Abstract
(EN)
Provided in the present application is a screen sound-generating device; a vibrator and a hard substance having a certain Young's modulus and area are disposed below a screen; the vibrator uses the hard substance to drive the screen to vibrate in a direction perpendicular to the surface of the screen. Therefore, when the vibrator uses the hard substance to drive the screen to vibrate, the area of vibration of the screen is increased by means of the hard substance to cause, as much as possible, most regions of the screen to vibrate so as to produce a better vibration effect.
(FR)
La présente invention concerne un dispositif de génération de son d'écran ; un vibreur et une substance dure comprenant un certain module de Young et une certaine zone qui sont disposés au-dessous d'un écran ; le vibreur utilise la substance dure pour entraîner l'écran à vibrer dans une direction perpendiculaire à la surface de l'écran. Par conséquent, lorsque le vibreur utilise la substance dure pour entraîner l'écran à vibrer, la zone de vibration de l'écran est augmentée au moyen de la substance dure afin d'amener, autant que possible, la plupart des régions de l'écran à vibrer de manière à produire un meilleur effet de vibration.
