Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a speaker system capable of enhancing the heat dissipation effect and suppressing occurrence of eddy current. SOLUTION: A plurality of stripe thermal conductors 13 made of a metallic material are spaced from each other and are fitted while being in contact with at least either of a voice coil bobbin 7 and a voice coil 6 each made of an insulating material, and one end of each of the thermal conductors 13 is connected to a center cap 12 made of a metallic material. When heat is produced in the voice coil 6, the heat is conducted to the center cap 12 via the thermal conductors 13 are then dissipated. Further, the stripe thermal conductors 13 are spaced and fitted, the voice coil bobbin 7 is made of an insulating material to suppress occurrence of eddy current by the magnetic field in the magnetic gap.
