Claim 16:
17. An acoustic panel system, comprising:
a perforated first skin;
a second skin; and
a core connected to the perforated first skin and the second skin, the core including a plurality of chambers and a first constriction;
each of the plurality of chambers extending vertically through the core to the perforated first skin and the second skin, and the plurality of chambers comprising a first chamber;
the first constriction dividing the first chamber into a first sub-chamber and a second sub-chamber, the first constriction comprising an aperture that fluidly couples the first sub-chamber to the second sub-chamber, and the first constriction actuatable between a first configuration and a second configuration, wherein a size of the aperture when the first constriction is in the first configuration is different than the size of the aperture when the first constriction is in the second configuration; and
an actuator configured to actuate deformation of the first constriction;
wherein the first constriction includes and extends vertically between a first end and a second end;
wherein the first end is attached to a sidewall of the first chamber; and
wherein the second end is not attached to the sidewall of the first chamber such that the second end is configured to move laterally away from the sidewall of the first chamber when the first constriction is actuated by the actuator.
