We generalize the Ericksen-Leslie theory for the dynamics of nematic liquid crystals by including the director-density coupling energy . It corresponds to the cost in energy due to the interaction of spatially varying mass density and the liquid crystal director . A striking confirmation of the theory is achieved by confronting it with experimental data on acoustical Fréedericksz transition.
