Title:
TOUCH KEY, CONTROL METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/129745
Kind Code:
A1
Abstract:
A touch key (20), a control method and an electronic device (600). The touch key (20) comprises a first conductive part (21), a second conductive part (22), and a touch part (23). The second conductive part (22) surrounds the first conductive part (21) to form a capacitor structure. The method comprises: receiving touch input acting on the touch part (23) (301); detecting whether the second conductive part (22) has a capacitance change in a plurality of preset directions or not (302); and if the capacitance change exists in the target direction in the plurality of preset directions, determining a control instruction corresponding to the target direction (303). According to the method, when the touch key (20) receives the touch input, the touch part (23) transmits the pressure to the first conductive part (21), so that the first conductive part (21) moves with respect to the second conductive part (22), and the capacitance is changed.
