2007年1月下旬,应邀到珠江三角洲访问。参观一些音响公司、大学、专业媒体……会见许多新老朋友,畅言音响发展,纵论有感话题,实为人生一大快事。此时在北方正值数九寒天,万木凋零,一到白云机场却是暖风扑面,树草皆绿。1300年前唐朝诗人李德裕到广东,有诗“独登高楼望帝京,鸟飞犹是半年程”。当今飞机往返,“铁鸟不用半日程”。足可对比今日科技进步。这次南方之行,伴随着暖风扑面更感到科技之风扑面而来,许多新材料的应用,新产品的开发、新课题的研究……使人感到振奋、愉快。特别使我感到高兴的是,拿到俞锦元先生签名赠送的新著《扬声器设计与制作》。此书2007年1月第一版,俞先生1月24日签字。精装一册,使人爱不释手。2006年11月在黄山市开会时,曾向俞先生问及此书情况,愿先睹为快,现一书在手,颇有感想。
