摘要：
A thermal model system for estimating a voice coil temperature of a loudspeaker that has frequency dependent parameters to model thermal behavior of the loudspeaker may include a loudspeaker having a voice coil and a magnet, and a thermal model configured to have multiple frequency dependent thermal circuits including the voice coil and the magnet that determine a voice coil temperature which is used to limit input to the loudspeaker to prevent thermal overload of the loudspeaker.
