Title:
METHOD FOR ADJUSTING DIAPHRAGM VIBRATION BALANCING POSITION AND SPEAKER
Document Type and Number:
WIPO Patent Application WO/2018/107512
Kind Code:
A1
Abstract:
Provided in embodiments of the present invention is a method for adjusting a diaphragm balancing position, comprising the following steps: acquiring the displacement by which a diaphragm vibration balancing position of a diaphragm of a speaker deviated from an initial position, where the vibration balancing position serves for the diaphragm as the balancing position for vibrating when the diaphragm is working, and the diaphragm vibrates at a preset maximum amplitude when the initial position serves for the diaphragm as the balancing position for vibrating; inputting a direct current bias current to a voice coil of the speaker on the basis of the displacement so as to calibrate the vibration balancing position of the diaphragm to the initial position, where the voice coil is arranged on one side of the diaphragm and vibrates with the diaphragm. Therefore, the output of an increased sound pressure level by the speaker is ensured, and improved sound output effects are achieved.
