Example implementations relate to print substance container vibration. A vibrator for a print system may comprise a motor, and a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container. The vibration may be caused in response to the rotation of an eccentrically loaded weight about a central axis of the vibrator.

A vibratory drum includes a tubular drum having a longitudinal axis, and first and second vibratory generators disposed laterally relative to the longitudinal axis and opposite each other across the tubular drum. The drum also includes a frame to which the first and second vibratory generators are attached; and a plurality of resilient elements attached at a first end to the tubular drum and at a second end to the frame, whereby the vibratory motion of the generators is transferred to the tubular drum to impart a circular motion to material disposed in the tubular drum.

The disclosure relates to integrated modules for Synchronized Array of Vibration Actuators (FIG. 125A). The modules provide physical interface, power and communication interfaces. Each module may include vibration actuators (FIG. 123A) which can be precisely attached and aligned to the module housing, a microcontroller or other microprocessor, and one or more sensors for closed loop control of actuators (FIG. 126G). Interleaved pairs of ERMs having a center of mass in the same plane eliminate parasitic torque. A single module can produce a vibration force that rotates at a specific frequency and magnitude, which on its own could cancel out some types of periodic vibrations (FIG. 125B). Two modules paired together and counter-rotating with respect to each other can produce a directional vibration at a specific frequency and magnitude, which could prove even more useful for canceling out a vibration. Such modules are also employed to produce beating patterns (FIGS. 131-133). Both amplitude and frequency of the beating force are variable.

A method of generating haptic effects on a haptic-enabled device having a control unit and a haptic output device is provided. The method comprises receiving a haptic track that describes a time-varying magnitude envelope for driving the haptic output device to generate a haptic effect. The method further comprises generating a periodic drive signal with a time-varying frequency that is based on magnitude values of the time-varying magnitude envelope described in the haptic track. The method further comprises outputting the periodic drive signal to the haptic output device, to cause the haptic output device to generate the haptic effect based on the periodic drive signal.
