主题：AES历史上第一次以扬声器为主题的专题会议演讲嘉宾有中国面孔

请在大会的首页看大会的介绍,你所说的应该是AES其他类别的一个分会议，因为在AES的conference 历史上没有查到你所说的会议：

Although the AES Conference series has already reached its 51st event, this will be the first conference to tackle this subject and associated technologies (signal processing, measurement, testing). This is the perfect opportunity to summarize the current status, look backwards at the historical development and also take a look forward at new technology opportunities. As the conference aims to look at the entire field of loudspeaker and headphone technology, the organizers encourage both current research papers and the submission of historical, review and tutorial papers.
