The invention discloses a method for interaction control of an intelligent mobile phone and a sex appliance via bluetooth and a system thereof. The system comprises a motor, a motor drive circuit, a bluetooth transmission and system control circuit, an intelligent mobile phone application program and a man-machine interaction control mode. The principle is that multiple types of man-machine interaction input related to a sensor are acquired via the intelligent mobile phone application program and converted into signal control instructions; then the signal control instructions are transmitted to the bluetooth transmission and system control circuit via bluetooth software so that a pulse width modulation (PWM) signal is outputted; and real-time speed adjustment and direction control are performed on the motor via the motor drive circuit so that vibration frequency, intensity and direction of the sex appliance are adjusted. The effects of the method and the system are that the control mode and the use scene of the sex appliance can be greatly enriched via combination of man-machine interaction control, signal processing and algorithm processing and the bluetooth connection characteristic of the intelligent mobile phone so that use interestingness, interaction and extensibility of the sex appliance can be increased.
