Abstract

Provided are a sound actuator for a screen and an electronic apparatus applying the sound actuator for a screen. The electronic apparatus comprises the sound actuator for a screen, and the sound actuator for a screen comprises a magnetic circuit system and a vibration system driving the screen to vibrate and generate sound. The magnetic circuit system comprises a lower base board and a magnetic steel structure fixed to the lower base board. The magnetic steel structure encloses and forms an accommodating space. The vibration system comprises a voice coil inserted into the accommodating space and an upper cover board fixedly connected to the voice coil. The sound actuator for a screen further comprises a middle frame fastener fixedly installed to the magnetic circuit system, and an elastic member having one end fixedly connected to the magnetic circuit system and another end fixedly connected to the vibration system. The present invention enables integration of the magnetic circuit system and the vibration system into an integrated actuator, thereby improving assembly precision and overall performance.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustics, in particular to a screen sound exciter and electronic equipment. 【Background technique】 [0002] With the popularization of full-screen mobile phones, the original 16:9 screen is gradually replaced by 18:9. Various manufacturers are scrambling to expand the screen-to-body ratio of mobile phones. Some mobile phones have already achieved a screen-to-body ratio of more than 90%. The placement of the receiver is becoming increasingly difficult, especially the position of the traditional receiver, which is gradually hidden or even canceled; at present, the traditional receiver is still dominated by a dynamic receiver, and the problem of opening the receiver position on the screen was not solved until the appearance of the screen sound technology. The principle is to use an actuator to drive the front screen and structure, and use the screen as a vibrating body to generate sound waves through vibr...
