Abstract

The invention provides a screen sounding exciter and electronic equipment applying the screen sounding exciter. The electronic equipment comprises the screen sounding exciter. The screen sounding exciter comprises a magnetic circuit system and a vibration system for driving a screen to vibrate and produce sound. The magnetic circuit system comprises a lower base plate and a magnetic steel structure fixed on the lower base plate. The magnetic steel structure is encircled to form an accommodating space; the vibration system comprises a voice coil inserted into the accommodating space and an upper cover plate fixedly connected with the voice coil. The screen sounding exciter further comprises a middle frame fixing piece fixedly installed with the magnetic circuit system and an elastic piece with one end fixedly connected with the magnetic circuit system and the other end fixedly connected with the vibration system. According to the invention, the magnetic circuit system and the vibrationsystem can be assembled into the integral exciter, so that the assembly precision and the overall performance are improved.

Description

[0001] 【Technical Field】 [0002] The present invention relates to the technical field of acoustics, in particular to a screen sounding exciter and electronic equipment. [0003] 【Background technique】 [0004] With the popularity of mobile phones with full screens, the original 16:9 screens are gradually being replaced by 18:9. Manufacturers are vying to expand the screen ratio of mobile phones. Some mobile phones have already reached more than 90% of the screen ratio, but traditional devices It is becoming more and more difficult to place the receiver, especially the position of the traditional receiver, which is gradually hidden or even cancelled. At present, the traditional receiver is still based on the moving coil receiver. The problem of the opening of the screen receiver position is not solved until the emergence of the screen sound technology. The principle is to use an actuator to drive the front screen and structure. The screen is used as a vibrating body to generate sound...
