Sound production device

Abstract

The invention discloses a sound production device. The sound production device comprises a frame, a vibrating system and a magnetic circuit system; the vibrating system comprises a vibrating diaphragm, a voice coil, elastic support assemblies and a support skeleton; the support skeleton comprises an annular skeleton main body and at least two skeleton connecting parts outwards extending from the skeleton main body; the skeleton main body is located between the vibrating diaphragm and the voice coil and at least enables the skeleton connecting parts to be connected in pairs; and each skeleton connecting part is provided with a top wall facing the vibrating diaphragm, a bottom wall facing the elastic support assembly and a side wall connecting the top wall with the bottom wall, wherein the top wall is connected with the bottom face of the vibrating diaphragm, the side wall is connected with the side face of the voice coil, and the bottom wall is connected with the corresponding elastic support assembly, so that the voice coil is elastically hung under the vibrating diaphragm. Compared with the prior art, the sound production device is good in stability and acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, 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. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, sound-generating devices for playing sound are widely used in current smart mobile devices. [0003] The sound-generating device in the related art includes a pot frame, a vibration system respectively fixed to the pot frame, and a magnetic circuit system with a magnetic gap; the vibration system includes a diaphragm fixed to the pot frame, The diaphragm is inserted into the magnetic gap to drive the diaphragm to vibrate and produce sou...
