Description
【Technical field】
The present invention relates to communication apparatus auxiliary tool fields, and in particular to a kind of adjustable point touch screen electronic device protective shell.
【Background technology】
Touch-screen mobile phone is a kind of type of cell phone being applied to touch screen technology on mobile phone screen.It is used in touch-screen mobile phone
In the process, it needs to click screen with finger to achieve the effect that use cell-phone function.In the type of numerous touch-screen mobile phones,
Capacitive touch screen is widely used in touch-screen mobile phone, and principle is to plate long and narrow electrode on four side of touch screen, in electric conductor
Form a low-voltage AC electric field.When user touches screen, due to human body electric field, finger can form a coupling with conductor interlayer
Capacitance is closed, the electric current that four side electrodes are sent out can flow to contact, and electric current power is directly proportional at a distance from finger to electrode, be located at and touch
Touch the controller after screen will calculating current ratio and power, the accurate position for calculating touch point.For finger injuries and
It is lived by bandage or the capacitive touch screens cellie with gloves, screen can not sense the electrostatic of hand；When making
When being touched to screen with other positions of body, cell-phone function can not be often used due to can not be accurately positioned to certain point, is given
User causes to perplex.
【Invention content】
In view of the above problems, it is necessary to a kind of adjustable point touch screen electronic device protective shell is provided, it can be in finger
It is injured and lived by bandage or with gloves in the case of can use capacitive touch screen mobile phone and accurately be pinpointed.
In order to achieve the above objectives, the technical solution adopted in the present invention is：
Part occurs for a kind of adjustable point touch screen electronic device protective shell, including shell and micro- electricity, and part occurs for micro- electricity
It is fixed on the shell including stationary power generation item, flexible touch screen stick, dislocation generation item and fixed point stick, the stationary power generation item,
The flexibility touch screen stick is slidably connected by the dislocation generation item and the stationary power generation item, the dislocation generation stress energy
It is enough to be moved with triboelectricity along the stationary power generation item, the binding energy of the dislocation generation item and the flexible touch screen stick to electronics
Power is all higher than the stationary power generation item, so that the dislocation generation item and the flexible touch screen stick electrification, described flexible tactile
