Abstract
Provided is a speaker device, including a first frame, a first vibration system, a magnetic circuit system, a second frame, a second vibration system, a second voice coil, and a conductive member. The magnetic circuit system includes a lower splint, a first main magnetic steel, a first sub-magnet steel, a first pole core, a second sub-magnetic steel, and an upper splint. The conductive member includes an external conductive disk, two extension wall, and two connecting walls formed by bending and extending the two extension walls and spaced apart from each other. The connecting walls are used to act as welding pads, and a positive terminal and a negative terminal of the second voice coil are electrically connected to the two connecting walls, respectively. Compared with the related art, the acoustic performance of the speaker device of the present application is superior.
