| 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. |
