Abstract
A computer keyboard integrated with Internet phone service includes a keyboard controller, a USB hub and an audio controller. The keyboard controller receives an input command from the keyboard. The USB hub relays the signal of the keyboard controller to the computer, and relays the digital signal of the computer to the audio controller, and relays the digital signal of the audio controller to the computer. Moreover, the audio controller receives the digital signal from the USB hub and converts the analog signal to analog signal. The audio controller receives the analog signal from a conversation unit and converts the analog signal to digital signal for sending to the USB hub and then sending to the computer.
