Abstract

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.

Claims

1. A wireless communicating electronic device, comprising:

a wireless communicating unit;

a shell receiving the wireless communicating unit therein;

a touch sensing unit comprising;

an antenna connected to the wireless communicating unit and configured for transmitting a wireless signal generated by the wireless communicating unit, the shell having a given portion spatially corresponding to the antenna, the antenna further configured for generating an alternating current (AC) signal in response to a finger touch on the given portion;

a regulating circuit configured for regulating the AC signal; and

an analog-digital (AD) converting module configured for converting the AC signal into a digital signal;

a processing unit configured for executing an instruction in response to the digital signal.

2. The wireless communicating electronic device as claimed in claim 1, wherein the wireless communicating unit is a 3G communicating module.

3. The wireless communicating electronic device as claimed in claim 1, wherein the regulating circuit is configured to regulate the value of the AC signal by filtering out high frequency signals of the AC signal and reserving the remaining.
