Eccentric Rotating Mass vibration motors (ERM) is motor with a off-set weight attached so when drive signal is attached, the off-set weight spins and causes a sinusoidal wave that translate into vibrations.

##### LRA
Linear resonant actuators (LRA, also know as a linear vibrator) works different from a ERM. A LRA has a weight and magnet suspended by springs and a voice coil. When the drive signal is applied, the weight would be vibrate on a single axis (side to side or up and down). Since the weight is attached to a spring, there is a resonance effect at a specific frequency. This frequency is where the LRA will operate the most efficiently. Refer to the motor's datasheet for the recommanded range for this frequency.

#define FB_ERM_LRA 1
