The metric of some Lorentzian wormholes in the background of the FRW universe
is obtained. It is shown that for a de Sitter space-time the new solution is
supported by Phantom Energy. The wave equation for a scalar field in such
backgrounds is separable. The form of the potential for the Schr\"{o}dinger
type one dimensional wave equation is found.
