Ds mesons are investigated in a semiclassic flux tube model where the spin-orbit interaction is taken into account. Spectrum of D-wave Ds is predicted. The predicted spectrum is much lower than most previous predictions. Analysis of some Ds candidates is made. DsJ(2632)+ may be a 1^\ensuremath- jP=(3)/(2)^\ensuremath- or 1 3D1) orbitally excited Ds meson if it really exists. Ds1(2700)^\ifmmode±\else\textpm\fi is very possibly the first radially excited 1^\ensuremath- (jP=(1)/(2)^\ensuremath- or 2 3S1) Ds meson [the first radial excitation of Ds^\ensuremath⋆\ifmmode±\else\textpm\fi(2112)0]. DsJ^\ensuremath⋆(2860)+ should be a 3^\ensuremath- (jP=(5)/(2)^\ensuremath- or 1 3D3) orbitally excited Ds meson, and DsJ(3040)+ is the first radially excited 1+ (jP=(1)/(2)+) Ds meson. Our conclusions are consistent with the latest BABAR experiment.
