1. An intake bypass recirculation structure capable of silencing, comprising:
an intake bypass recirculation structure body, wherein an intake bypass recirculation cavity is provided on the intake bypass recirculation structure body in a circumferential direction, the intake bypass recirculation structure body has an inlet of the intake bypass recirculation structure provided on a side close to an outlet of an intake pipe and an outlet of the intake bypass recirculation structure provided on a side close to an inlet of the intake pipe, and the inlet of the intake bypass recirculation structure and the outlet of the intake bypass recirculation structure are each connected to the intake bypass recirculation cavity; and
a structure-conducted silencing device, disposed inside the intake bypass recirculation cavity and comprising two diaphragms, wherein a gas is filled inside a cavity of the structure-conducted silencing device; and
the diaphragms comprise an upstream diaphragm and a downstream diaphragm that are disposed symmetrically, and the upstream diaphragm is connected to the downstream diaphragm by means of a lightweight rigid plate.
