Abstract: A sound generator provided in the present disclosure includes a frame, a magnetic circuit unit, and a first vibration unit and a second vibration unit arranged on two sides of the magnetic circuit unit. The magnetic circuit unit includes a first central magnetic yoke in the middle, a central magnet fixed to the first central magnetic yoke, a magnetic component arranged around the central magnet and fixed to the frame, and a connecting portion connecting the first central magnetic yoke to the magnetic component. The central magnet includes a first magnet portion fixed to the first central magnetic yoke and a second magnet portion fixed to the side of the first magnet portion away from the first central magnetic yoke, a projection area of the first magnet portion along a vibrating direction is greater than a projection area of the second magnet portion along the vibrating direction.

Abstract: The present disclosure discloses a sound device includes a frame, a magnet system, and a first vibration system and a second vibration system arranged on two sides of a magnet system. The magnet system includes a first central yoke, a central magnet mounted on the first central yoke, a side yoke surrounding the central magnet and fixed to the frame, and a connection portion connecting the first central yoke and the side yoke. The side yoke includes a first side yoke fixed to the frame and a second side yoke bending and extending from an edge of the first side yoke towards the central magnet; the connection portion connects the first central yoke and the second side yoke. The sound device in the present disclosure has higher magnetic ability and miniaturization ability.
