Problems solved by technology

[0003] However, when the plastic shell is used as the assembly process benchmark for assembly, due to the warping and deformation of the plastic shell, it is difficult to ensure accurate positioning of the straight edge on the plastic shell, and the assembly position of the diaphragm, voice coil, magnetic circuit components and other components will be deviated. , the accumulation of errors caused by the assembly of various components will make the position of the voice coil in the magnetic circuit system unstable, especially the concentricity of the magnetic circuit components and the voice coil is difficult to guarantee, which will lead to abnormal performance such as polarization, resulting in unstable acoustic performance

Abstract

The invention relates to a loudspeaker and a loudspeaker assembling method. The loudspeaker comprises a shell, a rigid ring, a vibration system arranged on the shell and a magnetic circuit system matched with the vibration system, wherein the shell comprises an outer shell and a front cover; the vibration system comprises a vibrating diaphragm and a voice coil which is connected to the vibrating diaphragm; an outer ring of the rigid ring is provided with a reference structure serving as a process reference; the rigid ring is connected to a fixing part of the vibrating diaphragm and surrounds the periphery of the vibrating diaphragm; the voice coil is connected to the center of the vibrating diaphragm; the rigid ring and the vibration system form a vibration module; and the vibration moduleand the magnetic circuit system are assembled in the outer shell under the technological reference established by the reference structure. According to the loudspeaker and the loudspeaker assemblingmethod, the technical problem that a plastic part reference in the prior art is replaced by the rigid ring is solved, the reference structure on the rigid ring is used as a uniform assembly reference,so that the relative position between all the components can be effectively guaranteed, and the stability of the reference of the rigid ring is good, and thus the acoustic performance stability of the loudspeaker is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic conversion devices, and in particular, the invention relates to a loudspeaker and a loudspeaker assembly method. Background technique [0002] When the existing loudspeaker is assembled, the positioning of components such as the diaphragm, voice coil, and magnetic circuit components is usually realized by setting a positioning straight edge on the plastic shell as an assembly process reference. The diaphragm, voice coil, magnetic circuit assembly and other components are assembled as a single piece. [0003] However, when the plastic shell is used as the assembly process benchmark for assembly, due to the warping and deformation of the plastic shell, it is difficult to ensure accurate positioning of the straight edge on the plastic shell, and the assembly position of the diaphragm, voice coil, magnetic circuit components and other components will be deviated. The accumulation of errors ca...
