Panel is depressed, and when F is negative value, processor judges that finger leaves panel, and the span of setting time is t, setup parameter A
=F/ t, the slope of a curve of power is indicated with A, to reflect the trend of pressing force, when A value is greater than the threshold value B of setting, is sentenced
Break as panel just depressed, when F is greater than a setting value C, triggering vibration device vibrates for the first time, when A value is less than
When threshold value D, judge that finger will leave, second of the vibration of triggering vibration device.
Further, by adjusting threshold value B and threshold value D, the response speed of pressing and release and the noise immunity of judgement are realized
Energy.
Further, two or more by die pressing type to detect by regulating time and the Rule of judgment of power.
Further, vibrator uses linear vibrator, and the linear vibrator includes the vibration of BHS2616 model
Device.
Further, the vibration device is fixed on a fixing piece, and the fixing piece is bonded on panel.
Compared with the prior art, effect is positive and apparent to the present invention.The present invention utilizes force snesor detection panel
The finger pressing force being subject to judges that panel is in using the variation tendency of processor detection finger pressing force and presses or discharge shape
State, and vibration is generated by vibration device, to simulate the feeling close to physical button.
