Problems solved by technology

[0004] As a result, a two-way sounder composed of two sets of vibration systems and a magnetic circuit system has emerged. Due to its own structural design characteristics, the two-way sounder vibrates in different directions at the same time during operation, and the polarization of the product is very high. Serious, and the sounder will have a peak on the frequency response curve near its lowest resonance frequency, which is easy to cause distortion due to excessive vibration of the diaphragm

Abstract

The invention discloses a sounder and an electronic product including the sounder, comprising: a housing; a magnetic circuit system located in the housing; the magnetic circuit system includes a side magnetic part and a central magnetic part; the central magnetic part includes a Support plate; and two central magnets located on both sides of the support plate; the central magnetic part is a central hollow structure; two sets of vibration components are located on both sides of the support plate, each set of vibration components includes a diaphragm and a voice coil; sound The device also includes a centering structure located on the inner side of the central hollow edge of the central magnetic part. The centering structure includes two ring skeletons respectively connected and fixed on the central parts of the two diaphragms. The adjacent ends of the two ring skeletons are connected and fixed with elastic supports. The outer edge of the elastic support is connected and fixed on the central magnetic part of the hollow edge. The invention can reduce the polarization generated when the double-diaphragm vibrates in the two-way sounder structure, reduce product distortion, and improve product performance and stability.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion. More specifically, it relates to a sounder and electronic products including the sounder. Background technique [0002] At present, a sound generator has been widely used as an important component of a terminal having an audio playback function. Some terminals, especially portable terminals, such as mobile phones, tablet computers, and earphones can provide very limited installation space for sound generators. Therefore, existing sound generators that can be applied to narrow installation spaces usually adopt a single diaphragm front-facing sounding structure . [0003] In recent years, with the rapid development of related technologies of electronic products, in order to achieve better performance, those skilled in the art have improved the structure and other characteristics of electronic products. [0004] As a result, a two-way sounder composed of two sets of vibration s...
