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

Abstract

The invention discloses a loudspeaker unit and an electronic terminal, the loudspeaker unit comprises a shell assembly, a magnetic circuit system, a vibration system and a balance assembly, the balance assembly comprises a centering support chip, the centering support chip comprises an outer fixing part, an elastic support part and a connecting section, and the outer fixing part is annular; the elastic supporting part is annular and located on the inner side of the outer fixing part. The connecting section is located between the outer fixing part and the elastic support part and connected withthe outer fixing part and the elastic support part. The outer fixing part is connected with the shell assembly, the elastic support part is located in the gap and partially connected with a support of a vibration system, and the elastic support part elastically deforms along with vibration of a support. The invention aims to provide the loudspeaker unit which can effectively prevent a bending part of the centering support chip from being easily broken, so that the loudspeaker unitcan effectively reduce the product reliability risk.

Description

technical field [0001] The invention relates to the technical field of acoustic and electric products, in particular to a loudspeaker unit and an electronic terminal using the loudspeaker unit. Background technique [0002] The loudspeaker is an important acoustic component of portable electronic equipment. It is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. At present, with the continuous advancement and innovation of technology, the structural design of loudspeakers is also constantly seeking innovation and change. It not only needs to meet the development trend of thinning, but also pays more and more attention to performance optimization, and takes into account the simplification of the process and the cost control. [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...
