VIBRATION DIAPHRAGM CONTROL CIRCUIT, VIBRATION DIAPHRAGM CONTROL METHOD, CHIP AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/242101
Kind Code:
A1
Abstract:
Provided in the present application are a vibration diaphragm control circuit, a vibration diaphragm control method, a chip and an electronic device. The vibration diaphragm control circuit comprises: N input signal transmission circuits, N gain adjustment circuits, a comparator and N gain adjunct circuits. The method comprises: acquiring gains of a plurality of stereo electroacoustic conversion unit branches in a vibration diaphragm control circuit, then superimposing preset gain values, so as to obtain a reduced gain value in each circuit, and taking the minimum value in each circuit on the basis of the reduced gain value; and then respectively superimposing the corresponding preset gain value on the basis of the minimum value. Gains of a plurality of stereo electroacoustic conversion units are linked, and the relative signal amplitude of a plurality of processed sound tracks is relatively constant, and it is thus ensured that the performance of the stereo electroacoustic conversion units that have a high sound amplitude bearing capacity is exerted as much as possible on the premise that the stereo electroacoustic conversion units that have a low sound amplitude bearing capacity can be free from wire breakage or burning-out.
