Abstract

The invention discloses a manufacturing method of a magnetic circuit assembly, the magnetic circuit assembly and a loudspeaker, and the manufacturing method of the magnetic circuit assembly comprisesthe steps: providing a die which comprises a female die and a male die which are matched with each other, and the female die is provided with a profiled groove; the washer, the first magnetic mixtureand the magnetic conductive block are stacked in the profiled groove; and the male die slides along the profiled groove and is matched with the groove wall of the profiled groove to press the washer,the first magnetic mixture and the magnetic conductive block into a whole to form a magnetic circuit assembly. According to the manufacturing method of the magnetic circuit assembly, the magnetic circuit assembly with a stable and reliable structure can be obtained.

Description

technical field [0001] The invention relates to the technical field of sound generating devices, in particular to a manufacturing method of a magnetic circuit assembly, a magnetic circuit assembly and a loudspeaker. Background technique [0002] The magnetic circuit assembly of the speaker drives the movement of the voice coil of the speaker, and drives the vibration mode to vibrate and produce sound through the voice coil. The reliability of the structure of the magnetic circuit assembly determines the sound quality of the speaker to a certain extent. [0003] In the related technology, the magnetic circuit units in the magnetic circuit assembly need to be connected and fixed by glue. When the magnetic circuit units are assembled, they need to go through multiple glue-coating assembly processes, and it is difficult to maintain the magnetic circuit units when assembling. Higher concentricity affects the sound quality of the speaker. Contents of the invention [0004] The ...
