Shielding mechanism:
Utilizing the phenomenon of electromagnetic induction（Under the action of external alternating magnetic field）
—Induced current occurs in the shielded shell
—Produce an electromagnetic field in the opposite direction to the external electromagnetic field
—Offsets the impact of external electromagnetic fields on the circuit inside the shielded body
—Achieved shielding effect
