Considering the interaction between the environmental field and the dCS pseudoscalar, we find that the black hole barrier and the external oscillating shell collectively form an effective resonant cavity, which triggers Mathieu instability in the dCS scalar sector. Numerical results show that the optimal driving frequency is set by the length of the resonant cavity.
