The present invention relates to the technical field of speaker production apparatuses, and more particularly, to a radial magnetic circuit assembling apparatus and assembling method. The radial magnetic circuit assembling apparatus is used for mounting an upper axial magnetic piece and a lower axial magnetic piece on an upper axial side surface and a lower axial side surface of multiple tile-shaped magnets. The radial magnetic circuit assembling apparatus comprises: a magnetic central pillar, a lower collar and an upper collar. The magnetic central pillar comprises: a large diameter section and a small diameter section that are connected sequentially and provided with limiting steps for evenly mounting the tile-shaped magnets in a circular manner. The lower collar is sleeved on the tile-shaped magnets in a direction from the large diameter section to the small diameter section and is used to restrict a radial displacement of the tile-shaped magnets. The upper collar is sleeved on the tile-shaped magnets in a direction from the small diameter section to the large diameter section, and presses and connect the upper axial magnetic piece and the lower axial magnetic piece to the upper axial side surface and the lower axial side surface of the tile-shaped magnets respectively. During assembling, each tile-shaped magnet is restricted by the lower collar and the upper collar in the radial direction and the axial direction respectively, so that machining difficulty can be effectively reduced, and production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of horn production devices, in particular to a radial magnetic circuit assembly device and an assembly method. Background technique [0002] With the continuous improvement of living standards, listening to music has become a way for people to relieve their mood and reduce stress in their spare time. At the same time, with people's continuous pursuit of high-quality life, people's requirements for the quality of sound components such as earphones and speakers are getting higher and higher. The manufacturer, starting from the combination of humanistic care and health concepts, in order to allow every user to listen to the pure sound of life in a noisy environment, has higher and higher requirements for low distortion of the speaker, and uses magnets for up and down magnetic conduction Compared with the traditional micro-speaker magnetic circuit structure, the micro-speaker with the magnetic circuit structure...
