Vibrations localized near the surface have been analyzed using the Jacobian matrix method taking into account discreteness of the lattice. It has been shown that localized surface vibrations in layered crystals have got quasi-one-dimensional character and their properties are described by exact solutions obtained in the framework of the one-dimensional model.
