扬声器的热效应与功率压缩
Thermal Effects and Power Compression of Loudspeakers
【摘要】 总结了扬声器的热效应问题研究的进展,并对已有的热模型和功率压缩理论提出修正。给出了不同电输入条件下的音圈和磁体的温度公式。并介绍了一种便捷的测量方法,该方法可在进行扬声器寿命试验的过程中同时测量阻抗和温度。
【Abstract】 Evolvement of the researches on thermal effect of loudspeakers has been summarized. And the existing thermal model and theory of power compression are amended. The temperature expressions of voice coil and magnet structure under different electric input conditions are given. A convenient method is presented,which can be applied to measure impedance and temperature during the life test of loudspeaker.
