WAV Trigger Speaker Can't play the voice

Hello Everyone :

I use a 3.5 audio jack to connect a bluetooth speaker and play the sound through the WAV trigger. But it doesn’t work if you switch to a speaker and connect it directly. Is there a limit to which type of 8 ohm 1W speaker can be used (internal magnet or external magnet)?

Try a pair of stereo headphones or earbuds and see if those work.

I’ve tested stereo headphones or earbuds and they work, but I’d like to use the mono speaker to play the sound through the WAV Trigger. Below is my wiring diagram, is there anything I missed? Thanks for your help.

Have you enabled the on-board audio amp in your init file? It’s off by default. See the Configurator app.

Thank you very much, I have solved my problem according to the way you said. :wink: :wink:
