Problems solved by technology

[0002] With the rapid development of electronic equipment, higher requirements are placed on the sound quality and heat dissipation performance of speakers. Some electronic equipment adopts an all-metal solution to improve the rear cavity and heat dissipation performance. After adopting an all-metal solution, it is limited by the metal forming Process, the metal shell around the core cannot form a fixed wall structure like an injection-molded shell, resulting in the core not being able to be effectively fixed. After the product is subjected to mechanical experiments, the core is prone to glue problems, resulting in air leakage.

Abstract

The invention discloses a sound production device, which comprises a shell, a sound production single body and a fixing piece. The shell is made of a metal material and is provided with an accommodating cavity; the sound production single body is arranged in the accommodating cavity; the fixing piece is arranged in the containing cavity and provided with a limiting groove, and the sound production single body is limited in the limiting groove; and the fixing piece is provided with a first connecting part connected with the shell and a second connecting part connected with the sound production single body. The sound production unit is limited and fixed by arranging the fixing piece, so that the stability and the reliability of the sound production unit are improved.

Description

technical field [0001] The invention relates to the technical field of acoustic-electric conversion, in particular to a sound-generating device. Background technique [0002] With the rapid development of electronic equipment, higher requirements are placed on the sound quality and heat dissipation performance of speakers. Some electronic equipment adopts an all-metal solution to improve the rear cavity and heat dissipation performance. After adopting an all-metal solution, it is limited by the metal forming Process, the metal shell cannot form a fixed wall structure around the core like an injection-molded shell, resulting in the core not being able to be effectively fixed. After the product undergoes mechanical experiments, it is prone to the problem of core glue opening, resulting in air leakage. Contents of the invention [0003] The main purpose of the present invention is to propose a sound-generating device, aiming at improving the stability of the sound-generating ...
