1. A haptic synchronized vibration device, comprising:

  • a mounting platform;

    a plurality of vibration actuators connected to the mounting platform, each of the plurality of actuators being configured to output a force onto the mounting platform, in which the force output of each of the plurality of vibration actuators are superimposed onto the mounting platform as a combined force vector, each vibration actuator in the plurality of vibration actuators requiring multiple vibration cycles to go from a rest state to a peak magnitude of vibration; and

    a controller operatively coupled to the plurality of vibration actuators, the controller being configured to control the force output of each vibration actuator and to synchronize the plurality of vibration actuators to produce one or more haptic effects, wherein the controller is operative to control each actuator in order for the combined force vector to sum to zero as a net zero force and a combined torque of the plurality of actuators to sum to zero;

    wherein the controller is further configured to turn haptic effects on and off in the haptic synchronized vibration device, in which the plurality of vibration actuators are put into a first mode where the plurality of vibration actuators are brought up to a given speed and controlled in a manner that their combined force vectors and the combined torque output no haptic vibration effect onto the mounting platform, and in which the plurality of vibration actuators are put into a second mode where a vibration phase of each actuator of the plurality is modified to output a haptic vibration effect without a transition from the rest state up to the given speed.
