摘要
The present disclosure provides a sounding device including a holder, a vibration system fixed to the holder, and a magnetic circuit system configured to drive the vibration system to vibrate and sound. The vibration system includes a diaphragm fixed to the holder and a voice coil that drives the diaphragm to vibrate. The magnetic circuit system has a magnetic gap in which the voice coil is inserted. The voice coil includes voice coil wire layers that are formed by winding a voice coil wire and include an intermediate layer, an outer layer, and an inner layer. Ends of the voice coil wire layers away from the diaphragm are aligned. A height of the outer layer and a height of the inner layer are smaller than a height of the intermediate layer. The intermediate layer is glued and fixed to the diaphragm.
