Abstract
A sound generating panel, a display device with a screen generating sound and a method for manufacturing a sound generating panel are provided. The sound generating panel includes sound generating unit groups, each of which includes sound generating units. Each sound generating unit includes a support layer with openings and two piezoelectric structures resonating through a cavity, improving a sound pressure generated by the sound generating panel. Each sound generating unit group includes sound generating units with different radii, thereby realizing sound generating at different frequencies, and improving a sound effect of the sound generating panel. Each of some sound generating unit groups includes ultrasonic detection units for detecting a distance between a listener and the sound generating panel, so that an effect of automatically regulating and controlling a volume of sound is realized. In the display device, the sound generating panel is on a display side of a display panel, so that sound waves can directly enter human ears. The sound generating panel provided by the present disclosure is capable of automatically regulating and controlling the volume of sound and having a vivid sound effect, and the sound generating panel is integrated to the display panel, improving a level of integration of a screen.
