DRV2624: Powering vibration motors using DRV2624 and signal generator

Tool/software:

Hi, please pardon my ignorance, I am not an electrical engineer by trade. I am prototyping a variety of linear resonance actuator vibration motors, which need to be powered by AC, at about 2 V_rms, current levels between 50 mA and 200 mA, and frequencies between 70 and 240 Hz. I have a function generator that is able to produce my desired frequency and voltage. I am having trouble producing enough current to power the motors. I tested the function generator at 2.00 V_rms and measured a current of 31.9 mA.

How can I amplify the current to around 200 mA while maintaining the voltage and frequency?

Thank you very much!
