Abstract
A touch device includes a touch panel, a circuit board, a vibrating unit and a pressure detection module. The touch panel includes two press regions. When different press regions of the touch panel are pressed by the user, the vibration feedback values generated by different press regions are different.
Claims13
A touch device, comprising:
- a touch panel comprising at least two press regions;
- and
- a circuit board located under the touch panel and electrically connected with the touch panel, wherein the circuit board comprises:
- a storage unit comprising a firmware, wherein the firmware contains at least two range coordinate values, at least two press trigger threshold values and at least two driving voltage values corresponding to the at least two press regions;
- a vibrator that vibrates the touch panel;
- and
- a pressure detector that detects a magnitude of an external force pressed on the touch panel, wherein when the external force is applied to a selected press region of the at least two press regions, the magnitude of the external force is detected by the pressure detector,
- wherein when a coordinate value of the selected press region is within a range coordinate value of the at least two range coordinate values corresponding to the selected press region and the magnitude of the external force reaches a press trigger threshold value of the at least two press trigger threshold values corresponding to the selected press region, the firmware is executed to drive the vibrator to result in vibration according to a corresponding driving voltage value of the at least two driving voltage values, so that the selected press region has a corresponding feedback vibration value.
