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.

Abstract: The present invention discloses a speaker system with a moving voice coil. A conductive material layer is disposed on a front cover of the speaker system and constitutes a fixed electrode plate. A vibrating component comprises a flexible circuit board secured to one side of a vibrating diaphragm. A metal layer is disposed in the middle of the flexible circuit board and constitutes a movable electrode plate. The fixed electrode plate is electrically connected to an external circuit by means of an external terminal disposed on a front cover solder pad. The flexible circuit board extends to the outside of the speaker system and is provided with a solder pad electrically connected to the external circuit. A capacitance monitoring chip is disposed in the speaker system and electrically connected to a capacitor.

Abstract: The present invention discloses a speaker module and a sound production device. The module comprises a module shell and a speaker unit mounted in the module shell. The module shell comprises a shell main body and two fixed pole plates connected fixedly on the shell main body. The two fixed pole plates are insulated from each other, and each of the two fixed pole plates has a connecting portion exposed to the outside of the shell main body. A vibration system of the speaker unit is provided with a movable pole plate, and each of the two fixed pole plates together with the movable pole plate form a variable capacitor. The speaker module is configured to output an electrical signal representing a vibration displacement of the vibration system by the connecting portions of the two fixed pole plates.

Abstract: A speaker sounding hole device includes a speaker single-unit front cover and a module housing. The speaker single-unit front cover is rectangular, the long edges and/or short edges of the speaker single-unit front cover are provided with open grooves, and the speaker single-unit front cover and the module housing are correspondingly assembled by means of the open grooves. The speaker single-unit front cover provided with the open grooves and the module housing form a front cavity of the speaker sounding hole device. Spaces formed by the open grooves are connected with the front cavity of the speaker sounding hole device to form a sounding channel of the speaker sounding hole device. The device can solve the problems of high cost, long tuning time of the product performance, poor sounding effects and low product efficiency.
