PROBLEM TO BE SOLVED: To reproduce a sound of high sound quality by improving an available opening angle range of a subcone and reducing disturbance to radiation of a sound wave from a main diaphragm even when a speaker system is made more compact, thinner, and more lightweight than conventional one and provided with the subcone. SOLUTION: The speaker system 100 is provided with a diaphragm (first diaphragm) 8, and the subcone (second diaphragm) 110. The diaphragm 8 has an inner peripheral edge 8a coupled to a voice coil bobbin 6 and an outer peripheral edge 8b coupled to a frame 5 through an edge 9, and a peak part 8c is formed between the inner peripheral edge 8a and outer peripheral edge 8b, which are disposed on a sound radiation side as compared with the peak part 8c. The subcone 110 has an inner peripheral edge coupled to the voice coil bobbin 6, and is disposed on the sound radiation side of the diaphragm and in a cone shape which is opened to the sound radiation side. Even when the subcone is provided, therefore, the availability of the opening angle of the subcone is improved. COPYRIGHT: (C)2008,JPO&INPIT
