[embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
The first embodiment
As shown in Figure 2, it is the screen sound-producing device 100 of the first embodiment of providing of the utility model, this screen sound-producing device 100 comprises a screen, described screen (not label) sound-producing device 100 also comprises the piezoelectric actuator 103 that directly is attached at described screen below, described piezoelectric actuator 103 passes to screen by moment loading with self deformation, thus the screen vibration sounding.Described screen is the double-decker that comprises touch-screen 102 and display screen 101, described display screen 101 is positioned at the below of described touch-screen 102, described piezoelectric actuator 103 is attached at the below of described display screen 101, namely on the one side of described display screen 101 away from described touch-screen 102.What described piezoelectric actuator 103 adopted is the multilayer piezoelectric ceramic sheet.So-called moment loading refers to: when a slice multilayer piezoelectric ceramic sheet expanded, its bottom that will drive screen was divided and is expanded, and the upper part of screen will shrink, and whole like this screen will occur bending and deformation; Otherwise when a slice multilayer piezoelectric ceramic sheet shrank, its bottom that will drive screen was divided and is shunk, and the upper part of screen will expand, and so repeatedly, whole screen forms flexural vibrations, thereby screen can promote air and produce sound.In the middle of the present embodiment, the quantity of described piezoelectric actuator 103 is 2, described 2 piezoelectric actuators 103 respectively near its separately adjacent screen minor face 101a arrange, described 2 piezoelectric actuators 103 be arranged in parallel.So-called screen minor face 101a refers to the minor face 101a of the display screen 101 that piezoelectric actuator attaches, and the long limit of screen that equally hereinafter is about to set forth refers to the long limit of the display screen that piezoelectric actuator attaches.Touch-screen 102 is provided with the part 104 that exceeds display screen 101 and is used for being fixed whole screen sound-producing device 100 by material fixed supports such as foam or silicon rubber to install in realistic model.
