1. A touch pad device for a portable electronic device having a displaying device and a casing, adapted to control displacement of a cursor of the displaying device, and the touch pad device comprising:
- a touch pad to detect a contact to generate a first cursor signal;
a support mounted on the casing;
a suspending device connected to the touch pad and the support to allow the touch pad to receive force from being pushed causing temporary displacement with respect to the support; and
a plurality of sensing elements respectively mounted on the support correspondingly to a perimeter of the touch pad, and the sensing elements detecting the temporary displacement enabling a second cursor signal to be generated;
wherein a distance of a cursor movement in accordance with the second cursor signal is greater than the distance of the cursor movement in accordance with the first cursor signal shown on the displaying device.
