移动互联网的发展给人们的阅读习惯带来了碎片化、沉浸式的转变，有声阅读产业崛起正是迎合了这一变化。而随着可携带智能终端的逐渐普及，以手机端APP为载体的有声阅读软件占领了大量市场。本文以有声阅读平台的头部软件“喜马拉雅FM”为例，在媒介可供性理论的框架下通过参与式观察法分析其针对大学生用户的可供性特征及局限，在此基础上从喜马拉雅平台选取15名典型的大学生用户进行半结构式访谈，根据访谈得出大学生用户对喜马拉雅FM可供性的具体需求，从而针对平台当前存在的问题一一提出相应的可供性优化路径。力求为平台乃至有声出版行业在大学生细分市场的发展提供一定的策略和方向。

With the development of mobile internet, people's reading habits have shifted towards fragmentation and immersion. The rise of the audio reading industry is precisely in line with this change. With the gradual popularization of portable smart terminals, audio reading apps have occupied a large market share. This article takes the leading audio reading platform "Himalaya" as an example and analyzes its affordance characteristics and limitations within the framework of media affordance theory. Based on the theoretical analysis, participant observation is then used to conduct semi-structured interviews with 15 typical college student users from the Himalaya platform. According to the interviews, specific demands of college students towards the affordance of Himalaya are identified. Consequently, corresponding optimization paths for affordance are proposed for the current problems of the platform, aiming to provide certain strategies and directions for the development of the platform and even the audio publishing industry in the college student niche market.
