Problems solved by technology

Although the above structure can prevent glue overflow to a certain extent, since the overflow groove is set on the front cover above the pot frame, due to the effect of gravity, part of the glue will flow over the overflow groove to the reflex ring. Thus greatly affecting the acoustic performance of the speaker module

Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a shell, a magnetic circuit system and a vibration system, the shell is provided with a containing cavity, the magnetic circuit system is arranged in the containing cavity, the vibration system comprises a vibrating diaphragm arranged opposite to the magnetic circuit system, the vibrating diaphragm comprises a central part, a folding ring part arranged around the central part and a fixing part connected to the outer side of the folding ring part, the fixing part is connected with the shell, a glue containing groove is formed in the side, facing the shell, of the fixing part, and the side, back to the shell, of the fixing part is arranged in a plane mode. The sound production device aims to solve the problem of glue overflow between the vibrating diaphragm and the shell and prevent the glue from overflowing to extrude the vibrating diaphragm, so that polarization caused by glue overflow is effectively inhibited, and the reliability of a product is improved.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic conversion, in particular to a sound generating device and an electronic device using the sound generating device. Background technique [0002] As we all know, a speaker usually includes a basin frame, a vibration system housed in the basin frame, and a magnetic circuit system that drives the vibration system to vibrate. The vibration system usually includes a diaphragm and a voice coil that drives the diaphragm to vibrate. The diaphragm and the basin frame are glued and bonded However, when the diaphragm is installed in this structure, the glue between the diaphragm and the basin frame is easy to overflow, and the overflowing glue is easy to squeeze the ring of the diaphragm after being squeezed. acoustic performance. [0003] In order to solve the above-mentioned problems, a speaker module is proposed in the related art, which includes a first folding ring that is recessed dow...
