Abstract

The invention provides a sound-generating device, comprising a basin frame, a vibration system fixed to the basin frame, a magnetic circuit system for driving the vibration system to vibrate and sound, and a magnetic frame for fixing the magnetic circuit system to the basin frame A sealing cover; the magnetic circuit system includes a magnetic yoke and a magnetic steel fixed to the yoke, and the magnetic frame sealing cover includes a bottom wall and an annular side wall bent and extended from the periphery of the bottom wall, The yoke is fixed on the bottom wall, and the side wall is fixed on the frame. Compared with the related art, the acoustic performance of the sound emitting device of the invention is better.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a sound generating device used in portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. Sound-generating devices such as loudspeakers and receivers for playing sound are widely used in smart mobile devices such as mobile phones. [0003] The vibration system and magnetic circuit system used in the sound-generating device are directly related to the sound quality of the sound-generating device. In order to enhance the stability of the vibration system, the vibration system of the sound-generating device in the related art includes a first diaphragm fixed to the frame, a voice coil that drives the first diaphragm to vibrate and produce sound, and a lateral...
