Metal shell and manufacturing method thereof, mobile terminal employing metal shell

Abstract

The present invention provides a metal shell and its manufacturing method, and a mobile terminal using the metal shell, which is used for assembling with the mobile terminal. The metal shell is provided with a plurality of first insulating layers, and the first insulating layers will The metal shell is divided into a plurality of mutually independent metal blocks, and the first insulating layer and the metal blocks are arranged on the surface of the mobile terminal. The metal shell and its manufacturing method proposed by the present invention can not only eliminate the influence on the wireless signal of the mobile terminal, but also reduce the metal content of the mobile terminal shell and reduce the metal content by setting the first insulating layer and the second insulating layer on the metal shell. The coupling effect between the housing and the antenna and the energy consumption of electromagnetic waves. At the same time, the size of the first insulating layer and the second insulating layer is at the micron level, which is difficult to detect with the naked eye, so that it will not affect the appearance of the mobile terminal product.

Description

technical field [0001] The invention relates to the technical field of mobile terminal products, in particular to a metal shell, a manufacturing method thereof, and a mobile terminal using the metal shell. Background technique [0002] With the continuous development of Internet technology, the application functions installed on mobile terminals are more and more extensive, and these functional applications are more or less inextricably linked with wireless signals. [0003] At the same time, due to its high-end appearance quality and strong metallic visual impact, metal is increasingly favored by consumers. Consumers' pursuit of mobile terminal appearance materials has gradually changed from plastic to metal. The absorption is very strong, but wifi, 2G, 3G, 4G, GPS and other wireless signals have relatively short wavelengths and weak diffraction capabilities. If the mobile terminal shell is all metal, electromagnetic waves cannot reach the signal receiving module of the mob...

[0003] At the same time, due to its high-end appearance quality and strong metallic visual impact, metal is increasingly favored by consumers. Consumers' pursuit of mobile terminal appearance materials has gradually changed from plastic to metal. The absorption is very strong, but wifi, 2G, 3G, 4G, GPS and other wireless signals have relatively short wavelengths and weak diffraction capabilities. If the mobile terminal shell is all metal, electromagnetic waves cannot reach the signal receiving module of the mobile terminal. Naturally, the terminal has no way to receive signals normally and affects the use of its functions, thus the "antenna gate" event of mobile terminal products has appeared, which has been criticized by consumers

[0004] In order to avoid the loss of mobile phone signal, the current general practice is to hollow out certain positions of the all-metal casing of the mobile terminal and use plastic to block it. Although this method reduces the loss of signal energy, it affects the overall appearance of the product and is not consumed Accepted by readers, it is jokingly called a "plastic patch" on the high-end metal appearance of mobile terminals
