Abstract
The present disclosure discloses a sound device including a frame, a magnet system, and a vibration system; the vibration system includes a diaphragm and a coil fixed to the diaphragm; the diaphragm includes a rectangular dome and an edge surrounding the dome; the dome includes a first protrusion, a second protrusion and a third protrusion recessed towards the coil; the first protrusion extends along a long axis of the dome; the second protrusion extends along a short axis of the dome; two ends of the third protrusion connects with the first protrusion and the second protrusion, respectively; the coil is fixed to the first protrusion and the second protrusion. The third protrusion is located at the corner position and in an arc shape. The third protrusion can effectively reduce the risk of fracture of the dome during vibration deformation and improve the stability of the sound device.
