目前,声学和机械学一样,被认为是一种濒于绝境的物理学分支。就是说,在这些物理学分支中不再有希望得到崭新的发现。因此,所有这方面的研究成果和技术进步,只不过是根据电声原理的一种改革、发展或新的组合而已。但是,“终结”绝不意味着“僵死”,本文论述的高级高保真扬声器的换能系统就是一例。 At present, acoustics, like mechanics, is considered a near-destructive branch of physics. In other words, there is no hope of new discoveries in these branches of physics. Therefore, all the research achievements and technological advances in this respect are merely a reform, development or new combination based on electroacoustic principles. However, “the end” by no means means “dead”, this article discusses the high-definition speaker transducer system is an example.
