5. The camera module according to claim 1, wherein the number of the position-limiting portions is at least two, the at least two position-limiting portions are disposed on opposite sides of the lens carrier and configured to generate a first magnetic force when the coil is not energized, the number of the position-limiting mechanisms is at least two, the at least two position-limiting mechanisms are disposed in one-to-one correspondence with the at least two position-limiting portions and configured to generate a second magnetic force cooperating with the first magnetic force when the coil is not energized.
6. The camera module according to claim 5, wherein the first magnetic force and the second magnetic force are attracted or repelled.
7. The camera module of claim 5, wherein the limiting mechanism is an electromagnet.
8. The camera module of claim 1, wherein the limiting mechanism is connected to the base or the housing.
9. An electronic device, characterized in that the electronic device comprises the camera module set of any one of claims 1-8.
10. A method of controlling an electronic device according to claim 9, the method comprising:
detecting whether the coil is energized;
if the coil is not electrified, generating a control command;
the limiting mechanism is matched with the limiting part according to the control instruction, so that the lens carrier and the shell are relatively fixed.
