We suggest some possible interpretations for the $D_{SJ}^+(2632)$ observed by SELEX. The $D_{SJ}^+(2632)$ could be the first radial excitation of the $1^-$ ground state $\rm{D_s}^*$(2112), and its unusual decay patten might be hopefully explained by the node structure of the wave functions. In addition, the $D_{SJ}^+(2632)$ could also be a $c\bar sg$ hybrid state or a $(cs)_{3^*}-(\bar s\bar s)_{3}$ (diquark-antidiquark) bound state.
