Abstract
The present application provides a speaker box and a stylus, and the speaker box includes a lower cover, an upper cover, a sounding driver, and side magnetic steels. The sounding driver includes a frame, a first frame, a vibration system fixed to the frame, and a magnetic circuit system to drive the vibration system. The magnetic circuit system includes a lower splint, a magnetic steel, a pole core formed with a projecting portion, and a first sub-magnetic steel. The magnetic steel includes a main magnetic steel and sub-magnetic steels arranged around the main magnetic steel and spaced apart to form a magnetic gap. The vibration system includes a diaphragm, a voice coil, a first diaphragm, and a first voice coil. The side magnetic steels are magnetized in an opposite direction to the sub-magnetic steels. The speaker box in this application can avoid inaccuracies in the stylus stroke.
