Hi

The speaker on the Nordic Thingy:52 is a 15x11mm Rectangle mini speaker (Part No.: BMS1511F-11C-08H03P LF) from BeStar Technologies. Here is the link to the product page, and attached you can find the datasheet.

I think you should be able to play higher quality sounds, but not stream higher quality than 8-bit 8Hz. We have a python script for converting .wav files into output for .c/.h here. Please note that you need a mono .wav file with 16kHz sample. https://github.com/NordicPlayground/nRF52-teensy-sgtl5000-audio/blob/master/Convert%20Audio%20Sample/How%20To.txt
