A model was previously proposed for the interaction energy between an accoustic field and the local nematic director. The consistency of the model was verified through nuclear magnetic relaxation and optical experiments. The model was later extended to the smectic A phase, despite the fact that the smectic essence of the problem was never included in the interaction process. In this work we investigate details of this interaction through the inclusion of chemical features of the smectic phase. We show that the acoustic director interaction can be enhanced if the external acoustic field matches an eigenmode of the smectic system.
