Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device including a conductive housing,

The embodiments disclosed herein relate to an electronic device comprising a conductive housing and a non-conductive pattern.

BACKGROUND ART [0002] With the development of mobile communication technology, electronic devices such as smart phones and wearable devices are widely used. Such an electronic device may include various components in order to provide various functions (e.g., music reproduction, movie shooting, etc.). For example, an electronic device may include a graphics 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 components. The housing can house components between the front cover and the back cover of the housing to protect components from external impact. The front cover of the housing may be disposed on the front surface of the electronic device (the surface on which the display is exposed) to form the appearance of the electronic device. The front cover may include glass, a plastic injection molded product, a conductive member, and the like. The rear cover of the housing may be disposed on the back side of the electronic device to protect the components. The back cover may also include a plastic injection molded article, a conductive member, and the like.

If the back cover includes a conductive member, eddy current may occur in the back cover during wireless charging. The eddy current may be a current flowing in a region corresponding to the power receiving coil disposed inside the housing in the rear cover. 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. Therefore, the magnetic field formed by the eddy current can cancel the magnetic field formed by the power receiving coil.

When the intensity of the magnetic field formed by the power receiving coil is reduced, the amount of current flowing in the power receiving coil can be reduced. If the amount of current flowing in the power receiving coil is reduced, the power charged in the battery can also be reduced. Therefore, if an eddy current is generated in the rear cover, the wireless charging efficiency may be reduced.

If the back cover includes a conductive member, eddy currents can occur in the back cover even during wireless communication (e.g., 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, if an eddy current occurs during wireless communication, the communication efficiency may decrease.

The embodiments disclosed in this document can provide a method capable of reducing radio communication or wireless charging efficiency degradation using electromagnetic waves in an electronic device including a housing including a conductive member.

An electronic device according to an embodiment disclosed in this document includes a housing and a first coil disposed inside the housing, the housing including a front cover and a rear cover, wherein the rear cover is located at the center of the coil A hole disposed in a corresponding first region, a first slit extending in the hole, a second slit meeting with the first slit, and a second slit spaced apart from the first slit, And one end of the third slit may be located in a second region corresponding to the power receiving coil in the rear cover.

Referring to FIG. 1, the power supply 10 may include a power supply 12, a wireless charging integrated circuit 14, and a power transmission coil 16.

According to one embodiment, the power supply 12 can receive power from an adapter and deliver it to the wireless charging IC 14. The power supply unit 12 can adjust the amount of power to be transmitted to the wireless charging IC 14.

According to one embodiment, the wireless charging integrated circuit 14 may include a power amplifier (PA), a matching circuit, and a communication circuit. The PA can amplify the power received from the power supply unit 12 with a predetermined gain and output it to the matching circuit. The matching circuit can perform impedance matching. For example, the matching circuit may include one or more coils and capacitors, and may control impedance of the coils and capacitors to perform impedance matching. The matching circuit can increase the charging efficiency by performing impedance matching. The communication circuit may perform communication with a communication circuit included in the electronic device 100. [ For example, a communication circuit can perform bi-directional communication (Wi-Fi, ZigBee, BT / BLE) at a frequency of 2.4 GHz.

According to one embodiment, the power transmission coil 16 may transmit the power received via the wireless charging integrated circuit 14 to the power receiving coil 102. For example, the power transmission coil 16 may be powered by the power receiving coil 102 using a frequency of 100 to 205 KHz (WPC method), 277 to 357 KHz (PMA method), or 6.78 MHz (A4WP method) Lt; / RTI > According to one embodiment, the frequency band in which the power transmitting coil 16 transmits power to the power receiving coil 102 and the frequency band in which the communication circuit communicates may be the same (in-band) or different (out -band method).

The overvoltage prevention circuit may block the voltage applied to the battery 108 when the error information generated in the power supply device 10 is received through the communication circuit.

According to one embodiment, the charging circuit 106 may be disposed between the battery 108 and the wireless charging integrated circuit 104.

The charging circuit 106 may stop the charging of the battery 108 under the control of the over-voltage preventing circuit during charging.

According to one embodiment, the battery 108 can convert chemical and electrical energy in both directions. For example, the battery 108 may convert the electrical energy received by the power receiving coil 102 from the power supply 10 into chemical energy and store it. The electric energy received by the power receiving coil 102 from the power supply apparatus 10 may be rectified by the wireless charging integrated circuit 104 and transmitted to the battery 108.
