1. A camera module comprising:
a voice coil motor comprising a receiving hole;
a lens assembly; and
a dustproof member comprising:
a base plate, wherein a first through hole is defined by an inner surface of the base plate;
a dustproof plate, wherein a second through hole is defined by an inner surface of the dustproof plate; and
a connecting portion;
wherein the connecting portion has a shape of a hollow barrel and defines a hollow cavity, two opposite ends of the connecting portion are respectively connected to an end of the inner surface of the base plate and an end of the inner surface of the dustproof plate, thereby forming a dust collecting groove between the base plate and the dustproof plate; the lens assembly sequentially extends through the first through hole, the hollow cavity and the second through hole, a part of the lens assembly is located on a side of the dustproof plate facing away from the base plate, the voice coil motor is located on a side of the base plate facing away from the dustproof plate, a part of the lens assembly is received in the receiving hole, a surface of the base plate facing away from the dustproof plate is connected to the voice coil motor, the first through hole corresponds to the receiving hole; the connecting portion surrounds along a central axis to define the hollow cavity, along a direction perpendicular to the central axis, a diameter of the hollow cavity gradually decreases from the base plate to the dustproof plate.
