Screen Sounding Device

Abstract

The invention discloses a screen sounding device including a screen, a frame, and an electromagnetic driving module. The electromagnetic driving module includes an electromagnet, a magnet and a spring. Electromagnet includes a magnetic core and a coil wound around the outer periphery of the magnetic core. By changing the magnitude of the electric current flowing into the coil, the strength of the driving force can be controlled, so as to provide a greater driving force and obtain a better sound performance. Moreover, the driving module of the present invention has a simple structure and can be easily installed. Because the amplitude of the screen vibration is small, the sounding device can be made very thin. Compared with traditional speaker and receiver, the structure such as the diaphragm is omitted, and the production cost is lower.
