Patent attributes
A wireless charging hearing aid is disclosed, comprising a housing, an inner housing, a power management module, a circuit board and a control button. An electromagnetic induction technology is utilized in the disclosed to obtain an inductive current for charging a built-in battery. Elements within the housing do not need to be in contact with an external charging joint, the sealing of the housing is better, thereby achieving complete waterproofing and dustproofing, and improving the adaptability when using the disclosed. Besides, shapes and the number of layers of a receiving coil are flexibly designed according to requirements, and a magnetic conductive sheet is used to shield an inductive magnetic field to prevent the inductive magnetic field negatively influencing other elements. The elements within the housing can be arranged arbitrarily, which improves the flexibility in designing an overall appearance, and facilitates to incorporate artistic designs while reduces the design difficulties.
