A driving circuit, configured to drive a speaker load, comprising:
- a charging circuit, controlled according to an input signal, coupled between a voltage source and the speaker load, configured to form a first current from the voltage source to the speaker load;
- and
- a discharging circuit, controlled according to the input signal, coupled between the voltage source and the speaker load, configured to form a second current from the speaker load back to the voltage source;
- wherein the speaker load is a capacitive speaker load;
- wherein the second current is configured to recycle an energy stored within the capacitive speaker load back to the voltage source.
