WIRELESS COMMUNICATING ELECTRONIC DEVICE WITH TOUCH-SENSING KEY

A wireless communicating electronic device includes a wireless communication unit, a shell receiving the wireless communicating unit therein, a touch sensing unit, and a processing unit. The touch sensing unit includes an antenna, a regulating circuit, and an analog-digital (AD) converting module. A given portion spatially corresponding to the antenna defined on the shell. The antenna generates an alternating current (AC) signal in response to a finger touch on the given portion. The regulating circuit regulates the AC signal. The AD converting module converts the AC signal into a digital signal. The processing unit executes an instruction in response to the digital signal.
