Hi, I'm new to electric and circuit design, wish I'm posting in right forum.
I have 2 speaker playing same source, :
- they will not sound simultaneously
- able to flip/switch the active speaker
My idea is connect one speaker to NPN (SpeakerA) and another to PNP (SpeakerB),
then put 1 pin of microcontroller to HIGH or LOW to flip/switch the active speaker.
I had tested the circuit in below Thinkercad, although it work but i believe something is incorrect,
because if I remove the resistor from the SpeakerA, when its turn, it will also play to SpeakerB
tinkercad - SwitchChannel
are my circuit correct? or any idea why the SpeakerB sound as well when the resistor is removed.
thanks
