The low pass filter circuit is selected from the group consisting of a Butterworth-type filter, a Chebyshev-type filter, an inverse Chebyshev-type filter, an elliptic function-type filter, and a Bessel-type filter. The low-pass filter circuit can filter out the audio noise which is more than 12KHz and cannot be heard by human ears. Among them, the butterworth filter has an advantage of flattening the in-band signal, and can reduce new noise caused by the external music signal passing through the signal processor 31. The mixing circuit 32 is configured to superimpose and mix the signals input from the signal processor 31 and the signal generator 11 so that the output signal includes both the second vibration signal from the signal processor 31 and the first vibration signal from the signal generator 11. Thus, the human body can finally feel the vibration frequency of the external music.

When the magnitude of the current is within the safe value range, the latter-stage vibration device 14 receives the signal output from the first power amplifying circuit 12, and the vibration device 14 will vibrate synchronously with the frequency of the input signal.

When the user selects the manual mode on the man-machine interaction unit 5, the main control circuit 6 sets the limit on the highest vibration intensity according to the detected weight information of the user, the user adjusts the parameters such as the vibration frequency, the vibration amplitude, the program running time and the like through the user setting unit 5b, the main control circuit 6 controls the signal generator 11 to output the first vibration signal set by the user according to the input parameters, the second vibration signal is mixed through the mixing circuit, and the voice coil motor is driven to brake up and down after the amplification of the power amplification circuit 12, so that the vibration device 14 is driven to vibrate up and down.
