PURPOSE:To extend a low sound band sufficiently, by mounting a dynamic speaker to a cabinet other than the enclosed type cabinet, forming the 2nd compliance of the speaker system, splitting the cabinet with a partition in the cabinet, and fitting a field section for the partition plate. CONSTITUTION:The dynamic speaker having ring construction bodies 24, 25 supporting the diaphragm 21 and the field 31, is mounted to the cabinet 29, not the enclosed type, to form the 1st compliance of the speaker system determined with a part of the diaphragm 21 and the volume of the cabinet 29. Further, the 2nd compliance determined with a part of the diaphragm 21 and the separate space at the inside of the cabinet 29 is formed separately. In the 2nd compliance, the cabinet 29 is split with the partition plate 30 provided in the cabinet 29, the field section 31 is mounted to the plate 30, and the low sound reproducing frequency band is extended with the operation of the 2nd compliance. |
