A mobile terminal is provided, which includes a wireless charging module, a battery pack, and a circuit board substrate. The wireless charging module includes a charging coil formed of a wound conducting wire and a communication coil placed adjacent to the charging coil. The wireless charging module has a substantially planar shape. The battery pack has a substantially planar shape and is configured to store power from the wireless charging module. The circuit board substrate is configured to control operation of the mobile terminal. The wireless charging module overlaps with each of the circuit board substrate and the battery pack.

Electronic device including non-contact charging module and battery

A mobile terminal is provided with a housing, a circuit board included in the housing and having a thickness direction normal to a plane of the circuit board, a battery pack included in the housing, and a non-contact charging module included in the housing. The non-contact charging module includes a charging coil formed of a wound conducting wire; a communication coil arranged adjacent to the charging coil; and a magnetic sheet on which the charging coil and the communication coil are arranged. The magnetic sheet has four edges that collectively define a rectangular profile of the magnetic sheet, and at most three pairs of adjacent edges respectively meet to form at most three corners. At least a portion of the non-contact charging module overlaps with the circuit board as viewed in the thickness direction of the circuit board.

Mobile terminal and chargeable communication module

A mobile terminal is provided with a housing having a rectangular shape in a plan view of the housing defined by two short sides along a lateral direction and two long sides along a longitudinal direction. A camera, a battery, and a circuit board are included in the housing. A wireless charging coil is arranged in the housing and includes a winding portion and two leg portions. A sheet is arranged in the housing. The sheet has a rectangular shape including four edges and four corner portions, wherein each pair of adjacent edges forms a virtual corner, each corner portion is receded inwardly from its corresponding virtual corner by a receding distance, and one of four receding distances is greater than other three of the four receding distances.

Mobile terminal including wireless charging coil and magnetic sheet having inwardly receding portion

This communication apparatus makes it possible to have a non-contact charging module and a sheet antenna coexist, even in the case where there the non-contact charging module and the sheet antenna in the communication apparatus. The apparatus is provided with: a housing; a secondary-side non-contact charging module, which is housed in the housing, receives power by means of electromagnetic induction, and has a first coil having a conducting wire wound thereon, and a first magnetic sheet facing the first coil; and an NFC antenna, which is housed in the housing, and has a second coil having a conducting wire wound thereon, and a second magnetic sheet facing the second coil. The secondary-side non-contact charging module and the NFC antenna are not laminated to each other.

Electronic device including non-contact charging module

Provided is a non-contact charging module wherein adverse effects from magnets have been prevented even where magnets are used for positioning, power transmission efficiency has been improved, and the entire module has been made thin due to a state of improved power transmission efficiency. The non-contact charging module comprises a planar coil portion () of spirally wound conductive wiring, and a magnetic sheet () that is provided so as to oppose a surface of a coil () on the planar coil portion (), and is characterized in that the magnetic sheet is layered with a first layer, and a second layer that has a lower magnetic permeability and a higher saturation magnetic flux density than the first layer.

Non-contact charging module having a wireless charging coil and a magnetic sheet

This non-contact charging module can be suitably used by suppressing a change of an L value of a coil that is provided in the non-contact charging module, and achieves size reduction, even in the cases where a magnet that is provided in the other non-contact charging module is used or not used. The module is characterized in that: the module is provided with a primary side coil (a) wherein a conducting line is wound in a substantially rectangular shape, and a magnetic sheet () that is provided with a surface on which the primary side coil (a) is placed; and that a substantially rectangular-shaped hollow portion of the primary side coil (a) has the short side thereof shorter than the diameter of a circular magnet (a), and the long side thereof longer than the diameter of the circular magnet (a).

Non-contact charging module, electronic apparatus, and non-contact charging apparatus

A chargeable communication module is provided, which includes a wireless power charging coil; first and second wireless communication coils, which are respectively electrically isolated from the wireless power charging coil; and a magnetic sheet. The wireless power charging coil is disposed on a surface of the magnetic sheet. The first and second wireless communication coils are adjacent to and outside of the wireless power charging coil. At least a portion of the first wireless communication coil is disposed on the surface of the magnetic sheet. At least a portion of the second wireless communication coil is disposed on the surface of the magnetic sheet.
