NOVELTY - The utility model claims a loudspeaker monomer and electronic device, comprising a dome, a voice coil and a diaphragm, the dome is located above the voice coil, the diaphragm is located on the peripheral side of the dome, the dome respectively connected with the voice coil and the diaphragm, the dome comprises an upper layer, a graphene layer, a lower layer, the graphene layer is located between the upper layer and the lower layer. when the loudspeaker continuously works, the voice coil will continuously heat, because the voice coil is connected with the ball top, the heat will be dispersed through the ball top, because the ball top is provided with a graphene layer, the heat of the voice coil can be quickly led into the ball top, so as to improve the radiating effect, so as to avoid the loudspeaker caused by heat in the continuous work, the ball top of the voice coil is dropped and so on, so it can improve the service life of the loudspeaker and convenient for miniaturization design. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic device.
