and by means of a computer parallel port discrete control signals from a controller are input to a digital isolated output card to output a simulation signal the signal is transmitted by a protection device and a driving device to execution mechanisms of the motor the motor and a light device so as to control changes of rotation halt ratio and rotation speed of motors of various washing machines at the same time a response time of the music signal b lags behind that of the music signal a due to mechanical inertia of the motor and the control device and therefore the signal b is transmitted to the control device and a stereo system after a period of delay time so as to ensure that changes of the water flow and the light are synchronous to and harmonious with the music when the washing machine is started to work after a washing program is selected a control program invokes corresponding music according to motor rotation halt ratios and rotation speeds at different time nodes and transmits the music to the user by using a disposed buzzer or loudspeaker in this embodiment a system sets a corresponding sound feature library according to different rotation halt ratios and rotation speeds of a washing machine and the sound feature library stores sounds corresponding to various different frequencies tones and volumes after a user selects a washing program the washing machine starts to work and according.
