This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor creates a short circuit, the voltage is discharged from the speaker output line, and this circuit protects against that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker
