常用的扬声器系统有封闭式,倒相式二大类,对倒相式系统又可分出管道倒相和无源辐射体倒相二种,三种系统各有其优缺点,因而各占有一定的市场。本文首先对此三种系统的主要特性作一综述和比较,然后介绍如何对这些系统进行优化设计,最后述及作者的一些设计体会。 Commonly used speaker system has closed, inverted two categories, the inverter system can be divided into two kinds of phase inversion and passive radiator phase inversion, the three systems have their own advantages and disadvantages, which each have a certain Market. This paper firstly reviews and compares the main features of these three systems, and then introduces how to optimize these systems. Finally, some author’s design experiences are described.
