Embodiment 1

[0038] An embodiment of the present invention provides a metal casing, figure 2 A top view of a metal casing provided for Embodiment 1 of the present invention. Such as figure 2 As shown, four slit areas B1, B2, B3, B4 are set on the metal shell, and each slit area B1, B2, B3, B4 contains n slits, wherein n is an integer not less than 1, and each slit The width is less than or equal to the set value so that each gap is invisible to the naked eye. figure 2 A partial enlarged view of the slit area B1 is also given, and the slit area B1 includes 10 slits in an exemplary manner, a-j in sequence. Wherein the width of the gap a-j is less than or equal to the set value, so that each gap is invisible to the naked eye, the width of the gap a-j can be equal or unequal to each other, the specific setting parameters can be set according to the application scene, this embodiment is here There is no limitation, as long as the width of each slit is less than or equal to the set value, ...

Embodiment 2

[0044] The metal casing provided by the embodiments of the present invention can be applied to various mobile terminal devices, such as mobile phones, tablet computers and the like. image 3 It is a schematic structural diagram of a metal casing provided by Embodiment 2 of the present invention. Such as image 3 As shown, the metal casing includes a frame 31 , a middle frame 32 and a rear cover (not shown). A gap area E1 is provided on the metal casing, and the gap area E1 is located on the frame 31 and the middle frame 32 . image 3 A partial enlarged view of the slit area E1 is also given, the slit area E1 contains n slits, n is equal to 4, followed by a'-d', E1 contains 4 slits, and the width of each slit is less than or equal to the set value so that each gap is invisible to the naked eye.

[0045] It should be noted that, similar to Embodiment 1, image 3Schematically shows one gap area, and four gaps a'-d' in the gap area, but this is only a specific structure of the...

Embodiment 3

[0051] The embodiment of the present invention also provides a method for manufacturing a metal shell, Figure 6 It is a schematic flowchart of a method for manufacturing a metal shell provided by Embodiment 3 of the present invention. Such as Figure 6 As shown, the method includes:

[0052] Operation 110, processing the metal material into a predetermined shape to obtain a first shell;

[0053] Wherein, the processing technology of the first shell may be stamping the metal material using a numerical control machine tool or a preset stamping die to obtain the first shell. The shape of the first housing can be specifically set according to actual needs. For example, the obtained first casing includes a frame, a middle frame and a back cover, and may also refer to including a middle frame and a back cover, wherein the middle frame and the back cover may be integrally or separately.

[0054] Operation 120, processing at least one gap area on the set position of the first cas...

Abstract

The invention discloses a metal shell, a mobile terminal and a manufacturing method. At least one slot area is arranged on the metal shell; each slot area comprises n slots which are sequentially arranged, wherein the width of each slot is smaller than or equal to a set value, so that each slot cannot be seem by naked eyes, and n is an integer which is not smaller than 1. The manufacturing method of the metal shell comprises the following steps of machining a metal material into set shape to obtain a first shell; forming at least one slot area on a set position of the first shell to obtain a second shell, wherein each slot area comprises n slots which are sequentially arranged, the width of each slot is smaller than or equal to the set value, so that each slot cannot be seem by the naked eyes, and n is an integer which is not smaller than 1. The mobile terminal comprises the metal shell. The antenna slot broken width of the metal shell of the mobile terminal is reduced, and the technical effect of enhancing integrated appearance aesthetic perception of a product is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication terminals, and in particular to a metal case, a mobile terminal and a manufacturing method. Background technique [0002] The antenna is an essential part of the mobile terminal, and it is an important wireless device for transmitting and receiving electromagnetic waves when the mobile terminal communicates with the base station. When the mobile terminal transmits a signal, the antenna is responsible for converting the electrical signal into an electromagnetic wave and radiating it; at the same time, it can convert the received electromagnetic wave into an electrical signal in a timely manner and transmit it to the circuit board inside the mobile terminal. [0003] At present, some mobile terminals (such as mobile phones) use all-metal shells. Except for the front screen, the sides and back of the whole machine are made of metal, which makes the whole machine...
