Abstract

An audio control system installed on an electronic device includes a switch switching between a first mode and a second mode, a switching module, a microphone, a microphone control module, a speaker, a speaker control module, a signal radiating module, and a signal receiving module. When the switch is switched to the first mode, the switching module controls the microphone control module to transmit audio data of microphone to the signal radiating module to radiate the audio data via a wireless network. When the switch is switched to the second mode, the switching module controls the microphone control module to transmit the audio data of microphone to the speaker to make sound via the speaker control module.
