Speaker modules and electronics

Abstract

The invention discloses a loudspeaker module and electronic equipment, wherein the loudspeaker module includes a module casing, a speaker unit, a first heat dissipation plate and a second heat dissipation plate, the module casing has a housing cavity; the loudspeaker unit is arranged in the housing cavity, and the receiving cavity is separated into a front sound cavity and a rear sound cavity, the rear sound cavity is provided with a flexible deformation part, the speaker module also includes an electronic equipment shell, and a closed cavity is formed between the electronic equipment shell and the module shell; the front sound cavity or The rear acoustic cavity is provided with a first opening, and the rear acoustic cavity is also provided with a second opening, the flexible deformation part covers the second opening, and the first opening and the second opening are located on the same side of the module shell; the first cooling plate covers the first opening It is provided that the second heat dissipation plate is located on the side of the flexible deformation portion facing the airtight cavity, is arranged to cover the second opening, and has a plurality of ventilation holes, and the second heat dissipation plate is integrally connected with the first heat dissipation plate. The technical scheme of the invention can improve the heat dissipation capability of the loudspeaker module.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a loudspeaker module and electronic equipment. Background technique [0002] The speaker module is an important acoustic device of portable electronic equipment, which is used to complete the conversion between the electrical signal and the acoustic signal. In order to achieve a better sound playback effect in a small cavity space, the Smart PA ( Smart power amplifier) ​​and tuning algorithm, but in the application process of Smart PA, the speaker module will work for a long time under high power conditions, which will increase the heat generated by the speaker module. The current speaker module is mainly through the shell The sound outlet on the speaker module is used for heat dissipation, the heat dissipation effect is poor, the high temperature in the speaker module cannot be effectively dissipated, and the risk of burning the speaker module voice coil is great...
