Embodiment Construction

[0013] Please refer to figure 2 , the mobile phone (hereinafter referred to as mobile phone) that the present invention has metal hinge can be the mobile phone of various structures, as bar mobile phone, clamshell mobile phone and sliding cover mobile phone. The mobile phone includes a main board 1 , a metal hinge 6 , a connector 7 and a conductive foam 9 , and in this embodiment, the components irrelevant to the present invention are not shown in the figure. The metal hinge 6 is covered on each chip of the motherboard 1 , and the shape of the metal hinge 6 is a sheet structure, and its size is smaller than that of the motherboard 1 . In this embodiment, the metal hinge 6 covers the antenna end of the motherboard 1 . The metal hinge 6 is made of one or more metal conductive materials, such as copper, aluminum and silver. The connecting piece 7 hinges the metal hinge 6 on the main board 1 , so that the metal hinge 6 is firmly on the main board 1 . The conductive foam 9 is l...

Abstract

The invention provides a mobile phone with a metal hinge, which comprises a mainboard, a metal hinge covering a chip of the mainboard, and a connecting part hinging the metal hinge on the mainboard, wherein the metal hinge is provided with a height difference loop metal object. The mobile phone uses the metal hinge to replace all the metal shield covers on the traditional mobile phones, the height difference loop metal object is arranged on the metal hinge, and thus the die sinking cost for developing a large quantity of shield covers can be saved, and the performance of the mobile phone can be improved greatly.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mobile phone with a metal hinge. Background technique [0002] With the rapid development of communication technology, mobile phones have more and more functions, resulting in more chips arranged on the main board of the mobile phone. Usually, in order to reduce the high-frequency noise of the mobile phone or avoid the mutual interference of high-frequency signals, all chips are placed on the top of each chip. Add a metal shield. Such as figure 1 As shown, four metal shields 2, 3, 4, 5 are installed on the main board 1 to shield the chips under it. Yet, increase so many metal shields and just must open the moulds of different sizes according to the size of chip and cover chip, have increased the cost of mobile phone like this; And, so many metal shields also can't make mobile phone Get a better performance, such as mobile phone antenna radiation efficiency is still poor.
