1 , wherein the hearable device is an earbud.
7. The hearable device of claim 1 , wherein a central axis through the battery is separated from a central axis through the speaker by a lateral distance d, the distance d being greater than 0.
8. The hearable device of claim 7 , wherein the distance d is less than or equal to half a diameter of the battery.
9. A hearable device, comprising:
a housing;
a battery within the housing, the battery having a top surface and a bottom surface;
a contact magnet within the housing, the contact magnet positioned beneath the battery, the contact magnet having a North pole and a South pole, the contact magnet being oriented such that the South pole is adjacent the bottom surface of the battery; and
a speaker within the housing and positioned beneath the battery, the speaker comprising a yoke having a North pole and a South pole, the yoke oriented such that a North pole of the yoke is adjacent the bottom surface of the battery.
10. The hearable device of claim 9 , wherein the battery has an internal positive tab and an internal negative tab.
11. The hearable device of claim 9 , wherein the internal positive tab is oriented above the speaker yoke.
12. The hearable device of claim 9 , wherein the internal negative tab is oriented above the contact magnet.
13. The hearable device of claim 9 , wherein the internal negative tab is positioned at least a predetermined distance from the speaker yoke.
14. The hearable device of claim 9 , wherein the internal positive tab of the battery is positioned closer to the speaker yoke than the internal negative tab of the battery.
15. A hearable device, comprising:
a housing;
a battery within the housing, the battery having a central battery axis;
a contact magnet within the housing, the contact magnet positioned beneath the battery; and
a speaker within the housing positioned laterally adjacent to the contact magnet, the speaker having a central speaker axis;
wherein the central battery axis is separated from the central speaker axis by at least a predetermined distance d.
16. The hearable device of claim 15 , wherein the battery has an internal positive tab and an internal negative tab.
17. The hearable device of claim 16 , wherein the speaker comprises a speaker yoke and wherein the internal positive tab is oriented above the speaker yoke.
18. The hearable device of claim 16 , wherein the internal negative tab is oriented above the contact magnet.
19. The hearable device of claim 16 , wherein:
the contact magnet has a South pole;
the speaker comprises a speaker yoke having a North pole and a South pole; and
the South pole of the contact magnet is positioned adjacent the battery beneath the internal negative tab, and the North pole of the speaker yoke is positioned adjacent the battery beneath the internal positive tab.
20. The hearable device of claim 15 , wherein the contact magnet has a triangular cross section.
