1）， Rtvc是什么意思？

Rtvc - The thermal resistance of the voice coil. The value is related to Pmax as described above. Adjusting this value will change Pmax and vice versa.

2），Levc是否就是LMS参数里的kxm，音圈感抗？

Levc - This value gives the inductance of the voice coil or motor at 1kHz.

3），Fmd,Flp,Qmd,Qlp各是什么意思？

As with the other models the high frequency shaping parameters Fmd, Qmd, Flp, and Qlp are used to adjust the high frequency response based on known transducer performance. The high frequency shaping parameters are selected on a trial-and- error basis. This operation should be performed last after the other parameters have been correctly entered.

Fmd

This parameter controls the mid-high frequency properties of the transducer diaphram. As frequency increases, the moving mass of the diaphram will decrease, resulting in a rising response. This works in an opposite fashion to somewhat compensate for the voice coil impedance which is generally increasing resulting in a falling response. The value is given in KA units of frequency which relates directly to the size of the diaphram. This value can be adjusted to produce a reasonably good match to the known high frequency acoustic response of the transducer.

Flp

This parameter simulates the high frequency properties of the transducer diaphram. At high frequencies diaphram size and construction results in a falling response. The effect is simulated here by a 2nd order Lowpass filter. The value is given in KA units for the relative corner frequency which relates directly to the size of the diaphram. This value can be adjusted to produce a reasonably good match to the known high frequency acoustic response of the transducer.
