| contents | In present work, the evolution of scalar field and electromagnetic field under the background of the regularized dilatonic black bounces spacetimes are investigated, we obtain an obvious echoes signal which appropriately reports the properties of regularized dilatonic black bounces spacetimes and disclose the physical reasons behind such phenomena. By studying the quasinormal ringdown of the three states of regularized dilatonic black bounces spacetimes, it shows that the echoes signal only appears when $b>2k$. |
