Summary:PROBLEM TO BE SOLVED: To stably secure a wide reproduction frequency band from low-band to high-band even when a speaker system is made thinner. SOLUTION: The speaker system to be disclosed is provided with: a vibrating body 3 having a diaphragm 21, a voice coil 24, and a voice coil bobbin 23; a magnetic circuit 1 having a yoke 11, a magnet 12, and a plate 13; and a frame 2 which supports the vibrating body 3 and the magnetic circuit 1. In the speaker system, the diaphragm 21 has a folding part 21c between an inner peripheral edge 21a and an outer peripheral edge 21b. In addition, in the diaphragm 21, a conductive part 27 is formed between the inner peripheral edge 21a and the folding part 21c. COPYRIGHT: (C)2009,JPO&INPIT
