  In present work, the evolution of scalar field and electromagnetic field
under the background of the charged black-bounce spacetimes are investigated,
and we obtain an obvious echoes signal which appropriately reports the
properties of the charged black-bounce spacetimes and disclose the physical
reasons behind such phenomena. Furthermore, by studying the quasinormal
ringdown, we analyze the three states of the charged black-bounce spacetimes in
detail, our results show that the echoes signal only appears when $(\rvert
{Q}\rvert \le m)$ and $(\rvert {l}\rvert > m+ \sqrt{m ^{2}-Q^{2} })$ in this
spacetime, while when the parameters demand $(\rvert {Q}\rvert>m)$, the echoes
signal will be transformed into a quasinormal ringdown of the two-way
traversable wormhole, and the charged black-bounce is a regular black hole with
normal horizons by requiring $(\rvert {Q}\rvert \le m)$ and $(\rvert {l}\rvert
< m- \sqrt{m ^{2}-Q^{2} })$.
