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 comprising the sounder. The sounder comprises a shell; a magnetic circuit system positioned in the shell; wherein the magnetic circuit system comprises a side magnetic part and a central magnetic part; the central magnetic part comprises a support plate located in the middle. The sounder also comprises two central magnets positioned on two sides of the supporting plate. Central magnetic parts are of central hollow structures. The sounder also comprises two groups of vibration assemblies positioned on two sides of the support plate; each group of vibration assembly comprises a vibrating diaphragm and a voice coil; the sounder further comprises a centering structure located on the inner side of the central hollowed-out edge of thecentral magnetic part, the centering structure comprises two annular frameworks which are fixedly connected to the central parts of the two vibrating diaphragms, the adjacent ends of the two annular frameworks are fixedly connected with elastic supporting pieces, and the outer side edges of the elastic supporting pieces are fixedly connected to the central magnetic part of the hollowed-out edge. Polarization generated when double vibrating diaphragms in the bidirectional sounder structure vibrate can be reduced, product distortion is reduced, and product performance and stability are improved.

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...
