Abstract
A portable audio control system that controls an audio signal transmitted from an electronic device, including an earphone device and an audio control device. The audio control device includes an audio source receiver, a signal synthesis module, and an audio output unit. The audio receiver, which is connected with the electronic device, is used for receiving the audio signal. The signal synthesis module receives both the audio signal and a voice signal coming from an external audio resource, and then synthesizes those signals. The audio transmitter is used to output the synthesized sound to the earphone device. As users utilize the portable audio control system to connect with the electronic device, both sound from the electronic device and the external voice or song can be listened at the same time.
