Online audio broadcasting is a new way for people to communicate，which people can use to listen to the live broadcast from other places through the Internet. This article takes the new media social responsibility as the theoretical perspective and examines the social responsibility of two online audio live broadcast platforms of Litchi FM and Himalayan FM through content analysis. The study found that the two live online live broadcast platforms are music and entertainment，and they are too single，and there are media violence problems. From the perspective of the implementation of new media social responsibility，the two platforms are in information production，social supervision，and entertainment. The scores on the four indicators of coordination and coordination are relatively close and low，and the implementation of social media responsibility of new media is not satisfactory. This article proposes a new idea for the study of media social responsibility for online audio live broadcast.
