Abstract
A speaker includes a base defining a pair of receiving cavities separated from each other in a longitudinal direction and an engaging portion disposed between the pair of receiving cavities, a pair of magnetic circuit systems received into the pair of the receiving cavities, a diaphragm attached on the base, a pair of voice coil members connecting with the diaphragm, and a suspension mounted on the base. The suspension defines a pair of separating portions separated from each other in a lateral direction. Each separating portion defines a fixing portion engaging with the engaging portion of the base, a pair of connecting portions extending from two ends of the fixing portion and towards the diaphragm, and a pair of supporting portions connecting with the connecting portion for engaging with the pair of voice coil members, respectively.
