PROBLEM TO BE SOLVED: To provide a "speaker device" capable of interconnecting a duct and the external space without impairing bass reproduction capability.SOLUTION: A speaker device 1 includes a cabinet 4 from which a duct 2 for back pressure adjustment is projecting, a speaker unit 5 housed in the cabinet 4, and a relay cavity member 3 having first and second coupling parts 3a and 3b. A vehicle interior space S1, in which the cabinet 4 is installed, is partitioned from the vehicle exterior space S2 by a partition 20, but since a sub-frame 30 facing the partition 20 exists, the duct 2 cannot be coupled directly with an opening 21 provided in the partition 20. The relay cavity member 3 is disposed in a narrow space S3 between the partition 20 and a sub-frame 30, and after coupling the second coupling part 3b with the opening 21, the duct 2 is coupled with the first coupling part 3a. |
