目前，音箱按箱体结构，分为密闭式、倒相式、空纸盘式等多种类型。密闭式音 箱的缺点是：由于箱体密闭，箱体内外气压得不到平衡，低音扬声器振幅有限，低频 量感不足，箱体庞大。倒相式音箱的缺点是：虽然倒相输出与低音扬声器输出信号相 反的信号，但乃会干扰低音扬声器输出的信号，容易产生低频共振，瞬态变差，制作 和调校相对复杂。活塞式音箱就是在密闭式音箱上装上活塞，或者说在倒相式音箱的 倒相孔上装上活塞，活塞的运动是随低音扬声器振动而振动，活塞的振动不会发出声 音，会把音箱内的声音信号进行吸收、缓和，使低频灵敏度高，解析力好，有效减少 扬声器振幅，箱内不会产生驻波，有效避免声短路和相互干涉现象。平衡音箱内外气 压。尽量挖掘扬声器潜力。活塞式音箱的发明，解决了困扰音箱技术的一个难题，显 著的优点必将会有巨大的市场。热切欢迎音箱界朋友们，到网上查询，进行实验，有 何建议请多指教。 |
You seem know a lot of how speaker system is operating. Im's sorry to say,
your comment can only explaine the differencies of the sealed box and
vented box.
However, you don't even know the theory of these boxes, how can you
suggest a piston to the box.
Do you know why speaker needs a box. ??????
Do you know the function of the speaker box ?????
Have you ever though of when you put a piston instead of the vent, how
will the speaker sounds like????
I wash my ears to listen you great idea.
