Problems solved by technology

However, the low-frequency distortion of the sound produced by the piezoelectric ceramic solution in the prior art is relatively large, and the low-frequency is less, and the sound is easy to leak in a quiet situation
The overall solution is large in size, takes up more space for decorations on smart terminals, and is more expensive

Abstract

The invention provides a sound-producing device of a display screen and a smart terminal. The sound-producing device of the display screen comprises a shell, the display screen and an exciter, whereinthe display screen is formed on one surface of the shell, and the exciter is arranged in the shell and located below the display screen; the exciter drives the display screen to produce sounds through vibration in the perpendicular direction of the display screen. In the sound-producing device, the display screen is pushed to vibrate in the front-and-back direction through the exciter to push airto produce the sounds through vibration; the larger display screen can move by smaller distance to push more air to produce the sounds which are equal to these of a telephone receiver in volume; low-frequency response is basically identical to that of the traditional telephone receiver, and has no obvious distorted peaks, the volume is basically identical to that of the traditional telephone receiver, and the price is lower than that in a scheme of piezoelectric ceramics.

Description

technical field [0001] The invention relates to the field of screen sound generation, in particular to a display screen sound generation device and an intelligent terminal. Background technique [0002] With the continuous development of electronic information technology, intelligent terminals such as smartphones and tablet computers have been widely used and become indispensable necessities in users' lives. [0003] Nowadays, the screens of smart terminals are becoming larger and larger. The larger the screen of the smart terminal, the more comfortable it is for users to use, and it can bring users a better visual experience in terms of games and videos. However, in addition to the screen, the front of the smart terminal also has components such as earpieces, which occupy a relatively large area of ​​the front of the smart terminal, thereby reducing the screen area of ​​the front of the smart terminal. The 18:9 full screen of smart terminals has become a trend, which can p...
