Metal frame for device being equipped with wireless charging transmitter or receiver

Abstract

Disclosed herein is a metal frame for a device being equipped with a wireless charging transmitter or receiver including a plurality of perforation holes configured in at least one partial area of the metal frame, wherein the perforation hole has a diameter ranging from sub nm to several μm, and wherein an average distance between an arbitrary point A on a circumferential surface of a perforation hole, among the plurality of perforation holes, and an arbitrary point B on a circumferential surface of another perforation hole being adjacent to the perforation hole is equal to or less than a skin depth corresponding to a metallic material of the metal frame, and wherein point A and point B respectively correspond to points indicating a longest distance between the circumferential surfaces of each perforation hole to which point A and point B belong.

Accordingly, the metal frame is expected to perform wireless charging by including at least a wireless charging receiver, i.e., enabling wireless charging to be carried out smoothly despite equipping a mobile device with a metal frame for its outer feature instead of a plastic frame, wherein the metal frame provides an excellent texture of premium quality and outstanding durability as compared to the plastic frame.

Benefits of technology

[0014]A technical object of the present invention is to provide a metal frame for a device being equipped with a wireless charging transmitter or receiver capable of performing wireless charging by including at least a wireless charging receiver, i.e., enabling wireless charging to be carried out smoothly despite, for example, a mobile device having its outer feature equipped with a metal frame instead of a plastic frame, wherein the metal frame provid

Problems solved by technology

Therefore, it has become more difficult for the manufacturers to create their own distinguished functions that are related to the performance of the device.

Accordingly, the manufacturers are becoming more focused on the design of their mobile devices, and, therefore, the selection of the material for a frame configuring the outside feature of the mobile device has become one of the most important issues.

However, due to the characteristics of the plastic material, there were limitations in realizing high-quality texture in the mobile devices.

Evidently, metal frames may be disadvantageous in the aspect of weight as compared to the plastic frames.

However, due to the exc
