Comment on Disconnect wire to close a switch with a simple circuit
jeinzi@discuss.tchncs.de 10 hours agoProps for the detailled answer, but this all sounds completely backwards.
Low-side switching should in general use an N-Channel FET. And with your voltage divider, the gate will be at 6% auf the supply voltage, not 94%, which means the FET will always be conducting. It will also never fully turn on, because that would mean the Gate-Source voltage would drop to near 0, which would turn it off again.
My counter proposal:

I don’t think it’s possible place the full module between 4V and Drain (or collector for NPN), so I shifted my focus to just the speaker without all the ICs.
The good news is that it works with both an NPN or a MOSFET - the bad news is that it totally degrades the quality of the audio to a point where the thing I am trying to play is unintelligible.
