So I am working on a bioacoustics project part of which is to reproduce certain beetle chirps. The chirps are distributed through 20 to 60 kHz, so I was planning to use Arduino board (I have at my disposal Uno, M0, M0 Pro boards), put the wav files to SD card and play them using tone() function. I found these speakers online, but now I am having hard time trying to understand how do I connect the Arduino pins to the speakers.
I've looked through other threads (some more or less similar to mine) and, as I understand, I need a resistor based on the impedance of the speakers (which is not mentioned in the speaker data sheet) with DAC or, possibly, an amplifier (this is the part I am getting totally lost at).
If anyone could help me with a fool-proof explanation on what do I need to connect the board and speakers (and maybe how), I would really appreciate it.
