Abstract

The invention provides a screen sounding control system, a method and a mobile terminal. The screen sounding control system comprises an audio decoding device, a driving control module and a piezoelectric vibration module. The audio decoding device is used for decoding an audio signal and obtaining a decoding signal. The driving control module is connected to a position between the audio decoding device and the piezoelectric vibration module. The piezoelectric vibration module comprises two piezoelectric vibration devices. The decoding signal comprises a mode choice signal. The driving control module is provided with two driving channels, wherein each driving channel is used for driving one piezoelectric vibration device, and the driving control module is used for selectively opening one of the driving channels or simultaneously opening the two driving channels and providing corresponding driving gain according to the mode choice signal. The piezoelectric vibration devices are used for further driving a display screen to sound in a vibrating mode under driving of the corresponding driving channels.

Description

technical field [0001] The present invention relates to screen sound technology, in particular, to a screen sound control system and method and a mobile terminal using the screen sound control system. Background technique [0002] A mobile terminal (such as a mobile phone) related to the present invention, its sound system usually includes components such as a loudspeaker, a receiver, and a vibrator, and the above components are respectively used to realize functions such as multimedia playback, call voice playback, and vibration feedback of the mobile terminal . With the development of smart mobile terminals, especially the wide application of large-screen smart phones, the size of mobile terminals is getting larger and larger. In order to reduce the overall volume of mobile terminals, users hope that mobile terminals will develop in a thinner direction. However, speakers, receivers, and vibrators generally need to occupy a relatively large space, which is inconsistent wit...
