Loudspeaker monomer and electronic terminal

Abstract

The invention discloses a loudspeaker unit and an electronic terminal. The loudspeaker unit includes a shell assembly, a magnetic circuit system, a vibration system, and a balance assembly. The balance assembly includes a centering strut, and the centering strut includes: an outer A fixing part, an elastic supporting part and a connecting section, the outer fixing part is ring-shaped; the elastic supporting part is ring-shaped and is located inside the outer fixing part; the connecting section is located between the outer fixing part and the between the elastic support parts, and connect the external fixing part and the elastic support part; the external fixing part is connected with the housing assembly, and the elastic support part is located in the gap and partly connected with the bracket of the vibration system connected, the elastic support part elastically deforms with the vibration of the bracket. The purpose of the present invention is to provide a loudspeaker unit that can effectively prevent the bending part of the centering strut from being easily broken, so that the loudspeaker unit can effectively reduce the risk of product reliability.

Description

technical field [0001] The invention relates to the technical field of acoustic and electrical products, in particular to a speaker unit and an electronic terminal applying the speaker unit. Background technique [0002] Speaker is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signal and sound signal, and is an energy conversion device. At present, with the continuous progress and innovation of technology, the structural design of loudspeakers is also constantly seeking innovation and change, which not only needs to meet the development trend of thinning, but also pays more and more attention to the optimization of performance, and takes into account the simplification of the process and the cost control. [0003] In the related art, a centering support piece is fixed on the vibration system of the speaker unit to prevent the vibration system from polarizing in a non-vibration direction during t...

AI Technical Summary

Problems solved by technology

[0003] In the related art, the vibration system of the loudspeaker unit is fixedly provided with a centering strut to prevent the vibration system from being polarized in the non-vibration direction during the vibration process. In order to lengthen the length of the vibration arm, the centering strut is designed to bend back More, resulting in more concentrated stress at the bend of the vibrating arm, which increases the risk of breaking the vibrating arm
