Mobile terminal

Abstract

The invention provides a mobile terminal, which comprises a shell, a touch screen, a CPU, a drive IC and a volume key ceramic wafer, wherein the touch screen is arranged on the surface of the shell; the CPU is electrically connected to the drive IC and is arranged in the shell; the volume key ceramic wafer is arranged between the touch screen and the shell and is used for transmitting the piezoelectric effect which is generated under the pressure to the drive IC to analyze; and the drive IC transmits the analyzed data to the CPU to carry out volume adjustment. According to the mobile terminal provided by the invention, an entity volume key is cancelled and the appearance structure of a machine body is optimized, so that the die cost of structural members is reduced, the product yield of the structural members is improved while a gap between the structural members is reduced, and thus the difficulties in electrostatic discharge and water resistance are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal. Background technique [0002] see figure 1 , figure 1 It is a simplified structural schematic diagram of a mobile terminal in the prior art. [0003] Such as figure 1 As shown, most mobile phone bodies in the prior art are provided with physical buttons, such as the volume button 11 and the power button 12, the existence of the physical buttons will bring the following problems: [0004] 1. Affect the integrity of the ID. The physical buttons will bulge part of the middle frame of the mobile phone, and the integrity of the structural parts will be damaged, thus affecting the beauty of the ID; [0005] 2. Increase the complexity of the structural parts and the cost of the mold. The opening of the physical buttons on the middle frame will increase the difficulty of the production process of the structural parts, which will affect the production...

AI Technical Summary

Problems solved by technology

[0004] 1. Affect the integrity of the ID. The physical buttons will bulge part of the middle frame of the mobile phone, and the integrity of the structural parts will be damaged, thus affecting the beauty of the ID;

[0005] 2. Increase the complexity of the structural parts and the cost of the mold. The opening of the physical buttons on the middle frame will increase the difficulty of the production process of the structural parts, which will affect the production cost and yield of the structural parts; the key dimensions of the physical buttons themselves need to be controlled. This requires a long run-in period for the production mold, which increases the cost of the mold; if the key dimensions of the physical buttons are not properly controlled, problems such as poor hand feeling of the physical buttons and black screen when starting up will appear during the assembly process of the mobile phone on the production line, which will affect the quality of the mobile phone. production capacity;

[0006] 3. The physical buttons will cause gaps on the body, which is not conducive to ESD and waterproofing. There will be gaps between the physical buttons and the middle frame, which will increase the probability of charge entering the phone and the difficulty of waterproofing
