Abstract

The invention discloses a sounding screen and a display device.The sounding screen comprises a screen body and an exciter arranged on one side of the screen body, and a sound wave refraction layer anda sound wave reflection layer are sequentially arranged on the surface of the side, away from the exciter, of the screen body in a stacked mode; the sound wave refraction layer comprises a pluralityof protruding blocks with arc outer surfaces, the protruding blocks are used for refracting sound waves generated by vibration to the sound wave reflection layer in the same direction, and the included angle between the reflection face of the sound wave reflection layer and the screen body is an acute angle. The sound wave refraction layer and the sound wave reflection layer are arranged above thescreen, sound waves generated by screen vibration are refracted to the sound wave reflection layer in the same direction through the sound wave refraction layer, then the sound waves are reflected toa specific position through the sound wave reflection layer, the propagation direction of the sound waves can be changed, and the screen makes a sound at the specific position; therefore, directionalsounding is realized, and the privacy of listening to voice or conversation by a user is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of screen sound generation, and in particular relates to a sound generation screen and a display device. Background technique [0002] Based on the design requirements of a full-screen mobile phone and a non-porous appearance, the existing technology provides a screen sound technology that uses the vibration of the screen to generate sound to replace the traditional technology of turning on the earpiece on the mobile phone to generate sound. Screen sound technology has become a research hotspot for realizing full-screen display because it can omit the occupied space of the earpiece on the display screen. Such as figure 1 As shown, the principle of screen sound is to drive the front display screen 2 and its structure through an exciter 1, and use the display screen as the screen body to generate sound waves 3 by vibration, and then transmit them to the human ear. However, the current screen sound has the pr...
