SPEAKER DEVICE

摘要

A speaker device in which a diaphragm member radiates sound waves of the same phase in a considerably large range, has diaphragms, and uniformly transmits driving force to each diaphragm. The speaker device has a magnetic circuit (2); a first diaphragm (31) that has an outer peripheral part (31D) supported by a second diaphragm (32) and is supported by a drive member (33), at a joined part (312) that is located on the radially inner side of the outer peripheral part (31D); the second diaphragm (32) that has a support part (321) for supporting the rear side of the outer peripheral part of the first diaphragm (31) and also has an outer peripheral part vibratably supported by a frame (4); and the drive member (33) that has an inner peripheral part (33A) joined to a voice coil bobbin (37) and also has an outer peripheral part (33D) vibratably supported by the frame (4). The drive member (33) has a first diaphragm support part (331A) that supports, at a folded part (331), the rear side of the first diaphragm (31) and also has a second diaphragm support part (groove part (332), support part (333)) that is formed between the folded part (331) and the outer peripheral part (33D) and supports the second diaphragm (32).
