The invention provides an audio transmission wire used for a VGA distributor. The audio transmission wire comprises a conductor and a protective cover wrapping the conductor. The conductor consists of the following raw materials of, by weight, 100 parts of copper, 60 parts of aluminum, 15 parts of iron, 5 parts of silver, 2 parts of graphene, 1 part of nano silicon dioxide, 2 parts of micron-size kaolin, 0.9 part of beryllium amide, 0.7 part of nano silicon nitride, 1-3 parts of nano magnesium oxide, 2-6 parts of nano mesoporous molecular sieves, 0.4-0.6 part of nickel, 0.1-0.3 part of strontium and 0.3-0.5 part of gallium. The wire is good in conductive performance, resistant to the high temperature, pulling, mechanical damage, cold and freezing, mainly applied to voice transmission of the VGA distributor and good in voice transmission effect.
