A Case Study on the Repetition of Dominant Categories: Focusing on the Speaker Industry

Recently, as competition between countries in cuttingedge technology has intensified, the term "technological hegemony" has been coined.Each country continued to attempt to secure a dominant design by guaranteeing technological superiority.Suarez(2015) argued that a dominant category is formed as a precursor before a dominant design emerges.The purpose of this study is to examine the concept of dominant categories and demonstrate the repeatability of dominant categories through a case study of the emergence, formation, and diffusion of categories in the acoustic speaker industry.To this end, first, we analyzed the process by which dominant categories are repeatedly formed in the speaker industry, and looked at the process by which specific categories are selected in the market through the diffusion stage of new categories, forming dominant categories, and converging categories that were not selected. .Second, we looked at the process of emergence, formation, and diffusion of artificial intelligence speaker categories in the speaker market and looked into the prospects for the emergence of dominant categories in the future.
