The invention discloses a voice coil motor. The voice coil motor comprises a base, a coil carrier, a coil, a magnet and a lens carrier, wherein the coil carrier is arranged on the base; the coil carrier is provided with a hollow ball groove at the inner side; the coil is arranged outside the coil carrier; the magnet is arranged outside the coil; the lens carrier is arranged inside the coil carrier; and the lens carrier is provided with a curved surface part which is arranged at the outer side and corresponds to the ball groove. The voice coil motor is simple in structure, and is capable of realizing dip angle adjustment under the condition of not increasing the whole thickness of the voice coil motor so as to further improve the imaging effect of the cameras, especially the dual cameras; the dip angle adjustment is completed in the voice coil motor, and after the dip angle adjustment, dip angle change is not caused by external force; and the voice coil motor is convenient to assemble, easy to operate and strong in reliability and stability, and is capable of solving the problem that the process of firstly adjusting dip angle and then dispensing to fix in the prior art needs strict process requirements and has a certain dip angle after the adjustment.
