Abstract (en)
A thin speaker with a voice coil having a damper function, includes a frame, a magnetic device, a damper voice coil and a diaphragm. The damper voice coil comprises a holding member and a conductive member. The holding member includes a holding base and two holding suspension portions formed on two ends of the holding base. The conductive member includes a conductor wound to form a first winding at one side of the holding base and a second winding at the other side of the holding base, and two conductive suspension portions formed on two ends of the conductor and located on the top of holding suspension portions. Since the damper voice coil has the functions of a damper and a voice coil, the present invention is capable of maintaining a thin design and ensuring the up and down movements of the holding base to prevent its deflection.
