Abstract

Disclosed in the present invention are a sound generation apparatus and an electronic device. Said apparatus comprises: a magnetic circuit system, the magnetic circuit system comprising a side magnetic circuit portion; a vibration system, the vibration system comprising a diaphragm and a voice coil connected to the diaphragm, the diaphragm comprising an edge portion located at an edge; and a heat conduction system, the heat conduction system comprising a metal structure member provided around the voice coil, the metal structure member being spaced from the voice coil, the metal structure member being provided between the edge portion and the side magnetic circuit portion, and the specific heat capacity of the metal structure member being less than or equal to 0.8 kJ / kg•K.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a sound generating device and electronic equipment. Background technique [0002] Micro speakers are usually composed of a vibration system, a magnetic circuit system, and a support system. The vibration system includes diaphragm, dome, voice coil, centering piece and so on. The magnetic circuit system includes a washer, a magnetic yoke and several magnets. The support system includes shells, shrapnel and other inserts, etc. [0003] The casing is mostly an injection molded part, and the metal insert is injected into the casing by an insert injection molding process. The process of this method is complicated, the cost is high and the yield is low. [0004] In addition, such a case has a poor heat dissipation effect. [0005] In addition, microspeakers generally also include a housing. The vibration system, the magnetic circuit system and ...
