Surface mount for Adafruit Mini Metal Speaker (#1890)

A quick and dirty hack to mount the [Adafruit Mini Metal Speaker (product #1890)](https://www.adafruit.com/product/1890) to a surface.

Simply attach the speaker to the flat side of the mount with a few small dabs of hot glue around the rim, then glue (I used superglue gel) the small prongs to something. I used it to mount the speaker to the inside surface of a robot head.
