Background technology
In recent years, capacitance type touch key and capacitive touch screen, due to its is simple in construction, thickness of thin, it is in light weight, can
More and more extensive application is obtained by the features such as property is high, fault rate is low.With the continuous development of this technology, particularly correlation
The continuous decline of component cost, capacitance type touch key will gradually substitute traditional mechanical key and resistance-type button.
The general principle of capacitance type touch key is to pass through human body（Finger）Touch so that the position being accordingly touched
Direct-to-ground capacitance value change, chip will detect this capacitance change, and by corresponding analog and digital signal
Reason, judges whether button is touched（Press）, correspond to the different press key message of generation and be sent to main frame.At present, existing electric capacity
Formula keyboard is the keyboard based on capacitance-type switch, and principle is that the change of capacitance is produced by the interelectrode distance of key change,
Being temporarily forming concussion pulse allows the condition that passes through, and this switch is contactless contactless, and wear rate is minimum or even can be with
Ignore, be also not in contact with bad hidden danger, but not only technics comparing is complicated and production cost is high for this structure, and bring
How to make user perceive touch or press by the problem of, it is therefore, more in the prior art to realize touch-control feedback using vibration function, i.e.,
The button is turned on when user touches, producing vibrating effect by host software motor notifies user, this mode power consumption
And effect is unnatural, or using the elastic characteristic of keycap itself voluntarily returns and release, be much not enough to produce it is apparent that power is released in its time
The raw force feedback effect for being available for human body to understand perception, and need certain stroke space and cause the overall thickness of keyboard inclined
