在仿真箱体时，怎么等效呀

The box component describes the compliance and loss in a cavity
of air in a box with a given volume. For a simple bass-reflex box one
box component is connected to the backside of the diaphragm, a
box load component is also needed to simulate the air load of the
backside of the diaphragm. The properties that can be set are:
V: Box volume, i.e. the volume excluding the volume that
drivers, passive radiators and ports occupy.
fill: Estimated fill of damping material in the box
Qb: Box Q-value due to damping material in the box
Ql: Box Q-value due to leakage from the box.
