The invention discloses an audio system having mobile phone and intercom call functions. The audio system comprises a public network audio system, a private network audio system and a diverter switch. The public network audio system is used to process mobile phone call audios. The public network audio system comprises a public network audio processing circuit, a public network radio-frequency circuit and a public network antenna which are serially connected successively. The private network audio system is used to process intercom call audios. The private network audio system comprises an inverting adder, a private network audio processing circuit, a private network radio-frequency circuit and a private network antenna which are serially connected successively. The inverting adder is connected with the public network audio processing circuit. The audio system of the invention has the following advantages that the random switching between mobile phone and intercom call functions can be realized; the number of audio playing devices can be reduced, and the audio system is suitable for a variety of different types of audio playing devices; the recording function is further provided, the public network and private network call voice recoding can be realized through a public network audio processing chip; and the inverting adder is added, so that the circuit structure is greatly simplified.
