Abstract
A power control method includes: acquiring an offset between a time sequence signal of a left sound channel power supply and a time sequence signal of a right sound channel power supply; determining a delay time of a time sequence signal of a first sound channel power supply based on the offset and a target offset; and delaying the time sequence signal of the first sound channel power supply by the delay time to meet the target offset.
