Sounding device and electronic equipment

Abstract

The embodiment of the invention provides a sounding device and electronic equipment. The sounding device comprises a vibration system, a magnetic circuit system and a shell; the shell comprises a mounting part having at least one end open and a rear cavity part which is correspondingly arranged on the outer side of a first side wall of the mounting part and is used for forming a rear cavity; the magnetic circuit system and the vibration system are fixed inside the mounting part; and a rear sound hole communicated with a magnetic gap in the magnetic circuit system and the rear cavity is configured in a position, directly facing the rear cavity, of the first side wall. The sounding device provided by the embodiment of the invention can have better performance while satisfying the small sizerequirement.

Description

technical field [0001] The invention relates to the technical field of sound generating devices. Background technique [0002] The sound generating device is an important component in electronic products, which is used to convert electrical signals into acoustic signals. Existing electronic products are becoming lighter and thinner, and the space reserved for the sound generating device is getting smaller and smaller, and the sound generating device is required to have better sound quality, especially higher and higher requirements are put forward for the stereo effect. [0003] In the existing technology, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are three main methods: one is to assemble a receiver at the upper end and a speaker module at the lower end.

Problems solved by technology

[0003] In the existing technology, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are mainly three methods: one is to assemble a receiver at the upper end and a speaker module at the lower end. This method exists The defect of low volume; the second is to assemble a speaker module at the upper and lower ends at the same time. Compared with the first method, the sound effect of this method is better, but the sealed rear cavity will occupy a large space, which is not conducive to the small size of the product The third is to assemble a speaker module at the lower end and a speaker with an open rear cavity at the upper end. Compared with the previous two methods, this structure has improved volume and occupied space, but the vibration of the rear shell of the mobile phone will be affected. more serious
