Abstract:
A touch device includes a cover plate, a first piezoelectric element, and a second piezoelectric element. The cover plate has a first surface and a second surface. The first piezoelectric element is disposed on the second surface of the cover plate. The second piezoelectric element is adjacent to the first piezoelectric element. The method for operating the touch device includes outputting a first detection voltage signal to the first piezoelectric element to cause the first piezoelectric element to vibrate, receiving a second detection voltage signal from the second piezoelectric element, and determining that a touch event on the first surface of the cover plate has occurred when an energy level of the second detection voltage signal is lower than a predetermined value. The first detection voltage signal has a specific frequency which can cause the greatest vibration of the first piezoelectric element.

Claim (Index 15):
The method of  claim 14 , wherein performing the frequency scan function to set up the specific frequency comprises:\n outputting a series of first testing voltage signals having different frequencies to the first piezoelectric element; and determining the specific frequency according to energy levels of a series of second testing voltage signals transmitted from the second piezoelectric element.
