Loudspeaker module and assembling method of loudspeaker module

Abstract

The invention discloses a loudspeaker module and an assembling method of the loudspeaker module, and relates to the technical field of electroacoustic products. The structure of a module shell is improved, ultrasonic welding is carried out between shell bodies first, then a single loudspeaker is installed in an inner cavity of the module, and a front acoustic cavity is sealed through gluing at last. The defects caused by the fact that in the prior art, the single loudspeaker is installed first and then ultrasonic welding is carried out are effectively overcome, the phenomena that the single loudspeaker is damaged, the shell bodies deform or break and the front acoustic cavity and a rear acoustic cavity leak air in the assembly process cannot occur, and the qualified rate of the loudspeaker module is high.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module and an assembly method of the loudspeaker module. Background technique [0002] The loudspeaker module is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. [0003] The loudspeaker module includes a shell, and a speaker unit is accommodated in the shell. The loudspeaker unit includes a vibration system and a magnetic circuit system; the shell of the module is usually composed of at least two plastic shells. When assembling the speaker module with this structure, the speaker unit needs to be fixed to one of the shells first, and then the two plastic shells are welded together by ultrasonic welding to complete the assembly of the speaker module. The above assembly process will cause damage to the speaker un...

AI Technical Summary

Problems solved by technology

[0004] 1. During ultrasonic welding, the speaker unit will often be damaged by the ultrasonic machine;

[0005] 2. For some speaker modules with insufficient height and space, the housing will be squeezed by the speaker unit during ultrasonic welding, and the plastic housing is prone to deformation or even rupture;

[0006] 3. Since ultrasonic welding is achieved by high-frequency vibration, the sealant applied around the speaker unit to seal the front and rear acoustic chambers of the module will fail under the action of high-frequency vibration, resulting in the failure of the module. The seal between the front acoustic cavity and the rear acoustic cavity is not tight, and there is air leakage

[0007] For the above technical problems, there is no good solution in the industry
