Vibration producing device with narrative and sleep functions

A system for applying vibration to a body of a user, comprising:

• a plurality of vibration producing devices including at least one motor with an axle and at least one unbalanced rotating mass mounted on the axle, wherein the at least one unbalanced rotating mass is coupled to the axle at a point offset from a center of mass of the axle and the at least one unbalanced rotating mass, producing a vibration in the at least one motor with the unbalanced rotating mass when the mass is rotated, and wherein the plurality of vibration producing devices is configured to deliver the vibration to at least a portion of a body;
• an input signal generated by an external stimulus, wherein the input signal is directed to a user and wherein the input signal comprises an audio or visual external stimulus;
• at least one sensor that monitors a biometric feature of a user and an external stimulus sensor that monitors the input signal;
• and
• a controller that controls the plurality of vibration producing devices using a motor drive waveform based on the input signal, to produce the vibration based on the input signal, such that the system applies the vibration based on the input signal to at least a portion of the body of the user, wherein the controller monitors an output of the at least one sensor and the external stimulus sensor,
• wherein the controller is further programmed to control the plurality of vibration producing devices with a feedback loop that generates the motor drive waveform for the plurality of vibration producing devices, wherein the feedback loop alters the motor drive waveform based on the output of the external stimulus sensor and the output of the at least one sensor;
• such that the controller moves the user to a physiological state based on the input signal and the biological feature monitored by the at least one sensor, using the feedback loop that generates the motor drive waveform.
