NOVELTY - This utility new type claims a one speaker, this loudspeaker comprise at least one voice coil, the voice coil comprising voice coil framework and winding wire, inner surface and/or outside surface of the voice coil framework set with the first radiating layer, a first radiating layer a graphene thin film. This new type utility also claims a one audio play device, this audio play device comprising the speaker. This utility new type through set with graphene thin film in sound coil skeleton of the voice coil in the speaker inner surface and/or outside surface, the graphene thin film with thermal conductivity, use graphene thin film is attached can increase the thermal conductivity of the voice coil in inner surface of the voice coil framework and/or outside surface, so as to increase radiating property of the speaker so as to increase sound effect of audio play device.
