A microscopic semiclassical Vlasov equation approach is used to investigate the dipole giant resonances of spherical cluster Na14. The main strength distributions of collective response function are located around 2eV region, with a fair agreement with the experiment ones. The results are quite independent of the choice of parameters of the mean field.
