1. damper什么意思

1. 阻尼器：是由弹簧+阻尼器(damper)所组成. 现在那种前后避震的脚踏车用的就是弹簧所提供的是受压时的缓冲,以及吸收压力后恢复原状的能量反弹. 但是单只有弹簧的话会太过敏感,一颗小小的石头都会造成在那边震荡很久,

2. 挡板：另外挡板(Damper)使用将弹性体(Elastomer)注射模塑成形的材料,使挡板的刚性保持一定水平的形状. 其结果,由于可以增大振动板的振幅,从而使输出功率提高为5W,高于过去的3W. 除此之外,该产品还采用了使开口(Port)内的空气容易流动的形状,

3. 风门：大部份传统的设计方法无法顾及系统全压平衡,需要在设计完成之后于文管加上风门(Damper),藉由调整风门来达到所需风量. 以能源的观点来看这是一种浪费,同时会产生额外的噪音问题. 最佳的风管设计应该是避免使用阀门,
