at least one through hole that allows the back cavity and the front cavity to acousticallycommunicate with each other. The sound wave emitted from the driver unit to the backcavity passes through the through hole and cancels a low-frequency range sound wave ofa sound wave emitted from the driver unit to the front cavity, so that sound quality in alow-frequency range is improved.
