摘　　要：音箱制作中,闭箱和倒相箱都是常见的设计。主要讨论了这两种设计方案的取舍问题,以及具体到小型扬声器的设计上,适用于大型普通扬声器的原有判据是否继续有效。介绍了闭箱/倒相箱设计的朋P和Q'判据,分别讨论其适用范围。经过推理,给出了倒相箱设计的合理条件,并指出,该条件在小型扬声器上是很难实现的。The closed - box loudspeaker and the vented - box loudspeaker are two common types of cabinet designs. How to choose between the two kinds of loudspeaker cabinets and whether the current criterion applied on loudspeakers of normal sizes still suffice in miniature loudspeaker design eases are discussed. The definition and applicable range of EBP and QTS criteria are introduced. It is pointed out that a vented - box condition for miniature loudspeakers is hardly obtained.
