Abstract
The present disclosure provides an improved speaker including a suspension accommodated in a magnetic gap formed by a main magnet and an auxiliary magnet. The suspension is used for supporting a coil assembly of the speaker. The auxiliary magnet further includes a capacity-increased space for accommodating the suspension and providing the suspension with more space to vibrate and providing the suspension with better flexibility. In order to more firmly fix the suspension, the auxiliary magnet further includes a fastening slot for engaging with an edge of the suspension. Optionally, the auxiliary magnet is configured to be a two-piece structure.
