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 is arranged corresponding to a gap, and the balance assembly includes a centering support piece made of FPCB material. The centering strut includes an external fixing part, an elastic supporting part and a pad structure, wherein the external fixing part is connected with the shell assembly; the elastic supporting part is connected with the external fixing part, the elastic supporting part is located in the gap and partially connected with the bracket, and The supporting part elastically deforms with the vibration of the bracket; the pad structure includes a cantilever and a pad arranged at an angle, the end of the cantilever away from the pad is connected to the elastic supporting part, the cantilever extends along the bracket, the pad and the diaphragm or the top of the bracket The wall is fixedly connected, and the leads of the voice coil are electrically connected to the pads. The loudspeaker unit of the present invention not only makes the structural setting of the voice coil in the magnetic gap more free, but also effectively increases the volume of the magnetic circuit system, so that the magnetic field intensity is higher and the acoustic performance is better.

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, the centering piece of the speaker unit is usually connected to the lower surface of the voice coil, which limits the structure of the voice coil in the magnetic ga...
