According to the dome, the vibrating diaphragm and the loudspeaker provided by the utility model, the heat conduction layer and the heat dissipation layer are respectively arranged, and heat generated in the loudspeaker is conducted layer by layer, so that the heat is dissipated more uniformly; wherein the heat dissipation layer is provided with a through hole, so that hot air generated by a voice coil in the loudspeaker can be quickly dissipated through the through hole, cold air on the other side of the dome can penetrate through the through hole of the dome through vibration of the vibrating diaphragm to be quickly supplemented, and the flow speed of the air passing through the dome is accelerated; meanwhile, bosses are arranged on the heat conduction layer, the heat dissipation area of the heat conduction layer is increased, the heat dissipation performance is improved, the rigidity of the dome is improved, and high-frequency segmentation vibration is improved. And when the heat dissipation layer is arran
