@teto @maxmustermann @Kagekokoro the Wiimote had some cool little things with that speaker. The best one was in silent hill shattered memories, the phone call audio would come out of it. That was awesome.
The dualshock 4 has a speaker on it the does the same thing as the Wiimote. Found out a couple weeks ago actually that you can set it as your audio output in windows lol.
The steam controller, I'm pretty sure, makes all of its various sounds with rumble.
