Problems solved by technology
[0002] With the popularization and use of Bluetooth headsets, users have higher requirements for user experience. True wireless noise-canceling headsets require that the battery has no magnetic field interference, otherwise it will affect the magnetic field of the headset, and the mutual interference between the two will affect the user experience.
Secondly, the customer has stricter requirements on the height of the battery, which needs to be as thin as possible. The existing button-type steel shell battery is mostly a wound structure, and the pole piece cannot be made more thin due to the limitation of slitting, sheet production, and winding. Narrow, the height of the battery cannot be less than 3.0mm, which cannot meet the needs of the whole machine structure; the winding structure will generate a rotating current along the winding direction during the battery discharge process, and the rotating current will generate an axial magnetic field, which will affect the Headphones generate magnetic interference, affecting user experience
