Abstract

The present disclosure discloses a sounding device including a frame, a magnetic circuit system with a magnetic part and a vibration system. The vibration system includes a diaphragm fixed to the frame, a voice coil driving the diaphragm to vibrate and arranged around the magnetic part, and a metal shrapnel with conductive function. One end of the metal shrapnel is fixed to the frame and electrically connected to an external circuit, and the other end of the metal shrapnel is fixed to the voice coil and electrically connected to the lead wire of the voice coil. The metal shrapnel restrains a movement of the voice coil in a direction perpendicular to a vibration direction of the diaphragm. Compared with the related art, the sounding device disclosed by the present disclosure can reduce the number of elements to simplify the product structure.
