Abstract
The present invention discloses a speaker unit, a speaker system, and a method for adjusting a vibration displacement of a vibration diaphragm. The method for adjusting a vibration displacement of a vibration diaphragm comprises: obtaining a vibration displacement of a vibration diaphragm; when the vibration displacement is less than a designed amplitude of the vibration diaphragm, increasing an output voltage output by a smart PA to a vibration voice coil till the vibration displacement is equal to the designed amplitude; when the vibration displacement is equal to the designed amplitude, maintaining the output voltage output by the smart PA to the vibration voice coil to enable the vibration displacement to be equal to the designed amplitude; and when the vibration displacement is greater than the designed amplitude, reducing the output voltage output by the smart PA to the vibration voice coil.
