除了效率外,还有其他因素会影响音箱是否易于驱动。我们先来谈谈音箱。不晓得您有没有注意到,某些音箱箱体上有个洞(有的在正面,有的则在背面),在听到打鼓、爆炸时,这个洞就会喷气儿。最早的音箱是没有开孔的,后来有个天才发现,在音箱上打个洞,会让音箱的低音更多一些。结果现在大部分的音箱都有打洞,这种有洞音箱就叫做“反射式音箱”,而原来没洞的音箱就叫做“密闭式音箱”。后来又是一个天才,在音箱那个洞(这个洞叫做“反射孔”,切记切记,连反射孔都不知道的话,铁定会成为音响店老板眼中待宰的肥羊)后面,拉了一条既长又曲折的管子,据称可以有效增加音箱的低频延伸,这种音箱被称作“低音传输式音箱”,又简称为“传输线式音箱”。因为它后面的传输管曲曲 In addition to efficiency, there are other factors that affect whether the speakers are easy to drive. Let’s talk about the speaker first. I wonder if you have noticed that some speakers have a hole in the box (some are on the front, others are on the back). When you hear drumming and explosion, the hole will jet. The earliest speaker is no hole, and later a genius found that making a hole in the speaker, the speaker will make the bass more. As a result, most of the speakers now have holes. This holey speaker is called a “reflective speaker.” A speaker with no holes is called a “closed speaker.” Later is a genius, that hole in the speaker (the hole is called the “reflection hole”, remember, even the reflection hole do not know, iron will become the audio shop owner in the eyes of fat sheep to be slaughtered) behind, pulling a long Also winding pipe, allegedly can effectively increase the speaker’s low-frequency extension, this speaker is called “bass speaker”, also referred to as “transmission line speaker.” Because it behind the transmission pipe
