本文结合作者个人工作实践,从扬声器效率、灵敏度、质量因素及频响综合考虑,决定了合适的极隙磁通密度,提出了相应的永磁铁氧体磁体统一了工厂四种规格扬声器磁体、夹板及极芯尺寸。
According to the author’s personal working practice, considering the speaker’s efficiency, sensitivity, quality factor and frequency response, the appropriate pole gap flux density is determined. The corresponding permanent magnet ferrite magnets are proposed to unify the factory’s four kinds of speaker magnets, And the core size.
