摘要： A camera module of an electronic device includes a lens unit with a first coil, a vibration unit with a second coil, and a magnetic unit. The vibration unit is positioned outside the lens unit and spaces a first certain distance with the lens unit. The magnetic unit is positioned outside the vibration unit and spaces a second distance with the vibration unit. When the first coil receives electrical signal, the first coil is actuated to move with the lens unit. When the second coil receives electrical signal, the second coil is actuated to move with the vibration unit with the vibration unit. Therefore, the magnetic blocks are cooperated with the lens assembly and the vibration block, to make an automatic focusing function and a vibration function being combined in the camera module.

摘要： Provided is an input device that can reduce a magnetic attractive force generated between a coil-side yoke and magnets while suppressing the decrease in an operation reaction force that can be generated. The input device includes four coils arranged in a cross shape and a magnet assembly. When a current is applied to windings of the coils, electromagnetic forces are generated between the coils and the magnet assembly. In addition, the input device includes a coil-side yoke that is located opposite to the magnet assembly across the coils. The coil-side yoke is shaped so that magnetic fluxes generated by the magnet assembly are concentrated on winding portions of the windings of the coils, the winding portions being arranged along directions of a cross.
