Abstract: A vibration diaphragm and a manufacturing method thereof are provided. The vibration diaphragm comprises an annular support member, a first vibration diaphragm layer and a circuit layer. The first vibration diaphragm layer is fixedly connected to a support body of the annular support member. The circuit layer is positioned on a surface of the first vibration diaphragm layer that is adjacent to a vibrating voice coil and is fixedly connected to the first vibration diaphragm layer and the support body. The circuit layer is provided with a circuit area, a capacitance area, and a capacitance solder pad. The capacitance area is a capacitance electrode plate formed on the first vibration diaphragm layer. The capacitance area is communicated with the capacitance solder pad by means of the circuit area. The solder pad corresponds to the support body. The reliability of capacitance data acquisition is improved.

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.
