Research On The Spatial Construction Of Sound Media

The change of the form of sound media makes the space where the sound is and how it is shaped also change.Therefore,in addition to the diachronic study,we should also include the dimension of "space".In this paper,the research of media space is divided into the "technical view" represented by the school of media environment,the "critical view" represented by the school of Marxism and the "urban view" represented by the school of Chicago,so as to establish the theoretical basis of this paper.Based on CiteSpace's burst detection function,this paper analyzes the evolution of key words in broadcasting research,and finds that the development process of sound media in China can be divided into "family radio period"(1978-1996),"mobile radio period"(1996-2019)and "smart speaker period"(after 2019)according to its media form.In the 1960s,radio was set in the family space and was regarded as "the most important family medium of the 20 th century".However,as the dominant mass media in this period,radio is closely related to political voice,which leads to the lack of personality and individual voice in the radio existing in the family space.Public content makes radio become a tool to implement discipline in the family space,and shapes the family space into a "space for Discipline".The political voice and the environment in which the radio is used constitute a conflict in space,and the voice as a medium has not been fully developed.In the late 20th century,with the competition of visual media and the popularization of mobile Internet,"car radio" and "network radio" became the two main lines of the development of sound media.Sound surpassed the original use scene and became a companion form of mobile scene.The form of audio program began to generalize and innovate.During this period,the spatial characteristics of the sound media conform to the "mobile space" that Newman Castel said.The sound media became the companion of the audience in the space,and the change of the sound media made the space different.Nowadays,with the "third wave" of artificial intelligence,it provides an opportunity for the sound media to return to daily life.The intelligent speaker also makes the sound fixed in the family space.The new media form indicates a new concept of space,and the spatial characteristics of sound media in the era of intelligence can be summarized as "cyberspace".Intelligent speakers have changed the relationship between people and their space,and made people enter an era of media existence with numbers as the basic unit.From the radio with smart speakers,sound media has developed from a single space to a space-time crisscross media space,from private areas to public places,from real scenes to virtual spaces,sound media is everywhere.
