The invention discloses a mobile phone motor with a vibrating heat-radiating function. The mobile phone motor comprises a motor transmission shaft, a vibrating device and a heat radiating device, wherein the vibrating device and the heat radiating device are connected with the motor transmission shaft. After the motor is started, the motor transmission shaft drives the vibrating device and the heat radiating device to rotate. The vibrating device adopts eccentric gears as vibrators. When the motor rotates forward, one vibrator can drive the other vibrator to rotate synchronously at high speed to form eccentric force and generate vibrating. When the motor rotate reversely, the two vibrators abuts against paddles and are separate from each other to recover to a balanced state and stops vibrating, and the fan of the heat radiating device continue to rotate and radiate heat synchronously under the rotation of the motor transmission shaft. A vibrating state and a heat radiating state can operate synchronously or only the heat radiating state operates through the conversion of the positions of the vibrators. Under a non-vibrating state, the fan rotate with the motor synchronously, the heat radiating function is achieved, and the bottleneck that the fan can start heat radiating only when the rotators vibrate is avoided through the separating working mode.
