  • Patent number: 12641375
    Abstract: A speaker device (101, 201, 301) comprising a first diaphragm (103, 203, 303), an opposing second diaphragm (104, 204, 304), and a frame (102, 202, 302) comprising a first frame part (102a, 202a) on which the first diaphragm (103, 203, 303) is mounted and an opposing second frame part (102b, 202b) on which the second diaphragm (104, 204, 304) is mounted. A first speaker driver (105, 205, 305) drives the first diaphragm (103, 203, 303) and a second speaker driver (106, 206, 306) drives the second diaphragm (104, 204, 304). The first frame part (102a, 202a), a movable first coil bracket (107) of the first speaker driver (105, 205, 305), and a resilient first damper member (111) form a first single piece integrally formed unitary component. The second frame part (102b, 202b), a moveable second coil bracket (109) of the second speaker driver (106, 206, 306) and a resilient second damper member (112) form a second single piece integrally formed unitary component.
