Abstract
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.
