NOVELTY - An integrated speaker driver claimed by the utility model, comprises a metal column and disc-shaped metal conducting magnet at the middle of the metal column, metal post and a disc-shaped metal guide magnet are combined with each other to form an integral structure; the middle part of the metal column body is provided with a through hole; bottom of the metal column body is fixed with a heat dissipation aluminium plate, heat dissipation aluminium plate is provided with multiple side wall of the through hole; the through hole radiating fin and corresponding to the through hole at the bottom of the extended with heat dissipation aluminium sheet; heat dissipation aluminium sheet is inserted in the through hole, and the bottom wall of the bottom side wall and the through hole of the heat dissipation aluminium sheet in close contact, heat dissipation sheet is also coated graphene radiating coating. The structure further for conducting heat dissipation through the graphite heat dissipation coating on the heat dissipation aluminium plate, heat dissipation aluminium sheet, heat dissipation fin and the heat dissipation aluminium sheet, the better the heat dissipation performance, improve the using life of the speaker.
