Abstract

The invention provides a sound-generating device, which includes a basin frame, a vibration system and a magnetic circuit system respectively fixed to the basin frame, and the vibration system includes a diaphragm fixed to the pot frame, a voice coil fixed to the diaphragm, and a And connected to the elastic support assembly at the end of the voice coil away from the diaphragm; the magnetic circuit system includes a yoke fixed to the pot frame, a main magnet fixed to the yoke, two auxiliary magnets on opposite sides of the main magnet and a stack The splint provided on the auxiliary magnetic steel; the splint includes the main body part stacked on each auxiliary magnetic steel, the fixed part fixed on the frame and forming a height difference with the main body, and the connecting part connecting the main body and the fixed part, the main body, The fixed part and the connecting part together form a ring structure, and the fixed part is closer to the diaphragm than the main part. Compared with related technologies, the sound emitting device of the invention has high reliability and excellent acoustic performance.

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 for playing sound are widely used in smart mobile devices such as mobile phones. 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. [0003] The vibration system of the sound-generating device in the related art includes a diaphragm fixed on the basin frame for vibrating and sounding, a voice coil attached to the diaphragm, and a support on the end of the voice coil away from the diaphragm to strengthen the The lateral stability elastic...
