Loudspeaker unit and electronic terminal

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 is arranged corresponding to a gap, the balance assembly comprises a centering support chip made of FPCB material, the centering support chip comprises an outer fixing part, an elastic support part and a bonding pad structure, and the outer fixing part is connected with the shell assembly; the elastic supporting part is connected with the outer fixing part, located in the gap and partially connected with a support, and the elastic supporting part elastically deforms along with vibration of the support. The bonding pad structure comprises a cantilever and a bonding pad which are arranged at an included angle, one end of the cantilever away from the bonding pad is connected with the elastic supporting part, the cantilever extends along the support, the bonding pad is fixedly connected with the diaphragm or the top wall of the support, and a lead of the voice coil is electrically connected with the bonding pad. According to the loudspeaker unit provided by the invention, the structure of a voice coil in the magnetic gap is arranged more freely, and the volume of a magnetic circuit system is effectively increased, 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 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.
