Abstract:
A speaker device includes a first speaker unit, a first cabinet that houses the first speaker unit, and an annular portion defining a sound path that guides sound radiated from the first speaker unit to outside the first cabinet, the annular portion being positioned on a sound radiation side of the first speaker unit and arranged so as to sound a diaphragm in the first speaker unit. The speaker device also includes a second cabinet arranged inside the annular portion and spaced apart from the sound path, the sound path being annular, and a second speaker unit that radiates sound in a direction in which the first speaker unit radiates sound and that is stored in the second cabinet. The speaker device further includes a resonant portion having an aperture communicating with the sound path and defining a resonant space.
