Abstract

The present application provides a speaker device and a stylus, and the speaker device includes: a first frame, a first vibration system, a magnetic circuit system, a second frame, and a second vibration system. The magnetic circuit system includes a first splint, a first magnetic steel unit, a second splint, a center splint, and a second magnetic steel unit; at least part of an edge of the first splint is provided with a first flip bent and extended in a direction close to the second splint, and/or at least part of an edge of the second splint is provided with a second flip bent and extended in a direction close to the first splint. The magnetic circuit system further includes side magnets fixed to the first splint or the second splint. The speaker device reduces the magnetic leakage and avoids the occurrence of non-linear strokes of a stylus.
