Description

Electronic Device for Including Conductive Housing

Embodiments disclosed in this document relate to an electronic device including a conductive housing and a non-conductive pattern.

BACKGROUND With the development of mobile communication technology, electronic devices such as smartphones and wearable devices are widely spread. These electronic devices may include several parts in order to provide various functions (eg, music playback, video recording, etc.). For example, an electronic device may include a graphic processing unit (GPU) to provide a graphical user interface (GUI) through a display module.

The electronic device may include a housing for protecting the above-described parts. The housing may protect the components from external impact by accommodating components between the front cover and the rear cover of the housing. The front cover of the housing may be disposed on the front surface of the electronic device (a surface on which the display is exposed) to form the appearance of the electronic device. The front cover may include glass, plastic injection molding, or a conductive member. A rear cover of the housing may be disposed on a rear surface of the electronic device to protect components. The rear cover may also include a plastic injection molding, a conductive member, and the like.

If the rear cover includes a conductive member, eddy current may occur in the rear cover during wireless charging. The eddy current may be a current flowing in a region of the rear cover corresponding to the power receiving coil disposed inside the housing. The direction of the eddy current may be opposite to the direction of the current flowing in the power receiving coil. Since the direction of the eddy current is opposite to the direction of the current flowing in the power receiving coil, the direction of the magnetic field formed by the eddy current may also be opposite to the direction of the magnetic field formed by the power receiving coil. Accordingly, the magnetic field formed by the eddy current may cancel the magnetic field formed by the power receiving coil.

When the intensity of the magnetic field formed by the power reception coil decreases, the amount of current flowing through the power reception coil may decrease. When the amount of current flowing through the power receiving coil decreases, the power charged in the battery may also decrease. Therefore, when eddy currents occur in the rear cover, wireless charging efficiency may decrease.

If the rear cover includes a conductive member, eddy currents may occur in the rear cover even during wireless communication (eg, NFC, MST). Since the eddy current is opposite to the direction of the current flowing in the communication coil, the magnetic field formed by the eddy current can cancel the magnetic field formed by the communication coil. Therefore, when eddy currents occur during wireless communication, communication efficiency may decrease.
