1. An audio information transmission system, for transmitting audio information among a two-wheeled vehicle, a mobile terminal and a helmet, wherein the system comprises a media control apparatus and an audio switching apparatus both provided in the two-wheeled vehicle, the audio switching apparatus being connected to the media control apparatus, wherein
the audio switching apparatus establishes a data connection to each of the mobile terminal and the helmet, to receive first audio information transmitted by the mobile terminal and forward the first audio information to the media control apparatus;
the media control apparatus is configured to receive the first audio information and second audio information generated by the two-wheeled vehicle, and mix the first audio information with the second audio information to generate mixed audio information;
the audio switching apparatus is further configured to transmit the mixed audio information to the helmet; and
the audio switching apparatus further comprises an audio identification module for identifying a type of the first audio information received, wherein
the audio switching apparatus forwards the first audio information to the helmet when the first audio information is a call voice, and forwards the first audio information to the media control apparatus when the first audio information is a non-call voice.
