Abstract
(EN)
Provided is a screen sounding apparatus and an electronic device. The apparatus comprises a screen (11) and an exciter (13) fixed to the screen (11). A set distance is provided between the center of mass of the exciter (13) and the center of mass of the screen (11) in a direction perpendicular to a main surface of the screen. A vibration direction of the exciter (13) is parallel to the main surface of the screen (11). The screen sounding apparatus improves the problem of sound leakage.
(FR)
La présente invention concerne un procédé de sonorisation d'écran et un dispositif électronique. L'appareil comprend un écran (11) et un excitateur (13) fixé à l'écran (11). Une distance définie est prévue entre le centre de masse de l'excitateur (13) et le centre de masse de l'écran (11) dans une direction perpendiculaire à une surface principale de l'écran. Une direction de vibration de l'excitateur (13) est parallèle à la surface principale de l'écran (11). L'appareil de sonorisation d'écran améliore le problème de fuite sonore.
(ZH)
一种屏幕发声装置以及电子设备。该装置包括屏幕(11)和激励器(13),激励器(13)被固定在屏幕(11)上,激励器(13)的质心与屏幕(11)的质心在垂直于屏幕(11)的主表面方向上具有设定的距离,激励器(13)的振动方向平行于屏幕(11)的主表面。该屏幕发声装置能够改善漏音的问题。
