The present disclosure discloses a sounding device including a frame, a vibration system, a magnetic circuit system, and an air-permeable mesh in a ring shape. The vibration system includes a diaphragm and a voice coil. The magnetic circuit system includes a yoke, a first magnet, and a second magnet in a ring shape around and spaced apart from the first magnet for forming a magnetic gap. One end of the air-permeable mesh is fixed to the second magnet, and another end of the air-permeable mesh is fixed to the frame. A rear cavity is formed jointly by the frame, the yoke, the second magnet and the air-permeable mesh. Compared with the related art, the sounding device disclosed by the present disclosure has a better low-frequency acoustic performance.
