Speaker protection circuit diagram.:
This is the Speaker protection circuit diagram. It can protect our Speaker form burn. if the amplifier got any problem then this circuit can save our soundbox. Normally when the transistor makes a short circuit the voltage comes out from the speaker output line then this circuit protects that voltage. this circuit should not allow any direct voltage to the speaker. this circuit is so important to protect the speaker.
This is the circuit.
We can see that it has two inputs and two outputs. one for the right speaker and another for the left speaker. to run this circuit need 12 voltage.
This is the diagram
