  • Low Power Adaptive Linear Resonant Actuator Driver Using Accelerometer
    Publication number: 20200328711
    Abstract: An accelerometer and a linear resonant actuator (LRA) are mechanically coupled, such as by being mounted to the same circuit board. The output of the accelerometer is evaluated in order to select a drive frequency for the LRA. For example, the drive frequency may be varied while measuring the magnitude of acceleration induced by the LRA. The output of the accelerometer may further be used to perform a fitness tracking function, such as counting steps or detecting an activity level.
