Question How to make small 8 Ohm reproductor sound louder.

[zapitch]

Hello guys,

I tryed to play some sounds using ESP32 and PWM . Sadly, its not really loud and I cannot make it louder, since my amplitude is almost at its max.

Is there a way to make it louder ? Im using small reproductor from Brio train and Brio made it sound way louder than I can. Im using 3.7V battery to power ESP32.

You need an audio amplifier hat. Something like this -- https://www.amazon.com/MakerHawk-Am...pcontext&ref_=fplfs&psc=1&smid=A1NOQTMMT39TJ0

Brio trains are using TRSP5043A microcontroller and 0.25W small reproductor. Its loud enough.
