Abstract

The invention provides a differential driving structure, a screen and electronic equipment. The differential driving structure comprises a central assembly; at least four groups of peripheral components which are uniformly arranged around the central component, wherein the distances between the peripheral components and the central component are the same; the actuating directions of all the peripheral components are the same, and the actuating directions of the central component and the peripheral components are opposite. According to the invention, through a differential driving mode, the driving directions of the same sound production area are opposite at any time through the two groups of actuating assemblies with opposite driving directions, so that the vibration amplitude of the sound production area is improved, the sound production efficiency is improved, and a high-quality screen sound production effect is realized.

Description

technical field [0001] The present disclosure relates to the field of screen sound generation, and in particular to a differential drive structure, screen and electronic equipment. Background technique [0002] Directly emitting sound through the display screen can realize sound and picture synchronization, effectively use space and save resources, and combine with a large-size screen to increase the sound output power and achieve different sound field effects. Traditional loudspeakers use a flexible membrane combined with an energized coil moving in a magnetic field to drive the flexible membrane to vibrate to produce sound. However, in the existing screen sound technology, when the coil or magnet drives the screen to vibrate, since the screen material is usually glass or polyimide (PI, Polyimide), it does not have excellent vibration performance, resulting in poor sound effect. The sound efficiency is not high, which affects the user experience. Contents of the inventio...
