Embodiment 1

[0023] This embodiment provides a button of a mobile terminal, such as figure 1 As shown, the button includes a deformation part 1, an inductor 2 and a detection device 3, wherein:

[0024] The deformation part 1 has a conductive function, and it can be pressed and arranged on the casing 4 of the mobile terminal. Specifically, the deformation part 1 in this embodiment is a metal sheet, which is arranged on the side of the casing 4 close to the inductor 2. Specifically, The housing 4 is provided with a frame 41 on a side close to the inductor 2 , and the deformation part 1 is arranged on a side of the frame 41 close to the inductor 2 .

[0025] The above-mentioned frame 41 may be a non-metal frame, or a metal frame, and is preferably a non-metal frame in this embodiment.

[0026] The above-mentioned deforming part 1 is provided as at least one, which is provided according to different functional requirements, that is, each deforming part 1 can correspond to a functional requir...

Embodiment 2

[0035] The difference between the present embodiment and the first embodiment is that the deformation part 1 of the present embodiment is a metal frame, and the side of the shell 4 of the mobile terminal adjacent to the inductor 2 is provided with a metal frame 41, and the frame 41 is the deformation part 1 of the button. In this embodiment, the frame 41 and the deformation part 1 are integrated, which can reduce the processing cost of the mobile terminal.

[0036] The rest of the structures are the same as those in Embodiment 1, and will not be repeated here.

[0037] This embodiment also provides a mobile terminal, which includes the button described in this embodiment.

Abstract

The invention belongs to the related field of keys, and discloses a key for a mobile terminal and the mobile terminal. The key comprises a conductive deformation part, an inductor that is arranged to be opposite to the deformation part and generates mutual inductance, and a detection device used for detecting the current / magnetic field of the inductor, wherein the deformation part is located on a housing of the mobile terminal, and the inductor and the detection device are located in the housing and are connected to a processor in the mobile terminal. According to the invention, by means of the mutual inductance between the deformation part and the inductor, when the deformation part is pressed, the eddy current at the deformation part changes, the current or the magnetic field of the inductor correspondingly changes, the detection device detects the current or the magnetic field of the inductor and sends a corresponding key value to the processor of the mobile terminal, and the processor controls the mobile terminal to generate a corresponding operation. The problem that an existing mechanical key is frequently pressed, resulting in that a pressing key and an elastic key piece are damaged by attrition, is avoided. Meanwhile, dust and vapor are prevented from entering the mobile terminal to cause a fault of the processor.

Description

technical field [0001] The present invention relates to key-related fields, in particular to a key of a mobile terminal and the mobile terminal. Background technique [0002] There are more or less mechanical buttons on the current electronic products. Taking mobile phones as an example, the switch buttons, unlock buttons, volume adjustment buttons, etc. are all mechanical buttons. And the key shrapnel corresponding to the pressing key is formed inside the mobile phone. By pressing the pressing key, the key shrapnel is pressed and contacts the PCB / FPC board to generate a key signal to realize the function of the mechanical key. [0003] The existing mechanical key, with frequent pressing and use, will cause the pressing key and the internal key shrapnel to be worn and cause the pressing key and the key shrapnel to be damaged. Moreover, there is a gap between the mechanical button and the mounting hole on the frame of the electronic product. Dust or water vapor will enter th...
