画等效电路时,
一个前题:

声波波长是大大地大于音箱和单元的尺寸.

不仅仅是找到找不到的问题,我想水仙放这图的目的是给大家一些启发,复杂的箱体如何等效.

看了“第二部分密封箱”的,有的写得比《扬声器及其系统》还要详细,便如校正系数B。

不知这个出自哪本书?应该还有“第一部分在无限障板中”的,望水仙老师也能张贴出来,谢。

Useful References on Loudspeaker System Design
 
Of all the technical publications on loudspeaker system

design that are presented here, the first six are

particularly useful since they contain a wealth of

collected information. Also, many of the journal

articles published by the Audio Engineering Society that

are referenced in this bibliography are contained within

the AES publications listed at [1] and [2].Please note

that this list is definitely far from exhaustive, there

have been many more contributions to the field of

loudspeaker design than it is possible to include here.
