Application of dynamic external fixator in treating distal radial fractures with osteoporosis General specification for electrodynamic loudspeaker of director type 动态外固定架治疗骨质疏松性桡骨远端骨折疗效分析GB/T9397-1996直接辐射式电动锥形扬声器通用规范
Design of Limiting Power Handling Capacity About Dynamic Cone Loudspeaker 限制电动式锥盆扬声器承受功率的设计
Matching of dynamic feedback can expand the low frequency range and realize super& damping and low distortion. In which the acoustic feedback system has simple construction, and can make the loudspeaker super-miniaturized with excellent performance. 动态反馈配接可以展宽低频范围,实现超阻尼和低失真,其中声学反馈系统结构简单,宜于使扬声器系统超小型化,且性能良好。
