Abstract:
The present invention discloses a screen sounding device, including a screen, a frame and an electromagnetic driving module. The electromagnetic driving module includes an electromagnet, a magnetic conduction base and a magnetic conduction covering plate. The strength of the driving force can be controlled by changing the magnitude of the electric current flowing into the coil, which can provide a greater driving force to obtain a better sound effect. In addition, the driving module of the present invention has a simple structure and can be easily installed; the vibration amplitude of the screen is small, and the sounding device can be made thinner and smaller; compared with the traditional speaker and receiver, the structure such as the diaphragm is omitted, and the manufacturing cost is lower.
