电-声喇叭振动模型的建立与频率修正
VIBRATIONAL MODELLING FREQUENCY MODIFYING OF ELECTROPHONIC LOUDSPEAKER
【摘要】 借助于动态分析仪SD375,用瞬态测试的锤击法和统计回归分析法,建立汽车电声喇叭的振动模型,并给出实用的统计关系式,使喇叭的工作频率得到修正。
【Abstract】 The electrophonic loudspeaker’s vibration model is established with the aid of instantanoous measurement and statistical analysis with dynamic analyser SD375. The available slatistical relation is obtained by use of regression analysis to carry out the frequency modification of electrophonic loundspeeaker.
