Abstract: A negative-pressure controller controls and adjusts a negative pressure and a rhythm intensity generated by at least one accessory body. The negative-pressure controller includes a control panel, a negative-pressure air hole, and a first output port. The control panel is disposed on one side of the negative-pressure controller, and sets an operation parameter. The negative-pressure air hole is formed on one side of the negative-pressure controller, and provides a suction force from the external to the negative-pressure air hole to adjust the negative pressure. The first output port is formed on one side of the negative-pressure controller, and provides a PWM voltage. The negative-pressure controller adjusts a duty cycle of the PWM voltage based on the operation parameter, and the duty cycle is positively correlated with the rhythm intensity.
