Zusammenfassung:	A plurality of heat conduction bodies comprising a metallic material are located with a space held between each other, and attached with a connection with at least one of a voice coil bobbin comprising an insulating material and a voice coil. Further, one end of each heat conduction body is connected to a center cap comprising a metallic material. When the voice coil generates heat, the heat can be radiated by transmitting it to the center cap through the heat conduction body. Additionally, the heat conduction body with a shape of band is attached with a space held between each other, and the voice coil bobbin is formed with an insulating material, so that an eddy current caused by a magnetic field in a magnetic gap can be restrained from occurring.
