Yes, you will need a converter as there are no microphones that have a micro-usb connection by default that would work with your device.
This is an inexpensive, but good quality converter for your tablet: https://www.amazon.com/Female-Headset-Ad...
You can connect any wired microphone to this adapter. I would recommend this one as it is of high sound quality and will last you a long time: https://www.amazon.com/PoP-voice-Profess...
