The pulse signal output by the main control module 200 can adjust the driving signal output by the vibration motor driving circuit 410 to the vibration motor 420, and the vibration motor 420 changes the working state according to the driving signal, so as to change the output vibration strength. The vibration intensity of the vibration motor 420 can be set to be a massage mode with different gears, and a user can adjust the working state of the massager to a proper massage mode according to the preference of the user. The second button SW1 is an upshift button, and the third button SW2 is a downshift button. When the user uses the vibration motor, if the user presses the second button SW1, the main control module 200 increases the pulse signal output to the vibration motor driving circuit 410 to increase the vibration intensity of the vibration motor 420; if the third button SW2 is pressed, the main control module 200 decreases the pulse signal output to the vibration motor driving circuit 410 to decrease the vibration intensity of the vibration motor 420. The massager can correspondingly complete different key functions by setting different keys, can better meet the requirements of users, and improves the use experience of the users.
In one embodiment, the EMS generation module 700 includes a wear detection circuit 710 and a waveform output circuit 720. The wearing detection circuit 710 is used for detecting whether the user correctly wears the massager. The waveform output circuit 720 is respectively connected with the wearing detection circuit 710 and the main control module 200, and is used for outputting a biological simulation electric signal. The EMS generating module 700 is applied to a massager circuit, and the operating principle is to simulate human muscle bioelectric signals by outputting the bio-simulation electric signals, thereby inducing human muscle contraction motion and achieving a massage effect. The massager is first determined whether the user wears correctly through the wearing detection circuit 710, and the wearing detection circuit 710 can determine whether the massager is in contact with the human body through various ways, for example, sensing a pressure signal on the wearing surface of the massager through a pressure sensor. After the massager is confirmed to be correctly worn by the user, the massager can output a biological simulation electric signal through the waveform output circuit 720 to simulate the nerve biological electric stimulation in human muscle, so that the contraction movement of deep muscle is promoted, a more effective massage function is realized, and the using requirements of the user in all aspects are met.
